Patch by matz@suse.de:
bfd/ChangeLog:
	* reloc.c: Add BFD_RELOC_X86_64_GOT64, BFD_RELOC_X86_64_GOTPCREL64,
	BFD_RELOC_X86_64_GOTPC64, BFD_RELOC_X86_64_GOTPLT64,
	BFD_RELOC_X86_64_PLTOFF64.
	* bfd-in2.h: Regenerated.
	* libbfd.h: Regenerated.
	* elf64-x86-64.c (x86_64_elf_howto_table): Correct comment.
	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.
