- * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
- dbxread.c to symmisc and change name to add_psymbol_to_list.
- Ditto for add_psymbol_addr_to_plist(). Also expand their
- body to not use ADD_PSYMBOL_VT_TO_LIST.
+ * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
+ xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
+ Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
- * dwarfread.c: Remove add_psymbol_to_list() and convert usages
- to the ADD_PSYMBOL_TO_LIST macro.
+Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
- * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
- to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
+ * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
+ no longer any need to copy ../include/opcode/* into gdb.
- * partial-stab.h, symfile.h: Move definitions of the macros
- ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
- partial-stab.h to symfile.h. They aren't stab specific.
- Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.

-Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
+ * i860-tdep.c: Update with with numerous changes received
+ from current maintainer (Peggy Fieland).
- * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
- * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
- Include <opcode/FOO.h> instead of <FOO-opcode.h>.
+Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
- * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
- dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
- allocated when it is needed. Until it is needed, it points
- to a shared statically allocated structure.
+ * valprint.c (type_print_base, type_print_method_args):
+ Print C++ constructor methods without bogus "return type."
- * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
- in read_ofile_symtab to recognize two initial N_SO stabs,
- and let process_on_symbol handle it. This is cleaner, more
- efficient, and lets mipsread.c share the same code.
+Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
- * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
- and related macros to here ...
- * dbxread.c: ... from here.
- * symmisc.c: Move the "overflow" handling from
- ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
- * dwarfread.c: Re-write add_psymbol_to_list to use
- ADD_PSYMBOL_VT_TO_LIST macro.
+ * infptrace.c (child_xfer_memory): Parameter "target" should
+ be a pointer to a structure, not the entire structure.
- * mipsread.c: Extend mipsread.c to handle stabs-style symbols
- encapsulated in ecoff symbols. This enable full g++ debugging.
- * partial-stab.h: Move the code for pre-scanning symbols
- and building psymtabs to an include file, out from dbxread.c.
- This way, the same code can also be used by mipsread.c.
- * dbxread.c, buildsym.h: Various changes to allow some functions
- to be used by mipsread.c (also some arguable stylistic changes).
+Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
- * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
- since mips-tfile puts relocatable addresses into LBRAC/RBRAC
- stabs.
+ * depend: Convert the couple of references to ansidecl.h that
+ used the local gdb version to use the ../include version.
- * mipsread.c: Replace code to handle ambiguous tag blocks.
- Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
- at types and offsets) if a tag is a struct, union, or enum.
- Still patch it later if we find out for sure.
- * mipsread.c: In various ways, replace Forin's
- ideo-syncratic code by code that fits better with the
- rest of gdb, for both stabs-based and ecoff-based symtabs.
- E.g. use end_psymtab; don't do extra passes over FDR table to
- pre-partition global data; don't use external symbols to
- create static/global symbols (just put them in the
- misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
- sort psymtabs or symtabs; use obstacks more.
+Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
- * symtab.c, mipsread.c, dbxread.c, buildsym.c:
- ANSIfy: Replace bcopy by memcpy, bzero by memset.
+ * procfs.c
+ (child_xfer_memory): Takes pointer to a struct, not entire struct.
+ (inferior_proc_init): Fix non-ANSI version of args.
+ (attach): Call print_sys_errmsg with correct number of args.
+ (mappingflags): Make static, does not need to be global.
-Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
+ * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
+ not the entire struct itself.
- * solib.c (locate_base): Fix uninitialized variable that was
- causing return of random value to callee.
+ * valops.c (value_assign): Cast some args to modify_field() and
+ {read,write}_register_bytes() correctly.
- * config/mh-amix, config/mh-i386v4: Change to find alloca by
- compiling and linking alloca.c, even when it is not strictly
- required. Also arrange to link with -ltermlib rather than
- -ltermcap.
+ * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
- * Makefile.in: Move TERMCAP definition to prior to inclusion
- of host makefile fragments so it can be overridden.
+ * Makefile.in (MALLOCSRC): Removed reference to removed local
+ copy of ansidecl.h.
-Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)

+ * main.c (main): Make option_index local to keep new getopt happy.
+ main.c, solib.c, Makefile.in: Update copyright notices.
- * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
- so compiles with native compilers (without builtin alloca) can
- pick up the version from the bsd emulation library. However, we
- search the standard C library first so we don't pick up lots of
- other broken stuff from libucb.a, that we *don't* want.
+Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
- * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
- Change svr4 references to sysv4.
+ * cplus-dem.c (cplus_demangle): Correctly demangle destructors.

- * solib.c: Completely reorganized (rewritten) to support
- SVR4 shared libraries in a manner very close to the original
- SunOS implementation. This support is expected to change and
- become more general at some future time. The SVR4 version
- does not yet work for attached processes, for example.
+ * solib.c (solib_add_common_symbols): Only compile in when not
+ using SVR4 style shared libraries.
- * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
- relocation address to be valid whether or not symbols are
- being read from a shared library or an executable. Use the
- relocation address recorded in the psymtab when reading
- full symbol tables (in read_ofile_symtab). Ensure that the
- relocated address ranges are recorded in partial symtabs.
+Tue Jan 14 22:34:00 1992 Fred Fish (fnf at cygnus.com)
- * elfread.c: Add new function elf_interpreter() to return the
- string from the ELF ".interp" section. This is the interpreter
- that the kernel tries to run and feed the executable to.
- Expand arguments to record_misc_function to include a type arg.
- Modify elf_symtab_read() to supply the type arg, and to do symbol
- relocations for symbols read in from shared libraries.
+ * dwarfread.c (locval): Add offreg flag to indicate location
+ values that are computed off a base register.
- * procfs.c: Add new functions proc_base_address() and

+ within function scopes.
- * tm-svr4.h: Add macros to support SVR4 shared libraries.
- Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
- CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.

+ doesn't exist on some systems.
- * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
- unused START_INFERIOR_HOOK.
+ * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
+ nexting over recursive function calls.
- * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
- to account for slow loading from floppies.
- (eb_create_inferior): New fn, from eb_start and
- nindy_create_inferior.
- (eb_close): Only use log_file if nonzero.

- (eb_kill): A new no-op.
- (eb_mourn_inferior): Remove breakpoints, then generically weep.
+ * target.c (target_read_string): Create this routine to read null
+ terminated strings from the target. It deals with running off the
+ end of memory elegantly as well. solib.c (find_solib): Use
+ target_read_string() to avoid problems with running off the end of
+ memory.
-Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
+ * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
+ that reference pgrp_inferior.
- * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
- miscellaneous comparisons of integer with NULL that elicit
- compiler warnings about comparison of integer with pointer, when
- NULL is ((void *) 0) rather than just a bare 0.

+Thu Jan 2 15:07:41 1992 John Gilmore (gnu at cygnus.com)
- * i386-tdep.c: Fix a problem on i386 systems where buffered code
- stream access was failing to take into account the minimum size
- granularity of the code section. For now, the buffering is simply
- disabled. There is a similar problem in the i386 disassember code
- that has not yet been fixed (FIXME).
+ * sparc-pinsn.c: Rename bitfields that overlap with macro names
+ in ../include/opcode/sparc.h.
- * gmalloc.c: Use macros to hide some of the ugly casting required

+ value_copy().
- * inflow.c (terminal_inferior): Avoid error msg if attached.

- * gmalloc.c: Fix bug that causes malloc & free to
- fail on systems where pointers have the high bit set (0x800efcf0
- for example). The problem is that the difference between two
- pointers is a signed integer, so the computation
-
- (char *) 0x800efcf0 - (char *) 0
-
- yields a negative value. The sign of the result of the modulus
- operator is machine dependent for negative operands, thus it is
- possible for it to end up negative. From Fred Fish.

-Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
-
- * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
- added clean-info. added some standards.text support and made it

- terminals back and forth if we don't have one.
-
- * c-exp.y (parse_number): Zero is not an unsigned int constant!
- * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
-
- Improve type parsing.
- * buildsym.c (define_symbol, read_range_type): Add
- long_kludge_name that passes the names of range types being
- defined, down to where we must choose between 'int' and 'long'
- variants. This fails on Sun C anyway since the compiler itself is
- confused between int and long.
- (read_array_type, cleanup_undefined_types): Correct the size of
- array type whose element-type size isn't immediately known.
-
- Early preparation to blow away many builtin types, building them

- formatting.
- * xcoffexec.c: Change syms_from_objfile caller.

- general solution.
-
-Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
-

- * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
- mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
- are created in place, so the mv fails, then the make continues.
-
-Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
-
- Add C++ as a separate language.
- * defs.h (enum language): Add language_cplus.
- * dwarfread.c (end_symtab): Support language_cplus.
- * c-exp.y: Add new struct language_defn cplus_language_defn.
- Don't set c to be the default language (see main.c).
- * c-exp.y (yylex): Only look for field of this if
- language is C++. (First difference from C!)
- * language.c: Add case branches for C++ (currently, all
- the same as C). Also, add c++ to "usage" note for "set lang".
- * valprint.c (typedef_print). Add case branches for C++.
- * main.c (main): New way to set initial language: Look at
- file extension of psymtab containing main(). (Same as we
- do for symtabs, but avoid loading the symtab yet.)
- * symtab.c: New routine find_main_psymtab(), used by main()
- to set initial language.
- * symfile.c (allocate_symtab): Move code for mapping file
- extensions-> languages to new deduce_language_from_filename().
-
- Fix a C++ problem when looking for methods in super-classes.
- There was confusion between base and derived types.
- * valops.c (value_fn_field): Change function interface.
- * values.c: Use new value_fn_field interface.
-
-Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
-
- * infrun.c: Fixed typo in comment.
- * utils.c: All the v*fprintf emulation is now in libiberty,
- so we can get rid of some junk.
- * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
- xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
- * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
- type operands, as used by branch instructions.
- * gmalloc.c: Fix prototype of memcpy.
- * elfread.c: Comment out register_addr, since it conflicts
- with the one in coredep.c.
- * buildsym.h: Remove extern declarations of two functions
- that are really static in buildsym.c.
- * tm-mips.h: Add symbolic names for more registers.
- * mips-xdep.c (store_inferior_registers): Use new register names.
- * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
- only used for core files, not ptrace. Therefore,
- the KERNEL_U_ADDR hack is no longer needed.
- The mapping to ptrace number is now in in mips-xdep.c.
- * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
- mapping from the old REGISTER_U_ADDR), and use it
- in {fetch,store}_inferior_registers.
- * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
- * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
- Save/restore FP regs correctly (?).
- * dbxread.c: Remove duplicate define_symbol and type_synonym_name
- (these had been previously moved to buildsym.c).
- Hence, define_symbol becomes extern instead of static.
- * buildsym.c (read_struct_type): Comment out bogus handling
- of C++ operator methods. Minor hacking of reading of class
- contexts. Make define_symbol non-static, so dbxread.c can call it.
-
-Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
-
- * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
- filename with error messages.
- * stack.c (frame_select_command): Rename to select_frame_command
- to avoid "fr" and "fra" having nonunique completions.
- * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
- (symfile_init): Print file format name when unable to handle it.
- (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
- * symmisc.c (free_symtab): Only free linetable if nonzero.
- * symtab.h: Remove obsolete BLOCKLIST macros.
-
-Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
-
- * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
- that stop_step is 1 at bottom of main loop. I don't know why this
- needs to be done, but it helps me sleep better at night.
-
-Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
-
- * main.c (initialize_history): Read history after reading all
- init files.
-
-Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
-
- * buildsym.c: Break out initial malloc sizes.
- (record_line): Record directly in a subfile. Alloc on demand.
- (compare_line_numbers): Add from xcoffread.c.
- (end_symtab): New params say whether to sort pendings and
- linetable. Patch block stabs if defined. Shrink linetable before

- global_stabs and file_stabs for xcoffread.
- * dbxread.c (start_subfile): Move to buildsym. Change above calls.

- * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
- tm-sparc.h: Accept fromleaf parameter.
- * c-exp.y (yyerror): Pass error message if given.
- * configure.in: Add rs6000 host and target.
- * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
- * symfile.h (entry_point): Add.
-
-Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
-
- * buildsym.c: New file. Breaks out symbol-table-building routines
- from dbxread.c, so they can be shared with xcoffread.c.
- * buildsym.h: New file. Declarations for buildsym.c users.
- * dbxread.c: Remove large chunks into buildsym.c.
- * Makefile.in: Add buildsym.c and buildsym.h.
-
- * symfile.c (syms_from_bfd): New routine.
- (add_symbol_file): Call it to do the real work.
- (syms_from_bfd): Initialize entry_point before calling symfile_init.
- * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
- Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
-
-Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
-
- * cplus-dem.c (cplus-demangle): added support for templates, static
- data, and the new (correct) mangling for destructors.
-
- * dwarfread.c: (dwarfwarn): created a varargs version of
- dwarfwarn, for non __STDC__ compilers.
-
- * c-exp.y: (yylex): added match for "template" token.
- (typebase): added TEMPLATE name '<' type '>' clause, for explicit
- specification of template types.
-
- * symtab.c: (lookup_template_type): new function for finding
- templates in symbol table.
- (type_name_no_tag): changed to explicitly check for s/u/e at the
- beginning of the symbol - if it is a template, none of these will
- be there (but the name will still contain spaces.)
-
-Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
-
- Various fixes to improve g++ debugging.
- * symtab.h: Add is_const and is_volatile flags for each method.
- These are bit fields - take their space from voffset,
- which shrinks to 30 bits. Since voffset is now a bitfield,
- make it unsigned for portability. This changes its interpretation
- slightly: Static methods now have voffset 1 instead of -1,
- and virtual offsets start at 2, not 1.
- * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
- since it now returns an entire magled method name, not just
- the type part. This avoids some duplication.
- It also allows us to correctly mangle const and volatile
- methods (using the new is_const and is_volatile bit fields
- mentioned above).
- * valprint.c (type_print_base), values.c (check_stub_method):
- Simplify by using new gdb_mangle_name.
- * values.c (value_headof): Fix to correctly handle single
- inheritance (actually two fixes, either of which suffices).
- * dbxread.c (read_struct_type): Handle const and volatile
- method specifiers.
- * dbxread.c (read_struct_type): Yet one more place where
- we must handle '\\' continuations.
- * valprint.c (vtbl_ptr_name): Add final '\0'.
-
-Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
-
- * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
- short return values for sparc and 68k. Patch from Paul Eggert.
-
- * coffread.c, coredep.c, i386-xdep.c: install patches for
- SysV/386 3.2 from Mauro DePalma.
-
-Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
-
- * core.c (core_file_info), exec.c (exec_file_info): Print file
- type. Use printf_filtered.
-
- * valops.c (value_fetch_lazy): Avoid 0-length fetches.
-
-Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
-
- * dwarfread.c: Add casts to remove compiler warnings.
-
- * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
- tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
- tm-sun3.h: Remove locally duplicated code for calling functions
- in the inferior. The only differences were in the specific trap
- vectors used and whether or not an fpu was present. These are
- now handled by appropriate definitions of BPT_VECTOR and
- HAVE_68881 respectively. Other minor obvious cleanups.
-
- * valops.c: Correct a minor misspelling.
-
- * utils.c: Remove local BSD/USG hacks that are now in libiberty.
-
- * dwarfread.c: Remove prototype for dwarfwarn. Does not work
- with <varargs.h>.
-
-Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
-
- * stack.c (frame_command): Always print. Use new
- frame_select_command to select a frame without printing.
-
- * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
-
-Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
-
- * dwarfread.c: New file for DWARF debugging format support.
-
- * elfread.c: New file for ELF object file format support.
-
- * procfs.c: New file for SVR4 /proc (process file system) support.
-
- * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
- Amiga UNIX support.
-
- * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
-
- * xm-m68k.h: New file for host machines with m68k cpu.
-
- * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
- Add elfread.o and dwarfread.o to OBS.
-
- * symfile.h: Add "elf" to list of supported formats in comment.
-
- * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
- types to gdb, builtin_type_long_double, builtin_type_complex, and
- builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
- TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
- TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
- TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
- types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
-
- * infrun.c: When using SVR4 /proc interface instead of ptrace(),
- call proc_set_exec_trap() to setup child to stop at first instruction.
-
- * inftarg.c: When using SVR4 /proc interface, call proc_wait()
- rather than wait().
-
- * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
- supply_fpregset(), and fill_fpregset(), which are machine
- dependent support routines for SVR4 /proc interface.
-
- * utils.c: Add warning_setup() and warning(). Warning() behaves
- the same as error() except that it returns normally rather than
- jumping back to command level. Modules that don't want to call
- warning() for some reason, but want to produce their own warnings,
- can call warning_setup() to ensure compatibility with the way
- warning() and error() deal with the terminal.
-
- * symtab.c: Make internal errors produce more useful messages.
-
- * tm-68k.h: Move code that is duplicated in almost every single
- m68k based machine's configuration files to this common file.
- Duplications in the configuration files still need to be removed
- (FIXME).
-
- * infrun.c (child_create_inferior): System V versions must call
- setpgrp() with no arguments, to comply with prototyping typically
- in <unistd.h>.
-
- * munch: Add support for SVR4 style nm output.
-
- * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
- file specific fields from the partial symbol table structure and
- replace them with a pointer to private data for each different
- flavor of object file reader to initialize appropriately.
-
-Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
-
- * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
- and previous.
-
- * mipsread.c (fixup_undef_type): New function. If a struct /
- union / enum is defined in a header file but nowhere else used,
- (by typedefing, pointer referencing or declaration) the mipsread code
- builds the complete tree for the structure but leaves its code as
- TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
- Guess its type based on the details of the members.
-
-Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
-
- * infrun.c (wait_for_inferior): Check return value from
- find_pc_line.
-
-Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
-
- * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
- by my last edit to this routine.
-
-Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
-
- * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
- FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
- the values before putting them into the dummy code. (From Peter
- Schauer)
-
-Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
-
- * configure.in: added ebmon target.
-

- * coredep.c (fetch_core_registers): Take new argument, use it,
- and pass it to register_addr to locate the block of registers.
- * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
-
- * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
- Sequent N_FN_SEQ like everybody else's N_FN.
-
- * main.c: Circumvent SCO cc bug with #if !!defined(USG).
- * tm-i386v.h: #endif guck.

- This avoids coredumps under `set print object on' in value_headof
- (called erroneously by value_from_vtable_info) for `p &struct'
- or `p *struct'. From Peter Schauer.
-
-Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
-
- * Makefile.in: Roll version to 4.1.2.
- * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
- size from BFD (but, FIXME, we don't yet read external nlists's and
- convert them to internal nlists's before handling them -- we still
- assume they have the same size and alignment.) Use SET_NAMESTRING
- everywhere useful.
- * exec.c (exec_file_command): Move dead coff-encapsulation code
- to BFD.
- * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

-
- * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
- vestiges of typevectors, which were for symsegs and are no longer
- used. (From a question by Eliot Dresselhaus
- <dresselh@RFT30.nas.nasa.gov>).
-
-Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
-
- * dbxread.c, coffread.c: static-ize functions that were
- gratuitiously external. (From Fred Fish.)
-
- * c-exp.y: sym->class to SYMBOL_CLASS (sym).
-
- * dbxread.c (dbx_lookup_type): Keep doubling size of typevector

- with for loops, nested if-else's and switch statements.
-
-Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
-
- * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
- between symtabs and psymtabs become ordinary error()s.
-
- * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
- properly, making "end pc" correct in shared lib psymtabs.
- (From Guy Harris <guy@auspex.com>.)
-
-Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
-
- * dbxread.c: Enable, but soften, const_vol_complaint.
- (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
- Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
- should be file-scope, not global.
- (read_struct_type): Remove ancient multiple-inheritance warning.
- (read_range_type): Check base type, complain & patch if undefined.
- * stack.c (frame_info): Demangle the function name in `info stack'.
- (From Peter Schauer)
-
-Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
-
- * eval.c (evaluate_subexp_for_address): Don't use
- TYPE_POINTER_TYPE directly (it might be zero if this type has
- never had a pointer created before); use lookup_pointer_type.
- * symtab.c (lookup_method_type): Arguments were swapped in all
- callers, so fix it here. I'm amazed this worked at all!
-
-Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
-
- * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
- "bss" rather than "data" symbols, but which still conflict.
- * m2-exp.y: Lint.

- (Reported by Mark Peek <mark@imagen.com>.)
-
- * solib.c (solib_map_sections): Relocate all sections, even
- though only the text section's size is tracked. Mark ld_text
- for eventual elimination as we generalize to N sections.
-
- * infrun.c (wait_for_inferior): Don't check if the PC is in a
- call_dummy if we were stopped by a random signal that is being
- passed to the program. This produced wierd results when calling
- functions in the inferior and signals (e.g. SIGALRM) were in use.

-
- * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and

- (VERSION): Roll version number to 4.0.95.
- (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
- New rules for building distributions. Normal distribution
- is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
- one level up from here; it calls make-proto-gdb.dir to build a
- directory `proto-gdb' which is an image of the release. The old
- `gdb.tar.Z' rule still works too.
- * config.sub, configure: Roll in latest from ..
-
-Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
-
- * doc/gdbint.texinfo: Reorder contents; reorganize new-host,

-
-Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Add Andrew Beers' changes for Modula-2 support. His ChangeLog
- entries are enclosed herein. Not all of these changes
- have been merged into the master GDB sources -- check the
- ChangeLog above here for the merge log.
-
-Mon Jun 3 17:05:45 EDT 1991
-
- m2-exp.y Created. Tested outside of GDB for a few days. Proper
- operators were added, C specific operators and tokens
- removed. yylex() revamped to some extent. Still things
- missing from the grammar, such as sets.
- Tested for two weeks in GDB v3.5.
-
-Tue Jun 11 17:23:48 EDT 1991
-
- m2-exp.y Added boolean constants TRUE and FALSE to the grammar
- so they are built-in. Sort of a hack.
-
-Fri Jun 14 12:53:51 EDT 1991
-
- m2-exp.y Added range checking for numeric constants. Any numeric
- constant is assumed to be of builtin type INTEGER unless:
- (1) it is octal or hexadecimal, in which case it is a
- CARDINAL; (2) it is too big to fit into an INTEGER, in
- which case it is a CARDINAL.
- eval.c Added simple range checking for +, -, and * on integers.
- Doesn't work very well for *, since 6 * 1,000,000,000 =
- 1,705,032,704, which fails the simple test of result >=
- first_operand, no matter in what order the operands are.
-
-Tue Jun 18 14:11:30 EDT 1991
-
- Broke the parser into parts, one containing the C grammar and the other
- containing code to be shared by all of the grammars.
-
- The following files no longer exist:
-
- expread.y
- expread.tab.c
-
- The following files were added:
-
- c-exp.y (The C grammar)
- m2-exp.y (The Modula-2 grammar)
- parser-code.c (Code that is shared by the above grammar)
- parser-code.h
- parser-defs.h
-
- Makefile.dist Changed to reflect the above dependencies. NOTE: It is
- now necessary to use the Bison compiler compiler, since it
- will generate function/variable prefixes other than yy.
-
-Tue Jun 18 16:47:49 EDT 1991
-
- symtab.[ch] Added the external variable working_lang, than holds the
- value of the current working language.
- Added the ennumerated type language_mode, with the values
- language_auto and language_manual, the former meaning that
- GDB sets working_lang as needed, and the latter meaning
- that the value of working_lang is totally under user
- control.
- symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
- REAL, BOOLEAN and CHAR. Also added the type codes
- TYPE_CODE_BOOL and TYPE_CODE_CHAR.
- utils.c Added set_language_command and show_language_command to
- implement the GDB support commands "set language" and
- "show language".
- expression.h A number of identifiers were added to the type exp_opcode
- to facilitate Modula-2 builtin functions, integer
- division, and array indexing.
-
-Wed Jun 19 13:25:58 EDT 1991
-
- language.h Added the macro STRICT_TYPE, which evaluates to non-zero
- if the language specified by working_lang requires the use
- of strict typing of expressions. Eventually, even this
- will be able to be changed by the user.
- Added the macro RANGE_CHECK, which evaluates to non-zero
- if the language specified by working_lang requires the
- checking of a value against the domain of its type.
- Eventually, even this will be able to be changed by the
- user.
- language.[ch] Predicates involving types (simple_type, ordered_type,
- same_type, integral_type, numeric_type, character_type,
- boolean_type, float_type) are added. These predicates are
- based on the current value of working_lang, and are handy
- in type-checking.
-
-Wed Jun 19 15:39:34 EDT 1991
-
- eval.c Added the function type_array_rank which computes the rank
- of an array type.
- valarith.c Added the funtion value_bool, which when given a integer
- value.h value (ie. struct value *) as an argument, it returns a
- boolean value (ie. struct value *) true if that integer
- is non-zero, and a boolean value false otherwise.
- valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
- will print out properly.
-
-Wed Jun 19 16:36:34 EDT 1991
-
- valops.c Added the function value_capitalize, which returns it
- value.h argument capitalized if its argument is a lowercase
- letter, or the argument unchanged if its argument is not a
- letter.
- valarith.c Added the function range_check_p, which returns non-zero
- value.h if its value argument is between the integral bounds upper
- and lower.
- Added the function range_check_enum_p, which makes sure
- that its value argument is a valid member of the domain of
- its type argument.
- Added the function range_check_range_p, which makes sure
- its value argument lies between the upper and lower bounds
- of its type argument, which must be a ranged type.
- Added the function check_array_index, which range and type
- checks an index of an array.
- Added the function value_multi_subscript, which computes
- array[idx1,idx2...idxN], given a value array and an array
- of values representing indicies.
- values.c Changed value_from_long to work with TYPE_CODE_CHAR and
- unpack_long to work with TYPE_CODE_BOOL and
- TYPE_CODE_CHAR.
-
-Wed Jun 19 18:04:08 EDT 1991
-
- symtab.c Stored pervasive types in a structure and make
- lookup_pervasive_type() a lookup function that was based
- on working_lang. If lookup_pervasive_type() returned
- non-zero, then that value was returned (a fix, since
- before it simply wouldn't return the pervasive type.)
- language.h Added the macro CAST_IS_CONVERSION, which evaluates to
- non-zero if the language specified by working_lang means
- "conversion" when it says "cast".
- valops.c Added the function value_real_cast(), which performs a
- value.h *cast*, not a *conversion*, which is what value_cast()
- does when it can. In particular,
- value_cast(<float_type>,4) = 4.0, while
- value_real_cast(<float_type>,4) = some mess.
- eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
- parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
- expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
- and MIN on integral types. *NOTE*: These are currently
- hardcoded to work only if there are 8 bits per storage
- unit. FIXME.
- eval.c Made logical functions call value_bool to return a
- properly typed boolean value, based on working_lang.
-
-Thu Jun 20 11:55:27 EDT 1991
-
- valprint.c Types now print out in a Modula-2 fashion. This works for
- the cases when the type is printed out step-by-step, that
- is, it doesn't work when the name of a structured type
- (which includes the keyword "struct", etc.) is simply
- displayed.
- FIXME: Perhaps this is bad. Parts of it seem to kludgey,
- since type specifications in C and Modula-2 are very
- different. The C printing of a type is very recursive,
- whereas in Modula-2 it is generally very simple. C has
- type prefixes and suffixes, which have no real analogue in
- Modula-2. Maybe type_print() should call a language
- specific type printer. This is also advantageous if we
- compile GDB to exclude some of the languages. We'll just
- leave those functions out.
-
-Thu Jun 20 16:57:10 EDT 1991
-
- dbxread.c When reading the complete symbol table in (via
- psymtab_to_symtab()), the number and types of function
- arguments are added to a function type. define_symbol()
- calls add_param_to_type() to accomplish this.
- Assumption: when we come across a function definition
- (N_FUN symbol with an 'f' or 'F' in the name), its
- arguments will appear before another function definition.
- When a function is found, a pointer to its type is placed
- in the global in_function_type. Changes that
- add_param_to_type() makes are to this global.
- valprint.c The type of a function now includes (for Modula-2) the
- types of its parameters.
- eval.c Type checking and a check for the proper number of
- arguments is now done for function calls. Not sure of the
- impact this has on C++ member function yet.
-
-Thu Jun 20 19:58:48 EDT 1991
-
- valprint.c Rewrote the type printer. Broke it into two language
- specific parts, adding the functions type_print_m2() and
- type_print_m2_1().
- An unfortunate consequence is this: if you debugging a C
- program in Modula-2 mode (why?), info types does not work
- well with regular expressions, since the types are printed
- out in Modula-2 terminology, but stored in C terminology.
- language.[ch] Added the functions new_type_last(), type_keyword(), and
- type_sep() to aid in the printing of typedefs.
- symtab.c Made the printing of typedefs as language independent as
- possible through calls to new_type_last(), type_keyword(),
- and type_sep().
-
-Fri Jun 21 11:50:26 EDT 1991
-
- dbxread.c Check all incoming ennumerated types. If it looks like
- Modula-2's BOOLEAN type, then change the type_code of the
- type to TYPE_CODE_BOOL so we can process it as a boolean
- variable.
- valprint.c Replaced some of the 0x%x with calls to sprintf and
- hexformat() in val_print().
- language.[ch] Added the function hex_to_string(), which converts its
- integral argument to a hexadecimal number (format is
- language based) and returns the result as a string.
-
-Mon Jun 24 12:25:07 EDT 1991
-
- valprint.c Some functions call type_print_1() directly, instead of
- value.h using type_print(), so they can specify where (column) to
- print things. Since type_print() takes care of language
- dependence, that needs to be called first. Added a
- parameter depth to type_print() (so it is now like
- type_print_1). Changed type_print to type_print_at, and
- made type_print a macro that passes a depth argument of
- zero.
- symmisc.c Changed all calls to type_print_1 to calls to
- type_print_at.
- Makefile.dist Made it possible to build GDB for a specific set of
- depend languages. Do this by passing a definition for the macro
- LANGS to make. LANGS should be a string containing a
- space-separated list of language names (ie. LANGS="c m2").
- The default is to build all languages. Note that grammar
- files must follow the naming convention of <lang>-exp.y.
- gdb.lang This holds the current value of the LANGS macro. It is
- examined every time make is called, and is updated if
- necessary.
- eval.c Added #ifdef _LANG_<lang> to these files.
- expread.c Still need to add them to dbxread.c and coffread.c.
- main.c
- source.c
- symtab.c
- utils.c
- valarith.c
- valprint.c
-
-Mon Jun 24 16:33:11 EDT 1991
-
- language.[ch] Added the functions hexformat_pre() and
- hex_to_string_pre(), which take a prefix argument to
- include in the format string. Thus, hexformat_pre("08") will
- return "0x08x" (if the working language is language_c).
- Made hexformat() and hex_to_string() calls to the above
- with "" as the prefix argument.
-
- am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
- dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
- infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
- mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
- pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
- stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
- valprint.c, vax-pinsn.c
-
- Changed all occurences of 0x%[0-9]*l*x in printf format strings to
- calls to hexformat() and hex_to_string(). Format strings without
- the leading "0x" were ignored.
-
- depend Updated to take the above into account.
-
-
-Tue Jun 25 15:27:18 EDT 1991
-
- symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
- and type_check_t to keep track of the current state of
- range and type checking.
- main.c Added the variables range_mode, range_check, type_mode,
- and type_check to record the current state of range and
- type checking. Added initialization code to main().
- language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
- the above variables.
-
-
-Tue Jun 25 17:57:08 EDT 1991
-
- dbxread.c process_one_symbol() updates the variable (enum language)
- source_lang based on the extension of the filename
- contained in the N_SO sybmol that started this symtab.
- When end_symtab() is called, the value of source_lang is
- put into the language field.
- stack.c select_frame() sets working_lang (and possibly type_check
- and range_check) to the language field of the symtab
- associated with the frame that is selected if working_mode
- is language_auto. If working_mode is language_manual, a
- warning is printed and working_lang is not set.
- language.c Added the function set_type_range(), which sets the value of
- type_check and range_check (if their modes call for
- automatic setting) based on the current value of
- working_lang. A non-zero argument will cause the current
- settings to be output.
-
-
-Wed Jun 26 14:51:40 EDT 1991
-
- eval.c Added range checks on assignment.
- m2-exp.y Added the grammar for sets to the language. Currently,
- these do not do anything except print an error message.
-
-Wed Jun 26 17:01:04 EDT 1991
-
- m2-exp.y Added the ability for parse_number() to parse negative
- numbers. A global flag is set upon encountering a unary
- minus. This was done to make, for example, 1 parse as a
- CARDINAL, and not as an integer, per Wirth's examples in
- Programming in Modula-2 ed.4.
- valprint.c Added support for "set radix 2" by then setting
- output_format to 't'.
- eval.c Implemented range checking on subrange types. Added calls
- to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
- Implemented MIN and MAX for ennumerated types. The
- minimum value of an ennumerated type is defined by Wirth
- as the first identifier, and the maximum as the last.
- m2-exp.y Made octal numbers ending with "B" be characters and those
- ending with "C" be numbers, per Wirth's book. (p. 34)
-
-Thu Jun 27 14:11:52 EDT 1991
-
- stack.c select_frame() now only sets working_lang, it does not
- notify the user. If working_mode is language_manual, then
- a warning is issued once.
- main.c At the end of each call to execute_command(), working_lang
- is checked against the local static (enum language)
- current. If they differ and working_mode is
- language_auto, the new settings of language, type and
- range checking are printed out.
- stack.c Modified frame_info() to include the language of the
- current frame in the output of "info frame".
- language.[ch] Added the function language_str() which returns the name
- of the current language.
-
-Fri Jun 28 15:33:14 EDT 1991
-
- m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
- the language. INCL and DECL currently cause an error,
- since sets are not implemented yet. INC and DEC are
- implemented as PREINCREMENT/PREDECREMENT with one
- argument, and as ASSIGN_MODIFY with two arguments.
- eval.c Added type checking to the above cases.
- value.h Added not_lval_constant to the lval_type ennumerated type.
- not_lval_constant means that the value is a constant
- value; that is 3 or 'a' or TRUE, not as in a constant
- identifier. This is used to help coerce numbers such as 3
- to either signed or unsigned numbers.
- valops.c Added the function value_coerce_constants() which coerces
- constant integers as following: if one is a constant and
- the other is not, the constant's type is set to the type
- of the other argument. If both are constants and one is
- signed, the other is converted to a signed constant.
-
-Sat Jun 29 17:26:29 EDT 1991
-
- valarith.c Added a better range checker. It now checks range
- (successfully) on integral operations [+-] (signed and
- unsigned) for any C sized type. Still does not work well
- for multiplication.)
- int_in_size() returns an integer that is coerced to fit into
- specified number of bytes.
-
-Mon Jul 1 13:04:14 EDT 1991
-
- language.[ch] Added the function binop_result_type(), which returns the
- builtin (struct type *) type that would be the result of a
- binop on the two values V1 and V2.
-
-Wed Jul 3 19:22:53 EDT 1991
-
- source.c Extended source_info() to include the source language in
- the output from "info source".
-
-Fri Jul 5 13:48:52 EDT 1991
-
- utils.c Moved the support functions for the GDB set/show commands
- dealing with language into language.c.
- language.c Added the function language_info(), which displays info
- about the current working language, type and range check
- settings. Called via the GDB command "info language".
- Added an initialization routine _initialize_language(),
- that sets defaults for the language, type and range
- variables and sets up the new GDB commands.
- main.c Language setup moved to language.c.
- depend Rebuilt.
-
-Mon Jul 8 10:10:22 EDT 1991
-
- valarith.c Debugged the range checker for arithmetic. Still does not
- work for multiplication very well.
-
-Mon Jul 8 12:40:37 EDT 1991
-
- language.[ch] Added the function value_true() which returns non-zero if
- its argument represents a boolean true value.
- breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
- check the truth of an expression.
-
-Thu Jul 11 12:51:34 EDT 1991
-
- language.[ch] Added the predicate structured_type(), which returns
- non-zero if the argument is a structured type.
- Added the predicate pointer_type(), which returns non-zero
- if the argument is a pointer type.
- eval.c Added the ability to do addition and substraction on
- pointers and integers. This case simply bypasses the
- type checker.
-
-Thu Jul 11 14:41:42 EDT 1991
-
- include/stab.def
- Added the symbol N_DEFD (0x4a) which is a definition
- module dependency that is used by the GNU Modula-2
- compiler and the linker. It is not important to GDB,
- except that [dbx|coff|mips]read.c should ignore these
- symbols.
-
-Fri Jul 12 16:07:00 EDT 1991
-
- valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
- 0 in val_print(). Also added statements to the else part
- to coerce type (argument to val_print) to a pointer type
- if it is an "array of unspecified length".
- valops.c Added the function value_m2_string(), which returns a
- (value) value which is a constant string, whose type is
- (ARRAY [0..n] OF CHAR). The length field of the type
- structure is set to zero, so it will be interpreted as an
- "array of unspecified length".
- stack.c Moved the language/frame mismatch check to
- main.c:execute_command().
- main.c The working language is recorded each time
- execute_command() is executed. If working lang has
- changed during its execution, then the new
- language/type/range info is printed out for the user. If
- the working language does not match the language of the
- frame, a warning is issued.
-
-Sat Jul 13 16:16:39 EDT 1991
-
- eval.c Moved all the type-checking stuff for operators to
- language.[ch] language.c. This is so we can keep language-specific
- stuff (like for what type operators are defined) in
- language.c.
- language.[ch] Added the function binop_type_check(), which checks to see
- if its two (value) arguments are type-compatible with its
- opcode argument. The opcode should represent an operation
- involving an operator. Also added the macro function
- unop_type_check, which calls binop_type_check with a
- NULL second argument.
- expprint.c Added Modula-2 operators to the op_print_tab, so info
- expression.h break works correctly. Also added "op_string", which
- returns the string corresponding to the (enum exp_opcode)
- opcode that is its argument.
-
-
-Sat Jul 13 18:26:18 EDT 1991
-
- coffread.c Added code to record the type of function arguments with
- each paricular function. Code is very similar to that
- added to dbxread.c.
- dbxread.c Moved add_param_to_type() to symtab.c
- symtab.[ch] Added function add_param_to_type() from dbxread.c
-
- *** NOTE: The above additions have not been tested.
-
-Mon Jul 15 12:50:47 EDT 1991
-
- langauge.[ch] Added the functions type_error and range_error, which work
- like error() except if the type/range mode is set to
- *_mode_warn, then they do not do a return_to_top_level(),
- but merely print a warning.
- Also changed [set|show]_[type|range]_command() to support
- the new "warn" feature.
-
-Thu Jul 18 17:50:54 EDT 1991
-
- mipsread.c Added code to record the type of function arguments with
- each particular function. Code is very similar to that
- added to dbxread.c.
-
- *** NOTE: The above additions have not been tested.
-
-Fri Jul 19 11:19:10 EDT 1991
-
- defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
- UMIN_OF_SIZE, which when given a size of a numeric type,
- return the maximum and minimum value it can hold. UMAX...
- and UMIN... return the result for unsigned types.
- symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
- struct types. They call above macros.
- dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
- avoid a name conlict with the above.
- c-exp.y Added range checking on numeric constants in
- parse_number() for completeness.
- valarith.c Made binop_user_defined_p() and unop_user_defined_p()
- return 0 if working_lang is not language_c.
-
-Thu Aug 8 14:17:22 EDT 1991
-
- main.c
- printcmd.c
- breakpoint.c Documentation strings of some commands changed to
- eliminate the references to the C language where
- appropriate.
-
-Tue Aug 13 15:48:03 EDT 1991
-
- m2-exp.y Added qualified identifiers to the grammar. The semantics
- are slightly different from those of the GDB operator ::
- c-exp.y
- m2-exp.y Added a rule to each grammar of the form: start ::= exp |
- type_exp, where type_exp is any valid type expression.
- expression.h
- eval.c Added the opcode OP_TYPE, and an error case in eval.c.
- printcmd.c Modified ptype_command() so it actually parses the input
- (necessary for type expressions with scope qualifiers).
- Added the function ptype_eval() which expects an
- expression composed of one OP_TYPE element.
- *.[ch] Replaced all occurences of parse_c_expression with
- parse_expression
- *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
-
-[End of ChangeLog entries from Andrew Beers for Modula-2 support.]
-
-Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
-
- Small fixes from Peter Schauer:
-
- * infrun.c (child_attach): Lint.
- * solib.c (find_solib): Handle shared libs version 2.
-
- Small fixes from David Wood:
-
- * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
-
- Small fixes:
-
- * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
- John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
-
- * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
- chars_per_line is at maximum (user typed `set width 0'). Fix
- from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
-
-Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
-
- * coredep.c: include ptrace.h where necessary.
- * mipsread.c(parse_lines): fix unsigned char problem that was
- messing up line numbers on SGI's and possibly other MIPS based
- platforms.
- * infrun.c (child_create_inferior): use better test to check
- return val from setpgrp().
- * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
- for sgi/irix support.
-
-Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
-
- * mipsread.c (parse_symbol): Put non-static procedures
- in the global block.
-
-Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
-
- Patch together `text_start' and `text_end' for 29K port.
-
- * exec.c (exec_command): If NEED_TEXT_START_END, define the
- variables and set them based on the exec file.
- * am29k-tdep.c: declare text_start.
- * valops.c (call_function_by_hand): declare text_end.
-
- * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
- defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
- because machines that do this will also have to know to
- set NEED_TEXT_START_END. Besides, it was a redundant way to
- say the same thing.
- * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
- CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
- NEED_TEXT_START_END.
-
-Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
-
- * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
- Pass MUNCH_DEFINE to munch whenever we run it.
- * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
- format string; use 0x%x instead.
- * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
- * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
- * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
- * inflow.c: Handle `short' process group IDs.
- * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
- and check for ptrace errors.
- * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
- (coff_symfile_init): Initialize text_bfd_scnum.
- (read_coff_symtab): Use it to find the text [and absolute?] sections.
- * ../config.sub: Add vendor nyu and os "sym[1-9]*".
- * configure.in: Add hosts rtpc-*-* and a29k-*-*.
- Merge target arm case with other "easy" cases. Add target
- cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
- Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
- process).
- * minimon.h, remote-adapt.c, remote-mm.c: Add.
- * munch: Cope with RT/PC putting fns in data segment.
- Restore ability to override `nm' by specifying MUNCH_NM.
- * xconfig/rtbsd, xconfig/ultra3: New host systems.
- * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
- and remote-adapt. Remove encapsulated coff #define's (the
- support should go in BFD, and gdb shouldn't know or care).
- * tconfig/a29k-kern: Same, but for remote kernel debugging.
- * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
- * tm-29k.h: Update BADMAG (though it should go away).
- Allow the register definitions to be overridden in another
- tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
- RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
- DUMMY_SAVE_GR96, for handling kernel calling conventions
- that use GR64+ rather than GR96+.
- * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
- remote debugging of Ultra3 kernel. Includes tm-29k.h and
- overrides various things.
-
- * remote-mm.c (mm_attach, mm_wait): Handle attach like
- child_attach does, making a clean stop in the newly attached
- program.
- * remote-eb.c: Lint.
-
- * coffread.c: Make coffread independent of any particular
- variant of COFF. Avoid #include-ing any particular one except
- internalcoff.h. BFD now passes key values for symbol reading
- as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
- and the symbol masks and shifts); use them.
- Remove obsolete end_of_text_addr.
-
- * exec.c: Remove unused include files.
-
-Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)

- its level number, by calling print_stack_frame.
- * frame.h: Add selected_frame_level, print_stack_frame.
- * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
- * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
- Change print_sel_frame and print_selected_frame callers to
- print_stack_frame.
-
- * dbxread.c (read_ofile_symtab): Avoid empty else clause.
- * symfile.c (free_named_symtabs): Ditto.

- systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
- * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
-
- * utils.c (error): if error_pre_print is set, print the string
- first.
- * main.c (main, print_gnu_advertisement, print_gdb_version):
- Reformat legalese so it always prints, but acts as an "I'm here"
- message while symbols are being read. If any errors occur,
- print a few newlines to set off the message and start it at the
- left margin. Remove mention of "help" command, and don't yak
- about symbol reading.
- (catch_errors): Error string is now printed first in case of
- error, not last.
- * command.c (undef_cmd_error, lookup_cmd): On undefined command,
- suggest the "help" command.
-
- * Makefile.in (VERSION): Set to 4.0.2.
-
-Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * .gdbinit: Remove useless "rr" command. Set complaints
- to 1 for people debugging gdb.
-
- * breakpoint.c, remote-vx.c: Reword strings printed by
- catch_errors callers.
-
-Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * WHATS.NEW: "history write -> history save". Doc "write on/off".
- (Fix from kenc@viewlogic.com.)
-
- Fix some infrastructure to be able to cope with host and target
- machines with different sized basic types (ints, ptrs, etc).
- (Idea from pierre@la.tce.com (Pierre Willard).)
-
- * values.c (value_from_longest): Rename from value_from_long.
- Handle pointer types as well as integers, so that targets with
- different pointer sizes from the host can be accomodated.
- * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
- valarith.c, valops.c, valprint.c, value.h, values.c: Rename
- uses of value_from_long to value_from_longest.
- * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
- the correct pointer type to value_from_long{est}.
-
- * doc/gdb.texinfo ($_, $__): Describe types of these variables.
-
- * remote-vx.c: Remove obsolete code for calling functions via
- vxworks kludge interface (it referenced value_from_long).
-
- * valops.c (value_string): Find malloc with lookup_misc_func, not
- raw search.
-
-Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Make writing to files work properly. (Fixes to BFD are also needed.)
-
- * core.c (core_open): Open file ourselves, read or r/w, depending on
- write_files. Use bfd_fdopenr.
- * gdbcore.h (write_files): New variable.
- * exec.c (write_files): Define variable, add set&show for it.
- (exec_file_command): Use write_files to open for read or r/write.
-
- Make shared library reading happen automatically. These changes
- are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
-
- * inferior.h (stop_soon_quietly): Add to exported variables.
- * infrun.c (child_create_inferior): call solib hook, if defined.
- (child_attach): call solib hook, if defined.
- * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
- (find_solib): Use lookup_misc_func rather than hand-rolled.
- (symbol_add_stub): New stub for catch_errors.
- (solib_add): Avoid output if !from_tty. Catch errors rather
- than just calling symbol_file_add and bombing.
- (solib_create_inferior_hook): Interface with the target process
- to let it read and alloc shared libs, then figure out what it did.
-
- * core.c (validate_files): Fix typo, soften warning.
- (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
-
- * utils.c (fputs_demangled): Avoid duplicate printing if
- demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
-
- * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
- (Fix from pierre@la.tce.com (Pierre Willard).)
-
- * main.c (catch_errors): Change argument to a char * from an int,
- since a char * can point to a struct full of glop, but an int
- is not guaranteed to be able to hold a pointer.
- * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
- breakpoint_re_set_one, breakpoint_re_set): Adapt.
- * core.c (core_open, solib_add_stub): Adapt.

-
-Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
- * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
- tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
- to single structures rather than arrays; when passing
- their address, use &. This avoids trouble with bdead compilers.
- * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
- instead. This avoids portability headaches.
- * mips-tdep.c (mips_do_registers_info): Only print FP regs if
- asked to.
- * source.c (open_source_file): Avoid ANSI const bdeath by
- skipping declaration and then casting result value.
- * tm-hp300bsd.h: Clarify comment.
- * utils.c (strstr): Result is const char *; ANSI bdeath.
- * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
- since system include file defines it differently from "defs.h",
- though the two are equivalent for our purposes.
- * tconfig/hp300bsd: Add m68k-tdep.o.
-
-Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * tconfig/sun*4: Remove warnings about system assembler.
-
-Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * mcheck.c: Avoid warning about undeclared abort fn.
- * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
- it causes recursive calls to error() when used in cleanups.
- To do so requires that we make it a function, so we do.
- * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
- * utils.c (do_cleanups): Remove the current cleanup from the
- chain *before* calling it, in case error() is called from it.
- The result won't be pretty, but won't be an infinite loop either.
-
-Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
-
- * dbxread.c (read_struct_type): Grok anon structs for C++.
- (vb_name, vptr_name): Null terminate these strings.
-
-Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Minor bug fixes from BSD Net2 gdb:
-
- * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
- returns 0, there is no previous frame.
- * breakpoint.c (commands_command): If !from_tty, don't call
- input_from_terminal_p().
- * dbxread.c (record_misc_function): Speed up slightly.
- (compare_psymbols): Ditto.
- * infcmd.c (do_registers_info): Take a second argument to
- determine whether to print float registers. "info registers"
- does not do so anymore. "info all-registers" does, now.
- * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
- arg and ignore it.
- * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
- * inflow.c (initialize_inflow): Set tflags_ours correctly.
-
- Other fixes:
-
- * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
- executing_breakpoint_commands if we are interrupted by error.
- * coffread.c (init_lineno): Avoid problem with zero-sized linetab
- versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
- * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
- catch_errors() so we can setup the frame regardless of whether
- the shared libs work.
- * ieee-float.c (double_to_ieee_extended): Get exponent from
- right place in little-endian systems. From John Carey.
-
-Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * main.c: Remove unused terminating_signals and catch_termination().
- (long_options): Terminate with a zero element.
- [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
- (gdb_readline): Make call-compatible with readline.
- (init_signals): Improve comments re vfork vs. signal.
-
- * utils.c (prompt_for_continue): Use new gdb_readline().
- If we prompt for continuation, we don't let CR repeat the previous
- command, once we get back to a prompt. It's too easy to keep
- hitting CR, expecting "--more--" prompts, and have some long
- command start repeating on you.
-
-Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * blockframe.c (frameless_look_for_prologue): Speed up by
- calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
- * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
- Define two variants, one faster.
- * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
- and return zero, rather than giving an error.
- (setup_arbitrary_frame): Initialize the PC in the new frame.
- (skip_prologue): Add a second arg saying whether we're just
- checking for a frameless function or not.
-
- * core.c (core_open, core_close, core_xfer_memory): Move
- section table pointers and bfd* into the target_ops.
- (core_open): Allow errors in shared lib reading, etc.
- (core_files_info): Describe shared library sections.
-
- * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
- exec_files_info, set_section_command): Move section table
- pointers and bfd* into the target_ops.
- (add_to_section_table): Add BFD to section table.
-
- * target.c (target_xfer_memory, target_info): Pass target to
- xfer_memory and target_info functions.
- * target.h: ''
-
- * gdbcore.h: Move struct section_table.
- * target.h: New home of struct section_table.
-
- * solib.c (solib_add): New argument is the target_ops whose
- section list is to be added to, if any. Reallocate the
- sections in that target to add any that come from shared libs.
- (throughout) so_sections renamed to sections.
- (solib_xfer_memory): Deleted.
- * tm-sunos.h (SOLIB_ADD): Add target argument.
- (SOLIB_XFER_MEMORY): Delete.
-
- * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
- remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
- from target_ops. It's the same on all targets. Add two section
- pointers to target_ops.
-
- * stack.c (find_relative_frame): Dump ancient algorithm for
- "down", just use handy "next" pointers.
- (frame_command): Don't error if there is no stack; let user
- set one.
-
- * inflow.c (new_tty_prefork, new_tty): New prefork routine
- modifies static state in the parent process; new_tty itself
- runs in the child and modifies the child's file descriptors
- to match the saved static state.
- * infrun.c (child_create_inferior): Call new_tty_prefork,
- fork, then new_tty.
-
- * infptrace.c (child_xfer_memory): Add ignored target arg.
- * remote-eb.c (eb_xfer_inferior_memory): ''
- * remote-nindy.c (nindy_xfer_inferior_memory): ''
- * remote-vx.c (vx_xfer_memory): ''
- * remote.c (remote_xfer_memory): ''. Rename from
- remote_xfer_inferior_memory.
-
- * main.c (main): Only try to attach "corefile" argument if
- it starts with a digit.
-
- * symfile.c (symbol_reloading): New "set/show" variable.
- (symbol_file_add): Shorten message about symbol reading.
- (add_symbol_file_command): Merge with add_syms_addr_command,
- since this should work on all targets now.
- (stop_whining): Default to zero, to shut up complaints
- about bad symbol tables on many systems.
- (free_named_symtabs): Just exit unless symbol_reloading.
-
- * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
- and add comment explaining shared library screw.
-
- * source.c: #if defined => #ifdef.
-
-Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * doc/gdbint.texinfo: Improve doc on porting to new OS's.
-
-Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * doc/rdl-apps.texinfo: provide default readline-appendix finder
- (doc/Makefile knows how to make one for local config)
-
- * Makefile.in: use doc/Makefile for doc targets
-
- * doc/Makefile: GDB documentation now has its own Makefile
- doc/refcard.tex: renamed from "gdbrc.tex"
- doc/.Sanitize: add Makefile; recognize renamed refcard.tex
- doc/gdbint.texinfo: add markup in "Cleanups" chapter
-
-
-Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * values.c (baseclass_addr): When reading target memory, use the
- length of the basetype, not the upper type. We've only malloc'd
- enough space for the basetype, leading to errors in free().
-
- * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
- ends up as a function specially, since we know the actual type of
- the pointed-to address. This (somewhat) fixes display of
- expressions that include misc_function_vector names. Try `cond 1
- !strcmp("a","b")' then `i b'.
-
- * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
- The child can be proceeded from inside wait_for_inferior in
- evaluating breakpoint conditions, and DO_DEFERRED_STORES was
- getting skipped in that case.
-
- * expprint.c (print_subexp): Use filtered output, since the
- subroutines we call use it, otherwise the output is horribly
- mangled, since output of wrappable stuff comes out late.
-
- * Makefile.in: Bump VERSION to 3.98.1
-
- * infrun.c (child_create_process): Use execlp to find the
- shell to exec our target program. This requires some fiddling
- with `environ' since there is no execlpe().
-
-Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
-
- * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
- Minor rearrangement of refcard permits two new make targets--
- gdbrc.dvi DVI output for refcard, using CM fonts
- gdbrc.ps PostScript refcard, using PS fonts
-
-Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * GDB-3.98 release.
-
- * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
- * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
-
-Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * doc/gdb.texinfo: last changes for release.
- Minor typo and formatting fixes; incorporated most fixes remaining from
- filed mail commenting on earlier drafts.
-
- Added warnings: pipes don't work in run command;
- conditions are converse of assertions;
- step over fn without debug info goes to next fn;
- vars may have "wrong" values near fn entrance, exit
-
- Added example from Kingston on printing repeated nonadjacent values
-
- Added explicit mention that in Emacs gdb mode C-c and C-z are like
- shell mode for signals
-
- Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
- doesn't sound so much like its parent "Stopping and Continuing"; also
- moved entries on continue to top of section, so they don't get lost.
-
- Improved installation directions in appendix, added manual formatting
- instructions
-
-Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * configure.in: Remove xm.h and tm.h even if we aren't linking
- new ones, so "./configure sun4; ./configure none" does the right
- thing. Assume that alldeps.mak and depend are already built in
- srcdir, and avoid running "make" (particularly "make depend",
- which involves "gcc") from inside configure. Build Makefile
- directly rather than building Makefile.conf first.
- * configure: Regenerate with above changes.
- * Makefile.in: Use $(BISON) to find bison. Roll VERSION
- to 3.98. Revise gdb.tar.Z procedure to produce a file
- called gdb-$(VERSION).tar.Z but which unpacks into a
- directory called "gdb". Move non-source files out of
- $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
- (depend): Don't try to do "gcc expread.y".
- (expread.o): Update dependencies by hand.
-
-Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * doc/gdb.texinfo:
- Fixed a variety of small typos that prevented info from formatting
- cleanly; altered too-long heading for GPL Appendix, as discussed
- w/RMS; Changed date on cover to July 91.
-
-Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * doc/gdb.texinfo:
- (1) Applied some fixes due to comments from Larry Breed (easier ones
- through chapsec 5.2)
- (2) Eliminated use of @footnote---had my doubts about it anyways, and
- it's broken in latest texinfo
- (3) Introduced *some* use of [] for optional arguments, where
- explanation is not simpler by listing cmd w arg and cmd w/out arg
- separately. Still not using @deffn.
- (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
- couple of headings are too long. Need patches to texinfo or revision
- to GPL-2.
-
- * Partial update to README (which still needs work for this
- release!): (1) use of configure corrected for new script,
- (2) "make gdb.dvi" and "make gdb.info" mentioned.
-
-Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * symtab.c (lookup_symbol): Don't complain right off about
- no debug symbols; use the misc function vector first.
- (list_symbols): Use misc function vector to find symbols
- that don't have debug info, and print them.
- (find_pc_symtab): Temporarily avoid fatal() when psymtab
- PC range doesn't match symtab PC range, as it does on the
- MIPS because our symtab reading isn't perfect.
-
- * dbxread.c (dbx_symfile_read): Make warning about
- "no debug symbols" slightly nicer.
-
- * source.c (select_source_symtab): If "main" symbol exists,
- but decode_line_spec can't find line info, don't just return
- a zero; try other source symtabs or give an error.
-
- * mipsread.c (parse_partial_symbols): Sort the psymtabs by
- their low addresses first, then rip through fixing high addrs.
-
- * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
- <runene@ifi.uio.no>.
- (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
-
-Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * Minor, mostly mechanical, cleanup of doc subdir for clean
- makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
- and gdb.info (post- texinfo2 makeinfo) generated for distribution.
-
-Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Mostly MIPS and general symbol-reading fixups.
-
- * doc/gdbint.texinfo: Add documentation on symbol-reading
- interface.
-
- * mipsread.c: Remove kludges around #include "ecoff.h".
- Remove redefinitions of a_magic, etc, no longer used.
- (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
- Fix global overview comments to match symfile.c protocol.
- (mipscoff_new_init): Eliminate cur_hdr if we have one.
- (mipscoff_symfile_read): Eliminate unused code. Avoid
- sorting all the symtabs, when all we have read here is psymtabs.
- The symtabs are sorted as they are created anyway. Tell
- condense_misc_bunches whether we're mainline.
- (psymtab_to_symtab_1): Pass filename when recursing, to make
- stack trace more informative.
- (parse_partial_symbols): Assume cur_hdr as argument.
- (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
- Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
- the TYPE_NAME of char *, since that's done in symfile.c.
- (free_numargs, parse_symbol, add_symbol, add_block,
- shrink_linetable): Declare these fns void.
- (upgrade_type): Convert tree of if's to switch. Clean up
- bogus "off == 0" handling with a complaint. Avoid setting
- field bitpos and bitsize of array with lower and upper bounds.
- Check specified bitsize of elements against their actual type's
- bitsize, and complain if different. Complain about unknown
- type qualifiers.
- (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
- (psymtab_to_symtab_1): Print names of subsidiary files that
- are being read in. FIXME, we read far too many files. This code
- is not the problem, the problem is in parse_fdr where the psymtabs
- are set up.
- (cross_ref): Result should indicate that we used one aux entry
- normally, or two if we encountered a "next" entry. This used
- to leave the caller pointing at the wrong aux entry.
- (add_symbol): If overflowed cur_block, reallocate it larger,
- chase all pointers to it, and complain(), rather than clobber memory.
- (shrink_block): Use xrealloc rather than xmalloc-and-copy.
- (new_field): Only allocate one field initially, not two.
- Pull ++ out of macro argument. Simplify.
- (_initialize_mipsread): Avoid initialization of importd
- global_psymbols and static_psymbols.
-
- * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
- to properly set pst->symtab; avoid searching for it.
- (symfile_fns): Improve comments, add a FIXME.
- * dbxread.c: Update comments to reflect symfile protocol.
- (read_ofile_symtab, end_symtab): Return the symtab.
- (psymtab_to_symtab_1): Set pst->symtab.
-
- * coffread.c (coff_symfile_read): tell condense_misc_bunches
- whether we're mainline.
-
- * symfile.h (sym_fns): Remove unused sym_discard member.
- * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
-
- * mtrace.c (mtrace): Take effect if mallwatch is set, even if
- the environment variable is not.
- * infcmd.c (finish_command): Use filtered printfs.
- * cplus-dem.c: Add struct tags to a few unnamed structs.
- * valops.c (value_coerce_array): Improve comments.
- * valprint.c (type_print_varspec_suffix): Print array size only
- if greater than zero.
- * m88k-tdep.c: Shift some lines left by one space, that had
- apparently been trashed at some point.
- * TODO: More things to do, a few got done.
-
-Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
- (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
- comments.
- * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
- * expread.y, findvar.c, symmisc.c: Ditto.
- * printcmd.c (address_info): Update printed forms of LOC_
- symbols. Elim LOC_EXTERNAL.
- (print_frame_args): Keep track of param stack offsets before
- re-looking up to find the local register param is kept in.
-
- * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
- Further integration of mipsread into gdb. Eliminate unused
- routines, duplicate declarations. Handle static symbols in
- psymtabs as well as external symbols. When reading symtabs,
- insert symbols into the correct block (global, static, or a local
- block).
- (read_mips_symtab, parse_partial_symbols): Don't pass useless
- "incremental" arg.
- (mipscoff_symfile_read): Don't call select_source_symtab.
- (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
- rather than SYMBOL_VALUE.
- (parse_external): Comment clobbering of top_stack.
- (parse_partial_symbols): Update comments. Allocate and parse
- static symbols as well as external symbols. FIXME, enum values
- are not handled in this pass, but should be. Inline new_psymbol.
- Use SYMBOL_VALUE_ADDRESS.
- (psymtab_to_symtab_1): Read symbols into global static block
- by default (until enter some function's local block context).
- (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
- (destroy_all_symtabs, new_psymbol): Eliminate, unused.
-
- * source.c (select_source_symtab): Select a source symtab
- from either the symtabs or, failing that, the psymtabs.
- (list_command): Update error message.
- (forward_search_command, reverse_search_command): Use getc, not
- fgetc, for speed. FIXME, add comment about buffers that die if
- overrun by long line.
-
- * values.c (unpack_field_as_long, modify_field): Avoid shifting
- by an entire word, which is not portable, if we have a 32-bit
- field. (Code in dbxread.c already turns such bitfields, if
- aligned, into ordinary ints, but fixing this will help for other
- symbol formats and for future changes.)
- * core.c (core_open): Handle ANSI const brain death.
- * utils.c (vprintf): Fix varargs typo.
-
-Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * findvar.c (find_var_value): Handle &function better.
- * TODO: Document work needed on &fn and &array.
- * printcmd.c (print_address_symbolic): New arg is the prefix
- to print if a name is printed.
- (print_address_demangle): Honor "set print address" now.
- Use new arg above to improve spacing of output.
- * valprint.c (val_print): When printing function pointers,
- print symbolic form too.
- * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
-
-Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * core.c (memory_error): Reword error msg to mislead less.
-
- * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
-
- * mipsread.c (read_mips_symtab, read_the_mips_symtab,
- parse_partial_symbols): Use newer BFD internals (external_filehdr
- and external_aouthdr), byte-swap the fields that we care about
- before using them, and make the file header data local to
- read_the_mips_symtab rather than global.
-
-Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
- from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
-
- * main.c (command_line_input): Flush stdout and stderr
- before every call to readline. This reportedly fixes a bug
- that comes up in Sys V running emacs-gdb and/or xxgdb,
- when stdin/out are pipes or sockets.
-
-Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
- Avoid declaring Makefile dependencies, because GNU Make stupidly
- tries to update it if we do.
-
- * coffread.c: Revise for minor changes to bfd internal coff
- indexes.
-
- * configure: If -template= is given a relative path, make it
- absolute before recurring in subdirectories.
-
- * configure, configure.in, Makefile.in: Install "configure" script
- as replacement for config.gdb.
- * config.gdb, Makefile.dist, Makefile.sdir: Remove
- * README: Update for configure, mostly. FIXME.
-
- * Add dec3100 as equivalent to littlemips. Indicate in all host &
- target config files that they are for the host. When the lines
- get copied into the Makefile, this makes it more obvious what's
- up.
-
-Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * sparc-opcode.h (trap opcodes): Avoid leading spaces or
- tabs, which end up in the disassembler output inadvertently.
-
-Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Make it compile cleanly in an ANSI GCC2 environment.
-
- * blockframe.c: <stdio.h>
- * cplus-dem.c: free takes a void *, ifdef __STDC__
- * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
- LONG_MAX/radix.
- * defs.h (alloca): Avoid doing anything if alloca already def'd.
- * stddef.h, stdlib.h: Remove these files.
- * symtab.c: Avoid declaring qsort, close.
- * symfile.c: Avoid declaring close.
- * utils.c (vprintf): Declare "ap" arg as proper va_alist.
- * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
-
- Assorted other changes.
- * dbxread.c: include "libaout.h", not "liba.out.h".
- * printcmd.c (print_frame_args): Set recurse properly for
- indentation of struct and array parameters.
- * valops.c (value_cast): Allow cast to void.
- * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
- single_step() in a target-independent fashion.
- * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
- set up to be ready to continue. This makes us target independent.
- * infptrace.c (child_resume): Remove call to single_step; now
- can single step a SPARC target of any kind.
-
-Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
-
- * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
- docn into separate sections---basically chapters, plus two loose
- pieces that can be configured to go in different places. This
- allows GNU m4 to preprocess the manual without coredumping.
-
- * Makefile.dist: tell TeX where to find texinfo.
-
-Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
-
- * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
- the new target "rdl-apps.texinfo" which captures the Makefile
- variable that records where to find the Readline libraries.
-
-Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
- * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
- * defs.h (const, volatile): Only define if not already defined.
- * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
-
- * README: Update for release 3.95.
- * config.gdb: Don't create readline dir in subdir builds.
- * main.c: Include with "..." form for non-system include files,
- so "gcc -MM" for "make depend" works.
- Include readline files with "...h" rather than <readline/...h>.
- * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
-
- * coffread.c: Undo minor damage done by Rich Pixley. Use
- different internal and external representations of COFF
- data structures. Use new BFD routines for swapping them in and
- out.
- * symfile.c (free_named_symtabs): Avoid freeing file names that
- are null or empty. Old i960 tools seem to produce files that
- claim to have empty names, causing each successive file read
- to blow away the previous one.
- * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
- Move deferred_stores to top of file, but don't separate its
- #define's from its variable. Add commentary.
- * Makefile.dist: Fix Rich damage; undo "configure" changes in
- favor of keeping the (working) config.gdb. Move readline
- library up a notch.
-
-Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
-
- * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
- debug info.
- * infptrace.c (fetch_registers): no result, since now void.
- * tconfig/news: target depends on m68k-tdep too.
-
-Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
-
- * Makefile.dist: added readline/inc-*.texinfo to dependencies for
- gdb.dvi target
-
- * readline/inc-history.texinfo, readline/inc-readline.texinfo:
- applied various small fixes due to or inspired by RMS comments
-
- * doc/gdb.texinfo: finished using all RMS comments, save those for
- appendices on readline and cmd history (which are in other source
- files)
-
-Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
-
- * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
- chapter 9; (2) documented 'break' command's menu mode for
- overloaded names, in response to hgs problem report C++ p-31
-
-Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)

- cleanups to first three nodes; (3) new "Contributors" node;
- (4) Appendix, Renamed Commands; (5) divert specialized startup
- instructions to "Targets" chapter for generic manuals, while
- leaving them up front for manuals specific to specialized
- environments; (6) apply fixes from RMS comments through chapter 4.

-
- * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor

- config.gdb none
- before checkin
-
- * gdbint.texinfo: added instructions on generating gdb.info* files
- locally for release. These are ordinary info
- files, formatted from gdb.texinfo (via gdb-all.texinfo, see
- Makefile)---but due to use of texinfo 2, can't count on makeinfo
- to generate these, so we distribute them already formatted.
-
- * gdb.texinfo: included full Info node and menu crud (as generated
- by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
-
- * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
- put in comments-for-future gdb.info target (one day makeinfo will
- work again).

- print object.
- Also covered all recent GDB command renames for v4.

-
-Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Permit symbols to be superseded when new symbol files have
- been read in, particularly for VxWorks.
-
- * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
- to the main file, as well as to include files. Also, put global
- functions into the global psymtab, to make "i fun" work.
- (end_psymtab): Free named symtabs and psymtabs for a file, once a
- new psymtab for it has been read.
- * coffread.c (end_psymtab): Free named symtabs and psymtabs for
- a file, once a new symtab has been read for it.
- * mipsread.c: FIXME. We need to do the same for MIPS, but it
- looks harder to determine the top-level block before it's been
- queued to the psymtab list.
-
- * symfile.c (symbol_file_add): Use filtered printing and wrap it.
- If we have wiped out any old symbol tables, clean up at end of
- symbol reading.
- (symbol_file_command): Don't reference symfile_fns if it's zero.
-
- * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
- defines for the blocks of a blockvector that contain global and
- file-static symbols and the first of the smaller scope contours.

- (_initialize_symtab): Restore "info types".
-
-Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * m68k-stub.c: Remote stub for 680x0's, created from
- rem-m68k.shar (which is removed).
- * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
- Remove RCS log stuff now that we use CVS and it blows our diffs.
-
-Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * symmisc.c (free_named_symtab): Make it work, in its current

- free_named_symtab and print warning if we blew user's state.
- * symfile.h: free_named_symtab now returns an int.
-
-Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
- is the first symbol read, even if not mainline.
- (dbx_psymtab_to_symtab): symfile might be zero, cope.
- * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
- (set_section_command): New command ("section xxx yyy" -- should
- be renamed to "set section xxx yyy" FIXME) which sets the
- base address of a section of the exec file, overriding the
- virtual address that BFD reports.
-
-Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * exec.c: Add add_syms_addr_command to exec_ops, so you can
- load symbols at any address while examining an exec file.
-
-Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
- for printing the float info is host-dependent, not
- target-dependent. FIXME.
- * i386-pinsn.c: Move #includes to top, remove useless ones.
- * i386-tdep.c: Don't bother including <.../reg.h> since we
- don't use it (and it doesn't exist on host systems).
-
- * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
- Convert negative numbers properly.
- (ieee_test): Make numbers really random; fix format arg.
-
- * infcmd.c (attach_command, detach_command): Don't repeat on CR.
- * core.c (core_detach): Unpush core_ops, which might not be on
- top. We used to just pop the top, which broke things. Don't
- need dont_repeat() any more.
- (core_file_command): Psst! Don't repeat it.
- * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
- * expprint.c (print_subexp): Avoid switch fallthru on
- BINOP_ASSIGN_MODIFY, so we can print += and such.
- * frame.h: Fix typo.
- * inflow.c (kill_command): After killing inferior, print our
- current frame in the core file, if we have one.
- (generic_mourn_inferior): When inferior dies, either select
- the current frame (in the new target, e.g. core file), or
- set both the current and selected frames to NULL.
-
- Changes from Peter Schauer.
-
- * infptrace.c: Avoid <sys/ptrace.h> on USG.
-
- * Make all file names fit in 14 characters (sigh and damn!):
- mv hp300hpux-xdep.c hp300ux-xdep.c
- mv symmetry-xdep.c symm-xdep.c
- mv symmetry-tdep.c symm-tdep.c

- * Makefile.dist, README, config.gdb, convex-pinsn.c,
- tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
- xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
- names.
-
- * command.c (user_info_1, user_info): New command for listing
- the user-defined commands.
-
-Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * dbxread.c (really_free_pendings): Clear file_symbols
- and global_symbols after freeing them; otherwise, running
- this function twice (if it appears twice on the cleanup
- chain), we try to free things twice.
-
- * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
- based on text_addr (the address of text in core), not on addr (the
- offset between text in the .o file and in core). This change
- is from Peter Schauer.
-
- * main.c: Define ALL_CLEANUPS as a cast of zero.
- (return_to_top_level): Use it.
- (main): Do all cleanups after each command run as part
- of the gdb startup sequence. Also do all cleanups before
- entering the command loop, and every time we exit the command
- loop and reenter. Before, the cleanups from the startup sequence
- were being left undone until the first error!
- (command_loop): Rename do_nothing cleanup to command_loop_marker
- so we can see it easily when examining the cleanup chain.
- (init_signals): Add another do_nothing for signal handling.
- (quit_command): Only try to kill target if it has execution.
- Problems in the target stack got us into a state where
- inferior_pid was nonzero but none of the targets had execution.
- In this state you couldn't exit gdb.
-
- * dbxread.c: Two changes from Peter Schauer.
- (echo_command): Fflush output after an echo command.
- (show_history): Pass all args to cmd_show_list.
-
- * utils.c (init_malloc): Call mtrace to turn on tracing
- if the environment variable MALLOC_TRACE is set to a file name.
- * mtrace.c: Add source file which provides a log of every malloc,
- free, and realloc to a trace file.
- * mtrace.awk: Add source file which analyzes the trace file.
- * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
- (VERSION): Roll to 3.94.3.
-
- * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
- (check_duplicates): Don't bother with watchpoints.
- (set_raw_breakpoint): Comment about danger of this routine.
- (watch_command): Parse and eval all args before calling
- set_raw_breakpoint.
-
- * solib.c (find_solib): Avoid error in referencing memory to
- see if any more shared libraries have been added. This is
- particularly useful if the target has terminated. Bug reported
- by Peter Schauer.
-
- Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
- in bringing up 3.94.2 on the Sun-3.
-
- * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
- * breakpoint.c (enable_breakpoint): Check for valid watchpoint
- expression (in scope) before reenabling watchpoint.
- * signame.c (init_sigs): Add missing declaration of i, fix
- sys_siglist declaration.
- * source.c (list_command): Fixed range computation to use
- lines_to_list ().
- * stack.c (backtrace_command): Do not allow command if target has
- no stack, print informative error message.
- * target.c (target_command): Do not write into command line
- because this fails if the target command is used in a user defined
- command. [This change was enhanced by gnu to support any-
- unique-prefix matching on target names.]
- * valops.c (value_struct_elt): Avoid infinite loop on an
- erroneous attempt to print the member of function (try p main.p).
-
-Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * expread.y (name_no_typename): Avoid reduce/reduce errors
- caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
- Since the GDB parser really doesn't use name_no_typename in a
- name-only context, the parser can't tell the diff between
- names and numbers here. Avoid allowing a name_no_typename
- to be a NAME_OR_*INT to resolve the conflict.
-
-Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
-
- * valprint.c (val_print_fields): bitfield printing didn't handle
- byte order. Indirect through a few more fns to cope.
-
- * values.c (modify_field): also cope with byte order.
-
-Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Cleanup for release 3.94.2:
-
- * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
- include files. Roll version to 3.94.2.
-
- * coffread.c (init_stringtab): Read length into unsigned char
- array before swapping; don't assume 32-bit longs.
-
- * target.c (target_info): Don't bother with get_sym_file, just use
- the symfile global variable.
- * symtab.h, symfile.c (get_sym_file): Delete it.
-
- * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
- (define_symbol): Set symbol line number to 0 if not gcc-compiled.
- (read_type): Replace one more error() with complain().
-
- * mipsread.c (parse_partial_symbols): Replace printf with complain.
-
- * i960-tdep.c: Fix copyright attribution.
-
- * config.gdb: Quote all backquotes in doublequotes. You can
- quote me on that. BSD 4.4 shell found this one.
-
- * infptrace.c (throughout): The third argument to ptrace is an
- int *, not an int.
-
- * infrun.c (wait_for_inferior): When program has terminated, we
- have to call target_terminal_ours before we pop that target off
- the stack (e.g. before a call to target_kill or
- target_mourn_inferior). This fixes problem where a program
- terminates, then GDB stops for (tty output) and you have to type
- "fg" to the shell to resume it. FIXME: This code for what to
- do after termination really should be in normal_stop instead.
-
- * gdbcore.h (read_memory_check): Change declaration; it changed
- names months ago.
-
- * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
- 4.4 prereleases, this avoids a bug in their sgtty compatability
- support.
- * remote.c: Use terminal.h rather than hand-rolling the same.
-
- * signame.c, signame.h (psignal): Arg is unsigned, not int.
- * utils.c (strsave, strstr): Fix arg types.
- * valprint.c (val_print): lint
-
- MIPS symbol table support from Per Bothner:
-
- * symfile.c (symtab_fns): Remove initializer table that needs to
- be hacked for each new symbol file format supported.
- (add_symtab_fns): New function, chains symbol table
- handlers into the global list.
- (symfile_init): Search this list.
- * symfile.h: Add next pointer, declare add_symtab_fns.
- * coffread.c (_initialize_coffread): Call add_symtab_fns.
- * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
-
- * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
- symbol *). Thus, we no longer need the hack to trash
- pst->filename. Good, since that hack confused code in symfile.c!
-
- (reorder_symtabs, destroy_all_symtabs): Removed static
- all_symtabs, which was used to qsort symtabs in reorder_symtabs.
- Instead, the latter now uses a temporary array (stack-allocated
- from an obstack, and then freed).
-
- (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
- haven't been set in the outermost stBlock of a procedure. This was
- a problem with f77 binaries on Ultrix 4.?.
-
- (new_symtab, new_symbol, new_type): Continue changing code to use
- obstacks more and otherwise conform to dbxread internal style.
- Made the free_code of symtabs be free_linetable (as in dbxread)
- instead of free_contents. This implies memory leaks when reading
- a new symbol table, until the conversion is finished. Did change
- (struct symbol) and (struct type) to be allocated on the
- symbol_obstack. Blocks and blockvectors are among the things
- still "leaking."
-
- * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
- tested much, but it solved one problem (reported by Meissner), and
- cleans up some other things. The problem happened when an
- included file contains actual code (functions) and not just
- definitions. The mips coff is a little inconvenient there, since
- it may cause a procedure to be mapped to the wrong psymtab.
-
- * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
- * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
- this will need work for the new core paradigm.
-
- Opcode patches from the net:
-
- * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
- ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
- missing altogether - they are added here. From Bruce Bauman.
- * mips-opcode.h: The low mask for C0 instructions was too small.
- From Garrett Lau. I modified the fix to check the entire 32-bit
- opcode.
-
- * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
- Bauman.
-
-Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
-
- * dbxread.c (read_type): Pointer subtraction (value_sub in
- valarith.c) sometimes failed because the types of the
- pointers being subtracted were not identical.
- These differed because dbxread.c was allocating pointer types
- using dbx_alloc_type+smash_to_pointer_type instead of
- lookup_pointer_type. I failed to find a justification for the
- former, so I changed it to use the latter. Similarly, I
- replaced smash_to_function_type by lookup_function_type,
- and smash_to_reference_type by lookup_reference_type.
-
- * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
- _initialize_mipsread): corresponding changes.
-
- * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
-
- * source.c (mod_path): Do tilde_expand on each component of the path,
- rather than on the (list of) paths as a whole.
- (print_source_lines): Set first_line_listed in addition to
- current_source_symtab and current_source_line. If the source was
- not findable, after a "dir" command to fix the problem,
- a "list" would get the wrong lines.
-
- While I was there... (gnu):
-
- * dbxread.c (read_type): Change error to complaint.
-
-Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- First attempt at detailed understanding of symbol table memory alloc.
-
- * dbxread.c (dbx_symfile_read): Free our string table if we
- aren't the mainline. Free the "info" struct since we're done with
- it.
- (init_psymbol_list): Free any previously allocated psymbol lists.
- (): FIXME: Should realloc-down the psymbol lists when done reading
- the main symbol file?
-
- * symmisc.c (free_symtab): Free fullname field too.
-
- * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
- (REGISTER_ADDR): Make result type unsigned int.
-
- * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
- define REGEX must also define REGEX1 (its dependency).
-
-Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * tconfig/i960: No longer works, points you at vxworks960 or
- nindy960.
-
- * xgdb.c, XGDB-README: Remove file. Users can get the much
- better xxgdb.
- * Makefile.dist: Remove all trace of xgdb.
-
- * breakpoint.c (breakpoint_1): Pass demangle arg to
- print_address_symbolic.
- (clear_breakpoints): Remove unused function.
- (breakpoint_re_set_one): Guts of breakpoint_re_set.
- (breakpoint_re_set): Use catch_errors to do them all anyway.
-
- * gdb-int.texinfo (Host versus Target): Add section on what is
- a "host" feature versus what is a "target" feature.
-
- * infcmd.c (path_command, path_info): Handle the PATH variable
- (object search path) as conveniently as the source search path.
- * environ.c (set_in_environ): Set some vars in GDB's environment,
- in addition to the child's. PATH, G960BASE, G960BIN for starters.
- * source.c (mod_path): New function, from guts of
- directory_command, modifies a path. Used by path_command.
- (directory_command): Call it.
- * defs.h (strsave): Declare.
-
- * utils.c (sevenbit_strings): Add new printing option.
- (printchar): Use it.
- (strsave): Provide this handy helper routine.
- (set_width_command): Rename set_screen_width_command.
- (_initialize_utils): "set screen-width" => "set width";
- "set screen-height" => "set height"; add sevenbit-strings.
-
- * infcmd.c (do_registers_info): Print floating point registers
- in raw hex as well as float format, regardless of whether it is
- a "virtual" convertible register.
- * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
- regs as a double, just in case it's being used that way.
- * values.c (unpack_long): Comment on array/function coercion.

-
- Handle floating point registers in core files.

- first $cdir in path with the compilation directory.
- (print_source_lines): Even if we can't print the lines, set the

-Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * i960-tdep.c (examine_prologue): Add new argument limit,
- which stops the scan at the end of the prologue, or at the PC.
- This fixes a problem where it walks down into the code for the
- user's statements if that code looks like function prologues.
- Mark Fox and I have been bouncing this code back and forth, making
- small changes to it. Callers changed to match.

- Use add_syms_addr_command, not add_file_addr_command, for
- add_file. Break out close routine from existing code.
-
- * dbxread.c (really_free_pendings): Don't free pending_blocks;
- they are in an obstack.
- (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
- Lint.
- (define_symbol): Add symbol type parameter; change callers;

- it to influence the symbol class on the i960.
- (define_symbol): Swap LOC_CONST's into target byte order.
-
- * exec.c (exec_close): New function.
- (exec_file_command): Call it.
-

- instructions.
-
- * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
- obsolete Intel versions in favor of vxgdb versions.
- (check_host, byteswap, byteswap_val, reorder_val): Eliminate
- code dealing with byte order of values, which Intel did in host byte
- order rather than gdb-4's target byte order.
- (i960_frame_chain_valid): Move to nindy-tdep.c.
- (examine_prologue, skip_prologue, frame_find_saved_regs,
- frame_args_address, leafproc_return, saved_pc_after_call,

- saved value over the current value in the topmost frame.
- Cache result in the frame info to avoid performance hair in
- callers.

- (child_ops): Use child_attach, not child_open, to attach.
-
- * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
- set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
- findvar.c to here, since it depends on the contents of the
- shadow_contents of breakpoints, but keep if #if 0 since it is
- never called.
-
- * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
- from i960-tdep.c.
-
- * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
- (ptype_command, display_command): Eliminate have_inferior_p and
- have_core_file_p in favor of target_has_stack or
- target_has_execution.
- (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
- code for actually finding the values of arguments, though we still
- keep track of the maximum stack offset for use in printing unnamed
- arguments. Handle missing FRAME_ARGS_ADDRESS.
-
- * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
- (struct nindy_regs): Define registers passed to/from nindy.
- (nindy_fetch_registers, nindy_store-registers): Translate between

- (vx_xfer_memory, vx_resume): Cleanup status checking.
- (vx_run_files_info): Improve message.
- (vx_load_command): Renamed from vx_add_file_command. Allow load
- to be interrupted.
- (net_ptrace): Remove unused routine.
- (vx_wait): Adopt code from vxgdb960 to cope with broken
- connections to target machine and prompt to disconnect. Remove
- debug printouts. Map some EVENT_'s to SIGnals.
- (add_symbol_stub, vx_open): Print names of object files we found,
- and "ok" if we read their symbols OK. Clarify output in general.
- (vx_attach, vx_detach, vx_kill): Add these commands.
- (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
- (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
- "info files" output, and create_inferior, since we already have
- an inferior.
-
- * stack.c (frame_info): Replace Frame_unknown with 0.
- (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
- (return_command): Pop until the PC matches as well as the FP,
- so it works even if the FP is shared with another function,
- as in "frameless" or "leaf" procedures.
-
- * symfile.c (load_command): renamed from add_file_target_command.
- (add_syms_addr_command): renamed from add_file_addr_command.
- (add_syms_command): Stub to call target_add_syms.

-
- * target.c (kill_or_be_killed, maybe_kill_then_attach,
- maybe_kill_then_create_inferior): Default for attempts to start
- a process, if one is already running, is to ask about killing
- it and retry if yes.

- (SKIP_PROLOGUE): No longer a no-op.
- (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
- (*_REGNUM): Sort register numbers.
- (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
- MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
- REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
- are now 10 byte extendeds, not 8 byte doubles.
- (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
- for nindy versus vxworks targets. FIXME, this should possibly go
- in the target vector.
- (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
- frame_saved_regs and arg pointer with each frame.
- (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.

- (ADDITIONAL_OPTION_HANDLER): use target_load, not
- target_add_file.
-
- * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
- startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
-
- * valarith.c (value_subscripted_rvalue): Avoid handling
- floats and doubles specially; it gave alignment errors. Lint.
-
- * valops.c (value_of_variable, value_of_this): Error if unknown
- value.
-
- * valprint.c (print_floating): Bcopy rather than pointer-deref,
- to avoid alignment problems.
- (value_print): Handle unknown value address.
- (cplus_val_print): Two args are ignored; remove them. Change caller.

-
- * TODO: A woman's work is never done.

- for i960. Change xdr_vectors to xdr_opaques for 68k registers,
- so they will move in target byte order rather than network
- byte order (happens to be the same).
-
-Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
-
-Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)

-
- * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
- HOST_BYTE_ORDER.

-
- * frame.h: Eliminate Frame_unknown in favor of a simple zero.
- tm-vax.h: Ditto.
-
- * value.h: Force value's contents field to be aligned to hold
- at least a double or a long long (if supported). This avoids
- doing bcopy's in and out of the contents field.
-
- (step_1): Avoid coredump under obscure circumstances when we
- have no frame.
-
- * symtab.h (misc_info): Add field to misc function vector for
- any kind of cached information the target code desires. AMD
- 29000 uses this to avoid repeating examine_function_prologue's.
-
- * coffread.c: Lint. Remove static symfile, read_section_header.
- core.c (have_core_file_p): Lint: remove.
- expprint.c (print_subexp): Lint.
- infptrace.c, valops.c, valprint.c: lint.
-
- Roll in changes from vxgdb-5.0.1:
-
- * symtab.h: Comment byte order of each address class. Add
- LOC_LOCAL_ARG for frame-relative args (960).

-
- * symfile.c (prim_record_misc_function): Clear misc_info.
- (fill_in_vptr_fieldno): Check stub type of arg.
-
- * valops.c (value_cast): Avoid looking up names of types whose
- name we don't know, to prevent coredump. Sun CC produces typedef
- rtx and the name of *rtx is zero...
-
-Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Roll in changes from final AMD 29000 port (Tiemann).
-
- tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
- for ../include/a.out.encap.h. This might not work now that BFD
- is separately compiled. Instead, BFD support for encap will have
- to translate machine type 29k into the right COFF_MAGIC.
-
- * infcmd.c: Remove references to inferior_pid that aren't used
- in actual ptrace calls; use target_has_execution, etc.
- (have_inferior_p): Remove function.
- (program_info): Print target info rather than "process number";
- avoid gratuitous messages unless from_tty.
- (run_stack_dummy, finish_command): Set proceed_to_finish.
- infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
- main.c: Lint. Lose have_inferior_p().
- inferior.h (have_inferior_p): Remove, lint.
- (proceed_to_finish): Add flag to ask that all regs be saved
- by normal_stop, for the few commands that need it, speeding up
- serial I/O. Add comments to stop_registers.
-
- * remote-eb.c: Remove newline from breakpoint message we grep
- for. Never time out when running the user program.
-
-
-
-Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Roll in changes from vxgdb-5.0.1:
-
- * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
- symbol in its raw form, we are processing an unlinked ".o" file.
- See if the target environment has assigned it an address, using
- target_lookup_symbol (VxWorks does), and enter it into the symtab
- that way.
-
- * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
- 68k versions for a simpler version that assumes zero FP at bottom.
- Fixes bug of truncated stack reports.
-

- and result, finally.
-
- * target.c (nosymbol): Default routine for target_lookup_symbol.

- zero register "values", and avoid doing cross-net conversions.
- (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
- (vx_open): Rearrange code that attaches to target and reads
- symbols for all loaded modules, to work if some of the modules
- are not accessible. Add symbol_stub() and add_symbol_stub()
- as callbacks from catch_errors(). Allow connect attempt to be
- interrupted painlessly with ^C (FIXME, there are still some bugs
- if the interrupt happens during symbol reading.). Print
- final message with puts_filtered, since symbol messages are
- now filtered too.
-
- Misc cleanup:
-
- * main.c (catch_errors): Only print errstring if non-null.
- (command_loop): Avoid an ioctl per command to test ISATTY.
-
- * remote-vx.c (net_load): make static; avoid sophomoric msg.
- (vx_xfer_memory): Return correct result!
- (vx_files_info): Indicate whether target has float or not.

- tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
- contributor lines and update copyrights to 1991.
-
- Changes from an attempted H-PUX host port:
-
- * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
- defines PT_ATTACH and PT_DETACH but not PT_KILL.
- * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
- * remote-vx.c: include <sys/time.h> for HPUX.
- * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
- "core_file_command" routine to BFD regime. May not work yet.
-
- Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
-
- * xgdb.c: Replace X10 version with some VJ version.
- (FIXME: Its copyright assignment is not on record.)
- * xgdb.c: Update include files to X11R4 (Xaw crud).
- (xgdb_display_source, create_text_widget): fix call to
- get_filename_and_charpos. Rewack source window stuff for X11R4
- (gleaned from include files, and "nm's" of binary libraries, since
- I had no doc available).
- (append_selection, append_selection_word): Disable with FIXME
- since R4 changed interface here.
- (create_buttons): Add back the old set of buttons.
- (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
-
- * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
- Roll VERSION to 3.94 (not yet final though).
-
-Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
- obstack_int_grow, obstack_int_grow_fast): Eliminate
- cast on left of assignment, which gives MIPS cc fits and is
- not Standard C.
-
- * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
- F_ALIAS. Use printf, not fprintf, when not passing a file
- pointer...
- (compare_opcodes): Check that identical instructions have
- identical opcodes, complain otherwise.
-
- * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
- was reported by Roland McGrath.
- (unimp): Only match if exactly zero instruction. (Roland)
- (branches and traps): Generate all variations of these
- instructions with macros, based on a single call that defines
- each condition name and its binary representation.
- (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
-
- * valprint.c (val_print_fields): Take, and use, format parameter.
- This means that "p/x struct" again prints the elements in the
- desired format. Changed callers.
-
- * stack.c (frame_info): Use filtered output, and indicate wrap
- points. Remove kludgy formatting designed to avoid line wrap.
-
- * utils.c (wrap_here): If the line is already full (because
- we had printed a long indent or long wrapped string), do an
- immediate newline-and-indent.
-
- * m68k-pinsn.c (print_insn_arg): Bugfix from
- ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
- instruction is incorrectly disassembled as bkpt #8.
-
- * dbxread.c (end_psymtab): Bugfix from Peter Schauer
- <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
- breakpoint in a *.y file gdb will say Reading in symbols for *.y...
- and then will dump core (sometimes). I traced it back to an
- uninitialized symfile_name in psymtab_to_symtab.
- (const_vol_complaint): Add quotes to message.
- (define_symbol): Only believe line number if gcc_compiled.
- Avoid allocating symbol if we will not return it.
-
- Add target strata support so that newly established targets go
- into their right place in the target stack (e.g. a new exec file
- doesn't wipe out the ability to access the running process).
-
- * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
- remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
- and initialize it properly in all the targets.
-
- * target.h: Document strata. Change return type of push_target.
-
- * target.c (nomemory): new function for dummy memory access.
- (tcomplain): Rename complain, now also used in symfile.c.
- (push_target): Push targets within strata. New return value shows
- whether new target is on top of stack or not. Always keep dummy
- target on stack.
- (target_files_info): Ignore dummy target.
-
- * core.c (core_open): Warn user, and skip accessing file, if the
- core target is not the topmost target in the stack.
- * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
- already handled.
-
- * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
- target_ops, it doesn't belong there since we have no regs there.
- Change name of target from machine => memory to clarify.
-
-Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
-
- * Freeze version 3.93 for release.
-
- * Makefile.dist: Handle vx-share and nindy-share subdirs
- properly when building gdb.tar.Z.
-
- * symtab.c: lint; add no_symtab_msg to consolidate the messages
- printed in various places, so I could change just one copy.
-
- * dbxread.c, coffread.c: Change references to bfd->iostream
- to cast to FILE *, now that BFD avoids needing types defined
- in other header files.
-
-Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
- infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
- sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
- (actually gcc -Wall).
-
- * dbxread.c: Remove first_global_sym, last_global_sym, since
- they are never referenced.
-
- * defs.h (baud_rate): Declare.
- main.c: Define it, and add the -b option to set it.
-
- * gdb-int.texinfo: Add text on how to define a new host or target
- architecture, prompted by Per Bothner's questions about MIPS
- support.
-
- * gdb.texinfo: Document "complaints". Change doc of -q since
- gdb no longer prints the copyright and blurb if you specify a file
- name to be debugged (just like Emacs). Add doc for Nindy-specific
- command line flags for specifying target serial port and such.
- Update copyright to 1991.
-
- * gdbcore.h: Remove a large mass of now-useless crud, since BFD
- has taken over for us the job of ripping up executable files. The
- crud caused Per Bothner's port to not compile.
-
- * infrun.c (normal_stop): Avoid printing "Program exited
- normally" if we are in batch mode. This allows a GDB which
- executes a program on a target system, to behave like a Unix
- command (input from stdin, output to stdout, no extraneous
- output).
-
- * main.c (main): Allow additional machine-dependent command line
- options to be specified with the ADDITIONAL_OPTIONS,
- ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
- ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
- processing to occur just before the main loop with
- BEFORE_MAIN_LOOP_HOOK.
- (main): If a "core file" argument is specified, and it is not a
- core file, try it as a process ID to attach.
- (symbol_completion_function): Attempt to cope with
- "show screen-" TAB, not very successfully. This needs more work,
- FIXME.
- (batch_file): New function, returns whether we are reading
- commands from an interactive tty on stdin, or from somewhere else.
- Called by normal_stop since it doesn't get from_tty passed down
- to it like many commands do.
-
- * remote-nindy.c: Handle command line options for nindy
- connection.
- (nindy_before_main_loop): Prompt user for tty name if they
- don't specify it before getting to the interactive command loop.
-
- * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
- and -r command line options. Also add hook before main loop
- to make it easy to specify a tty.
-
- * TODO: More things to do, one done.
-
-Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
-
- * dbxread.c: Make complaint() calls pass pointer, not struct.
- Add complaints about badly formatted C++ type information
- (const/volatile indicator, and parse errors resulting in
- error_type). Fix C++ virtual member fn comment.
- (read_struct_type): Avoid bumping pointer if we got a parse
- error; this prevents our walking beyond the end of a string.
- Terminate loop on null char as well as semicolon.
- (process_one_symbol): Fix the LBRAC fix so that it uses the
- last previous SLINE, FUN, or SO record's PC address. C++ debug
- symbols did not have SLINE records in a useful order compared
- to the LBRAC records.
- (define_symbol): Handle "catch" records.
-
- * symtab.c (check_stub_type): Added new complain
- `stub_noname_complain' and added a consistency check to
- keep the debugger from crashing when finishing from an
- exception frame. A real fix will be needed later.
-
-Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * infcmd.c (attach_command): Make global.
-
- * Makefile.dist (REMOTE_OBS): Make these compile by default,
- but make them easy to comment out. Perhaps later they should
- be enabled by what CPU you configure for? FIXME.
- (VERSION): Roll to 3.93.
- (pinsn.o): Remove rule for obsolete file.
- (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
-
- Run down a problem that manifested by printing the wrong function
- name in stack traces of read_ofile_symtab. Turned out that the
- problem was the SunOS 4.1.1 (and previous) C compiler outputs
- the LBRAC symbol with an address in the *data* segment, which
- blew our binary search through the blocks.
-
- * dbxread.c: Use the complain() facility consistently to bitch
- about problems in the symbol file we are reading.
- (finish_block): Add code to check the nesting of the blocks;
- complain and Procrust them to fit if wrong.
- (make_blockvector): Check the order of the blocks, complain
- [but don't cope] if wrong.
- (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
- symbols to be sure their PC value is greater than the last SLINE
- (line number) symbol we've seen, complaining and adopting the
- SLINE PC value if wrong.
-
- * symfile.h (struct complaint, complaint_root, complain,
- clear_complaints): Add.
- * symfile.c (complain, complaint_root, clear_complaints): Add
- facility to deal with non-fatal complaints and to regularize their
- suppression.
- (symbol_file_add): Clear complaint counters to allow new complaints.
- (initialize_symfile): Add 'set complaints' and 'show complaints'.
-
- * dbxread.c (dbx_symfile_read): Remember the address and size
- of the string table for the main symbol file, so we won't read it
- more than once.
- (dbx_psymtab_to_symtab): Fix the check for main symbol file,
- to avoid reading the string table yet again. Lint.
- (throughout): Improve filtered output, including word wrap.
- (read_range_type): Improve Bothner's fix to handle other types too.
-
- * utils.c: Improve line wrap implementation. Handle unlimited
- width by making chars_per_line unsigned.
- (puts_filtered): New, easy, function.
-
- * defs.h (puts_filtered): add.
-
- * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
- call the identical sort_symtab_syms() in symfile.c instead.
-
- * expread.y: Suggest the `file' command rather than `symbol-file'.
-
- * command.h (enum var_types): Add zinteger for seroable
- unsigned integer.
- * command.c (do_setshow_command): Handle var_zinteger. Restructure
- nested if's into a switch.
-
- * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
- we did not stop because of a breakpoint (it must have been for
- some other reason, like a "stepi"), so don't print anything.
-
- * symtab.c: Include <sys/types.h> all the time. Now that BFD
- doesn't include <sys/types.h>, old SunOS's require it for
- <sys/stat.h>.
-
-Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
-
- A test port of gdb-3.92.6 to the Sony NEWS.
-
- * Makefile.dist
- Don't normally link in remote- or vx stuff.
- Some of it doesn't compile, and it wastes space for 99% of the users.
- Remove reference to no-longer-used HAVE_VPRINTF.
- Fixed BFD_DEP typo to BFD_DIR.
- * dbxread.c
- Fix cast in arg to bfd_h_getlong.
- Make char *prefix be const.
- Fix how certain range types are mapped into builtin unsigned int types.
- * infrun.c
- Remove 2 #includes. They cause errors (on Sony, at least),
- and aren't needed (they wern't in earlier versions).
- * printcmd.c
- print_address_symbolic should never demangle labels
- (since it prints *assembler-level* labels).
-
- [This was superseded by the change to printcmd below.]
-
- * utils.c
- Add some "volatile" return types to avoid warnings.
- If MISSING_VPRINTF add vprintf function and not just macro
- (since vprintf is used in printcmd.c).
- * valprint.c
- Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
- (The latter isn't grokked by some PCC-based compilers.)
-
- [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
-
- Make chunk size of dont_print_obstack 32*4 instead of default 4096.
- * nindy-share/coffstrip.c
- Added some forward declarations (otherwise, gcc complains
- about implicit extern redefined as static).
-
-Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Changes inspired by Per Bothner:
- * printcmd.c (print_address_symbolic): Take additional parameter
- specifying whether to demangle.
- (print_address): Pass in asm_demangle to control demangling.
- (print_address_demangle): New fn, takes explicit arg to control
- demangling.
- * utils.c: Add new vars demangle and asm_demangle, and let them
- be set and shown.
- (fputs_demangled): If !demangle, just print the argument.
- (fprint_symbol): If !demangle, just print raw symbol.
- * valprint.c (val_print): Call print_address_demangle rather than
- print_address, to cause demangling to depend on the global
- rather than assembler-level demangling setting.
- * WHATS.NEW, gdb.texinfo: Document.
-
- * main.c (show_command): Show all settings if no arg.
- (initialize_main): Make "info set" the same as naked "show".
- * command.c (cmd_show_list): Handle prefix commands in the
- list, and print the name of the setting as well as its English
- description and value.
-
- Allow gdb functions to specify where a line should wrap if it
- exceeds the size of a terminal line. Use it to make the output
- prettier.
- * utils.c (set_screen_width_command): New fn, mallocs a buffer
- of the right size when screen width changes.
- (set_screensize_command, screensize_info): Remove #if 0'd fns.
- (wrap_here): New fn, indicates a point in the output where we
- should wrap the line rather than just letting it overflow at a
- random place.
- (fputs_filtered): Implement wrapping.
- (n_spaces): New fn, returns a pointer to N spaces.
- (print_spaces_filtered): Use n_spaces.
- * defs.h (n_spaces): Declare.
- * stack.c (print_frame_info): Wrap with 4-space indent after
- fn name and before filename and line number.
- * printcmd.c (print_frame_args): Wrap with 4-space indent
- before each argument name is printed.
- * valprint.c (value_print): Wrap with no indentation before
- each repetition.
- (val_print_fields): Wrap with indentation relative to nesting
- level before each field name.
- (val_print): Wrap with nesting indentation before array elements.
- * command.c (do_setshow_command): Avoid extra newlines,
- wrap with 4-space indent around values printed, end with period.
- * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
-
- * breakpoint.c (breakpoint_1): Implement addressprint for
- "info breakpoints" display. Change file name and line number
- format to " at file:nnn" rather than " (file line nnn)".
- * gdb.texinfo: Document.
-
-
-Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Frozen for gdb-3.92.6 release.
-
- README, WHATS.NEW: Update for 3.92.6 release.
-
- tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
- coffread.o from configs since it is now built by default.
- tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
- i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
- pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
- from configs since it is now built by default.
-
- Makefile.dist: Update for release 3.92.6. Handle files that
- have been moved to ../include, ../getopt, or ../bfd. Add
- saber.suppress and tests directory. Add config.status to
- the release (it will say "none").
-
- coredep.c: Minor formatting fixes.
-
- These changes were made in early December but only checked in now:
- * nindy-share/Onindy.c, nindy-share/coffstrip.c,
- nindy-share/nindy.c: lint
- * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
- register values coming back from the target; we store values
- in target byte order everywhere.
-
-Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
-
- * valprint.c (cplus_val_print, val_print_fields): New functions,
- which print C++ objects. They conspire to avoid printing a
- virtual base class more than once, following all the twists and
- turns of C++ virtual base rules.
- (val_print): Call the above rather than do it by hand.
-
- * symfile.c (symbol_file_add): Only reset symfile_mtime for main
- symbol file, not for added files like shared libs. This really
- needs to be generalized to a timestamp per file.
-
- * core.c (cleanup_core): Avoid coredump if no core file.
-
- * config.gdb: Accept -host or -target in place of +host or
- +target.
-
- * coffread.c (find_linenos): Avoid desupported BFD interface
- to line numbers. We still read them manually rather than using
- BFD's "generic" features.
-
- * gdbrc.tex, threecol.tex: Add GDB reference card and its
- formatting code.
- Makefile.dist: Add refcard to OTHERS list for creating tar files.
-
- * Makefile.dist: Eliminate use of $< in explicit targets.
-
- * readline/Makefile: Use $< rather than $*.c, which does not
- include the VPATH in GNU Make.
-
- * tconfig/i960-bout, tconfig/i960-coff: These are identical
- copies of tconfig/i960, added for global configuration
- compatability. All i960 versions can read both coff and b.out.
-
- * tm-88k.h: Fix multiline macro that lacked \'s. Remove
- COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
- automaticaly.
-
- * TODO: Think of more things to do.
-
-Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
-
- tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
- of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
- 64-bit float conversion.
-
- tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
- equivalent to sun?os4 so global config works.
-
-Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
-
- Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
-
- * main.c: Only declare linesize once; declare pagesize not at
- all, since it is never used.
- (main): Clear newly allocated line before it is used.
-
-Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
-
- Further stabilization for the Intel 960.
-
- * Makefile.dist: Parameterize the location of the "include"
- and "bfd" directories, as well as "getopt". Add symfile.c.
- Link in both dbxread and coffread. Fix up "make depend" to
- rewack the locations of include, bfd, and getopt in its output.
-
- * README: Document moving include files, improve some of
- the other doc.
-
- * coffread.c: Move common code out to symfile.c. Change
- symbol_file_command style interface to use new *_symfile_init
- and *_symfile_read interface under BFD. Use BFD internal
- info to locate line table, symbols, etc.
-
- * core.c (core_fetch_registers): Rename to get_core_registers
- to avoid confusion with fetch_core_registers.
- (register_addr): Move to coredep.c, which is already machine
- dependent. This leaves core.c pretty clean of dependencies.
-
- * coredep.c (register_addr): Accept this routine from core.c.
-
- * dbxread.c: Move common code (with coffread.c, etc) into new
- symfile.c. Each psymtab now contains a pointer to the
- format-dependent function that knows how to read it in. Make
- some things static.
- (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
- (process_one_symbol): Add code to complain about a "compiler bug
- we muzzle here", if we actually see it.
-
- * eval.c (evaluate_subexp): Insert missing "break" statements
- in code that determines whether a variable is an lvalue in
- memory, register, or whatever. I detected this via a compiler
- bug in which it *almost* mashed out the whole switch statement.
-
- * gdb-int.texinfo: Add minor sections on configuring gdb for
- release, and about the README file.
-
- * infcmd.c (registers_info): Fix formatting somewhat. Still
- not as pretty as before, but it handles byte swapping.
-
- * remote-nindy.c: If data cache routines are interrupted while
- waiting for the remote end, be sure that any uninitialized cache
- blocks are on the free list, not on the valid list!
-
- * symfile.h: Flesh out this header file with all the various
- routines and variables that have been merged in from dbxread.c
- coffread.c, and symtab.c to symfile.c.
-
- * symfile.c: New file, containing code common to dbxread.c,
- coffread.c, and some code from symtab.c. All generic code for
- reading symbol files should be in here now.
- (unrecord_misc_function): Remove unused function.
-
- * symtab.h: Remove file-reading things to symfile.h.
-
- * symtab.c: Remove file-reading things to symfile.c.
-
- * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
- to decode i960 fault types.
-
- * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
- target.c: Change type of the "resume" function from int to void,
- since its result was never used.
-
-Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
-
- * main.c: Replace "stupid" with "caution"; you now "set caution
- on or off".
-
- * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
-
- * infcmd.c (do_registers_info): Call val_print to deal with the
- byte order of the registers being printed. FIXME, this makes
- the formatting of the output uglier.
-
- * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
- defined, call it for signals the debugger doesn't itself use.
- The i960 uses this for more detailed fault information.
-
- * remote.c (remote_open): If arg is null, print help rather than
- dumping core.
-
- * sparc-xdep.c (register_valid): Avoid declaring size, since
- various modules will think of various sizes depending on the
- architecture of their tm-file. FIXME, we need protection against
- actually entering one of those modules, which would clobber
- storage if not for the target architecture compiled into gdb.
-
- * stack.c (up_command, down_command): Always print the frame
- you arrive at.
- (up_silently_command, down_silently_command): New commands
- for use in scripts.
-
- * i960-pinsn.c (reg), i960-tdep.c: Lint.
-
- * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
- more parameters than it used to.
-
- * findvar.c (registers): Increase slop to 256 bytes, which should
- protect us against even most RISC machines with large register
- sets.
- (locate_var_value): Move declaration inside related ifdef.
-
- * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
- throughout, to avoid throwing away buffered input from the board.
- (nindy_wait): Supply_register takes addr_of_value, not value.
- (i960_print_fault): Renamed from i80960_fault.
- (nindy_fetch_registers): Avoid have_regs stuff, just get them.
- (nindy_store_registers): Avoid regs_changed stuff, just stuff
- them.
- (nindy_create_inferior): Don't bother to write PC_REGNUM since
- we can set the PC in the call to proceed(). Unpush nindy_ops
- before pushing it on top, to avoid message to user. Eliminate
- commentary from Unix machines that just misleads here.
- (reset_command): Fix error message to suggest target command.
-
-Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
-
- Release 3.92.5 as frozen.
-
- Stabilize the merged release...with help from lint, Saber C,
- gcc -W, etc.
-
- Everywhere: Add include files needed to declare return types
- of functions called.
-
- * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
-
- * breakpoint.h: Add undeclared breakpoint functions, and some
- functions for display handling since I couldn't think of a better
- .h to put them in.
-
- * breakpoint.c (insert_breakpoints): Make code for disabling
- shared library bkpts more likely to work. It's used when we
- rerun a program and stop before the shared library has been
- mapped in.
- (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
- cast from pointer, so it squeezes through catch_errors.
- (bpstat_stop_status): Fix logic broken some time ago. We now
- always create a bpstat if the stop address matches a breakpoint,
- even if we don't stop there -- just like the old code used to do
- before I got my fingers into it (sigh).
- (breakpoint_1): Print "ignore count" after "stop only if"
- condition, since that's how it actually works.
- (mention): Handle watchpoints as well as breakpoints.
- (watch_command): use set_raw_breakpoint and mention to do most
- of the work (and initialize all the fields!). Only pass one
- arg to parse_c_expression, since that's all it takes.
-
- * command.c (not_just_help_class_command): Rename arg to args
- since we ignore "unused argument" warnings on vars named "args".
- inflow.c (child_terminal_info): ditto.
- infptrace.c (kill_inferior): ditto
- main.c (catch_errors, version_info, quit_command, pwd_command,
- source_command, dump_me_command, editing_info,
- set_history_size_command, set_history, show_history,

- reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
- text_end, exec_data_start, exec_data_end, text_offset,
- exec_data_offset, data_offset, stack_offset). They're
- superseded the more general build_section_table and
- xfer_memory.
- (get_exec_file): Mention the `file' command.
- (read_memory_check): Rename to memory_error, and only call it
- in the case of an actual error.

- (fetch_core_registers): Rewrite to actually work, I hope.
-
- dbxread.c: Use a.out.gnu.h, not system a.out, now.
- Replace index() with strchr(). Remove all the pre-BFD macro

- dbx_symfile_init needs to pass to dbx_symfile_read in this
- struct.
-
- (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
- dbx_symfile_discard): Rearrange symbol file reading to divide
- the format-specific part from the format-independent part,
- leaving the format-independent part such as file name expansion
- and opening in symtab.c. This replaces
- partial_symbol_file_open and partial_symbol_file_read.
- Symbol_file_read, add_file, add_file_target_command,
- add_file_addr_command move to symtab.c. Pass an explicit
- "mainline" flag for when reading the main symbol table, rather
- than relying on the offset address to be zero or nonzero.
-
- (dbx_symfile_read): Don't allow void *'s to be printed as
- typedefs.
- (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
- (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
- macro" debug version really work.
- (read_dbx_symtab): Remove unref'd parameter inclink.
- Avoid swapping N_SLINE symbols, for speed.
- Merge N_TEXT!N_EXT case with the other external symbol
- definitions' case. Add comments.

- (read_range_type): Add FIXME about comparing a long to 1<<32.
-
- * coffread.c: Minor changes to move things closer to the new
- regime with symtab.c and dbxread.c Major work is still needed
- here.
-
- * exec.c (exec_file_command): Remove old variables (see core.c
- above).
- (xfer_memory): If memory transfer is right at the end of a
- section, don't lose.
-
- * findvar.c (get_saved_register): If value is in a real
- register, LVAL is lval_register, not lval_memory.
-
- frame.h: Declare print_sel_frame and record_selected_frame.
-
- gdb-int.texinfo: New file, for GDB internals documentation.
- Very simple, unformatted doc of cleanups is there for now.
-

-
- getopt.c: Declare char *alloca(); even on SPARC.
-
- infcmd.c (run_command): Call target_kill rather than
- kill_inferior.
- (step_command, next_command, stepi_command, nexti_command):
- Declare from_tty parameter even though we don't use it.
- (run_stack_dummy): argument BUFFER is a char array, not
- a pointer to REGISTER_TYPE.
- (finish_command): using_struct_return needed a value *,
- not a struct symbol *.
-
- * infptrace.c (child_xfer_memory): To avoid dependency on
- where sections are in memory, try PT_WRITE_D and if that fails,
- try PT_WRITE_I. Most Unixes don't care which you use.
-
- * infrun.c (step_resume_break_shadow): Change to array to
- match other breakpoint shadow storage.
- (clear_proceed_status): Pass address of bpstat to
- bpstat_clear, not the bpstat itself.
- (child_create_inferior): FIXME comment about if the child
- exits.
- (start_inferior): Remove old function.
- (child_open): Use target_kill rather than kill_inferior.
- (wait_for_inferior): Ditto.
- (insert_step_breakpoint, remote_step_breakpoint): Use

- pretend that the one being waited for exited with signal 42.
-
- * main.c (command_line_input): When scanning for comments,
- don't coredump on unclosed quotes.
- (quit_command): Use target_kill rther than kill_inferior.
- (_initialize_main): Rename class_user from "user" to
- "user-defined".
-
- * printcmd.c (print_command_1): Initialize "fmt" if no format
- is specified by the user.

- * remote-eb.c (eb_open): Avoid coredump on no argument.
-
- * remote-nindy.c: Bring out of Intel environment into new
- target environment. Remove all conditional compilation on
- I80960. Massive hacking throughout.

- to get error checking.
- (vx_add_file_command, vx_open): Use symbol_file_add rather than
- add_file.
- (vx_create_inferior): Use target_terminal_ours...
-

- we need the table for things other than psignal.
-
- * solib.c (solib_add): Use symbol_file_add, not add_file.
- (solib_address): Return boolean result rather than struct
- pointer which nobody else knows the type of.

- target_write_memory, to get error checking.
-
- * stack.c (locals_info, catch_info, args_info,
- get_selected_block, frame_command, up_command): Use
- target_has_stack, rather than have_inferior_p or

-
- * symfile.h: New file, defining the interface between the
- generic and object-file-specific symbol reading code.
-
- * symtab.c: Move generic symbol-reading interface to symtab.c,
- from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
- table to map BFD targets to symbol-reading modules in GDB.
- Change index to strchr.
- (lookup_struct_elt_type): Use error() rather than hand-made
- simulations thereof.
- (lookup_partial_symbol): Speedup slightly when length == 0.

-
-
-Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
-
- Continuing Intel 960 port merge of GDB.
-
- * Makefile.dist: Merge i960 "nindy-share" files. Rename
- malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
- Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
- Wack over "make depend" so it handles files in subdirectories
- vx-share, nindy-share, bfd, and in the current directory.
-
- * blockframe.c (get_prev_frame_info): Remove fatal error
- if stack not defined.
-
- * core.c (core_open, core_detach): New functions that handle
- the old "core-file" command as "target core" and "detach" instead.
- (core_file_command): Call them.
- (core_xfer_memory): Use common routine xfer_memory.
-
- * dbxread.c: Include a.out.gnu.h, not system a.out.h.
- dbxread now uses bfd for everything but symbol reading itself.
- BFD internals are used to drag out the relevant file offsets.
- (partial_symbol_file_open): Change args all around for BFD.
-
- * symtab.c: Rename "value" to "val" everywhere, so we can
- #include "value.h".
- (symbol_file_command): New command, moved from dbxread.c
- and coffread.c. It uses BFD to read the file, then vectors
- based on its type, to dbx or coff symbol readers.
- * symtab.h: Extern a few vars for symbol_file_command.
-
- * target.h: Breakpoint takes a char * save area, not a char **.
-
- * valprint.c (val_print): When unpacking bitfields, offset
- the address in gdb of the value, if it is declared with a shorter
- type. Remove the last "runtime kludge test" of host byte order.
-
- * utils.c: Remove old my_bfd_read routine.
-
- * stack.c (frame_info): Use target_has_stack. Print program counter
- register's actual name rather than "pc", since it's called the
- "ip" (instruction pointer) on the i960 (sigh).
-
- * target.c (target_command): Add command for selecting a target
- type and calling its open routine. This is used for initiating
- communication with a particular target, in a generic way.
-
- * tm-i960.h: Update for modern gdb. Remove semicolons from
- various macros. Handle reading struct return convention, and
- error-out attempts to return structs with the "return" command.
- Be sure gdb doesn't think we know how to call functions in the
- inferior.
-
- * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
- to i960_xxx in lower case.
- (arg_address): Circumvent errors due to LOC_ARG_BLOCK
- not being defined yet.
-
- * remote.c (remote_open): Call start_remote to initialize
- wait_for_inferior during open.
- (remote_xfer_inferior_memory): Return length written rather
- than errno value.
-
- * remote-vx.c (target_command -> vx_open): Use new generic
- target command.
- * remote-eb.c, inftarg.c, exec.c: ditto.
-
- * infrun.c: Fix comments.
- (attach_program -> child_open): Use new generic target command.
- (wait_for_inferior): Clear saved register values before target_wait,
- so target_wait can set some of them if convenient.
-
- * infptrace.c (fetch_inferior_registers, store_inferior_registers):
- Return success indicator, not void.
- (child_xfer_memory): Avoid fetching initial word if we'll
- overwrite it anyway.
-
- * infcmd.c (attach_command): Use new generic target open routine.
- (_initialize_infcmd): Update doc on attach and detach commands.
- (do_registers_info): Merge in a byte-order problem as a FIXME
- comment.
-
- * findvar.c (find_saved_register): Avoid problem in current frame.
- (read_relative_register): Ditto.
- (write_register): Convert byte order on the way out.
-
- * exec.c (file_command): Add.
- (add_to_section_table, exec_command): Use new bfd_map_over_sections.
- (xfer_memory): Common function between core_xfer_memory and
- exec_xfer_memory.
- (exec_xfer_memory): Use it.
-
- * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
-
- * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
- valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
- infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
-
-Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
-
- Merge Intel 960 port of gdb, continuing...
-
- * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
- symbol_file_command): Pass from_tty arg to hush 'em up.
-
- * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
- Add magic numbers for 960 COFF format.
-
-Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
-
- Merge Intel 960 port of gdb, from Intel "1.2" release.
-
- CHANGE_LOG entries from their port, which was based on
- gdb+-2.8.0:
-
- Thu Sep 6 11:02:22 PDT 1990
- Remove temp file if download is interrupted.
-
- Wed Aug 1 09:08:33 PDT 1990
- Now uses binary protocol to talk to NINDY.

- Times out after 5 seconds when trying to talk to NINDY.
-
- Tue May 29 12:54:49 PDT 1990
- Added variable baud rate (-b switch).
- Source code reorganization.
-
- Thu Apr 26 11:09:55 PDT 1990
- More cleanup of batch mode; specifically, execute "-s", "-e", and
- "-se" switches as soon as they are encountered on the invocation line.
-
- Fri Apr 20 13:47:15 PDT 1990
- Add -brk switch.
-
- Thu Apr 19 09:54:28 PDT 1990
- Add 'reset' command.
-
- Wed Apr 18 09:48:07 PDT 1990
- After opening remote tty, wait for 1 second to go by without input
- from it before trying to talk to NINDY (fixes problems with the
- Heurikon HK80/V960E).
-
- Mon Apr 4 16:33:05 PDT 1990
- Some output was not being suppressed in 'batch' mode.
-
- Thu Mar 22 15:31:11 PST 1990
- Ask user if old symbol table should be deleted when new file is
- downloaded.
-
- Allow user to run a program downloaded before gdb960 was brought up.
-
- Correct "exec-file" help message for i80960 context.
-
- Correct bug in calculating user space address: could occasionally
- corrupt user program.
-
- Make sure to zero low-order bits in rip's because of bug in 960CA
- A-step part: could cause operation faults when "next"ing across
- a function call.
-
- Correct bug that made it impossible to get source line numbers for
- code loaded at addresses higher than 0x7fffffff.
-
- Wed Jan 10 12:43:22 PST 1990
- Open remote tty for exclusive use.
-
- Fri Jan 5 12:14:42 PST 1990
- Correct disassembly (CA manual was right after all):
- opcode for sysctl is 0x659
-
- Mon Oct 23 12:03:04 PDT 1989
- Use G960BASE and G960BIN environment variables to find 'sx' utility.
-
- Mon Oct 16 14:15:09 PDT 1989
- "sfr0"-"sfr31" should have been named "sf0"-"sf31"
-
- Mon Oct 2 15:56:31 PDT 1989
-
- Added 960CA disassembly support.
-
- To simplify maintenance:
- - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
- directly instead.
- - eliminated opcode.h: incorporates tables into i960-pinsn.c
- - moved 960-specific routines from i960-pinsn.c to i960-md.c
- - made disassembly interface identical to that in gdmp960.
-
-
-
-Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
-
- * target.h: Allow targets to stack. Add target_has_memory,

- * remote-eb.c: New memory regime, new info files.
- * remote-vx.c: New memory regime, new info files. Now use
- separate targets for VxWorks attachment to machine, and
- actually running a process under VxWorks, since one has
- stack & execution & regs and the other doesn't.
- * remote.c: New memory regime, new info files.
- * sparc-xdep.c (fetch_core-registers): New memory regime.
- * target.c: New routines and support for stacked targets,
- new memory regime, new info files regime.
-
-

- * gdbcore.h: Add struct section_table.
- * exec.c (build_section_table): Iterate all sections and
- record what gdb needs to know about them.
- (exec_command): Use it.

-
- * TODO, Projects: Lots more stuff to do...
-
-Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
-
- Massive changes to wall off the remote-debugging interface
- behind a function vector. The port to handle VxWorks targets
- is also part of this.
-
- All files: Replace references to renamed functions,
- remove references to remote_debugging, remove references to
- have_include_file, have_core_file in favor of target_has_stack,
- target_has_memory, etc.
-
- * Modularize the breakpoint interface.
- breakpoint.h (BREAKPOINT_MAX): New define sets max length of
- a breakpoint instruction.
- breakpoint.c: struct breakpoint's shadow_contents now sized as
- BREAKPOINT_MAX.
- (insert_breakpoints): Vector to target to install breakpoints.
- (remove_breakpoints): Vector to target here too.
- Remove REMOTE_SA_SPARC kludges and other remote_debugging.
- sparc-tdep.c (single_step): Use new breakpoint interface for
- the single-step breakpoints.
- mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
- New file, contains routines to insert and remove breakpoints by
- reading out the old contents and later replacing them. This is
- how ptrace breakpoints work, and many remote systems as well.
-
- * tm-vxworks68.h: New config file, overrides a few things for
- Wind River's preferences.
-
- * target.h: New file, for transfer vector used to talk to the
- inferior (child, attached, core, exec, remote, etc). All accesses
- to the thing being debugged should come through these vectors.
- target.c: New file, routines to handle transfer vector.
- (various files): Add transfer vectors XXX_ops for the various
- targets and pseudo-targets (core files, etc) we support.
-
- * breakpoint.c (bpstat_stop_status): Further explorations of
- watchpoints and why things don't work all the time.
- (bpstat_alloc): New fn to allocate a bpstat and chain it.
-
- * config.gdb: Only add "source ${srcdir}/.gdbinit" to
- the local gdbinit if it doesn't already have it.
-
- * core.c (core_ops): add and install.
- Allow core debugging without exec file.
-
- * dbxread.c (free_and_init_header_files): Merge two fns.
- (end_symtab): Free named symbol table when a new version comes in.
- (read_dbx_symtab): Relocate all kinds of symbols with base
- address. First step toward handling different text, data, bss
- reloc.
- (add_file_addr_command): Renamed add_file_command.
- (add_file_command): Vector to remote handler.
- Add "load" as an alias for "add-file" command.
-
- * defs.h: Allow "volatile" to be used in non-ANSI; use it for
- non-returning functions.
-
- * exec.c: Add exec_ops, and push it as a target when an exec
- file is specified.
-
- * infcmd.c (run_command): Pass executable file name and arg list
- separately when starting an inferior. Permit "run" when no exec
- file is specified, for VxWorks.
- (detach_command): Move to child_detach in inftarg.c.
-
- * inftarg.c: New file. Unix-child-specific routines, and the
- child_ops structure.
-
- * inferior.h (registers): Export "registers" as the way for
- target dependent register handlers to find gdb's local copy of
- the registers. Rename "stop_after_attach" to "stop_soon_quietly"
- since it is now used by places that want wait_for_inferior to
- handle the grunge but want to see every trap from the inferior.
-
- * inflow.c (create_inferior): Pull out, and merge into infrun.c.
- Eliminate remote_debugging hooks in terminal handling.
-
- * infrun.c: Replace start_inferior with child_create_inferior.
- Move all the hair of Unix shells and ptrace idiosyncracies into
- child_create_inferior, so remote handlers don't have to deal.
- Remove running_in_shell. Rename stop_after_attach to
- stop_soon_quietly, and use it in a few other places where we want
- to just call wait_for_inferior and get control back on the first
- trap. trap_expected now never takes a value > 1.
- (init_wait_for_inferior): Initialize static vars when a new
- process is created.
-
- main.c (gdbinit): Add new hook for .gdbinit file name, let
- it be overridden by config files as GDBINIT_FILENAME.
- (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
- Both of these are used for VxWorks gdb.
-
- mcheck.c: rename include file "gmalloc.c" to avoid problems
- with system include file "malloc.c".
-
- param-no-tm.h: New include file, same as param.h but does not
- include the default "tm.h" file. This is used in files where
- the target is known, e.g. remote-eb.c or sparc-xdep.c.
-
- param.h: Now just a shell that includes tm.h and param-no-tm.h.
-
- remote-vx.c: New file, VxWorks remote debugging support. Uses
- RPC routines that are shared with the target system, in directory
- ${srcdir}/vx-share.
-
- remote.c: Vectorize remote interface.
-
- source.c: Globalize source_path, and make an alias "l" for "list"
- since we now have the "load" command.
-
- sparc-xdep.c: Use new param-no-tm.h.
-
- symmisc.c (free_named_symtab): Add new function from Wind River.
- However, ifdef it out for now while we think about what it should
- really be doing.
-
- tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
- PREPARE_TO_STORE to
- the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
- non-Unix-children handle this with their own code in the target
- transfer vector.
-
- Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
- source and target lists. Add vx-share to default list of include
- directories. Add new files to src and target lists: mem-break,
- target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
- ${srcdir} versions of munch and createtags are used.
-
- * valops.c (find_function_addr): Split out of call_function.
- (call_function_by_hand): Rename call_function; this function
- calls functions in the target by laboriously patching the target
- word-by-word with the right stack, args, regs, etc.
-

- * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
-
- * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.

- * defs.h (xmalloc, xrealloc): ditto
-
- * utils.c (quit): Grab the terminal from the child if necessary.

-
-Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
-
- * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
- bfd stuff is still screwed up, but with some manual work, it
- compiles.
-
- * breakpoint.c (bpstat_do_actions): Start over if a command
- proceeds the inferior, since the inferior will have stopped and
- will need to have its new stop-actions taken care of.
-
- * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
- compiler fits, simplify it.
-
- * gdb.texinfo (directory command): Doc new dir command.
- source.c (directory_command): "dir" now puts things on the front
- of the path, moves dups up front, and handles multiple names
- on the command line, inserting each one in order. It also
- blows away cached line and full_filename info.
-
- * stack.c (backtrace_command): Skip "more stack frames follow"
- unless interactive.
-
- * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
- xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
- xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
- The only odd one was Gould NP1, which had defined vprintf to
- "printf"!!!
-

-
-Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
-
- * printcmd.c (call_command): add an alias for the "print" command
- which runs expressions and doesn't print the result if void.
- (print_command_1): implement it.
-
- * command.c: Remove #if 0'd code. Initialize all the fields
- in add_cmd (). Rename do_nothing_command to
- not_just_help_class_command, and make it externally visible.
- command.h: add user_commands to struct.

- string as well as a function pointer.
-

- calling convention of value_struct_elt () that got dropped in
- merge.

- saving ptrace calls.
- * infrun.c (proceed): handle DO_DEFERRED_STORES.
- * tm-sparc.h: define DO_DEFERRED_STORES.
-
- * sparc-xdep.c (store_inferior_registers): when storing float
- registers, don't store stack regs too. When storing the SP,
- however, DO store the stack regs too. This fixes a bug in which
- the dummy frame is not recognized when a call_function finishes,
- because its frame pointer (in the stack regs) was never
- initialized.
- (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
- even though we don't know how to read them from an inferior.
- valops.c (call_function): Comment about storing SP.
-
- * infrun.c (save_inferior_status): Save away the original bpstat
- chain so it can be restored later. Install the copied version for
- use by whoever saved the status. It will be blow away by
- restore_inferior_status, and the original chain restored. This is
- important for people who have pointers into the original.
-
- * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
- findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
- main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint

-
-Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
-
- * Merge Mike Tiemann's multiple inheritance changes from Sun.
- Store the baseclasses in a type struct starting from array element
- 0 rather than from the unusual array element 1.
-
- dbxread.c: the above.
- (virtual_context): Add
- Read new debug information about which virtual function table
- a virtual function is from, and store it in fn_field.fcontext.
-
- symtab.h: Add fcontextt. Fix baseclass indices. Typo in
- TYPE_FN_FIELD_STATIC_P.
-
- symtab.c: the above.
- valops.c: the above. Handle pointer casts of object *'s.

- (value_struct_elt): First arg is now a pointer to a value, and is
- modified on return.
-
- valprint.c: the above.

- * dbxread.c (read_struct_type): Clear bit vectors whenever
- we allocate one.
- symtab.c (B_CLRALL): define.
-

- wherein builtin_type_int becomes TYPE_CODE_FLT.
-
- * core.c (info_files): Show the inferior pid.
-
- * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
- already knows how to look in the source directory.

- been read in.
-
- * source.c (open_source_file): Quick path if we have already
- located the source file by its full name.
-
- * symtab.c (lookup_symbol): Use find_pc_symtab rather than
- find_pc_psymtab. When a name is found in the misc function
- vector, search the symbol table for its mangled name, not the
- name that the user typed.
-
- * bfd.h: Fix missing comment terminators, make #endifs match.
-
- * valarith.c (value_less): Handle unsigned int comparisons.
- Add FIXME about pointer compares, which assume host and target
- pointers are the same.
-
- * command.c (do_nothing_command): lint
- dbxread.c: lint. Remove sort_syms. Document C++ visibility info,

- valarith.h: use <string.h>
- solib.c (solib_add): lint.
-
-Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)

-
- * Initial BFD (binary file diddling library) merger:
- coffread.c: Change AOUTHDR to struct exe_hdr.

- (my_bfd_read): More bogosity, which I don't think we call.
- (program_name): Remove this atrocity asap!
-
-Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
-
- * From Per Bothner:
- values.c: allocate_repeat_value was not clearing the
- optimized_out field.
- (value_static_field): minor stylistic fix (wrong macro was used).
- valops.c (value_struct_elt_for_address): didn't work for C++
- static fields.
-

-
- * tm-sun3.h (PREPARE_TO_STORE): fix typo.
-
-Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
-
- * tconfig/sun3os4: Remove warning about native assembler,
- since it also occurs in the xconfig file.
-
- * findvar.c (registers): Allocate some slop after `registers'
- to prevent stray accesses from trashing the next variable.
-
- * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
- on the sun-3, by changing the #ifdef from `sun3' (which is not
- defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
- vars, which happened to follow `registers' in the executable.
-
- * readline/history.c (history_search): Heed gcc-2's advice
- and parenthesize && inside ||).
-
- * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
- tm-29k.c: Insert FSF copyright headers.
-
- * remote-eb.c: Better comments.
-

-
- * inferior.h (PC_IN_CALL_DUMMY): New macro.
- infrun.c (wait_for_inferior, 2 places): Use it.
-
- * values.c (value_being_returned): Only use
- EXTRACT_STRUCT_VALUE_ADDRESS if defined.
-
- * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the

- case.
-
-Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
-
- * Allow a Makefile to be built without building the
- tm and xm file links that screw up builds in subdirectories.
- This is done with `config.gdb none', then you can do things
- like `make gdb.tar.Z'.
- * tconfig/none: Config file for no target system
- * xconfig/none: Config file for no host system
- * config.gdb: If no TM or XM files are called out by the
- host or target file, don't make links for them.
-
- * cplus-dem.c: Add documentation.
-
- * dbxread.c (read_ofile_symtab): Turn a fatal error into a
- simple error, so the user's gdb doesn't crash due to some object
- file problem (e.g. somebody is rebuilding the file out from under
- gdb).
-
- * printcmd.c (print_address_symbolic): demangle the symbol.
-
- * Makefile.dist (OTHERS): Remove tdesc-lib because it has
- Motorola copyrights in it. Make "make gdb.tar.Z" work.
- (alldeps.mak): sort and uniq all results from this; duplicates
- hose gdb.tar.Z link building. Remove RCS files from
- tconfig and xconfig. Add config files for sun386. Add
- a few odd files to OTHERS and HFILES.
-
-Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
-
- * Makefile.dist: Pull solib.c to tconfig/sun?os4.
- Roll version number to 3.91.5. Make lint work in bindir.
-
- * README: Document cross-debugging and new file structure.
-
- * blockframe.c: Lint. Include "value.h" to declare read_register.
- (find_pc_partial_function): remove duplicate line.

-
- * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
- Clean up usage of misc_function_type. Declare some CORE_ADDRs.
-
- * config.gdb: Allow `config.gdb host target' form. Clean
- up previous change that printed bogus messages when you just said
- `config.gdb'.
-
- * core.c: #include "command.h" for lint.
- * dbxread.c: lint
- * eval.c: lint
- * main.c: Remove some casts of enums. Lint.
- * source.c: lint
- * symtab.c: lint
- * symtab.h: lint
- * expread.y: lint
- * valarith.c: lint
-
- * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
-
- * sparc-tdep.c (isannulled): Take instruction as parameter, don't
- read it from memory. This will allow us to save ptrace calls
- eventually. Changed caller single_step too.
-
- * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
- that we aren't going to use, saving many ptrace calls, especially
- when watchpointing or single stepping. Use some #define's for
- constants.
- (store_inferior_registers): Ditto.
- (core_file_command): Use some #define's for constants.
-
- * tm-sparc.h: Add #define's for some register numbers, so we
- can eliminate the use of random constants in sparc-xdep.c.
-
- * stack.c (frame_command, print_frame_info, up_command,
- down_command) Remove frame_changed, since it
- causes a bug and doesn't seem to do anything useful. In some
- places it was used as a flag, in others as a stack level (?).
-
- * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
- default is to use the portable (vprintf) version rather than the
- kludge version.
- * xm-news.h (MISSING_VPRINTF): Add.
-
- * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
-
-Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
-
- * Remove stuff that forces -Bstatic linking of gdb, and warnings
- about linking debugged programs -Bstatic in the sun?os4 config
- files in tconfig and xconfig subdirectories.
-
- * main.c (main): Remove unreached exit(0) now that we exit
- via quit_command().
-
- * Create TODO file for online bug list. There are too many
- "little" bugs to keep track of on paper.
-
- * Change Projects file to refer to bug-gdb@cygnus.com
- rather than kingdon@ai.
-
-Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
-
- * Makefile.dist (VERSION): 3.91.4 now.
-
- * symtab.c (init_misc_bunches): Rename from init_misc_functions.
- (condense_misc_bunches): Add sanity check that misc_count is
- the same as the number of symbols in the bunch.
-
- * coffread.c: rename init_misc_bunches. Pass an argument
- to condense_misc_bunches (a zero).
-
- * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
- every time we are called; don't rely on our caller to do it.
- (add_file): Remove call to init_misc_bunches.
-
- * mipsread.c: Only warn, don't error, if unknown symbol types.
- This keeps an old gdb from falling on its face if it sees newly
- extended symbol info. Rename init_misc_bunches.
-
-Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
-
- * Merge in changes from Per Bothner for DECstations and other
- MIPS stuff. The rest is Bothner speaking:
-
- The next message is a merger of Alessando Forin's mips port with
- mine. I've tried to use my good if biased judgment to get
- the best of both. It *does* need testing.
-
- Some of the changes are general, *not* mips-specific.
-
- param.h:
- Didn't believe in little-endian bit order.
- There are still inconsistencies about whether flags
- like BITS_BIG_ENDIAN are integer (#if ...) or
- boolean (#ifdef ...). I tried to paper over them.
-
- dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
- Moved some misc_function code that was common to
- {dbx,coff,mips}read.c to symtab.c.
- In the process, I think I cleaned things up a bit.
- At the same time, moved obsavestring and obconcat to symtab.c.
-
- dbxread.c:
- Removed obsolete condense_addl_misc_bunches (use
- condense_misc_bunches(1) instead).
-
- exec.c:
- Needed to include <sys/dir>, at least on DECstations.
-
- valops.c, mips-tdep.c, tm-mips.h:
- Added PUSH_ARGUMENTS macro to support funny argument-pushing
- conventions (when STACK_ALIGN is insufficient).
- Needed on mips, where doubles need 8-byte alignment,
- but ints only need 4.
-
- mips-opcode.h:
- Removed cruft that was not being used.
- Merged in many fixes (most from Frank Yellin, fy@lucid.com).
-
- mips-pinsn.c:
- Print $ before register-names (I think that makes things a little
- more consistent).
- Never print two instructions, even if one delays.
- Removed hex-disassemble set_cmd. (This is not mips-specific,
- so I think the argument is whether it is generally worthwhile or not.
- I'm inclined to think not, given how easy it is to
- convert between radixes in gdb.)
-
- mipsread.c:
- This is basically Alessando's code.
- It doesn't use obstacks; I changed it to use obstacks
- in a few minor places where using malloc causes a
- memory leak. (Probably, more places could/should be changed.)
- I added record_misc_function where it was missing.
- In symbol_file_command and add_file_command, I tried
- to make the code consistent with more recent versions.
- Minor sylistic changes in parse_procedure.
- Make a .gdbinfo. psuedo-symbol point back to the real
- procedure symbol (using the isym field).
-
- mips-tdep.c:
- This is basically from my port, but with a lot of details
- and a number of routines merged in from Alessando's version.
- I basically used my code "raw" backtrace (use heuristics
- from the actual code, rather than symbol table info) - though
- the idea is Alessandro's. I feel my code is a little cleaner
- here, particularly in being a little more flexible, such as being
- able to handle gcc-produced code (which it now can).
- It also doesn't do frame caching (which is not useful
- more recent gdb versions).
- I also used my code for push_/pop_dummy, more or less.
- I tried to incorporate AF's code for testing sigtramp
- while backtracing; I probably got it wrong.
- Added mips_print_register, which tries to scrunch as much
- information as possible on a screen...
- Removed the skip-prologue set_cmd. As with hex-disassemble (see
- under mips-pinsn.c), I don't see anything mips-specific here,
- and I don't see it being all that useful anyway.
-
- tm-mips.h:
- Added a $fp psuedo-reg distinct from $fp (nice for gcc).
- Use more register names (rather than hard-cases numbers).
-
-Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
-
- * Hack up 3.90.11 changes:
-
- * Makefile.dist (depend): parameterize $(GCC).
- Add solib.c and solib.o.
- (readline): Fix vpath for both absolute or relative SRCDIR.
-
- * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
- Also, let the part I didn't understand at least compile so
- I can test the rest. FIXME.
-
- * dbxread.c: Fix thinko using strcmp.
- (init_psymbol_list): declare static.
- (partial_symbol_file_open): Comment cleanups better, avoid
- cleaning up the string table since the caller will do that.
- Move the stat for mod time into symbol_file_command, temporarily.
- (There should be a mod time for each symbol file, eventually,
- to control its rereading. FIXME.)
-
- * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
- SunOS, which gives error for shared libs otherwise. (From
- Schaefer, probably FIXME needs work for portability.)
-
- * solib.c: Move #include "param.h" to work.
- Lowercase all the Uppercase Letters In the Messages.
- (find_solib): Clean up inferior_so_name for debug printouts.
- Allow no argument, to mean all shared libraries.
-
- * symmisc.c: include param.h to get CLEAR_SOLIB.
-

-
- * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
- VPATH to readline.
- config.gdb: If srcdir != ., create readline directory and
- copy a makefile into it.
-
- * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
- consistency with POSIX.
-
- * breakpoint.c (bpstat_stop_status): Disable watchpoint
- when we exit its exp_valid_block.
-
-Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
-
- * Makefile.dist: Bump version to 3.91.3.
-
- * Clean up handling of breakpoint commands (somewhat).
- Prompted by Tiemann bug report "cont 10" doesn't work any more.
-
- inferior.h: Add breakpoint_proceeded to inferior status struct
- and globals; save it and restore it.
- (clear_breakpoint_commands): Cleanup, remove old #define.
-
- infrun.c (clear_proceed_status): Set breakpoint_proceeded.
- (save_inferior_status, restore_inferior_status): handle it also.
- (proceed): Remove earlier code that set breakpoint_proceeded.
- It is now set only in clear_proceed_status.
- (clear_proceed_status): Cleanup, use bpstat_clear rather
- than clear_breakpoint_commands. No callers need the stop_bpstat
- between clear_proceed_status and proceed.
-
- infcmd.c: Add breakpoint_proceeded definition and comment.
- (cont_command, jump_command, signal_command): Move call to
- clear_proceed_status right next to call to proceed.
-
- breakpoint.c (bpstat_do_actions): Avoid clobbering our
- caller's argument while running down the chain of breakpoints.
- Use new variable "breakpoint_proceeded" to determine when
- a command that it executes moves the inferior past the
- breakpoint.
- (bpstat_clear): Handle NULL argument.
- (bpstat_clear_actions): Avoid useless call to
- breakpoint_auto_delete.
- (delete_breakpoint): Clean up bpstat's that are pointing to
- the deleted breakpoint from the stop_bpstat chain.
- (breakpoint_auto_delete): Simplify.
-
- * Clean up handling of EOF, error on stdin, etc. This was
- prompted by a network problem that caused gdb to go into an
- infinite loop filling up its malloc'd memory.
-
- main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
- not clear_breakpoints_commands, which is now gone.
- (main): If command_loop returns (e.g. from EOF on stdin), do
- a quit_command (looping back to command_loop if quit_command
- doesn't really quit).
- (command_loop): check result from command_line_input and
- exit if it returns NULL, rather than passing the NULL to
- execute_command.
- (gdb_readline): Free malloc'd result space before returning
- NULL for EOF.
-
- * utils.c (query): Handle C-d to mean "yes", just as if the
- input was not a terminal. Also avoid infinite loop if EOF
- occurs in mid-input-line before newline. This allows
- query to be used at EOF on stdin with reasonable results.
-
- * infrun.c (proceed): Set breakpoint_proceeded.
-
- * values.c (value_as_long): Avoid infinite recursion for enums.
- (_initialize_values): Fix typo in help msg (kingdon).
-
- * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
- RL_LIB for linking. This allows -lreadline for linking
- and nothing for dependencies, once readline is a real library.
-
- * config.gdb: Jim Kingdon: give useful error message if the
- host or target type is not recognized.
-
- * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
- it just defines it. Dumb, but deal with it.
-
- * Jim Kingdon suggests:
- in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
-
-Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
-
- * Makefile.dist (VERSION): Bump version # to 3.91.2.
-
- * Clean up Bothner's changes.
-
- * blockframe.c (clear_pc_function_cache): New function.
- * blockframe.c: remake cache_pc_function_* static.
- * dbxread.c (symbol_file_command): remove references to
- cache_pc_function_* variables.
- * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
- * printcmd.c: Avoid kludging a global variable (addressprint)
- to avoid printing the address of a string twice. Instead,
- pass the format letter 's' down low enough that it can be seen
- to avoid this problem.
- (print_formatted): Pass format arg to value_print.
- (restore_addressprint): Remove function.
- (do_examine): Avoid hacking addressprint, cleanups and such.
- (print_frame_args): Add a comment to a Bothner change.
- * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
- * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
- to wipe out the values cached in blockframe.c.
- * symtab.c (find_method): Add comment saying how big you must
- allocate to be "big enough". Per being terse again.
- * valprint.c (val_print): Handle format letter "s" to print
- strings without addresses. Add comment to vtbl printing code
- which casts with wild abandon. Rearrange reference-printing
- code so it prints:
- @0xaddr: value (print w/addressprint)
- value (print w/~addressprint)
- @0xaddr (parameter lists w/addressprint)
- or nothing (parameter lists w/o addressprint)
-
-Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
-
- * Merge more changes from Per Bothner:
-
-Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
-annoying) that I tried to improve it. Here are my suggestions.
-
- These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
-
- findvar.c:
- Do automatic de-reference when taking the address of a reference.
- printcmd.c:
- Don't deref_ref when printing parameter lists.
- valops.c:
- More attempts at treating refernences properly.
- valprint.c:
- In val_print, if deref_ref==0, don't print dangling " = ".
- value.h:
- Add COERCE_REF macro, which de-references an REF.
-
- * Merge changes from Per Bothner:
-
-* Fixed (Sony news)-specific configuration problems.
-* Fixed other problems with using vanilla pcc and libc (enum problems;
-assumption that vsprintf exists).
-* Some major speed-ups (finc_pc_partial_function now caches a match;
-parsing avoids duplicate symbol_lookup calls).
-* Changed handling of baseclasses (no longer use baseclasses field
-of struct type, use the first n_baseclasses fields instead).
-* Various minor changes/fixes, most C++-related.
-
-blockframe.c:
-Cache the most previous match from find_pc_partial_function.
-(Save both low and high ends of matching function's pc range.)
-This speeds up the loop of infrun.c:wait_for_inferior quite
-a bit, and makes step/next commands much zippier.
-command.c:
-Added an enum->int cast (otherwise, some compilers barf).
-dbxread.c:
-No longer set baseclass offset to 0, since multiple
-inheritance now mostly works.
-Added a number of casts, to shut up compiler warnings
-(after stabs where made enums, not ints).
-When discarding a symbol table (in symbol_file_command),
-must clear the cache introduced in blockframe.c.
-Don't convert $vtbl_ptr_type to vtbl any more.
-Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
-Mask off sign bit emitted by g++ for virtual table offset.
-Set voffset to -1 (not 1) for static member functions.
-expread.y:
-Changed parsing/lexing of names to avoid doing symbol lookup twice
-(once when lexing to determine symbol class, once for real).
-Now only call symbol_lookup once. Fields of 'this' win especially big.
-printcmd.c:
-Subpress printing addr twice in the case of 'x/s addr'.
-symtab.c:
-lookup_basetype_type is no longer used.
-Add find_methods as recursive helper function to decode_line_1.
-This allows multiple inheritance to work.
-Also, once one or more matches has been found, do not look in
-base-classes. (Baseclass methods would be overridden, anyway.)
-symtab.h:
-Removed baseclasses array in struct type.
-Instead of using baseclasses[i], use fields[i-1].
-Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
-Changed sign convention of voffset (previous was inconsistent).
-tm-news.h:
-Some macros (CALL_DUMMY and relatives) were missing. Put them back.
-utils.c:
-Used to assume existence of vsprintf. Re-written to not need it
-if HAVE_VPRINTF is undefined.
-valops.c:
-typecmp was too pessimistic. Made it less so.
-valprint.c:
-Don't print space after address.
-If vtable points to a misc symbol (with 0 offset), print it,
-since that indicates the actual class of the object.
-Changed ype_print_derivation_info to use new inheritance
-scheme (without baseclasses vector).
-values.c:
-In value_primitive_field, fixed some bugs left over from previous set of fixes.
-Also, changes needed because TYPE_BASECLASSES were removed.
-xm-news.h:
-REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
-
-Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
-
- * source.c:
- If there is no path set, and the symbols don't indicate what directory
- a file was compiled in, look in the current directory. But either
- a path or a known compilation directory will prevent this.
-
- * dbxread.c:
- Three independent bug fixes:
- * Remove the #if 0 block that breaks some stuff.
- * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
- adapt gdb to either SunOS 4.0.* or 4.1.
- * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
-
- * symtab.c:
- Instantiate the class T when looking for methods in it. (Tiemann@sun)
-
- * valprint.c:
- (type_print) Demangle the name being printed.
- (type_print_base) Handle botched demangling without coredump (tiemann).
-
- * values.c:
- (check_stub_method): Document routine.
- (tiemann) fix bug for no-arg functions
- Avoid clobbering beyond end of malloc'd storage.
- Terminate the argument list properly.
-
-Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
-
- * Changes merged by John Gilmore:
-
-breakpoint.c:
- In breakpoint_1, use new print_address_symbolic instead
- of find_pc_partial_function. (This forces use of assembler-level
- addresses, and avoids misleading non-mangled source-level names.)
-cplus-dem.c:
- Generalize ansi argument such that -1 means skip arglist totally.
- Removed global variable print_ansi_qualifiers (which made
- code non-reentrant), in favor of extra explicit arguments
- to internal routines.
-printcmd.c:
- Add new helper function print_address_symbolic.
- Use find_pc_misc_function instead of find_pc_partial_function
- (since we want assembler-level symbols here).
-stack.c:
- Print unknown function as just "f (...)", not "f (...) (...)".
- Use new fputs_demangled explicitly.
-symtab.c:
- Fixed a typing violation (problem: value.h cannot be imported
- without renaming many variable in this file).
- lookup_symbol: If no matching misc_func, look for a C++-mangled name.
- decode_line_1: Moved forward some never-reached code.
- Made decode_line_2 skip function prologues correctly.
-utils.c:
- fputs_filtered should not demangle by default.
- Add new fputs_demangled to demangle on demand..
-valops.c:
- Change value_struct_elt to use value_primitive_field (using recursive
- utility function search_struct_field). This allows foo.bar to work
- for multiple inheritance (so far only for data fields).
- Change check_field in the same way (recursive helper function
- to support multiple inheritance).
- (Note: there are more of these problems that I haven't fixed.
- Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
- value_of_this: 'this' symbol name is now just "this", note "$this".
-valprint.c:
- Don't print static members.
- Avoid printing "members of <type>" if there are none.
- Simplified type_print_derivation_info by merging duplicate code.
- Remove useless blank lines in type_print_base (ptype command).
-value.h:
- Added declaration of new routine value_primitive_field.
-values.c:
- Added value_primitive_field which is generalized version of
- value_field that can handle multiple inheritance (non-zero offsets etc).
- Re-implemented value_field to call value_primitive_field.
-
-Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
-
- * infcmd.c -- insert else to avoid 'delete env' coredump when you
- delete the whole environment. Karl Berry reported the bug.
- * source.c - fix openp to avoid //'s in filenames, which
- trigger an Emacs bug causing it to not be able to find files
- when running gdb in a window.
- * dbxread.c - zap the #if 0 that botches the add-file code.
- It seems to work a lot better without all the code commented out.
-
-Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
-
- * Merge Tiemann's and Ted Goldstein's changes, detailed below,
- into gdb-3.90.9.
-
-Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
-
- * Makefile - added a ${CFLAGS} to a couple of entries,
- added remote-sa.sparc.c
- * added remote.sa-sparc.c, a modification of remote.c
- which conducts a dialog directly with the SparcStation prom.
- * breakpoint.c, infrun.c, sparcdep.c added
- remote_insert_breakpoint(), and remote_remove_breakpoint()
- to breakpoint.c instead of directly writing breakpoint instructions.
- * sparcdep.c on remote_debugging,there is no need
- to remove signle step breakpoint instructions.
- * main.c added "-epoch" flag and "int epoch_interface" to main.c
- global variable
- * printcmd.c - epoch interface sends lisp expressions to open up
- epoch windows on inspection.
- * valprint.c - added arrayprint, and addressprint and made adding
- format controls easier
- * wait.h added a couple of undef's because we were getting
- complaints about WSTOPSIG and WTERMSIG begin redefined.
-
-
-Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)

-Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
-
- * values.c (baseclass_addr): Run loop from INDEX+1 to

- @@ This should be restructured to use a cleaner search strategy.
-
-Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
-

-Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
-
- * symtab.c (list_symbols): add ability to set breakpoints on all
- the functions which match a particular regular expression.
-
-Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
-
- * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
- should print ANSI qualifiers (such as `const' and `volatile').
- All callers changed to call with ANSI == 1, except from
- `check_method_stub', which uses old-style syntax.
-
- * symseg.h (struct fn_field): Remove unneccessary `args' field.
- * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
-
- * values.c (check_stub_method): New function.
-
- * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
-
- * dbxread.c (read_type): Handle new GNU C++ method type stubs.
- * valprint (type_print_base): Ditto.
-
- * symtab.c (gdb_mangle_typename): New function.
-
-Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
-
- * breakpoint.c (catch_command): New function. Provides a
- mechanism to set breakpoints based on catch clauses.
- (disable_catch): Similar, but disables breakpoints on catch
- clauses.
- (delete_catch): Similar, but deleted breakpoints on catch clauses.
-
-Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
-
- * blockframe.c (blockvector_for_pc): New function.
- * blockframe.c (block_for_pc): Changed to call
- `blockvector_for_pc' and get the block itself.
-
- * stack.c (catch_info): New function. Prints info about
- exceptions which can be caught in the current frame.
- * stack.c (print_frame_label_vars): New function. Similar to
- `print_frame_local_vars'.
- * stack.c (print_block_frame_labels): Prints out labels that are
- defined in this frame. These labels are exceptions that can be
- caught.
-
- * dbxread.c: Updated to handle N_CATCH symtab types.
-
-Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
-
- * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
- form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
- when printing the type.
-
-Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
-
- * valprint.c (val_print): Use `baseclass_addr' to access the
- baseclasses pointed to via the derived class object at VALADDR.
-
- * values.c (baseclass_addr): New function. Casts derived pointers
- to baseclass pointers taking virtual baseclasses and multiple
- inheritance into account.
-
-Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-
- * Version 3.90.9.
-
-Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-
- * breakpoint.c (watch_command, bpstat_stop_status): Deal with
- exp_valid_block field correctly.
-
- * infrun.c (wait_for_inferior): When checking "don't even think
- about breakpoints" if stop_signal == SIGTRAP && trap_expected,
- also check step_resume_breakpoint.
- Insert breakpoints and continue (not step) if
- step_resume_break_address != NULL, even if another_trap.
- If trap_expected and we enter sigtramp, then set up a
- step_resume_break.
- If trap_expected is set when we hit the step_resume_break,
- set another_trap.
- When calling resume and trap_expected says tell resume to step
- (2 places), also check step_resume_break_address.
-
- * infrun.c (wait_for_inferior): Don't set
- prev_{pc,sp,func_{start,name}} before calling wait ().
- Do set them after exiting loop.
- Move their declarations outside functions.
- (start_inferior): Initialize them.
-
-Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-
- * infrun.c (wait_for_inferior, after check for trap_expected > 1):
- Restore old code which distinguishes between trap_expected and
- running_in_shell, just make the latter take any non-TRAP signal,
- not just SEGV.
-
- * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
-
- * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
- xconfig/3b1 (CC,PINSN_CC): Define.
-
- * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
-
