Based on patch from Daniel Berlin <dberlin@dberlin.org>.
* buildsym.c: Include "demangle.h" for SYMBOL_INIT_DEMANGLED_NAME.
(finish_block) For non-function blocks, hash the symbol table. For
function blocks, mark the symbol table as unhashed.
* minsyms.c (msymbol_hash): Return hash value without taking modulus.
(msymbol_hash_iw): Likewise.
(add_minsym_to_hash_table): Take modulus of msymbol_hash's return
value.
(add_minsym_to_demangled_hash_table): Likewise for msymbol_hash_iw.
(lookup_minimal_symbol): Likewise for both.
* symtab.h (struct block): Add `hashtable' flag. Comment the
hashtable.
(BLOCK_HASHTABLE, BLOCK_BUCKETS, BLOCK_BUCKET): New macro.
(ALL_BLOCK_SYMBOLS): Update.
(BLOCK_SHOULD_SORT): Do not sort hashed blocks.
(struct symbol): Add `hash_next' pointer.
* symtab.c (lookup_block_symbol): Search using the hash table when
possible.
(find_pc_sect_symtab): Use ALL_BLOCK_SYMBOLS.
(search_symbols, find_addr_symbol): Likewise.
* dstread.c (process_dst_block): Clear hashtable bit for new block.
(read_dst_symtab): Likewise.
* jv-lang.c (get_java_class_symtab): Likewise.
* mdebugread.c: Include "gdb_assert.h".
(shrink_block): Assert that the block being modified is not hashed.
* coffread.c (patch_opaque_types): Use ALL_BLOCK_SYMBOLS.
* symmisc.c (free_symtab_block): Walk the hash table when freeing
symbols.
(dump_symtab): Recognize hashed blocks.
* printcmd.c (print_frame_args): Assert that function blocks do not
have hashed symbol tables.
* ada-lang.c (symtab_for_sym): Use ALL_BLOCK_SYMBOLS.
(fill_in_ada_prototype, debug_print_block): Likewise.
(ada_add_block_symbols): Use ALL_BLOCK_SYMBOLS. Handle hash tables.
(ppc_cpu): Make it unsigned long to agree with struct powerpc_opcode
flags.
(ppc_size): Delete.
(ppc_xcoff64): Rename to ppc_obj64.
(md_parse_option <m>): Encode old ppc_size value in ppc_cpu.
(ppc_set_cpu): Set PPC_OPCODE_32 too.
(ppc_arch): Use ppc_obj64 instead of ppc_size to select bfd_mach_ppc64
or bfd_mach_ppc.
(ppc_target_format): Use ppc_obj64 to select format.
(md_begin): Adjust for PPC_OPCODE_32/64 in ppc_cpu.
(ppc_insert_operand): Use ppc_obj64 instead of ppc_size.
(ppc_elf_suffix): Likewise. Don't depend on BFD_DEFAULT_TARGET_SIZE.
(tc_frob_symbol): Likewise.
(md_assemble): Use ppc_obj64 instead of ppc_size. Don't depend on
BFD_DEFAULT_TARGET_SIZE.
(ppc_tc): Likewise.
(ppc_is_toc_sym): Likewise.
(md_apply_fix3): Likewise.
* config/tc-ppc.h (TC_FORCE_RELOCATION): Don't depend on
BFD_DEFAULT_TARGET_SIZE.
(ELF_TC_SPECIAL_SECTIONS): Likewise.
(tc_frob_symbol): Likewise.
(ppc64_elf_howto_table): Use ONES here to avoid warnings. Fill in
missing src_mask fields. Tweak R_PPC64_NONE, R_PPC64_COPY. Fill
in missing dst_mask fields on R_PPC64_PLT32, R_PPC64_PLTREL32.
(mips_ip): Likewise.
* mips.h (INSN_MIPS16): New define.
* mips-dis.c (mips_isa_type): Add MIPS16 insn handling.
* mips-opc.c (I16): New define.
(mips_builtin_opcodes): Make jalx an I16 insn.
NULL sym_hashes to just before use.
<case R_CRIS_32_GOTREL>: In test for local symbol, accept also
symbol with non-default visibility.
<case R_CRIS_32_GOTREL, case R_CRIS_32_PLT_GOTREL>: Ditto.
<case R_CRIS_8_PCREL, case R_CRIS_16_PCREL, case R_CRIS_32_PCREL>:
Ditto.
(cris_elf_gc_sweep_hook): Only decrease h->plt.refcount for
symbol with non-default visibility.
(cris_elf_check_relocs): At tests for local symbol before
increasing h->plt.refcount, also check for non-default
visibility. Ditto when checking for local symbol to eliminate
pc-relative runtime relocs.
* Makefile.am: Add support for alpha-*-openbsd*, hppa-*-openbsd*,
powerpc-*-openbsd* and sparc64-*-openbsd*.
* Makefile.in: Regenerate.
* emulparams/hppaobsd.sh: New file.
