gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
Actually, just pick up a couple of files that I forgot.
* defs.h: Reword confusing comment about ANSI prototypes.
* defs.h: Some minor whitespace changes.
* infrun.c (wait_for_inferior): Compare int tmp to int 0,
not NULL, which can be (void *).

* xm-sysv4.h: Back out of change for missing prototypes.
* i386-tdep.c (get_longjmp_target): Add function.
* 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.)
a ptype to reflect the setting of TARGET_PTR_BIT. Set the
TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
* tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
* printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
it before printing out the hex shape of an address.
functions for which no definitions or prototypes are provided in
any currently included gdb or host environment header files.
For SVR4, this currently includes malloc and realloc, which cannot
be portably prototyped in any gdb include file.
size, and use throughout. Round buffer size up if too many regs.
Support baud rate setting and try for an 8-bit path. If
interrupted while waiting for target, send a ^C down the wire.
Avoid single-byte reads.
* tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
and NUM_REGS.
* mips-xdep.h: Avoid the embedded regs when on Unix.
all-breakpoints' command.
* (get_number): Allow users to enter negative breakpoint numbers.
* (breakpoint_1): Reformat display of 'info break' to show new
fields.
* (create_longjmp_breakpoint, breakpoint_re_set,
breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
symfile.c (syms_from_objfile): Re-do
insertion of longjmp breakpoints. Move all code into
breakpoint_re_set, and call that instead of
create_longjmp_breakpoint in symfile.c.
* breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
* symtab.c (find_pc_symtab): Handle having no objfiles.

* breakpoint.c, infrun.c: Lint.
* printcmd.c: Use `enum enable' rather than `enum
display_status'.
* mipsread.c: First pass at making it compile with the new
objfile changes. Probably seriously broken still, but it
compiles. FIXME.
breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
stepping (and nexting) through longjmp(). Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.
Makefile.in: Update version to 4.4.3
* minsyms.c (install_minimal_symbols): Add bunches to any
existing minsyms in the objfile. Avoid extra mallocation
by working directly in the obstack. Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c: Change all callers.
* FIXME: We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.
* valops.c, value.h: Lint.
* remote-vx.c: Add missing break; statement. Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.
to make prototypes for all functions declared here.

* m2-exp.y: Remove unused CONST; Rename OR and AND.
* utils.c: Avoid declaring malloc and realloc. Lint.
(request_quit): Accept signal-number parameter.
symbol table and add symbol information to the misc function vector.
This allows minimum functionality with non -g compiled code, and is
vital for use with shared libraries (non of which are currently
compiled with -g).
Note to anyone doing any SVR4/gdb work. This bug was introduced into
gdb just prior to the gdb 4.4 release, thus any versions currently
in the field will have broken shared library support since no symbol
information at all will be available for the shared library. This
fix, along with one about to go into bfd's elf.c should fix that
problem.
between partial symbol tables (when not doing stabs-in-ecoff).
(This used to be handled by parse_fdr, but parse_fdr was
incompatible with handling stabs-in-ecoff, so the code
was re-written to not use parse_fdr. Unfortunately,
the logic to handle dependencies was overlooked.)
describing enum.
* defs.h: added new #define for TARGET_PTR_BIT, defaults to size
of target int.
* h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
* symtab.c (lookup_reference_type, lookup_ptr_type): use
TARGET_PTR_BIT to determine size of a pointer
* values.c (unpack_long): when unpacking a REF or a PTR don't
assume the size of the type.
* dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
offset to process_one_symbol.
(process_one_symbol): Take new offset parameter. Add it into
appropriate symbol types to relocate symbols to loaded addresses.
Handle all possible symbol types, and complain() about types that
we don't expect to see.
* mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
process_one_symbol (FIXME, should pass real offset).
Misc bugfixes:
* breakpoint.c (resolve_sal_pc): Split out code to resolve a
sal's PC value.
(set_breakpoint, break_command_1, until_break_command,
catch_command_1, breakpoint_re_set_one): Use it.
(breakpoint_re_set_one): Disable bkpts that don't re-set cleanly.
(breakpoint_re_set): Mention breakpoint number in error messages.
* symtab.h (resolve_sal_pc): Declare.

* source.c (find_source_lines): Avoid "Source file is more
recent than executable" when bfd_get_mtime gives 0.
(list_command): Shorten "FILE, line N" to "FILE:N".
* putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
* target.c (target_read_string): Create this routine to read null
terminated strings from the target. It deals with running off the
end of memory elegantly as well. solib.c (find_solib): Use
target_read_string() to avoid problems with running off the end of
memory.
to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
to reflect actual locations of opcode files, so TAGS target will
be buildable.
i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k code.
m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
dereferencing to access the correct elements.
valops.c (value_addr): Declare return type of external func value_copy().
xcoffread.c: Undefine next_symbol_text before redefining it.
command that prints /proc specific information, changes to solib.c to
allow more flexible handling of finding the dynamic linker structures,
changes to utils.c and defs.h to add a new null_cleanup() function to
serve as an anchor point for cleanup chains with no obvious "first
cleanup".
Made some more progress in removing duplicate assembly opcode files.
More improvements to how mipsread and to a lesser extent dbxread work.
See the ChangeLog for details.
causing return of random value to callee.
* config/mh-amix, config/mh-i386v4: Change to find alloca by
compiling and linking alloca.c, even when it is not strictly
required. Also arrange to link with -ltermlib rather than
-ltermcap.
* Makefile.in: Move TERMCAP definition to prior to inclusion
of host makefile fragments so it can be overridden.
Change svr4 references to sysv4.
* source.c: Move declaration of external function index to
front of file so it is in scope for all references.
* utils.c (error, fatal): Make definitions consistent with
defs.h declarations (declared as "volatile void").
to take into account the minimum size granularity of the code section. For
now, the buffering is simply disabled until it can be done right.
There is still a similar problem in the i386 disassembly code for locations
within 20 bytes of the end of the code segment.
* Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
added clean-info. added some standards.text support and made it
look like our other Makefiles.
* configure.in: mark this directory target dependent. configure
now runs entirely in objdir so make existence tests and
references against ${srcdir}.
Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.
* main.c (initialize_main): Revise command descriptions.
* command.c (show_user): `info user' -> `show user'.
* symtab.c (_initialize_symtab): Typo in `info types' desc.
* coffread.c (coff_symfile_read): Avoid select_source_symtab,
since it is not needed and can cause errors when examining ".o"s.
(read_coff_symtab, decode_base_type): Use complain, not printf.
Print symbol name, not its number.
Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
someday should go in a clipper target config file.
* symfile.c (compact_misc_function_vector): Handle empty vector.
(complain, clear_complaints, syms_from_objfile): Fix complaint
formatting.
* xcoffexec.c: Change syms_from_objfile caller.
in the same executable without collision (c-exp.y, m2-exp.y). Add forward
delaration of function returning pointer to shut up compiler warnings about
conversion of int to pointer (symtab.h).
core file (core.c), permanently remove the register_addr() stub (elfread.c),
move a misplaced #endif (procfs.c), and add fetch_core_registers func for
core file support (procfs.c).
READ_MIPS_FORMAT, which have been unused since BFD. Still
remaining is COFF_NO_LONG_FILE_NAMES.
* tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
function calling code moved to m68k-tdep.c.
Complain if no auxents on .bf and .ef FCN symbols, and assume
lots of line numbers.
(init_linenos, enter_linenos): Use a sentinel at the end of the
read-in linenos, to make for a fast, safe loop-end test.
* utils.c: All the v*fprintf emulation is now in libiberty,
so we can get rid of some junk.
* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
* m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
type operands, as used by branch instructions.
* gmalloc.c: Fix prototype of memcpy.
* elfread.c: Comment out register_addr, since it conflicts
with the one in coredep.c.
* buildsym.h: Remove extern declarations of two functions
that are really static in buildsym.c.
* tm-mips.h: Add symbolic names for more registers.
* mips-xdep.c (store_inferior_registers): Use new register names.
* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
only used for core files, not ptrace. Therefore,
the KERNEL_U_ADDR hack is no longer needed.
The mapping to ptrace number is now in in mips-xdep.c.
* mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
mapping from the old REGISTER_U_ADDR), and use it
in {fetch,store}_inferior_registers.
* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
Save/restore FP regs correctly (?).
* dbxread.c: Remove duplicate define_symbol and type_synonym_name
(these had been previously moved to buildsym.c).
Hence, define_symbol becomes extern instead of static.
* buildsym.c (read_struct_type): Comment out bogus handling
of C++ operator methods. Minor hacking of reading of class
contexts. Make define_symbol non-static, so dbxread.c can call it.
filename with error messages.
* stack.c (frame_select_command): Rename to select_frame_command
to avoid "fr" and "fra" having nonunique completions.
* symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
(symfile_init): Print file format name when unable to handle it.
(free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
* symmisc.c (free_symtab): Only free linetable if nonzero.
* symtab.h: Remove obsolete BLOCKLIST macros.
(record_line): Record directly in a subfile. Alloc on demand.
(compare_line_numbers): Add from xcoffread.c.
(end_symtab): New params say whether to sort pendings and
linetable. Patch block stabs if defined. Shrink linetable before
allocating the symtab.
* buildsym.h: Delete line_vector* and prev_line_number. Add
global_stabs and file_stabs for xcoffread.
* dbxread.c (start_subfile): Move to buildsym. Change above calls.
* symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
* symmisc.c, symtab.c: Cope with null LINETABLEs.
(add_symbol_file): Call it to do the real work.
(syms_from_bfd): Initialize entry_point before calling symfile_init.
* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
