gold --emit-relocs
A symbol value in an ELF final linked binary is absolute, in contrast to a relocatable object file where the value is section relative. For --emit-relocs it is therefore incorrect to use the value of a section symbol as the addend when adjusting relocs against input section symbols to output section symbols. PR gold/18846 * target-reloc.h (relocate_relocs <RELOC_ADJUST_FOR_SECTION_RELA>): Subtract os->address() from addend. * powerpc.cc (relocate_relocs): Likewise.
