From 714e9a954a2e4123dcb26bb8da850e1344de4f5f Mon Sep 17 00:00:00 2001 From: Cupertino Miranda Date: Thu, 6 Sep 2018 00:50:35 +0100 Subject: [PATCH] [ARC] Fixed issue with DTSOFF relocs. Inserted offset in final section in the GOT entry of type DTSOFF soon to be relocated by the dynamic loader. bfd/ 2018-09-06 Cupertino Miranda * arc-got.h (relocate_fix_got_relocs_for_got_info): Changed. Take TLS section alignment in consideration for this relocation. * elf32-arc.c (FINAL_SECTSTART): Added this formula macro. (ARC_TLS_DTPOFF) Updated reloc to use new created macro instead. --- bfd/arc-got.h | 10 +++++++--- bfd/elf32-arc.c | 2 ++ include/elf/arc-reloc.def | 2 +- 3 files changed, 10 insertions(+), 4 deletions(-) diff --git a/bfd/arc-got.h b/bfd/arc-got.h index e32d9b3..07722fd 100644 --- a/bfd/arc-got.h +++ b/bfd/arc-got.h @@ -335,7 +335,11 @@ relocate_fix_got_relocs_for_got_info (struct got_entry ** list_p, bfd_vma sec_vma = tls_sec->output_section->vma; bfd_put_32 (output_bfd, - sym_value - sec_vma, + sym_value - sec_vma + + (elf_hash_table (info)->dynamic_sections_created + ? 0 + : (align_power (TCB_SIZE, + tls_sec->alignment_power))), htab->sgot->contents + entry->offset + (entry->existing_entries == TLS_GOT_MOD_AND_OFF ? 4 : 0)); @@ -346,7 +350,7 @@ relocate_fix_got_relocs_for_got_info (struct got_entry ** list_p, "GOT_TLS_IE"), (long) (sym_value - sec_vma), (long) (htab->sgot->output_section->vma - + htab->sgot->output_offset->vma + + htab->sgot->output_offset + entry->offset + (entry->existing_entries == TLS_GOT_MOD_AND_OFF ? 4 : 0)), @@ -376,7 +380,7 @@ relocate_fix_got_relocs_for_got_info (struct got_entry ** list_p, "GOT_TLS_IE"), (long) (sym_value - sec_vma), (long) (htab->sgot->output_section->vma - + htab->sgot->output_offset->vma + + htab->sgot->output_offset + entry->offset + (entry->existing_entries == TLS_GOT_MOD_AND_OFF ? 4 : 0)), diff --git a/bfd/elf32-arc.c b/bfd/elf32-arc.c index c52e2fb..7a1b304 100644 --- a/bfd/elf32-arc.c +++ b/bfd/elf32-arc.c @@ -1214,6 +1214,8 @@ arc_special_overflow_checks (const struct arc_relocation_data reloc_data, + (reloc_data.reloc_offset)))) #define SECTSTART (bfd_signed_vma) (reloc_data.sym_section->output_section->vma \ + reloc_data.sym_section->output_offset) +#define FINAL_SECTSTART \ + (bfd_signed_vma) (reloc_data.sym_section->output_section->vma) #define JLI (bfd_signed_vma) (reloc_data.sym_section->output_section->vma) #define _SDA_BASE_ (bfd_signed_vma) (reloc_data.sdata_begin_symbol_vma) #define TLS_REL (bfd_signed_vma) \ diff --git a/include/elf/arc-reloc.def b/include/elf/arc-reloc.def index e1c69c9..61edd6e 100644 --- a/include/elf/arc-reloc.def +++ b/include/elf/arc-reloc.def @@ -468,7 +468,7 @@ ARC_RELOC_HOWTO(ARC_TLS_DTPOFF, 67, \ 32, \ replace_word32, \ dont, \ - ( ME ( S - SECTSTART ) + A )) + ( ME ( S - FINAL_SECTSTART ) + A )) ARC_RELOC_HOWTO(ARC_TLS_DTPOFF_S9, 73, \ 2, \ -- 2.7.4
