(need_modrm): Give it file scope.
(MODRM_CHECK): Define.
(dofloat): Use MODRM_CHECK.
(OP_E): Likewise.
(OP_EM): Likewise.
(OP_EX): Likewise.
and fix testsuite yet again now that we are getting correct disassembly.
(dis386_twobyt): Add SSE2 instructions.
(twobyte_uses_SSE_prefix: Rename from ... ; add new SSE instructions.
(twobyte_uses_f3_prefix): ... this one.
(grps): Add SSE instructions.
(prefix_user_table): Add two new slots; add SSE2 instructions.
(print_insn_i386): Rename uses_f3_prefix to uses_SSE_prefix;
Handle the REPNZ and Data16 prefixes as well; do proper lookup
to prefix_user_table.
(OP_E): Accept mfence and lfence as well.
(OP_MMX): Data16 prefix turns MMX to SSE; support REX extensions.
(OP_XMM): Support REX extensions.
(OP_EM): Likewise.
(OP_EX): Likewise.
(rex): New static variable.
(REX_MODE64, REX_EXTX, REX_EXTY, REX_EXTZ): New constants.

(OP_REG, OP_OFF): Declare.
(get64, get32, get32s): New functions.
(r??_reg): New constants.
(dis386_att): Change templates of instruction implicitly promoted
to 64bit; change e?? to RMe?? for unwind RM byte instructions.

(names64, names8rex): New global variable.
(names32, names16): Add extended registers.
(prefix_user_t): Recognize rex prefixes.
(prefix_name): Print REX prefixes nicely.
(op_riprel): New global variable.
(start_pc): Set type to bfd_vma.
(print_insn_i386): Detect the 64bit mode and use proper table;
move ckprefix after initializing the buffer; output unused rex prefixes;
output information about target of RIP relative addresses.
(putop): Support 'O' and 'I'. Update handling of "P', 'Q', 'R' and 'S';
(print_operand_value): New function.
(OP_E, OP_G, OP_REG, OP_I, OP_J, OP_DIR, OP_OFF, OP_D): Add support for
REX prefix and new modes.
(get64, get32s): New.
(get32): Return bfd_signed_vma type.
(set_op): Initialize the op_riprel.
* disassemble.c (disassembler): Recognize the x86-64 disassembly.
(generic_strcat_address): Add cast to avoid warning.
* i386-dis.c: Initialize all structure fields to avoid warnings.
Add ATTRIBUTE_UNUSED as appropriate.
* i386-dis.c (FWAIT_OPCODE): Define.
(used_prefixes): New static variable.
(fetch_data): Don't print an error message if we have already
fetched some bytes successfully.
(ckprefix): Clear used_prefixes. Use FWAIT_OPCODE, not 0x9b.
(prefix_name): New static function.
(print_insn_i386): If setjmp fails, indicating a data error, but
we have managed to fetch some bytes, print the first one as a
prefix or a .byte pseudo-op. If fwait is followed by a non
floating point instruction, print the first prefix. Set
used_prefixes when prefixes are used. If any prefixes were not
used after disassembling the instruction, print the first prefix
instead of printing the instruction.
(putop): Set used_prefixes when prefixes are used.
(append_seg, OP_E, OP_G, OP_REG, OP_I, OP_sI, OP_J): Likewise.
(OP_DIR, OP_SIMD_Suffix): Likewise.
(fetch_data): Don't print an error message if we have already
found an fwait prefix.
(ckprefix): Use FWAIT_OPCODE rather than 0x9b.
(print_insn_i386): If setjmp fails, indicating a data error, but
we have found an fwait prefix, then print it as an fwait
instruction. In any case, return the number of bytes consumed, if
any, rather than always returning -1.
Add missing files from last change in gas/testsuite.
i386-dis.c: Catch a number of cases where an invalid modrm would result in
bogus disassembly. const lots of places.
