早期freebsd实现

	* core.c (core_command):  Make nicer error message for no core support.

	Lint around file_ptr's (bfd's off_t's) and bfd_seek.

	* dbxread.c (read_dbx_symtab):  Use L_SET as bfd_seek arg.
	(elfstab_build_psymtabs):  staboffset and stabstroffset args are
	file_ptr's.
	* dwarfread.c (struct dwfinfo):  Convert dbfoff, lnfoff to file_ptr.
	(scan_compilation_units):  Punt unused filename arg.  dbfoff,
	lnoffset, and curlnoffset are file_ptr's now.
	(dwarf_build_psymtabs):  Drop desc and filename args; use
	objfile.  dbfoff and lnoffset are file_ptr's now.
	(read_ofile_symtab):  foffset is now file_ptr.  Use L_SET in bfd_seek.
	* elfread.c (struct elfinfo):  dboffset and lnoffset are file_ptr's.
	(elf_symfile_read):  Skip desc and filename args to
	dwarf_build_psymtabs.  Pass file_ptr's to elfstab_build_psymtabs.
	* gdb-stabs.h:  Use file_ptr rather than off_t.
	* mipsread.c (fixup_symtab): f_ptr is a file_ptr.  Re-enable
	compile-time debug check that someone turned off as "unused".
	(read_the_mips_symtab):  st_filptr is a file_ptr.  Fix bfd_seek call.
	* symfile.h:  Update dwarf_build_psymtabs and
	elfstab_build_psymtabs prototypes.
	* xcoffread.c (init_stringtab, init_lineno, xcoff_symfile_read):
	Use file_ptr offsets.  bfd_seeks use L_SET.

	* mips-tdep.c, mipsread.c, tm-mips.h:  Get rid of ".gdbinfo."
	symbol.  #define MIPS_EFI_SYMBOL_NAME instead.  Use different
	value so that demangler won't be invoked.  This greatly speeds up
	stepping.
	* mips-tdep.c (mips_pop_frame):  Rewrite handling of
	linked_proc_info so that it properly deallocates the appropriate
	item after it is done with it instead of before.
	* Don't pass bogus frame pointer to create_new_frame().  Just
	leave it as zero so that lower level code will figure out the
	correct value.

Fri Sep  4 00:34:30 1992  Per Bothner  ([e-mail])

	A bunch of changes mostly to improve debugging of C++ programs.
	Specifically, the calling of inferiors methods is improved.

	* value.h:  New macros METHOD_PTR_IS_VIRTUAL,
	METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
	hide the implementation details of pointer-to-method objects.
	How to tell if the pointer points to a virtual method is
	still very dependent on the particular compiler, but this
	should make it easier to find the places to change.
	* eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
	(val_print [case TYPE_CODE_PTR]):  Use the new METHOD_PTR_*
	macros, instead of a hard-wired-in code that incorrectly
	assumed a no-longerused representation of pointer-to-method
	values.  And otherwise fix the relevant bit-rotted code.

	* valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
	If there are both fields and methods, put a space between.

	* stabsread.c (read_struct_type):  Fix bug in handling of
	GNU C++ anonymous type (indicated by CPLUS_MARKER followed
	by '_').  (It used to prematurely exit the loop reading in
	the fields, so it would think it should start reading
	methods while still in the fields.  This could crash gdb
	given a gcc that can emit nested type information.)

	* valops.c (search_struct_method):  Pass 'this' value by
	reference instead of by value.  This provides a more
	consistent interface through a recursive search where the
	"bottom" functions may need to adjust offsets (due to multiple
	inheritance).
	* valops.c, value.h, values.c:  Pass extra parameters to
	value_fn_field and value_virtual_fn_field so we can
	correctly adjust offset for multiple inheritance.
	* eval.c (evaluate_subexp [case OP_FUNCALL]):  Simplify
	virtual function calls by using value_virtual_fn_field().
	* values.c: New function baseclass_offset, derived from
	baseclass_addr (which perhaps can be made obsolete?).
	It returns an offset rather than an address.  This is a
	cleaner interface since it doesn't mess around allocating
	new values.
	* valops.c (search_struct_method):  Use baseclass_offset
	rather than baseclass_addr.

Mon Oct  5 16:02:04 1992  Stu Grossman  (grossman at cygnus.com)

	* tm-29k.h (DUMMY_FRAME_RSIZE):  Pad out to doubleword.

Mon Oct  5 09:46:44 1992  Ian Lance Taylor  ([e-mail])

	* munch: HP9000/300 nm puts an extra space between T and symbol
	name.

	* config/irix4.mh: added -lsun to XM_CLIBS to get RPC functions
	needed for vxworks targets.

Fri Oct  2 22:04:42 1992  John Gilmore  ([e-mail])

	* am29k-tdep.c (_initialize_29k):  Make it possible for the
	user to set and query the address where function calls into the
	inferior write a small scratch routine.  `set call_scratch_address'
	* inferior.h (PC_IN_CALL_DUMMY):  Fix fencepost error.
	* remote.c (remote_prepare_to_store): Only fetch regs if they are
	not already cached validly.

Thu Oct  1 14:36:42 1992  K. Richard Pixley  ([e-mail])
