2019-01-08Remove support for old gnu v2 name mangling.Nick Clifton1-19/+7
PR 24044 * cxxfilt.c (hp_symbol_characters): Delete. (main): Remove depcreated demangling styles. * stabs.c (parse_stab_argtypes): Remove support for old gnu v2 demangling opnames. * testsuite/binutils-all/cxxfilt.exp: Use the --no-strip-underscore option for targets that do prefix their symbols with underscores. Update tests to elimiate those that use gnu v2 encoding.
2019-01-07Revert "Sync libiberty sources with master version in gcc repository. ↵Simon Marchi1-7/+19
Updated stabs demangling and cxxfilt tests to match." The previous commit breaks the GDB build, which is still using functions cplus_demangle_opname & co. Since removing these usages is not an obvious fix, let's revert this patch until we get rid of them.

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).
