Subject: * elfxx-mips.c (mips_elf_get_global_gotsym_index): New.
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=0176c794f8a432e7f115af1dfb8f9ad6f24a0a5e;p=deliverable%2Fbinutils-gdb.git

* elfxx-mips.c (mips_elf_get_global_gotsym_index): New.
(mips_elf_calculate_relocation): Decay GOT_PAGE/GOT_OFST to
GOT_DISP/addend only if the symbol got a global GOT entry.
