Fred Fish 2e4964adfc * defs.h (STRCMP, STREQ, STREQN): New macros. 
* 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. (struct minimal_symbol, struct partial_symbol, struct
	  symbol): Use general_symbol_info struct.
	* utils.c (demangle_and_match):  Remove, no longer used.
	* valops.c (demangle.h):  Include.
	* xcoffexec.c (eq):  Remove macro, replace usages with STREQ.

	  symmisc.c, symtab.c, valops.c:  Replace references to minimal
	  symbol fields with appropriate macros.
	* breakpoint.c, buildsym.c, c-exp.y, c-typeprint.c, c-valprint.c,

	  references with SYMBOL_SOURCE_NAME or SYMBOL_LINKAGE_NAME as
	  appropriate.
	* buildsym.c (start_subfile, patch_subfile_names):  Default the
	  source language to what can be deduced from the filename.
	* buildsym.c (end_symtab):  Update the source language in the
	  allocated symtab to match what we have been using.
	* buildsym.h (struct subfile):  Add a language field.
