2014-11-25Fix corrupted .eh_frame section with LTO and --gc-sections.Cary Coutant1-6/+14
When --gc-sections is turned on during an LTO link, the .eh_frame sections from deferred files are processed before those from the replacement files. As a result, the section end-cap from crtendS.o is placed ahead of the .eh_frame data from the replacement files. This patch fixes the bug by skipping the layout of the deferred sections during GC pass 2. gold/ PR gold/17639 * object.cc (Sized_relobj_file): Initialize is_deferred_layout_. (Sized_relobj_file::do_layout): Handle deferred sections properly during GC pass 1. Don't add reloc sections to deferred list twice. * object.h (Sized_relobj_file::is_deferred_layout): New function.

2014-09-26Fix handling of relocations against TLS section symbols.Cary Coutant1-1/+3
Gold doesn't handle relocations against the section symbol for a TLS section correctly. Instead of using the offset of the section relative to the TLS segment, it uses the address of the actual section. This patch checks for section symbols for TLS sections, and treats them the same as TLS symbols. gold/ PR gold/16773 * object.cc (Sized_relobj_file): Compute value of section symbols for TLS sections the same as TLS symbols.
