* tm-sysv4.h (CPLUS_MARKER): By default, g++ uses '.' as the CPLUS_MARKER for all SVR4 systems, so follow suit. * defs.h (strdup_demangled): Remove prototype. * dwarfread.c (enum_type, synthesize_typedef): Use new macro SYMBOL_INIT_LANGUAGE_SPECIFIC. * dwarfread.c (new_symbol): Use SYMBOL_INIT_DEMANGLED_NAME. * minsyms.c (install_minimal_symbols, prim_record_minimal_symbol, prim_record_minimal_symbol_and_info): Use new macro SYMBOL_INIT_LANGUAGE_SPECIFIC. * minsyms.c (install_minimal_symbols): Use new macro SYMBOL_INIT_DEMANGLED_NAME. * stabsread.c (define_symbol): Use new macro SYMBOL_INIT_DEMANGLED_NAME. * symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list): Use new macro SYMBOL_INIT_DEMANGLED_NAME. * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Use new macro SYMBOL_INIT_DEMANGLED_NAME. * symmisc.c (dump_msymbols, dump_symtab, print_partial_symbol): SYMBOL_DEMANGLED_NAME now tests language itself. * symtab.c (COMPLETION_LIST_ADD_SYMBOL): SYMBOL_DEMANGLED_NAME now tests language itself. * symtab.h (SYMBOL_CPLUS_DEMANGLED_NAME): New macro that does what SYMBOL_DEMANGLED_NAME used to do, directly access the C++ mangled name member in the language dependent portion of a symbol. * symtab.h (SYMBOL_DEMANGLED_NAME): New macro that returns the mangled name member appropriate for a symbol's language. * symtab.h (SYMBOL_SOURCE_NAME, SYMBOL_LINKAGE_NAME, SYMBOL_MATCHES_NAME, SYMBOL_MATCHES_REGEXP): SYMBOL_DEMANGLED_NAME now tests language itself. * symtab.h (SYMBOL_INIT_LANGUAGE_SPECIFIC): New macro that initializes language dependent portion of symbol. * symtab.h (SYMBOL_INIT_DEMANGLED_NAME): New macro that demangles and caches the demangled form of symbol names. * utils.c (fputs_demangled, fprint_symbol): Use current language to select an appropriate demangling algorithm. * utils.c (strdup_demangled): Remove, no longer used. **** start-sanitize-chill **** * symtab.h (SYMBOL_CHILL_DEMANGLED_NAME): New macro that directly access the Chill mangled name member in the language dependent portion of a symbol. * ch-lang.c (chill_demangle): New function, simple demangler. * defs.h (chill_demangle): Add prototype. * symtab.h (language_dependent_info): Add struct for Chill. **** end-sanitize-chill ****

/* For SVR4 shared libraries, each call to a library routine goes through
|
|
a small piece of trampoline code in the ".init" section. Although each
|
|
of these fragments is labeled with the name of the routine being called,
|
|
the gdb symbol reading code deliberately ignores them so it won't confuse
|
|
them with the real functions. It does however know about the label that
|
|
precedes all of the fragments, which is "_init". Thus when we lookup a
|
|
function that corresponds to a PC value which is in one of the trampoline
|
|
fragments, we'll appear to be in the function "_init". The following
|
|
macro will evaluate to nonzero when NAME is valid and matches "_init".
|
|
The horribly ugly wait_for_inferior() routine uses this macro to detect
|
|
when we have stepped into one of these fragments. */

way to get G++ to tell us what CPLUS_MARKER it is using, perhaps by
