[GOLD] reporting local symbol names
get_symbol_name currently returns "" for the usual STT_SECTION symbols
generated by gas. That's not very helpful, return the section name.
Demangle local symbols too, fixing an inconsistency in
issue_discarded_error where global symbols are demangled.
* object.cc (Sized_relobj_file::get_symbol_name): Return a
std::string. Return section name for STT_SECTION symbols with
zero st_name. Sanity check st_name, and don't run off the end
of an improperly terminated .strtab. Demangle sym names.
* object.h (Sized_relobj_file::get_symbol_name): Update decl.
* target-reloc.h (issue_discarded_error): Adjust.
* powerpc.cc (Target_powerpc::Relocate::relocate): Report reloc
type and symbol for relocation overflows.
