Subject: i386.md (nonmemory_szext_operand): New mode attribute.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3e4ceed077aa7e94755fbf6bf213fd4305540bd9;p=gcc.git

i386.md (nonmemory_szext_operand): New mode attribute.

	* config/i386/i386.md (nonmemory_szext_operand): New mode attribute.
	(test<mode>_ccno_1): Macroize insn pattern from testsi_ccno_1
	and testdi_ccno_1 using SWI48 mode attribute.
	(*testdi_1): Use x86_64_szext_nonmemory_operand instead of
	x86_64_szext_general_operand.
	(*testqi_1_maybe_si): Use nonmemory_operand instead of general_operand.
	(*test<mode>_1): Use nonmemory_szext_operand mode attribute
	instead of genera_operand mode attribute.
