	* symtab.c (find_main_psymtab):  Add FIXME comment.

Wed Sep 16 22:31:55 1992  K. Richard Pixley  ([e-mail])

	* breakpoint.c, sparc-tdep.c: comment changes.
	* configure.in: removed target_dependent line.

	* remote-mm.c (mm_attach): change printf to error to prevent
	fallthrough bug.

	* rs6000-tdep.c (push_dummy_frame, pop_dummy_frame): replace
	calls to {fetch|store}_inferior_registers with calls to
	target_{fetch|store}_registers, for remote-target independence.

Sat Sep 19 04:23:54 1992  John Gilmore  ([e-mail])

	* Makefile.in:  Fix bug I introduced in merging Rich's change.
	* infrun.c (child_create_inferior):  Use proceed() rather than
	doing all the same stuff by hand.

Thu Sep 17 17:35:37 1992  K. Richard Pixley  ([e-mail])

	* Makefile.in, configure.in: add support for files used only when
	configured native, that is, when host = target.

Wed Sep 16 23:03:23 1992  K. Richard Pixley  ([e-mail])

	* tm-sparc.h, xm-sparc.h: externs and macros relating to deferred
	stores are target dependent and were moved from xm to tm.

Sat Sep 19 03:14:37 1992  John Gilmore  ([e-mail])

	* Makefile.in (gdb-all.texi):  Build in objdir, not $srcdir.

	* config/decstation.mh:  Add MMALLOC_LIB and MMALLOC_DISABLE
	overrides, to avoid problem in xdr_bytes with malloc(0) => 0.

Wed Sep 16 20:04:54 1992  K. Richard Pixley  ([e-mail])

	* target.h (struct target_ops):  removed to_convert_to_virtual and
	to_convert_from_virtual elements.  Initializations removed from
	all static initializations.
	(target_convert_to_virtual, target_convert_from_virtual):
	removed.
	(host_convert_to_virtual, host_convert_from_virtual):  Removed
	forward declarations.
	* target.c (cleanup_target): removed default assignments for
	to_convert_to_virtual and to_convert_from_virtual.
	* inftarg.c (host_convert_to_virtual, host_convert_from_virtual):
	removed.

Fri Sep 18 02:07:39 1992  John Gilmore  ([e-mail])

	* main.c (gdb_readline):  Avoid printf_filtered, which sets char
	position wrong if used for the prompt.
	* utils.c (puts_filtered):  Comment:  NOT a puts() replacement!

	Support for accessing arbitrary MIPS stack frames in memory.

	* blockframe.c (get_prev_frame_info):  If INIT_FRAME_PC_FIRST is
	set, run it before INIT_EXTRA_FRAME_INFO.
	* stack.c (frame_info):  If PRINT_EXTRA_FRAME_INFO defined, call it.

	* mips-tdep.c (init_extra_frame_info): Only clobber the `frame'
	(FP) value in the frame_info struct if it is zero (as from top of
	execution stack).
	(setup_arbitrary_frame):  Implement FRAME_SPECIFICATION_DYADIC.

	* mips-xdep.c (fetch_inferior_registers):  ZERO_REGNUM always
	comes back as zero.  So does FP_REGNUM, as a trigger for
	init_extra_frame_info.

	* tm-mips.h (INIT_FRAME_PC_FIRST):  Kludge, FIXME, defined to get
	the program counter set before INIT_EXTRA_FRAME_INFO is run.
	(INIT_FRAME_PC):  Defined to null.
	(PRINT_EXTRA_FRAME_INFO): print frame pointer location via symtab.
	(FRAME_SPECIFICATION_DYADIC):  Ask for two args in frame command.
	Briefly explain MIPS stacks in GDB.

Thu Sep 17 03:49:59 1992  John Gilmore  ([e-mail])

	* copying.awk, copying.c (show_copying_command,
	show_warranty_command):  Rename from copying_info, warranty_info,
	to match command function conventions.

	* utils.c (prompt_for_continue):  Reinitialize more-counts
	before printing anything, and again afterward.  Fix comments.
	(vfprintf_filtered):  Eliminate static buffer; use auto buffer,
	or alloca() if needed.

	* rs6000-xdep.c:  Use correct conditional (IBM6000_TARGET) to
	detect native versus cross-host.

Wed Sep 16 21:57:14 1992  Stu Grossman  (grossman at cygnus.com)

	* m68k-tdep.c (sun3_saved_pc_after_call):  Only do trap check for
	Suns.  Rename to m68k_saved_pc_after_call.
	* tm-68k-noun.h, tm-sun3.h (SAVED_PC_AFTER_CALL):  Use
	m68k_saved... instead of sun3_saved...

Wed Sep 16 17:00:07 1992  John Gilmore  ([e-mail])

	* Makefile.in (update-depend, update-alldeps): Split out of
	setup-to-dist, for convenience in rebuilding the depend and
	alldeps.mak files.
	(assorted):  Update to catch straggler files when building gdb.tar.Z.

Tue Sep 15 01:18:50 1992  John Gilmore  ([e-mail])

	Preliminary cleanup for splitting host/native/target.

	* infptrace.c (child_resume):  Don't deal with NO_SINGLE_STEP
	here; it is dealt with at a gdb-target-independent level.
	* rs6000-tdep.c (single_step):  Don't call ptrace, we are a
	high toned routine.  Fix return type to void.
	* tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.
	Rich and I believe the "real problem" was that both single_step
	and target_resume were issuing PT_CONTINUE calls.  This would
	cause the second PT_CONTINUE to sometimes fail because the process
	was already running.
	* infptrace.c (child_resume):  Remove AIX_BUGGY_PTRACE_CALL kludge.

Mon Sep 14 19:20:43 1992  Stu Grossman  (grossman at cygnus.com)

	* procfs.c (proc_wait):  Call print_sys_errmsg() if we get an
	error from PIOCSWSTOP.

	* breakpoint.c, core.c, exec.c, language.c, main.c, printcmd.c,
	symfile.c, target.c, valprint.c:  Use _filtered form of *printf.
	defs.h, utils.c:  Make vfprintf_filtered global.

Fri Sep 11 18:28:28 1992  Roland H. Pesch  ([e-mail])

	* doc/gdb.texinfo, doc/gdbinv-m.m4.in, doc/gdbinv-s.m4.in: first
	pass at doc for new remote target--- Tandem
	ST2000 using STDBUG.

	* doc/all.m4, doc/none.m4: new m4 switch, _ST2000__

	* doc/all.m4: turn on H8/300 stuff for generic manual

	* doc/gdbinv-s.m4.in: remove text on special procedures to continue 
	after explicit call to breakpoint() in serial stubs.

Fri Sep 11 01:34:25 1992  John Gilmore  ([e-mail])

	* mipsread.c:  Clean up some white space.
	(parse_symbol):  Handle stEnd of stFile.

	* mips-xdep.c (REGISTER_PTRACE_ADDR, fetch_inferior_registers,
	store_inferior_registers):  Replace unexplained numbers
	with manifest constants from a DECstation header file.
	* xm-mips.h (KERNEL_U_ADDR):  Get from <machine/param.h>.
	(REGISTER_U_ADDR):  Fix up for Ultrix 4.2.

	* tm-tahoe.h, xm-tahoe.h (KERNEL_U_ADDR):  Move macro to xm-tahoe.h.

	* stack.c (_initialize_stack):  "dow" should be a valid abbreviation
	for "down".  Suggested by Richard Stallman.

Thu Sep 10 15:26:07 1992  Ken Raeburn  ([e-mail])

	* remote-vx.c: Rename realloc for inclusion of rpc/rpc.h, to avoid
	redeclaration bug on SunOS 4.

Wed Sep  9 17:36:53 1992  John Gilmore  ([e-mail])

	* i386-stub.c, sparc-stub.c (getpacket):  Actually check checksums.
	* m68k-stub.c:  Remove a few extraneous ANSI-isms.

	they aren't already there.
	* remote-vx.c (vx_prepare_to_store):  Ditto.
	* xcoffread.c:  Surround forward struct defns with #ifdef __STDC__.

Wed Sep  9 16:50:22 1992  John Gilmore  ([e-mail])

	Removed a large number of changes inserted by Per Bothner
	for C++ support.  These will go back in when they've been
	examined.

	(saber_gdb): Load opcodes library.

Tue Sep  8 15:22:06 1992  Stu Grossman  (grossman at cygnus.com)

	* a68v-xdep.c (store_inferior_registers):  declare as void.
	* infptrace.c:  HP/Apollos have ptrace.h in the wrong place.
	* remote-st2000.c:  Massive changes to use new serial package.
	Also added 'connect' command to transparantly connect to serial
	port.
	* ser-termios.c:  Big cleanup, use nicer coding conventions.
	* ser-bsd.c:  New module, serial stuff for BSD systems.
	* serial.h:  Define struct ttystate properly using HAVE_TERMIO.
	* xm-apollo68b.h:  #define PTRACE_IN_WRONG_PLACE...

Fri Sep  4 18:53:57 1992  Roland H. Pesch  ([e-mail])

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

	* symfile.h:  Declaration of set_demangling_style() moved
	here from demangle.h (which is now in ../include).

Thu Sep  3 13:44:46 1992  K. Richard Pixley  ([e-mail])

	* symtab.c (completion_list_add_symbol): restructured to optimize
	for time.  First clip names that cannot match.  Then clip any
	names we've already considered.  Drop a redundant strncpy.  Drop
	a redundant malloc and associated free for demangled names.

Thu Sep  3 09:17:05 1992  Stu Grossman  (grossman at cygnus.com)

	* configure.in:  Add host m68k-apollo*-bsd*.
	* demangle.c (struct demanglers):  Use enum instead of constant
	value to keep braindamaged HP/Apollo compiler happy.

Wed Sep  2 20:45:31 1992  Per Bothner  ([e-mail])

	* utils.c (strcmp_iw):  Add a hack to allow "FOO(ARGS)" to
	match "FOO".  This allows 'break Foo' to work when Foo is
	a mangled C++ function.  (See comment before function.)

Wed Sep  2 13:45:27 1992  John Gilmore  ([e-mail])

	* config/rs6000.mh (MH_CFLAGS):  Circumvent IBM <rpc/rpc.h> bug,
	for files in vx-share/*.c.
	* xm-rs6000.h (fd_set):  Circumvent the rs6000.mh circumvention,
	for normal GDB source files.

	* Makefile.in (VERSION):  Roll to 4.6.6.

	* infrun.c:  Lint for recent `handle' changes.

	* ser-termios.c, ser-go32.c:  Remove DEFUN crap, clean up.
	* serial.h (EXFUN):  Remove all uses, convert to PARAMS.
	* config/sun4os4.mh:  Include ser-termios.o.  FIXME, all .mh files
	should include a ser-XXX.o module.

	* dbxread.c (elfstab_build_psymtabs):  Remove DEFUN crap.
	* defs.h, i960-pinsn.c, remote-hms.c:  Replace CONST with simple const.

	* configure.in:  Map unrecognized sun 68k's, sun sparcs, into 
	known suns in configure.in, rather than mapping them to unique
	config files that happen to duplicate other config files.
	* config/sun3.{mh,mt}:  Remove (use identical sun3os4.*).
	* config/sun4.{mh,mt}:  Remove (use identical sun4os4.*).

Wed Sep  2 00:10:43 1992  John Gilmore  ([e-mail])

	* configure.in (*-*-sunos*):  Use trailing * to match all
	sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.
	(sparc-*-sunos3):  Remove host & target.  Sunos3 never shipped
	in production on Sun-4.

	(m68k-*-{aout,coff,elf}):  Add targets, w/new config and tm files.
	(sparc-*-{aout,coff,elf}):  Add targets, w/new config and tm files.

	* config/m68k-un.mt, config/m68k-noun.mt, config/sparc-un.mt,
	config/sparc-noun.mt:  New target configs for embedded.
	* config/sun4os3.{mh,mt}:  Remove, never existed in production.

	* tm-68k-un.h, tm-68k-noun.h, tm-spc-un.h, tm-spc-noun.h:  New
	target definitions for embedded with and without underlines on
	identifiers.  FIXME -- this ought to be known by BFD instead.

	* tm-sparc.h, tm-sun2.h, tm-sun3.h:  Delete NAMES_HAVE_UNDERSCORE:
	not a parameter of the CPU, but of the development environment.
	* tm-es1800.h, tm-sunos.h, tm-vx68.h:  Add NAMES_HAVE_UNDERSCORE.

Tue Sep  1 17:31:45 1992  John Gilmore  ([e-mail])

	* breakpoint.c (breakpoint_re_set):  Avoid setting source symtab
	(which involves reading in main's symtab) if we have no breakpoints.

Mon Aug 31 13:47:45 1992  Fred Fish  ([e-mail])

	* dwarfread.c (cu_language):  New local variable to record
	language for current compilation unit being processed.
