Add howtos for above relocs. (x86_64_reloc_map): Add mappings for new relocs. (elf64_x86_64_check_relocs): R_X86_64_GOT64, R_X86_64_GOTPCREL64, R_X86_64_GOTPLT64 need a got entry. R_X86_64_GOTPLT64 also a PLT entry. R_X86_64_GOTPC64 needs a .got section. R_X86_64_PLTOFF64 needs a PLT entry. (elf64_x86_64_gc_sweep_hook): Reflect changes from elf64_x86_64_check_relocs for the new relocs. (elf64_x86_64_relocate_section): Handle new relocs. gas/ChangeLog: * config/tc-i386.c (type_names): Correct placement of 'static'. (reloc): Map some more relocs to their 64 bit counterpart when size is 8. (output_insn): Work around breakage if DEBUG386 is defined. (output_disp): A BFD_RELOC_64 with GOT_symbol as operand also needs to be mapped to BFD_RELOC_X86_64_GOTPC64 or BFD_RELOC_X86_64_GOTPC32. Also x86-64 handles pcrel addressing different from i386. (output_imm): Ditto. (lex_got): Recognize @PLTOFF and @GOTPLT. Make @GOT accept also Imm64. (md_convert_frag): Jumps can now be larger than 2GB away, error out in that case. (tc_gen_reloc): New relocs are passed through. BFD_RELOC_64 and BFD_RELOC_64_PCREL are mapped to BFD_RELOC_X86_64_GOTPC64. gas/testsuite/ChangeLog: * gas/i386/reloc64.s: Accept 64-bit forms. * gas/i386/reloc64.d: Adjust. * gas/i386/reloc64.l: Adjust. include/ChangeLog: * elf/x86-64.h: Add the new relocations with their official numbers.
