2014-06-06Strip .debug_gnu_pubnames and .debug_gnu_pubtypes when building .gdb_index.Cary Coutant1-6/+1
When not stripping those sections, there was a bug where gold was incorrectly adjusting section-relative offsets by the offset of the input section within the output section. That adjustment was both unnecessary and wrong, causing gold to miss a number of debug entries that should have been added to .gdb_index. (With stripping, the adjustment was always 0, so the bug in dwarf_reader.cc would have been hidden by the change to layout.cc.) gold/ * dwarf_reader.h (Dwarf_pubnames_table): Remove output_section_offset_. * dwarf_reader.cc (Dwarf_pubnames_table::read_section): Likewise. (Dwarf_pubnames_table::read_header): Likewise. * layout.cc (gdb_fast_lookup_sections): Add .debug_gnu_pubnames and .debug_gnu_pubtypes.

2014-01-28Add .gdb_index version 7 support.Cary Coutant1-3/+10
This patch adds support for .gdb_index version 7, which adds several flag bits to the symbol index. It also fixes a problem where it did not handle compressed debug sections correctly. Tested with a google/gcc-4_8 branch compiler, which supports the -ggnu-pubnames option to generate .debug_gnu_pubnames/pubtypes tables. (We will submit that patch to GCC when stage 1 reopens.) 2014-01-28 Cary Coutant <ccoutant@google.com> * gold/dwarf_reader.cc: include <utility> (for make_pair).
