Kung Hsu 70126bf94e Modified Files:
ChangeLog configure.in defs.h mips-tdep.c

        * configure.in: add mips64-*-elf, mips64-*-ecoff, mips64el-*-elf,
        mips64el-*-ecoff and mips64-big-*.
        * defs.h: get rid of FORCE_LONG_LONG.
        * mips-tdep.c (mips_find_saved_regs): add sd and sdc1 instruction
        parsing. Change register size to be MIPS_REGSIZE.
1994-02-18 01:38:08 +00:00
Peter Schauer 0434c1a0c9 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
alpha and irix. The _sigtramp case has to be handled properly
	in the tdep files if we have no ecoff debugging info.
	* alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
	mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
	without PC_REGNUM kludge.
	* mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
	Clean up handling of mips sigtramp frames, improve comments.
1994-01-31 16:23:48 +00:00
Peter Schauer 5efd597b3c * mips-tdep.c (init_extra_frame_info): Use frame relative stack
pointer value when fixing up the frame at the start of a function
1994-01-22 20:45:55 +00:00
Ian Lance Taylor e03c0cc670 Added Irix 5 support.
* configure.in (mips-sgi-irix5*): New host and target.  Use irix5
	for both.
	* config/mips/irix5.mh, config/mips/irix5.mt,
	config/mips/xm-irix5.h, config/mips/nm-irix5.h,
	config/mips/tm-irix5.h, irix5-nat.c: New files for Irix 5 support.
	* mdebugread.c: New file, split out of mipsread.c.  Added
	elfmdebug_build_psymtabs routine.  Added some checks on external
	symbols.  Changed code to keep ecoff_debug_info and
	ecoff_debug_swap structs in the psymtab and in global pointers
	rather than retrieving them from the bfd.  Also changed to keep
	the pending list with the psymtab rather than the objfile (each
	psymtab for a single objfile points to the same pending list).
	* mipsread.c: Bulk of file moved into mdebugread.c, leaving just
	the sym_fns.
	* Makefile.in (SFILES): Added mdebugread.c.
	(OBS): Added mdebugread.o.
	(mdebugread.o): New target.
	* symfile.h: Declare mdebug_build_psymtabs and
	elfmdebug_build_psymtabs.
	* elfread.c (struct elfinfo): Added mdebugsect field.
	(elf_locate_sections): Remember location of .mdebug section.
	(elf_symfile_read): Call elfmdebug_build_psymtabs on .mdebug
	section.
	* infrun.c (AT_FUNCTION_START): Set to 0 if not already defined.
	(wait_for_inferior): Use AT_FUNCTION_START if it is defined to see
	if PC is at the start of a function.
	* mips-tdep.c (read_next_frame_reg): Use SIGFRAME_REG_SIZE, and
	give it a default definition.
	(mips_skip_prologue): Skip instructions which initialize $gp
	register.
	(in_sigtramp): New procedure, moved in from mipsread.c.
	* config/mips/tm-mips.h: Declare in_sigtramp.
1993-12-06 17:31:05 +00:00
Jim Kingdon 002a422b22 * mips-tdep.c (init_extra_frame_info): Check to see whether the
registers mentioned in the proc_desc have been saved.  This
	generalizes mips_in_lenient_prologue in the sense that we keep
	searching until we've found saves for all the registers, not just
	look for a "lenient prologue" pattern.
	* mips-tdep.c: #if 0 lenient prologue code.

	* mips-tdep.c (heuristic_proc_desc): Don't assume a host short
	is 16 bits.
1993-11-12 16:35:59 +00:00
Thomas Lord 199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

	reported by benson@odi.com. Obviously Ultrix 4.3A cc now has
	the same problems as the OSF/1 alpha cc.
	* mipsread.c (parse_lines):  Iterate over the range of the compressed
	line number entries, the old iteration sometimes failed to stop
	and wrote past the end of the LINETABLE. Add sanity check to avoid
	the same problem in case the line number info is corrupt.
	* mipsread.c (parse_procedure):  Adjust pdr for alpha __sigtramp.
	* mipsread.c (parse_external, parse_partial_symbols):  Ignore stNil
	symbols that are produced for statics in .o files and stLocal symbols
	that are produced for every section in OSF/1 dynamically linked
	 executables.
	* mipsread.c (psymtab_to_symtab_1):  Put out `undefined symbols'
	warning only under `verbose on' as there are many undefined symbols
	in a dynamically linked executable.
1993-09-23 07:22:06 +00:00

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

* Update copyrights in all changed files.
* dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
solib.c, symtab.h, tm-umax.h, valprint.c:  Lint.
* tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,

John Gilmore 361bf6eee5 Minor bug fixes from BSD Net2 gdb:
* blockframe.c (get_prev_frame_info):  If FRAME_CHAIN_COMBINE
returns 0, there is no previous frame.
* breakpoint.c (commands_command):  If !from_tty, don't call
input_from_terminal_p().
* dbxread.c (record_misc_function):  Speed up slightly.
(compare_psymbols):  Ditto.
* infcmd.c (do_registers_info):  Take a second argument to
determine whether to print float registers.  "info registers"
does not do so anymore.  "info all-registers" does, now.
* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info):  Take second
arg and ignore it.
* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO):  Pass second arg.
* inflow.c (initialize_inflow):  Set tflags_ours correctly.
