早期freebsd实现

	* 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)

	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)

	it find the registers in the core-file header.
	* 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.

	other improvements, due to comments by Fran鏾is Pinard
	([e-mail]) 

	* doc/gdb.texinfo (appendix "Installing GDB"): changes in

	exact match.
	(echo_command):  Use printf_filtered, and force output out.

	* dbxread.c (read_enum_type):  Avoid Modula-2 kludge that breaks C
	programs.
	* i387-tdep.c (double_to_i387):  Fix typo for double_to_ieee_extended.

	* doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
	(nodes Continuing and Stepping; Memory; Targets) clarifications
	due to Larry Breed

Fri Oct 11 23:27:06 1991  John Gilmore  (gnu at cygnus.com)

	* tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h:  Move
	REGISTER_U_ADDR to corresponding xm- file.  Sugg. by Peter Schauer.

	* symmisc.c (print_partial_symtabs):  Add printpsyms debug cmd.

	* m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame):  Add
	generic routines for calling inferior functions.

	* blockframe.c (inside_main_scope, inside_entry_scope):  New.

	* copying.awk:  Filter formfeeds out of copying & warrantee.
	Make them available as `show copying' and `show warrantee' also.
	* main.c (print_gnu_advertisement):  Advt `show' commands.

Thu Oct 10 17:25:47 1991  John Gilmore  (gnu at cygnus.com)

	core-file reading code.
	* core.c (get_core_registers):  Avoid coredump if no .reg section.

Wed Oct  9 17:03:34 1991  John Gilmore  (gnu at cygnus.com)

	* mipsread.c, coffread.c:  initialise TYPE_VPTR_FIELDNO to -1.
	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.

	* 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>.

	write the (pseudo) FP.
	* mipsread.c (parse_partial_symbols):  Improved algorithm for
	setting pst->texthigh.

Fri Oct  4 16:47:32 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/Makefile: make TEXINPUTS include . everywhere

Fri Oct  4 00:35:56 1991  John Gilmore  (gnu at cygnus.com)

	* 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
	<[e-mail]>).

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
	until it is large enough.    

	* dbxread.c (read_type):  Handle error case slightly better.
	Make complaint message not C++-specific.

Wed Oct  2 17:21:07 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  Fix step/next so that you only
	stop at the beginning of a new line.  This fixes various problems
	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 <[e-mail]>.)

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.

	* coffread.c (coff_symfile_read):  Use xmalloc, not malloc.
	* core.c (core_files_info):  Shorten output.
	* exec.c (exec_files_info):  Ditto.
	(build_section_table):  Ignore zero-length sections.
	* language.c, printcmd.c:  Lint.
	* language.h (get_frame_language):  Declare.
	* saber.suppress:  update.
	* stack.c (find_relative_frame):  Remove complex code that was
	#if 0'd, stick with simple code.  Lint.
        * saber.suppress:  Update a bit.
	* symfile.c (add_symbol_file_command):  Add "?" to question.
	* utils.c (parse_escape):  Avoid \a due to bdead compilers.
	* value.h:  Declare typedef_print.

	* valprint.c (val_print, type_print_base):  TYPE_CODE_RANGE less
	kludgey.

	* nindy-tdep.c (nindy_frame_chain_valid):  Use lookup_misc_func.
	(Reported by Mark Peek <[e-mail]>.)

	* 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.

Tue Sep 24 18:05:30 1991  John Gilmore  (gnu at cygnus.com)

	* infrun.c (IN_SIGTRAMP):  Not parenthesized properly.
	Bugfix from Paul Eggert <[e-mail]>.

	GDB-4.1 release!

	* Makefile.in (VERSION):  Set to 4.1.	
	* language.c (set_language_command):  Print useful help message,
	and restore the language string after giving help.
	* valprint.c (typedef_print):  Print typedef in C or M2.
	* symtab.c (list_symbols):  Use it.
	* main.c (main):  Avoid any output before (gdb) prompt when -q.
	* language.c (set_language_command):  Handle errors by restoring
	the language string to its current state (fix from A. Beers).
	* doc/gdbint.texinfo:  Roll in information from README.  Rearrange
	"how to install" and "how to print the doc" stuff so it drops
	easier into README.
	* configure.in:  Rename rtpc CPU to romp to match config.sub.
	* README, WHATS.NEW, TODO:  Update for gdb-4.1.

Fri Sep 20 17:39:14 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/gdb.texinfo: Updates from ChangeLog.  set/show write, 
	autoloading shared libs, copyright etc on GDB startup, clean up $_
	and $__ index refs, set/show listsize and related updates to list
	cmd.  New host/target configs.

Fri Sep 20 15:46:00 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/Makefile: generate aux version-no file doc/gdbVN.m4
	from main Makefile.in version definition

	* doc/gdb.texinfo: merge new language-switching and lang-specific
	doc by Andrew Beers

Fri Sep 20 15:00:57 1991  Per Bothner  (bothner at cygnus.com)

	* mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
	compilers (which may lack stddef.h).

Fri Sep 20 13:29:42 1991  John Gilmore  (gnu at cygnus.com)

	* dbxread.c (read_dbx_symtab, process_one_symbol):  N_FN and
	N_WARNING are the same except for the N_EXT bit, so just use their
	values alone, rather than OR-ing them with N_EXT.

Fri Sep 20 12:27:55 1991  Stu Grossman  (grossman at cygnus.com)

	* mipsread.c (parse_lines):  Deal with negative extended line
	offsets correctly.

	* c-exp.y, m2-exp.y:  #define yyerrflag and yynerrs to avoid
	global symbol conflicts.

Fri Sep 20 02:28:15 1991  John Gilmore  (gnu at cygnus.com)

	* .gdbinit:  Move 'set complaints' to top, so it runs even in
	case we aren't debugging GDB.
	* language.c (_initialize_language):  Fix type check and range
	check documentation strings.
	* utils.c (!HAVE_VPRINTF):  Define vfprintf as a function, so
	language.c can use it.  (Though language.c should really not be
	handling warnings/errors the way it does, FIXME.)
	* symtab.c (lookup_primitive_type):  cons
