早期freebsd实现

	enumerations.
	* dwarfread.c (read_structure_scope):  Synthesize typedefs
	for C++ classes, structs and unions.
	* dwarfread.c (read_enumeration):  Synthesize typedefs for
	C++ enumerations.
	* dwarfread.c (read_file_scope):   Call set_cu_language to
	record language for current compilation unit.  After symtab
	is built, save this recorded language.
	* dwarfread.c (process_dies, add_partial_symbol, struct_type,
	scan_partial_symbols, new_symbol):  Recognize TAG_class_type.
	* dwarfread.c (add_partial_symbol):  Synthesize partial symbol
	typedefs for C++ classes, structs, unions, and enumerations.
	* dwarfread.c (scan_compilation_units):  Call set_cu_language
	to record language for current compilation unit.	
	* dwarfread.c (scan_partial_symbols):  Call add_enum_psymbol here
	for TAG_enumeration_types, rather than in add_partial_symbol.
	* dwarfread.c (add_partial_symbol):  Combine TAG_enumeration_type
	case with class, struct, and union type cases, now that they are
	the same.  Remove tests for non-NULL name attributes, now done
	by callers.
	* gdbtypes.h (TYPE_CODE_CLASS):  Add type for C++ classes, but
	treat as alias for TYPE_CODE_STRUCT for now.

	* Makefile.in: map "gdb" through program_transform_name when
	installing.

Sun Aug 30 21:18:51 1992  Fred Fish  ([e-mail])

	* {i386-tdep.c, m68k-tdep.c, mips-tdep.c, sparc-tdep.c}
	  (supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
	Use "regi" for local indexing through register numbers, reserving
	"regno" for the name of a specific register passed as an input
	parameter.  Fix bug propagated through all versions that sometimes
	used regno as an index when it should have been regi, thus using
	-1 as an index in some cases.

Sun Aug 30 18:15:17 1992  Per Bothner  ([e-mail])

	* cplus-dem.c, demangle.h:  Moved to ../libiberty and ../include,
	respectively, so same demangler can be used by other programs.
	* Makefile.in:  Remove demangler stuff.
	* Makefile.in (depend):  Pass -I../readline (needed for main.c).
	* demangle.c (_initialize_demangler):  Tell demangler which
	CPLUS_MARKER to assume.

Wed Aug 26 16:02:01 1992  Fred Fish  ([e-mail])

	* cplus-dem.c:  Reorder args to most local functions to make them
	follow the consistent pattern of struct work_stuff pointer first,
	followed by pointer into string being demangled, followed by
	pointer to the string where the result is being stored, followed
	by other args.  Also generally replace most variables of name
	"type" with "mangled" for consistency.  They all pointed to the
	same string but half were one name and half the other.
	* cplus-dem.c (LONGERNAMES):  Remove #ifndef's.
	* cplus-dem.c (demangle_qualified):  Rewrite to clean up and allow
	use whenever a qualified name is being demangled.
	* cplus-dem.c (do_type):  Qualified names are treated similarly
	to fundamental types, not as modifiers of fundamental types.

	numbers, signal number ranges, and to recognize "all" to mean all
	signals except those used by the debugger.
	* infrun.c (SET_SIGS, UNSET_SIGS):  Macros used in handle_command
	to set or reset actions for specific signals.

Sun Aug 23 17:10:07 1992  Fred Fish  ([e-mail])

	* coffread.c (decode_type):  Call alloc_type to alloc new
	types.
	* stabsread.c (read_array_type, read_range_type, define_symbol):
	Call alloc_type to alloc new types.

	coff_read_enum_type):  Use TYPE_ALLOC.
	* dwarfread.c (struct_type):  Use TYPE_ALLOC.

	allocate_cplus_struct_type):  Use TYPE_ALLOC.
	* mipsread.c (parse_symbol, parse_type):  Use TYPE_ALLOC.
	* stabsread.c (read_struct_type, read_array_type, read_enum_type,
	read_range_type):  Use TYPE_ALLOC.

	* breakpoint.c (breakpoint_re_set):  Select a default source
	symtab if one is not currently selected.
	* utils.c (query):  Call wrap_here before building the output
	query string, to turn off wrapping and flush any buffered output.
	Otherwise our query may end up in the wrap buffer and never be
	seen by the user.
	* eval.c (evaluate_subexp):  Report error when attempting to
	evaluate subscript for types without a target type, rather
	than dumping core by using the NULL pointer.
	* symfile.c (symbol_file_command):  Forget current_source_symtab
	and current_source_line when discarding symbol table.

Sat Aug 22 22:33:20 1992  John Gilmore  ([e-mail])

	make all this re-entrant by storing all state on the stack.  Clean
	up memory error trapping.  (computeSignal, set_debug_traps):
	make it all table driven.  Make a start at a baud rate setting command.

	<rpc/svc.h> on RS/6000.

Tue Aug 18 14:48:24 1992  Ian Lance Taylor  ([e-mail])

 	* Makefile.in: added FLAGS_TO_PASS variable, and passed it to
	recursive invocations of make.  Always create installation
	directories.

Mon Aug 17 18:29:58 1992  Per Bothner  ([e-mail])

	* m68k-pinsn.c:  Minor fix in style of output (don't use

	deal with arbitrary registers.  Needed for sparc-stub.

Fri Aug 14 12:11:25 1992  Fred Fish  ([e-mail])

	* cplus-dem.c (cplus_markers):  Add table for gnu style and

	* cplus-dem.c (cfront_special):  New function, as suggested
	by [e-mail].
	* cplus-dem.c (forget_types):  New function.
	* cplus-dem.c (cplus_demangle):  Call gnu_special, moved from
	demangle_prefix().
	* cplus-dem.c (mop_up):  Call forget_types().
	* cplus-dem.c (AUTO_DEMANGLING, GNU_DEMANGLING, LUCID_DEMANGLING):
	Use throughout, instead of checking current_demangling_style.
	* cplus-dem.c (demangle_signature):  When finding an explicit
	start of function args, forget all remembered types for
	lucid/cfront style demangling.
	* cplus-dem.c (demangle_prefix):  In a sequence of two or more
	underbar characters, use last pair as the delimiter.  Hoist
	gnu_special() call up to cplus_demangle().  Call cfront_special()
	when appropriate.
	* cplus-dem.c (cplus_special):  Fix virtual table name demangling
	for inherited classes.	
	* cplus-dem.c (demangle_args):  Document quirks of numbered
	references to previously seen types.
	* dbxread.c (read_ofile_symtab, process_one_symbol):
	Use AUTO_DEMANGLING rather than explicitly checking
	current_demangling_style.
	* demangle.h:  Add some comments.

	CFRONT_DEMANGLING):  New macros.
	* dwarfread.c (LCC_PRODUCER):  Remove trailing space, which is
	not found in the actual producer string produced by lcc.
	* dwarfread.c (handle_producer):  Use AUTO_DEMANGLING rather

	* breakpoint.c (enable_longjmp_breakpoint,
	disable_longjmp_breakpoint, set_longjmp_resume_breakpoint):
	Check for duplicate breakpoints at the same address.  Bug report
	and preliminary fix from Dave Morrison, <[e-mail]>.

Wed Aug 12 11:14:58 1992  Fred Fish  ([e-mail])

	* buildsym.c (end_symtab):  Document that end_symtab can return
	NULL under non-error conditions.
	* dwarfread.c (read_file_scope):  Guard against dereferencing NULL
	returned from end_symtab for empty compilation units.

	* am29k-tdep.c:  Lint from DECstation compiler.
	* mem-break.c:  Restore test of BREAKPOINT size that Fred removed.
	As the man page says, "Sometimes you just can't get lint to shut
	up".  That doesn't mean you should blow away the code it won't
	shut up about.
	* mips-xdep.c:  Revise stubbing-out of code until Rich cleans
	it up over the next few weeks.  Make mips x 29k build.
	* tm-29k.h (CALL_DUMMY):  Make it work on cross-endian hosts.
	(FIX_CALL_DUMMY):  Comment in the patching of the breakpoint,
	but leave it as a comment because the breakpoint instruction 
	is not easily accessible at this moment (it's static, and if
	we define one here, it goes into every file compiled).

Mon Aug 10 22:27:19 1992  Fred Fish  ([e-mail])

	* Makefile.in (VERSION):  Bump to 4.6.3.
	* dwarfread.c (scan_partial_symbols):  Skip over DIE's within

	an AT_byte_size attribute is seen.
	* mipsread.c (psymtab_to_symtab_1):  Fix misspelled cast to
	union aux_ext (was aux_ent).
	* i386-pinsn.c (print_insn):  Cast 2'nd arg to read_memory from
	unsigned char* to char*, for Lucid compiler.
	*
