binutils-gdb/libiberty/config.in
Nick Clifton af03af8f55 Synchronize libiberty with gcc and add --no-recruse-limit option to tools that support name demangling. 
This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code.  It adds a limit to the amount of
recursion that is allowed, before an error is triggered.  It also adds a
new demangling option to disable this limit.  (The limit is enabled by
default).

	PR 87681
	PR 87675
	PR 87636
	PR 87335
libiberty * cp-demangle.h (struct d_info): Add recursion_limit field.
	* cp-demangle.c (d_function_type): If the recursion limit is
	enabled and reached, return with a failure result.
        (d_demangle_callback): If the recursion limit is enabled, check
	for a mangled string that is so long that there is not enough
	stack space for the local arrays.
        * cplus-dem.c (struct work): Add recursion_level field.
	(demangle_nested_args): If the recursion limit is enabled and
	reached, return with a failure result.

include	* demangle.h (DMGL_RECURSE_LIMIT): Define.
        (DEMANGLE_RECURSION_LIMIT): Prototype.

binutuils * addr2line.c (demangle_flags): New static variable.
        (long_options): Add --recurse-limit and --no-recurse-limit.
        (translate_address): Pass demangle_flags to bfd_demangle.
        (main): Handle --recurse-limit and --no-recurse-limit options.
        * cxxfilt.c (flags): Add DMGL_RECURSE_LIMIT.
        (long_options): Add --recurse-limit and --no-recurse-limit.
        (main): Handle new options.
        * dlltool.c (gen_def_file): Include DMGL_RECURSE_LIMIT in flags
        passed to cplus_demangle.
        * nm.c (demangle_flags): New static variable.
        (long_options): Add --recurse-limit and --no-recurse-limit.
        (main): Handle new options.
        * objdump.c (demangle_flags): New static variable.
        (usage): Add --recurse-limit and --no-recurse-limit.
        (long_options): Likewise.
        (objdump_print_symname): Pass demangle_flags to bfd_demangle.
        (disassemble_section): Likewise.
        (dump_dymbols): Likewise.
        (main): Handle new options.
        * prdbg.c (demangle_flags): New static variable.
        (tg_variable): Pass demangle_flags to demangler.
        (tg_start_function): Likewise.
        * stabs.c (demangle_flags): New static variable.
        (stab_demangle_template): Pass demangle_flags to demangler.
        (stab_demangle_v3_argtypes): Likewise.
        (stab_demangle_v3_arg): Likewise.
	* doc/binutuls.texi: Document new command line options.
	* NEWS: Mention the new feature.
        * testsuite/config/default.exp (CXXFILT): Define if not already
        defined.
        (CXXFILTFLAGS): Likewise.
        * testsuite/binutils-all/cxxfilt.exp: New file.  Runs a few
        simple tests of the cxxfilt program.
