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.

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.
