* Projects: Patching executables is done.

[deliverable/binutils-gdb.git] / gdb / ChangeLog

Fri Jan 31 00:05:01 1992  John Gilmore  (gnu at cygnus.com)

	* Projects:  Patching executables is done.
	* Makefile.in (VERSION):  Roll to gdb-4.4.
	* README:  Update for gdb-4.4.

	* symfile.c (reread_symbols):  Whenever we reread one object
	file's symbols, we must restart the scan, because the object_files
	chain has been permuted.

	* exec.c (exec_files_info):  Split out into print_section_info.
	Print BFD filename of each section if it's not the default one.
	* core.c (core_files_info):  Call print_section_info.

	* xm-vax.h:  Include a few system header files whose definitions
	must precede defs.h.
	* language.c, language.h:  Make some things const.
	* expression.h, main.c:  const spreads like ooze.

	* mem-break.c (break_insn, break_insn_size):  Use unsigned chars,
	since BREAKPOINT values can be >0x80.

Thu Jan 30 17:21:14 1992  Stu Grossman  (grossman at cygnus.com)

	* infrun.c, xm-i386sco.h:  SCO needs to use setpgid().

Thu Jan 30 01:04:23 1992  John Gilmore  (gnu at cygnus.com)

	* sparc-pinsn.c:  Remove kludge for preferring architectures.
	Remove #ifdef's for SORT_NEEDED.  We need to sort the table, now
	and forever.  Add `add' instruction to the set that get checked
	for a preceding `sethi' in order to print an absolute address.
	Corresponding changes in ../include/opcode/sparc.h needed
	to eliminate garbage instructions.

Wed Jan 29 19:24:34 1992  Per Bothner  (bothner at cygnus.com)

	* mipsread.c (parse_partial_symbols):  Make sure partial
	symbols are created for external symbols (as used to be
	the case).  This is a bit of a pain with the mips-coff.
	It uses a table which points to all of the external
	symbols belonging to a particular FDR or psymtab.
	Once we've generated this table, we might as well save
	it, and then use it in psymtab_to_symtab_1 to find
	the symbols to pass to parse_external().
	* symfile.c,  symfile.c:  New function start_psymtab_common
	to share the common parts of allocating a new psymtab
	for dbxread, mipsread (and later dwarfread).  Its code
	was pulled out from start_psymtab in dbxread.c.
	* dbxread.c (start_psymtab):  Use start_psymtab_common().

	* valprint.c (val_print):  If there is an error when trying
	to print a string, check to see if there really is a problem
	by reading just one character.  If that works, assume
	things are ok.

Wed Jan 29 18:58:43 1992  Stu Grossman  (grossman at cygnus.com)

	* sparc-pinsn.c (compare_opcodes):  Make it prefer v6, v7,
	cypress, v8 mnemonics in that order.

Tue Jan 28 17:32:13 1992  Per Bothner  (bothner at cygnus.com)

	* sparc-pinsn.c:  Put the qsort() back in.

Mon Jan 27 18:51:03 1992  John Gilmore  (gnu at cygnus.com)

	* findvar.c (read_register, write_register):  Handle machines
	where REGISTER_TYPE is not the same size as "int".

	Handle debug symbols in dynamically loaded (relocated) code:

	* dbxread.c (read_ofile_symtab):  Fix up N_CATCH better.  Pass
	offset to process_one_symbol.
	(process_one_symbol):  Take new offset parameter.  Add it into
	appropriate symbol types to relocate symbols to loaded addresses.
	Handle all possible symbol types, and complain() about types that
	we don't expect to see.
	* mipsread.c (psymtab_to_symtab_1):  Pass offset of zero to
	process_one_symbol (FIXME, should pass real offset).

	Misc bugfixes:

	* breakpoint.c (resolve_sal_pc):  Split out code to resolve a
	sal's PC value.
	(set_breakpoint, break_command_1, until_break_command,
	catch_command_1, breakpoint_re_set_one):  Use it.
	(breakpoint_re_set_one):  Disable bkpts that don't re-set cleanly.
	(breakpoint_re_set):  Mention breakpoint number in error messages.
	* symtab.h (resolve_sal_pc):  Declare.
	* infcmd.c (jump_command):  Use resolve_sal_pc.

	* source.c (find_source_lines):  Avoid "Source file is more
	recent than executable" when bfd_get_mtime gives 0.
	(list_command):  Shorten "FILE, line N" to "FILE:N".

	* putenv.c (putenv):  Avoid unportably casting pointers to unsigneds.

	* buildsym.c (read_struct_type):  Circumvent sun3 sunos "--"
	compiler bug.

	* c-exp.y (yylex):  `this' and `template' are only tokens in C++.

	* target.c (target_xfer_memory):  Return errno in preference to EIO.

	* 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.

Mon Jan 27 15:46:21 1992  Stu Grossman  (grossman at cygnus.com)

	* dbxread.c (process_one_symbol):  Make a first cut at handling
	symbol tables generated by Sun's acc.  (#ifdef'd out, FIXME.)

	* symtab.c (find_pc_line):  Fix stepping into and out of #included
	files.

Mon Jan 27 13:00:55 1992  Stu Grossman  (grossman at cygnus.com)

	* Makefile.in (OPCODES):  Remove OPCODES defs and refs.  There is
	no longer any need to copy ../include/opcode/* into gdb.

Mon Jan 27 12:30:38 1992  John Gilmore  (gnu at cygnus.com)

	* ChangeLog, ChangeLog-9091:  Split ChangeLog at 1992.

	from current maintainer (Peggy Fieland).

Sun Jan 26 19:05:40 1992  Per Bothner  (bothner at cygnus.com)

	* valprint.c (type_print_base, type_print_method_args):
	Print C++ constructor methods without bogus "return type."

Sat Jan 25 15:57:59 1992  Fred Fish  (fnf at cygnus.com)

	* infptrace.c (child_xfer_memory):  Parameter "target" should
	be a pointer to a structure, not the entire structure.

Fri Jan 24 01:30:27 1992  Fred Fish  (fnf at cygnus.com)

	* depend:  Convert the couple of references to ansidecl.h that
	used the local gdb version to use the ../include version.

Thu Jan 23 22:24:43 1992  Fred Fish  (fnf at cygnus.com)

	* 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.

	* i386-tdep.c (i386_frame_num_args):  Takes a pointer to a struct
	not the entire struct itself.

	* valops.c (value_assign):  Cast some args to modify_field() and
	{read,write}_register_bytes() correctly.

	* ansidecl.h:  Removed, is duplicate of ../include/ansidecl.h

	* Makefile.in (MALLOCSRC):  Removed reference to removed local
	copy of ansidecl.h.

	scope.

Mon Jan 20 19:06:28 1992  Stu Grossman  (grossman at cygnus.com)

	* main.c (main):  Make option_index local to keep new getopt happy.
	main.c, solib.c, Makefile.in:  Update copyright notices.

Mon Jan 20 08:54:00 1992  Michael Tiemann  (tiemann at cygnus.com)

	values that are computed off a base register.

	* dwarfread.c (new_symbol):  Rework TAG_global_variable and
	TAG_local_variable cases to account for static variables
	within function scopes.

Tue Jan 14 12:28:52 1992  Stu Grossman  (grossman at cygnus.com)

	* inflow.c:  remove #include <sys/dir.h>.  Not necessary, and
	doesn't exist on some systems.

	* infrun.c (wait_for_inferior!!!!):  Prevent gdb from hanging when
	nexting over recursive function calls.

	* 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.

	* inflow.c (child_terminal_info):  #ifdef TIOCPGRP around lines
	that reference pgrp_inferior.

Mon Jan 13 14:57:11 1992  Per Bothner  (bothner at cygnus.com)

	* tm-mips.h:  Removed BLOCK_ADDRESS_ABSOLUTE, now that
	mips-tfile has been hacked to act more "traditionally."

	freescope, buildblock closescope, record_line, add_symbol_to_list,
	gatherblocks, make_blockvector):  Extensive changes to switch
	to generic symbol table building code in buildsym.c.  Remove
	scope tree structures and functions, symbol table building
	functions, and lots of other small changes.

	* dwarfread.c:  Add new macros GCC_PRODUCER and STREQN.  Remove
	GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.

Tue Jan  7 13:09:57 1992  Stu Grossman  (grossman at cygnus.com)

	* i386-tdep.c (supply_fpregset, fill_fpregset):  Remove m68k
	code.

	* m68k-tdep.c (supply_fpregset, fill_fpregset):  Fix array
	dereferencing to access the correct elements.

	* valops.c (value_addr):  Declare return type of external func
	value_copy().
