From 476366af6902bb771f71dd4746632bc466b65ddb Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 11 Feb 2013 18:20:51 +0000 Subject: [PATCH] bfd/ * elfxx-mips.c (mips_elf_count_got_entries): Delete. (mips_elf_check_recreate_got, mips_elf_recreate_got): Take a mips_elf_traverse_got_arg. Count GOT entries. (mips_elf_resolve_final_got_entries): Take the bfd_link_info as argument. Update after above changes. (mips_elf_merge_got, mips_elf_lay_out_got): Don't call mips_elf_count_got_entries. Update the calls to mips_elf_resolve_final_got_entries. --- bfd/ChangeLog | 11 +++++ bfd/elfxx-mips.c | 103 ++++++++++++++++++++--------------------------- 2 files changed, 55 insertions(+), 59 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index d3b2d8a1298..99e5e28c843 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,14 @@ +2013-02-11 Richard Sandiford + + * elfxx-mips.c (mips_elf_count_got_entries): Delete. + (mips_elf_check_recreate_got, mips_elf_recreate_got): Take a + mips_elf_traverse_got_arg.
