* config/tc-mips.c (hilo_interlocks): Change definition
so that MIPS32, MIPS64 and later ISAs are included, along with
the already-included machines. Update comments.
* gas/mips/relax-swap1.s: Add extra space at end, so the
disassembly will consistently have "..." at its end.
* gas/mips/relax-swap2.s: Likewise.
* gas/mips/relax-swap1-mips2.d: Expect "..." at end of disassembly.
Add opaque declarations.
(sparc64nbsd_sigcontext_saved_regs): New prototype.
* sparc64nbsd-tdep.c (sparc64nbsd_sigcontext_saved_regs): New
function with code split out from
sparc64nbsd_sigcontext_frame_cache.
(sparc64nbsd_sigcontext_frame_cache): Use
sparc64nbsd_sigcontext_saved_regs.
(_initialize_sparc64nbsd_tdep): Don't register OS ABI handler for
OpenBSD.
* sparc64obsd-tdep.c: New file.
* Makefile.in (ALLDEPFILES): Add sparc64obsd-tdep.c.
(sparc64obsd-tdep.o): New dependency.
* configure.tgt (sparc64-*-openbsd*): Set gdb_target to obsd64 and
gdb_osabi to GDB_OSABI_OPENBSD_ELF.
* config/sparc/obsd64.mt: New file.
* lib/compiler.c: Add hp_cc_compiler and hp_aCC_compiler.
* lib/compiler.cc: Likewise.
* lib/gdb.exp (get_compiler_info): Always call gdb_compile to
get the right preprocessor. Eval the output directly. Remove
special tests for hp_cc_compiler and hp_aCC_compiler. Remove
hp_f77_compiler and hp_f90_compiler completely.
(gdb_preprocess): Delete.
(get_compiler): Delete.
Patch for PR c++/1520:
* dwarf2read.c (read_func_scope): Set processing_current_prefix
properly if we have a specification die.
(determine_prefix_aux): Rename from determine_prefix.
(determine_prefix): Like the old determine_prefix, but never
returns NULL.
(RELAX_FIRST, RELAX_SECOND): Turn into 8-bit quantities.
(RELAX_USE_SECOND): Bump to 0x10000.
(RELAX_SECOND_LONGER, RELAX_NOMACRO, RELAX_DELAY_SLOT): New flags.
(mips_macro_warning): New variable.
(md_assemble): Wrap macro expansion in macro_start() and macro_end().
(s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Likewise.
(relax_close_frag): Set mips_macro_warning.first_frag. Adjust use
of RELAX_ENCODE.
(append_insn): Update mips_macro_warning.sizes.
(macro_start, macro_warning, macro_end): New functions.
(macro_build): Don't emit warnings here.
(macro_build_lui, md_estimate_size_before_relax): ...or here.
(md_convert_frag): Check for cases where one macro alternative
needs a warning and the other doesn't. Emit a warning if the
longer sequence was chosen.
* config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
the first sequence, the size of the second sequence, and a flag
that says whether we should warn.
(RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
(RELAX_FIRST, RELAX_SECOND): New.
(mips_relax): New variable.
(relax_close_frag, relax_start, relax_switch, relax_end): New fns.
(append_insn): Remove "place" argument. Use mips_relax.sequence
rather than "place" to check whether we're expanding the second
alternative of a relaxable macro. Remove redundant check for
branch relaxation. If generating a normal insn, and there
is not enough room in the current frag, call relax_close_frag()
to close it. Update mips_relax.sizes[]. Emit fixups for the
second version of a relaxable macro. Record the first relaxable
fixup in mips_relax. Remove tc_gen_reloc workaround.
(macro_build): Remove all uses of "place". Use mips_relax.sequence
in the same way as in append_insn.
(mips16_macro_build): Remove "place" argument.
(macro_build_lui): As for macro_build. Don't drop the add_symbol
when generating the second version of a relaxable macro.
(load_got_offset, add_got_offset): New functions.
(load_address, macro): Use new relaxation machinery. Remove
tc_gen_reloc workarounds.
(md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
version of a relaxable macro is needed. Return -RELAX_SECOND if the
first version is needed.
(tc_gen_reloc): Remove relaxation handling.
(md_convert_frag): Go through the fixups for a relaxable macro and
mark those that belong to the unneeded alternative as done. If the
second alternative is needed, adjust the fixup addresses to account
for the deleted first alternative.
testsuite/
* gas/mips/elf-rel19.[sd]: New test.
* gas/mips/mips.exp: Run it.
* dwarf2read.c (psymtab_to_symtab_1): Calculate lowpc, highpc via
get_scope_pc_bounds.
(read_file_scope): Ditto.
(get_scope_pc_bounds): New function, produced by extracting code
from the above two functions, consolidating it, and adding support
for DW_TAG_namespace.
