+
+Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
+
+ * procfs.c: Move inclusion of defs.h to before param.h, as in

+
+ * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
+ skipping function prologues, ala the other cpu families (i386,

+
+ * source.c (open_source_file): If openp fails, try again
+ using just the base (non-directory) part of the filename.
+ This solves various annoying problems, such as when the
+ source was compiled with an absolute pathname - and the
+ source files have moved. Or if the source was compiled
+ using a relative pathname, it can be more convenient
+ to just specific the source directory to the dir command.

+ and condense_misc_bunches(), these are now done in elfread.c.
+
+ * elfread.c: Add support for reading bfd canonical symbol tables
+ and generating misc function vector entries for global and
+ absolute symbols. Do calls to init_misc_bunches() and
+ condense_misc_bunches() where they will enclose all calls to
+ record_misc_function(), including those in dwarfread.c.
+
+Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)

+
+ Allow setting breakpoints on C++ destructors.
+ * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

+ * eval.c (parse_and_eval_type), value.h: New function,
+ parse_and_eval_type, is based on old code from check_stub_method.
+ But don't actually evaluate the cast, since that calls
+ value_cast(), whcih may fail. Just extract the type
+ from the parsed expression.
+ * values.c (check_stub_method): While looping through the
+ arguments, adjust depth *after* parameter has been handled.
+ Replace call and setup of parse_and_eval with new function
+ parse_and_eval_type.
+
+Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)

+ Add tracking of object files (that contain symbols) to gdb.
+ This includes a "struct objfile" that owns symtabs and psymtabs
+ that were read in from that binary file.
+
+ * symfile.h: Add struct objfile. Add pointer to the objfile
+ into the struct sym_fns.

+Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
+
+ * Makefile.in: link with libiberty after libreadline, since
+ readline might want something in libiberty.
+ * m88k-xdep.c: Fixed the register offsets in the ptrace_user
+ struct for BCS 88k machines.
+ * xm-m88k.h: don't define USIZE if already defined.

+
+Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
+
+ * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.

+
+ * coffread.c (read_coff_symtab): coffread used to rely on the
+ x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
+ function. Two of the formats I'm using (29k and 88k) don't seem to
+ set it. Ths patch to fcn_last_line and (enter_linenos) is an
+ attempt to use the actual size of the linno table in the file to set
+ the number of linenos to process.
+
+Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
+
+ * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and

+ * 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
+ allocating the symtab.
+ * buildsym.h: Delete line_vector* and prev_line_number. Add
+ global_stabs and file_stabs for xcoffread.
+ * dbxread.c (start_subfile): Move to buildsym. Change above calls.
+ * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
+ * symmisc.c, symtab.c: Cope with null LINETABLEs.
+
+ * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
+ * 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.
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
* 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.
