This adds support for the new x86-64 relocation types added in ABI draft 0.95 (or in a slightly earlier version). In addition, it fixes the overflow complaint types for two x86-64 and one i386 relocation types. Built and tested on i686-pc-linux-gnu and x86_64-unknown-linux-gnu. Jan bfd/ 2005-06-08 Jan Beulich <jbeulich@novell.com> * bfd-in2.h (elf_x86_64_reloc_type): Add BFD_RELOC_X86_64_GOTOFF64 and BFD_RELOC_X86_64_GOTPC32. * libbfd.h (bfd_reloc_code_real_names): Likewise. * elf64-x86-64.c (x86_64_elf_howto_table): Adjust overflow complaint handler for R_X86_64_PC16 and R_X86_64_8. Add entries for R_X86_64_PC64, R_X86_64_GOTOFF64, and R_X86_64_GOTPC32. (x86_64_reloc_map): Add entries for R_X86_64_PC64, R_X86_64_GOTOFF64, and R_X86_64_GOTPC32. (elf64_x86_64_info_to_howto): Adjust bounding relocation type. (elf64_x86_64_check_relocs): Also handle R_X86_64_PC64, R_X86_64_GOTOFF64, and R_X86_64_GOTPC32. (elf64_x86_64_relocate_section): Likewise. (elf64_x86_64_gc_sweep_hook): Also handle R_X86_64_PC64. * elf32-i386.c (elf_howto_table): Adjust overflow complaint handler for R_386_PC16. gas/ 2005-06-08 Jan Beulich <jbeulich@novell.com> * config/tc-i386.c (reloc): Also handle BFD_RELOC_64_PCREL. (tc_i386_fix_adjustable): Include BFD_RELOC_X86_64_GOTOFF64. (output_disp): Use BFD_RELOC_X86_64_GOTPC32 instead of aborting. (output_imm): Likewise. (tc_gen_reloc): Likewise. Also handle BFD_RELOC_X86_64_GOTOFF64 and BFD_RELOC_X86_64_GOTPC32. Also convert 8-byte pc-relative relocations. (lex_got): Use BFD_RELOC_X86_64_GOTOFF64 for 64-bit @gotoff. (i386_validate_fix): Likewise. (x86_cons): Also handle quad values in 64-bit mode. (i386_displacement): Also handle BFD_RELOC_X86_64_GOTOFF64. (md_apply_fix): Also handle convert BFD_RELOC_64 to pc-relative variant. Also check for BFD_RELOC_64_PCREL. gas/testsuite/ 2005-06-08 Jan Beulich <jbeulich@novell.com> * gas/i386/x86-64-pcrel.s: Add insn requiring 64-bit pc-relative relocation. Add insns for all widths of non-pc-relative relocations. * gas/i386/x86-64-pcrel.d: Adjust. include/elf/ 2005-06-08 Jan Beulich <jbeulich@novell.com> * x86-64.h (elf_x86_64_reloc_type): Adjust comment for R_X86_64_GOTPCREL. Add R_X86_64_PC64, R_X86_64_GOTOFF64, and R_X86_64_GOTPC32. --- /home/jbeulich/src/binutils/mainline/2005-06-08/bfd/bfd-in2.h 2005-06-08 14:50:36.000000000 +0200 +++ 2005-06-08/bfd/bfd-in2.h 2005-06-08 15:41:20.906779680 +0200 @@ -2617,6 +2617,8 @@ in the instruction. */ BFD_RELOC_X86_64_DTPOFF32, BFD_RELOC_X86_64_GOTTPOFF, BFD_RELOC_X86_64_TPOFF32, + BFD_RELOC_X86_64_GOTOFF64, + BFD_RELOC_X86_64_GOTPC32, /* ns32k relocations */ BFD_RELOC_NS32K_IMM_8, --- /home/jbeulich/src/binutils/mainline/2005-06-08/bfd/elf32-i386.c 2005-06-08 14:50:38.000000000 +0200 +++ 2005-06-08/bfd/elf32-i386.c 2005-06-08 15:41:20.913778616 +0200 @@ -95,7 +95,7 @@ static reloc_howto_type elf_howto_table[ HOWTO(R_386_16, 0, 1, 16, FALSE, 0, complain_overflow_bitfield, bfd_elf_generic_reloc, "R_386_16", TRUE, 0xffff, 0xffff, FALSE), - HOWTO(R_386_PC16, 0, 1, 16, TRUE, 0, complain_overflow_bitfield, + HOWTO(R_386_PC16, 0, 1, 16, TRUE, 0, complain_overflow_signed, bfd_elf_generic_reloc, "R_386_PC16", TRUE, 0xffff, 0xffff, TRUE), HOWTO(R_386_8, 0, 0, 8, FALSE, 0, complain_overflow_bitfield, --- /home/jbeulich/src/binutils/mainline/2005-06-08/bfd/elf64-x86-64.c 2005-05-18 08:09:48.000000000 +0200 +++ 2005-06-08/bfd/elf64-x86-64.c 2005-06-08 15:41:20.944773904 +0200 @@ -73,9 +73,9 @@ static reloc_howto_type x86_64_elf_howto FALSE), HOWTO(R_X86_64_16, 0, 1, 16, FALSE, 0, complain_overflow_bitfield, bfd_elf_generic_reloc, "R_X86_64_16", FALSE, 0xffff, 0xffff, FALSE), - HOWTO(R_X86_64_PC16,0, 1, 16, TRUE, 0, complain_overflow_bitfield, + HOWTO(R_X86_64_PC16,0, 1, 16, TRUE, 0, complain_overflow_signed, bfd_elf_generic_reloc, "R_X86_64_PC16", FALSE, 0xffff, 0xffff, TRUE), - HOWTO(R_X86_64_8, 0, 0, 8, FALSE, 0, complain_overflow_signed, + HOWTO(R_X86_64_8, 0, 0, 8, FALSE, 0, complain_overflow_bitfield, bfd_elf_generic_reloc, "R_X86_64_8", FALSE, 0xff, 0xff, FALSE), HOWTO(R_X86_64_PC8, 0, 0, 8, TRUE, 0, complain_overflow_signed, bfd_elf_generic_reloc, "R_X86_64_PC8", FALSE, 0xff, 0xff, TRUE), @@ -103,6 +103,15 @@ static reloc_howto_type x86_64_elf_howto HOWTO(R_X86_64_TPOFF32, 0, 2, 32, FALSE, 0, complain_overflow_signed, bfd_elf_generic_reloc, "R_X86_64_TPOFF32", FALSE, 0xffffffff, 0xffffffff, FALSE), + HOWTO(R_X86_64_PC64, 0, 4, 64, TRUE, 0, complain_overflow_bitfield, + bfd_elf_generic_reloc, "R_X86_64_PC64", FALSE, MINUS_ONE, MINUS_ONE, + TRUE), + HOWTO(R_X86_64_GOTOFF64, 0, 4, 64, FALSE, 0, complain_overflow_bitfield, + bfd_elf_generic_reloc, "R_X86_64_GOTOFF64", + FALSE, MINUS_ONE, MINUS_ONE, FALSE), + HOWTO(R_X86_64_GOTPC32, 0, 2, 32, TRUE, 0, complain_overflow_signed, + bfd_elf_generic_reloc, "R_X86_64_GOTPC32", + FALSE, 0xffffffff, 0xffffffff, TRUE), /* GNU extension to record C++ vtable hierarchy. */ HOWTO (R_X86_64_GNU_VTINHERIT, 0, 4, 0, FALSE, 0, complain_overflow_dont, @@ -147,6 +156,9 @@ static const struct elf_reloc_map x86_64 { BFD_RELOC_X86_64_DTPOFF32, R_X86_64_DTPOFF32, }, { BFD_RELOC_X86_64_GOTTPOFF, R_X86_64_GOTTPOFF, }, { BFD_RELOC_X86_64_TPOFF32, R_X86_64_TPOFF32, }, + { BFD_RELOC_64_PCREL, R_X86_64_PC64, }, + { BFD_RELOC_X86_64_GOTOFF64, R_X86_64_GOTOFF64, }, + { BFD_RELOC_X86_64_GOTPC32, R_X86_64_GOTPC32, }, { BFD_RELOC_VTABLE_INHERIT, R_X86_64_GNU_VTINHERIT, }, { BFD_RELOC_VTABLE_ENTRY, R_X86_64_GNU_VTENTRY, }, }; @@ -179,13 +191,13 @@ elf64_x86_64_info_to_howto (bfd *abfd AT r_type = ELF64_R_TYPE (dst->r_info); if (r_type < (unsigned int) R_X86_64_GNU_VTINHERIT) { - BFD_ASSERT (r_type <= (unsigned int) R_X86_64_TPOFF32); + BFD_ASSERT (r_type <= (unsigned int) R_X86_64_GOTPC32); i = r_type; } else { BFD_ASSERT (r_type < (unsigned int) R_X86_64_max); - i = r_type - ((unsigned int) R_X86_64_GNU_VTINHERIT - R_X86_64_TPOFF32 - 1); + i = r_type - ((unsigned int) R_X86_64_GNU_VTINHERIT - R_X86_64_GOTPC32 - 1); } cache_ptr->howto = &x86_64_elf_howto_table[i]; BFD_ASSERT (r_type == cache_ptr->howto->type); @@ -749,7 +761,8 @@ elf64_x86_64_check_relocs (bfd *abfd, st } /* Fall through */ - //case R_X86_64_GOTPCREL: + case R_X86_64_GOTOFF64: + case R_X86_64_GOTPC32: create_got: if (htab->sgot == NULL) { @@ -802,6 +815,7 @@ elf64_x86_64_check_relocs (bfd *abfd, st case R_X86_64_PC8: case R_X86_64_PC16: case R_X86_64_PC32: + case R_X86_64_PC64: case R_X86_64_64: if (h != NULL && !info->shared) { @@ -816,7 +830,7 @@ elf64_x86_64_check_relocs (bfd *abfd, st /* We may need a .plt entry if the function this reloc refers to is in a shared lib. */ h->plt.refcount += 1; - if (r_type != R_X86_64_PC32) + if (r_type != R_X86_64_PC32 && r_type != R_X86_64_PC64) h->pointer_equality_needed = 1; } @@ -845,7 +859,8 @@ elf64_x86_64_check_relocs (bfd *abfd, st && (sec->flags & SEC_ALLOC) != 0 && (((r_type != R_X86_64_PC8) && (r_type != R_X86_64_PC16) - && (r_type != R_X86_64_PC32)) + && (r_type != R_X86_64_PC32) + && (r_type != R_X86_64_PC64)) || (h != NULL && (!
