* defs.h (demangle_and_match): Remove prototype. * dwarfread.c (STREQ, STREQN): Remove macros, replaced with STREQ and STREQN defined in defs.h. * dwarfread.c (set_cu_language): For completely unknown languages, try to deduce the language from the filename. Retain behavior that for known languages we don't know how to handle, we use language_unknown. * dwarfread.c (enum_type, symthesize_typedef): Initialize language and demangled name fields in symbol. * dwarfread.c, mipsread.c, partial-stab.h: For all usages of ADD_PSYMBOL_TO_LIST, add language and objfile parameters. * dwarfread.c (new_symbol): Attempt to demangle C++ symbol names and cache the results in SYMBOL_DEMANGLED_NAME for the symbol. * elfread.c (STREQ): Remove macro, use STREQ defined in defs.h. Replace usages throughout. * elfread.c (demangle.h): Include. * elfread.c (record_minimal_symbol): Remove prototype and function. * gdbtypes.h, symtab.h (B_SET, B_CLR, B_TST, B_TYPE, B_BYTES, B_CLRALL): Moved from symtab.h to gdbtypes.h. * infcmd.c (jump_command): Remove code to demangle name and add it to a cleanup list. Now just use SYMBOL_DEMANGLED_NAME. * minsyms.c (demangle.h): Include. * minsyms.c (lookup_minimal_symbol): Indent comment to match code. * minsyms.c (install_minimal_symbols): Attempt to demangle symbol names as C++ names, and cache them in SYMBOL_DEMANGLED_NAME. * mipsread.c (psymtab_language): Add static variable. * stabsread.c (demangle.h): Include. * stabsread.c (define_symbol): Attempt to demangle C++ symbol names and cache them in the SYMBOL_DEMANGLED_NAME field. * stack.c (return_command): Remove explicit demangling of name and use of cleanups. Just use SYMBOL_DEMANGLED_NAME. * symfile.c (demangle.h): Include. * symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list): Fix to match macros in symfile.h and allow them to be compiled if INLINE_ADD_PSYMBOL is not true. * symfile.h (INLINE_ADD_PSYMBOL): Default to true if not set. * symfile.h (ADD_PSYMBOL_*): Add language and objfile parameters. Add code to demangle and cache C++ symbol names. Use macro form if INLINE_ADD_PSYMBOL is true, otherwise use C function form. * symmisc.c (add_psymbol_to_list, add_psymbol_addr_to_list): Remove, also defined in symfile.c, which we already fixed. * symtab.c (expensive_mangler): Remove prototype and function. * symtab.c (find_methods): Remove physnames parameter and fix prototype to match. * symtab.c (completion_list_add_symbol): Name changed to completion_list_add_name. * symtab.c (COMPLETION_LIST_ADD_SYMBOL): New macro, adds both the normal symbol name and the cached C++ demangled name. * symtab.c (lookup_demangled_partial_symbol, lookup_demangled_block_symbol): Remove prototypes and functions. * symtab.c (lookup_symbol): Remove use of expensive_mangler, use lookup_block_symbol instead of lookup_demangled_block_symbol. Remove code to try demangling names and matching them. * symtab.c (lookup_partial_symbol, lookup_block_symbol): Fix to try matching the cached demangled name if no match is found using the regular symbol name. * symtab.c (find_methods): Remove unused physnames array. * symtab.c (name_match, NAME_MATCH): Remove function and macro, replaced with SYMBOL_MATCHES_REGEXP from symtab.h. * symtab.c (completion_list_add_symbol): Rewrite to use cached C++ demangled symbol names. * symtab.h: Much reformatting of structures and such to add whitespace to make them more readable, and make them more consistent with other gdb structure definitions. * symtab.h (general_symbol_info): New struct containing fields common to all symbols. * symtab.h (SYMBOL_LANGUAGE, SYMBOL_DEMANGLED_NAME, SYMBOL_SOURCE_NAME, SYMBOL_LINKAGE_NAME, SYMBOL_MATCHES_NAME, SYMBOL_MATCHES_REGEXP, MSYMBOL_INFO, MSYMBOL_TYPE): New macros. * symtab.
