From 3b67f09464f771466473e64d44aa258f832d8b2d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marcin=20Ko=C5=9Bcielnicki?= Date: Fri, 3 Jun 2016 16:39:15 +0200 Subject: [PATCH] bfd/s390: Misc minor fixes. The only non-comment fix here is in the code writing out the 3 fixed .got.plt entries - it mistakenly put a 64-bit 0 at offsets 8 and 12 instead of 8 and 16. bfd/ChangeLog: * elf32-s390.c (elf_s390_finish_dynamic_symbol): Fix comment. * elf64-s390.c (elf_s390x_plt_entry): Fix comment. (elf_s390_relocate_section): Fix comment. (elf_s390_finish_dynamic_sections): Fix initialization of fixed .got.plt entries. --- bfd/ChangeLog | 8 ++++++++ bfd/elf32-s390.c | 2 +- bfd/elf64-s390.c | 8 ++++---- 3 files changed, 13 insertions(+), 5 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 7e4eb92e67..cb44986043 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,11 @@ +2016-06-07 Marcin Kościelnicki + + * elf32-s390.c (elf_s390_finish_dynamic_symbol): Fix comment. + * elf64-s390.c (elf_s390x_plt_entry): Fix comment. + (elf_s390_relocate_section): Fix comment. + (elf_s390_finish_dynamic_sections): Fix initialization of fixed + .got.plt entries. + 2016-06-07 Ulrich Weigand * elf64-s390.c (elf_s390_finish_dynamic_sections): Subtract plt diff --git a/bfd/elf32-s390.c b/bfd/elf32-s390.c index f3ee40c0f7..9480f7258a 100644 --- a/bfd/elf32-s390.c +++ b/bfd/elf32-s390.c @@ -3691,7 +3691,7 @@ elf_s390_finish_dynamic_symbol (bfd *output_bfd, /* Put in the GOT offset as displacement value.
