Fred Fish 7532cf103a * tm-sun4sol2.h (CPLUS_MARKER): Remove, now set in tm-sysv4.h.
* 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 ****

#include "solib.h" /* Support for shared libraries. */
/* 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. */

/* In SVR4 ELF files, the ABI defines (pg. 4-25) that "External C symbols

tables." So... */

/* It is unknown which, if any, SVR4 assemblers do not accept dollar signs
in identifiers. The default in G++ is to use dots instead, for all SVR4
systems, so we make that our default also. FIXME: There should be some
way to get G++ to tell us what CPLUS_MARKER it is using, perhaps by
stashing it in the debugging information as part of the name of an
invented symbol ("gcc_cplus_marker$" for example). */
