Ian Lance Taylor 7d4210142a Rework last checkin to the following:
* 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.

Ian Lance Taylor 5076851fbc * i386-dis.c (FWAIT_OPCODE): Define.
(fetch_data): Don't print an error message if we have already
	found an fwait prefix.
	(ckprefix): Use FWAIT_OPCODE rather than 0x9b.

	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.
