Add two pointers (saved_regs, extra_info) to struct frame_info.
Introduce new macro FRAME_INIT_SAVED_REGS which replaces
FRAME_FIND_SAVED_REGS.
Document.
Use in mn10300 and rs6000 targets. Fix side effects on ALPHA, MIPS,
Z8K and SPARC targets.
* config/xm-aix4.h (SIGWINCH_HANDLER): Function `aix_resize_window'
must accept a signal number as parameter.
* config/rs6000/xm-rs6000.h (SIGWINCH_HANDLER): Ditto.
* utils.c (initialize_utils): Give a parameter to `SIGWINCH_HANDLER'.
* inferior.h (register_valid): Variable's type is `SIGNED char', not
`char'.
* findvar.c (register_valid): Ditto.
* defs.h (make_cleanup_func): Protect parameter list by `PARAMS'.
* gdbthread.h (unbind_target_thread_vector): Likewise.
the stack frame. Their offset from the previous stack frame is in
fdata.gpr_offset and fdata.fpr_offset, not fdata.offset.
(gdb.base/return.exp)
* config/rs6000/tm-rs6000.h: Doc fixes.
* configure.in, configure: Recognize rs6000-*-aix4*.
* config/powerpc/xm-aix.h: Reduce to include "xm-aix4.h".
* config/rs6000/aix4.mh (XM_FILE): Point to xm-aix4.h.
* config/rs6000/xm-aix4.h: New file.
* config/xm-aix4.h: New file.
From the Mentor work...enable configure & build on rs6000-ibm-aix4.1.*.
Note this is an unbelievably buggy debugger on this host.
* config/rs6000/xm-rs6000.h (FIVE_ARG_PTRACE): Likewise.
So we can build under aix4 with an ansi compiler (should not effect aix3
since aix3 doesn't have a ptrace prototype).
of aix4 need different handling than aix3.
* configure: Updated.
* config/powerpc/{aix4.mh,aix4.mt,tm-ppc-aix4.h}: New files
specific to aix4 support on the power pc.
* config/powerpc/tm-ppc-aix.h (DONT_RELOCATE_SYMFILE_OBJFILE): Do
not defined. The aix4 specific target files will do that.
* config/rs6000/{aix4,mh,aix4,mt,tm-rs6000-aix4.h}: New files
specific to aix4 support on the rs6000.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR): Don't
do the conversion if the pointer is not a magic aix function
pointer.
* rs6000-tdep.c: Include objfiles.h and symtab.h.
(is_magic_function_pointer): New function.
* rs6000-tdep.c (skip_prologue): Refine check for frameless
functions. Handle b .+4 emitted by aix4 compilers. Only
allow one load of a minimal toc pointer. Handle aix4 compiler's
code for alloca.
* rs6000-tdep.c (find_toc_address): Report an error if no toc was
found rather than possibly core dumping.
* partial-stab.h: Handle extra field generated by the aix4 compiler
for enumerations.
* stabsread.c (read_enum_type): Likewise.
Don't test for zero backchain pointer to recognize a signal
handler frame, if read() gets interrupted by a signal, the
backchain will be non zero.
(SIG_FRAME_FP_OFFSET): Move to here from rs6000-tdep.c,
improve comment.
(SIG_FRAME_PC_OFFSET): New definition.
(FRAME_SAVED_PC): Return saved pc from sigcontext if this
is a signal handler frame.
* rs6000-tdep.c (function_frame_info): Do not error out
if we can't access the instructions.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR):
New definition to get the function address from a function pointer.
* valops.c (find_function_addr): Use it when calling a user
function through a function pointer.
(symfile.h, objfiles.h, xcoffsolib.h): Include.
(vmap): New global variable.
(exec_close): Close and free objects in vmap chain.
(exec_file_command) [IBM6000_TARGET]: Set up initial vmap.
(bfdsec_to_vmap, map_vmap): Moved here from xcoffexec.c.
(exec_files_info): Print vmap information.
* xcoffexec.c: Remove.
* config/rs6000/rs6000.mt, config/rs6000/rs6000lynx.mt
(TDEPFILES): Use exec.o instead of xcoffexec.o.
* TODO: Remove pertinent items.
BROKEN_LARGE_ALLOCA. Do the cleanup before returning, rather than
leaving it on the chain. Reindent much of this function.
* config/sparc/{xm-sun4sol2.h,xm-sun4os4.h},
config/i386/{xm-sun386.h,xm-i386m3.h,xm-i386mach.h},
config/m68k/{sun3os4.h,xm-news.h,xm-hp300hpux.h},
config/ns32k/xm-ns32km3.h: Remove all references to
BROKEN_LARGE_ALLOCA; with the above change it is no longer needed.
* main.c, fork-child.c, many config files: Remove all
SET_STACK_LIMIT_HUGE code; with the above changes it should no
longer be needed.
* symtab.c (lookup_partial_symbol): Use if and abort, not assert.
This avoids __eprintf troubles.
* main.c (main): Surround in #ifndef MAIN_OVERRIDE. Move
initialization code which needs to be called even if we bypass the
command line stuff into gdb_init.
* utils.c (fputs_unfiltered): Surround in #ifndef
FPUTS_UNFILTERED_OVERRIDE.
* Makefile.in (libgdb.a): New target.
* utils.c: Rearrange I/O stuff a bit so that all output goes
through fputs_unfiltered. Use vasprintf; removes arbitrary limit
which made %s not work with arbitrarily large strings.
* printcmd.c (printf_command): Use printf_filtered, not
printf_unfiltered and printf, now that arbitrary limit is gone.
config/gould/tmp-{pn,np1}.h,
config/{sparc/tm-sparc.h,pyr/tm-pyr.h,vax/tm-vax.h}: Remove field
next_frame from struct frame_info. It has no purpose beyond
->next->frame and is an artifact from GDB 2.8.
* signals.h: Don't undefine signals anymore.
* main.c: Use job_control from serial.h.
* fork-child.c (fork_inferior): Use gdb_setpgid.
* serial.h, ser-unix.c, ser-go32.c: Provide gdb_setpgid.
* utils.c (quit): Use current_target->to_terminal_ours to figure
out whether we care about lack of job control, rather than __GO32__.
* utils.c: Include serial.h not terminal.h
(quit): Use job_control not TIOCGPGRP.
* terminal.h: Don't undefine TIOCGPGRP.
* serial.h, ser-unix.c, ser-go32.c, ser-tcp.c: Add SERIAL_FLUSH_OUTPUT.

* serial.h: Add SERIAL_UN_FDOPEN.
* utils.c (quit): Use it.
* ser-unix.c: Add process group to ttystate.
[HAVE_SGTTY]: Add tchars, ltchars, and lmode to ttystate.
* inflow.c: Include serial.h not terminal.h.
Use serial.h stuff to replace most of the maze of #ifdef's.
* inflow.c, main.c, inferior.h: make gdb_has_a_terminal a function.
* serial.h: Document SERIAL_SET_TTY_STATE as being immediate.
* ser-unix.c: Use TIOCSETN not TIOCSETP so it is true.
* serial.h, ser-unix.c, ser-go32.c, ser-tcp.c:
Add SERIAL_PRINT_TTY_STATE, SERIAL_NOFLUSH_SET_TTY_STATE, and
SERIAL_SET_PROCESS_GROUP.
* inflow.c: Use them.
* config/xm-svr4.h, config/rs6000/xm-rs6000.h, config/sparc/sun4os4.h:
Define HAVE_TERMIOS.
* Various: Remove all use of TIOC*_BROKEN.
* command.c (do_setshow_command): Use %u with var_{u,z}integer.
* command.{c,h}: New var_type var_integer.
main.c: Use it for history_size.
* rs6000-tdep.c, xcoffexec.c, config/rs6000/xm-rs6000.h, breakpoint.c:
Lint and byte-order fixups.
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
get linked to nm.h, xm.h, and tm.h respectively by configure,
moved to appropriate config/<cpu> subdirectory.
