include/opcode/

	* i386.h (i386_optab): Remove fildd, fistpd and fisttpd.

opcodes/
	* i386-dis.c (x_mode): Comment.
	(two_source_ops): File scope.
	(float_mem): Correct fisttpll and fistpll.
	(float_mem_mode): New table.
	(dofloat): Use it.
	(OP_E): Correct intel mode PTR output.
	(ptr_reg): Use open_char and close_char.
	(PNI_Fixup): Handle possible suffix on sidt.  Use op1out etc. for
	operands.  Set two_source_ops.

gas/testsuite/
	* gas/i386/prescott.s: Remove fisttpd and fisttpq.
	* gas/i386/prescott.d: Update.
