texthigh and textlow to reader-specific structs caused
objfile_relocate to miss them. This is fixable, but the work that
the change was supposed to prepare GDB for never got done anyway.
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.
* symfile.c (get_section_index): New function.
* mdebugread.c (SC_IS_SBSS): New macro.
(SC_IS_BSS): Return true for the scBss storage class only, as
the scSBss storage class refers to the .sbss section.
(parse_partial_symbols): Discard the symbols which associated
section does not exist.
Make sure to use the .sbss section index for symbols which
storage class is scBss, rather than using the .bss section index.

* mdebugread.c (parse_partial_symbols): Only copy stabstring1 to
stabstring on initial malloc. Reallocing will copy it for us,
if necessary.
of `struct partial_symtab' to only a few locations. This change
is not supposed to affect the way the values are computed, only
where they live.
* dbxread.c (struct symloc): Add `textlow' and `texthigh' fields
to the reader-specific structure.
* mdebugread.c (struct symloc): Same.
* dbxread.c (TEXTLOW, TEXTHIGH): New accessor macros.
* mdebugread.c (TEXTLOW, TEXTHIGH): Same.
* dbxread.c (dbx_symfile_read): After we've built all our partial
symbol tables, set each partial symtab's `textlow' and `texthigh'
fields from our reader-specific structure.
* mdebugread.c (mdebug_build_psymtabs): Same.
* dbxread.c (start_psymtab): Initialize the reader-specific
structure's `textlow' and `texthigh' from the new psymtab's.
* mdebugread.c (parse_partial_symbols, new_psymtab): Same.
* dbxread.c (read_dbx_symtab, end_psymtab, read_ofile_symtab): Use
the reader-specific `textlow' and `texthigh', not the generic
psymtab fields.
* mdebugread.c (parse_lines, parse_partial_symbols,
psymtab_to_symtab_1): Same.
* partial-stab.h: Same.

* dbxread.c (free_header_files): Make global.
(init_header_files): Likewise.
* stabsread.h (free_header_files): Add prototype.
(init_header_files): Likewise.
* mdebugread.c (mdebug_build_psymtabs): Initialize
properly before using the stabs debug reader.
address range of a compilation unit without children.
* mdebugread.c (parse_partial_symbols): Fix handling of stabs
continuations, use xmalloc and xrealloc.
section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
Only worked if the first element in the list was
being deleted.
o When MAINLINE (reading main objectfile and need to
clear out old data), change elfread.c so that the
psymbol table is emptied once (in elf_symfile_read)
instead of multiple times in each *_read_psymtab
function.
o For elf_symfile_read, load dwarf2 symbols last
(so that they are searched for first).
o In mdebug_psymtab_read, delete check to see if
symbols for current source file already loaded.
Test doesn't work for .h files. Above change
works better
entries.
* dbxread.c: More comment cleanups.
* stabsread.c: Fix various violations of the GNU coding and
formatting standards. Update/add comments to make code clearer.
(resolve_reference): Delete unused function.
(ref_search_val): Remove function. It didn't belong in stabsread.c
(resolve_live_range): No longer returns a value. Do not add it
to the live range list until the entire range stab has been parsed.
(get_substring): Remove duplicate declaration.
(resolve_symbol_reference): Now static. Remove unnecessary code
to deal with cleanups.
(ref_add): Use xrealloc instea of realloc.

Bring first round of cleanups over from r5900 branch.
(end_psymtab): Use MSYMBOL_SIZE to extract size from minimal symbol.
* elfread.c (elf_symtab_read): If ELF symbol is "special",
such as a MIPS16 function, mark minimal symbol as special too.
* mips-tdep.c (pc_is_mips16): New function to check whether
a function is MIPS16 by looking at the minimal symbol. Use
pc_is_mips16 throughout instead of IS_MIPS16_ADDR macro.
* config/mips/tm-mips.h (SYMBOL_IS_SPECIAL, MAKE_MSYMBOL_SPECIAL,
MSYMBOL_IS_SPECIAL, MSYMBOL_SIZE): New functions for setting/testing
"special" MIPS16 bit in ELF and minimal symbols.
* mdebugread.c (parse_partial_symbols): Don't construct a partial
symbol table for a file that already has one.
