the step range test. Replace call detection test with much
simpler (and more efficient) test that doesn't require prologue
examination (as often).
* symtab.c symtab.h (in_prologue): New function that indicates
whether or not we are in a function prologue. This uses the
symbol table, and then falls back to prologue examination if that
fails. It's much more efficient for remote debugging because it
avoids examining memory, which is very slow. This is used in
wait_for_inferior to determine if we've made a function call that
needs to be skipped over (for next/nexti).
* mips-tdep.c (after_prologue): New function, returns the PC
after the prologue. Uses PDRs and the symbol table.
(mips_find_saved_regs): Use in_prologue() to avoid costly
prologue examination if possible.
(mips_skip_prologue): Use after_prologue() if possible to avoid
costly prologue examination.
Do not set saved registers from heuristics for a sigtramp frame.
* dwarfread.c (enum_type): Determine signedness of enum type
from enumerators.
* mips-tdep.c: Include gdb_string.h, gcc -Wall lint.
* rs6000-nat.c (xcoff_relocate_core): Fix typo.
* valops.c (value_repeat): Fix length of memory transfer to
match recent allocate_repeat_value change.
build config.h, add empty definitions to mk.tmp.
(powerpc-apple-macos): Make it work.
* mpw-make.sed: New file, sed commands to translate Unix makefile
into MPW syntax.
* mpw-make.in: Remove.
* mac-gdb.r: New file, was macgdb.r, renamed for consistency
with other tools, now includes cfrg resource.
* macgdb.r: Remove.
* config/m68k/xm-mpw.h: Remove most of contents, replace with
include of include/mpw/mpw.h.
* winsup. New directory.
* Makefile.in: Build winsup.
* configure.in: Winsup is configured when target is win32.
Can only build win32 target GDB when native.
* coff-i386.c (coff_i386_reloc_type_lookup): New.
* coffcode.h (coff_write_object_contents): If .bss is before
.data us that as data_start.
* cofflink.c (_bfd_coff_generic_relocate_section): Get reloc
calc correct.
* peicode.h (add_data_entry): Use _cooked_size of data directory.
(coff_swap_outhdr_out): Hardwire in version number.
* frags.c (frags): Variable deleted.
(frag_alloc): New function.
(frag_grow, frag_more, frag_variant, frag_now_fix, frag_append_1_char): Refer
to frchain_now->frch_obstack instead of frags variable.
(frag_new): Ditto. Verify that frch_last and frag_now match on entry and exit,
and that old frag_now has non-zero type. Replace "know" uses with "assert".
Use frag_alloc instead of mucking with obstack alignment.
* frags.h (frags): Declaration deleted.
* subsegs.h (struct frchain): Add new field frch_frag_now.
* subsegs.c (frchains, dummy_frag, absolute_frchain): New static variables.
(subsegs_begin): Initialize frchains obstack. Under gcc, don't give it any
stricter alignment than frchainS structures need. Do not initialize frags
obstack. Set frag_now to point to dummy_obstack. Initialize absolute_frchain.
(subseg_set_rest): Save and restore frag_now in frch_frag_now field of
frchainS. Don't create new frags on section switch, and use frag_alloc when
creating a new frag chain. For absolute section, set frchain_now to
absolute_frchain. Verify that frch_last and frag_now match on entry and exit.
Initialize per-chain obstack, and under gcc, set required alignment to that
needed by fragS structure.
* write.c (chain_frchains_together_1): Verify fr_type is nonzero.
In one test case of Mike's (i386-linux, over 300K lines of .s code with lots
of stabs records), run time and memory use are reduced by about 1/3.
Might introduce some problems in cases that use the frag obstacks in unusual
ways. Test suite does pass for i386-linux and sparc-solaris targets though.
now relative to the section, not absolute.
* ecofflink.c (_bfd_ecoff_locate_line): Use the right symbol to
get the file name when there is a N_SO directory name. When
handling stabs, remember that section->vma was added to the
offset.
