From 34e967a5f3ac5fd0353731a259e358d462823290 Mon Sep 17 00:00:00 2001 From: Miranda Cupertino Date: Tue, 19 Jan 2016 15:25:58 +0000 Subject: Add PIC and TLS support to the ARC target. bfd/ChangeLog: * arc-plt.def: New file. * arc-plt.h: Likewise. * elf32-arc.c (elf_arc_abs_plt0_entry, elf_arc_abs_pltn_entry, elf_arcV2_abs_plt0_entry, elf_arcV2_abs_pltn_entry, elf_arc_pic_plt0_entry, elf_arc_pic_pltn_entry, elf_arcV2_pic_plt0_entry, elf_arcV2_pic_pltn_entry): Remove. (name_for_global_symbol): Added. (ADD_RELA): Helper to create dynamic relocs. (new_got_entry_to_list): Create a new got entry in linked list. (symbol_has_entry_of_type): Search for specific type of entry in list. (is_reloc_for_GOT): return FALSE for any TLS related relocs. (is_reloc_for_TLS, arc_elf_set_private_flags) (arc_elf_print_private_bfd_data, arc_elf_copy_private_bfd_data) (arc_elf_merge_private_bfd_data): New functions. (debug_arc_reloc): Cleaned debug info printing. (PDATA reloc): Changed not to perform address alignment. (reverse_me): Added. Fix for ARC_32 relocs. (arc_do_relocation): Return bfd_reloc_of when no relocation should occur. (arc_get_local_got_ents): Renamed from arc_get_local_got_offsets. Changed function to access an array of list of GOT entries instead of just an array of offsets. (elf_arc_relocate_section): Added support for PIC and TLS related relocations. (elf_arc_check_relocs): Likewise. (elf_arc_adjust_dynamic_symbol, elf_arc_finish_dynamic_symbol, (elf_arc_finish_dynamic_sections): Likewise (arc_create_dynamic_sections): Modified conditions to create dynamic sections. (ADD_SYMBOL_REF_SEC_AND_RELOC): New macro. (plt_do_relocs_for_symbol, relocate_plt_for_symbol) (relocate_plt_for_entry): Changed to support new way to define PLT related code. (add_symbol_to_plt): Likewise. (arc_elf_link_hash_table_create): New function. include/ChangeLog: * elf/arc-reloc.def (ARC_32, ARC_GOTPC, ARC_TLS_GD_GOT) (ARC_TLS_IE_GOT, ARC_TLS_DTPOFF, ARC_TLS_DTPOFF_S9, ARC_TLS_LE_S9) (ARC_TLS_LE_32): Fixed formula. (ARC_TLS_GD_LD): Use new special function. * opcode/arc-func.h: Changed all the replacement functions to clear the patching bits before doing an or it with the value argument. --- binutils/ChangeLog | 6 ++++++ binutils/readelf.c | 26 +++++++++++++++++++++++--- 2 files changed, 29 insertions(+), 3 deletions(-) (limited to 'binutils') diff --git a/binutils/ChangeLog b/binutils/ChangeLog index c5b52f4..1db49d2 100644 --- a/binutils/ChangeLog +++ b/binutils/ChangeLog @@ -1,3 +1,9 @@ +2016-01-18 Miranda Cupertino + Zissulescu Claudiu + + * readelf.c (get_machine_flags): Add support for newer ARC ELF + header flags. + 2016-01-18 Alan Modra * configure: Regenerate. diff --git a/binutils/readelf.c b/binutils/readelf.c index f74ef7b..7391334 100644 --- a/binutils/readelf.c +++ b/binutils/readelf.c @@ -2776,17 +2776,37 @@ get_machine_flags (unsigned e_flags, unsigned e_machine) case EF_ARC_CPU_ARCV2HS: strcat (buf, ", ARC HS"); break; + case EF_ARC_CPU_GENERIC: + strcat (buf, ", ARC generic"); + break; + case E_ARC_MACH_ARC600: + strcat (buf, ", ARC600"); + break; + case E_ARC_MACH_ARC601: + strcat (buf, ", ARC601"); + break; + case E_ARC_MACH_ARC700: + strcat (buf, ", ARC700"); + break; default: - strcat (buf, ", unrecognized flag for ARCv2"); + strcat (buf, ", unrecognized cpu flag for ARCv2"); break; } switch (e_flags & EF_ARC_OSABI_MSK) { - /* Only upstream 3.9+ kernels will support ARCv2 - ISA. */ + case E_ARC_OSABI_ORIG: + strcat (buf, ", (ABI:legacy)"); + break; + case E_ARC_OSABI_V2: + strcat (buf, ", (ABI:v2)"); + break; + /* Only upstream 3.9+ kernels will support ARCv2 ISA. */ case E_ARC_OSABI_V3: strcat (buf, ", v3 no-legacy-syscalls ABI"); break; + default: + strcat (buf, ", unrecognised ARC OSABI flag"); + break; } break; -- cgit v1.1
