Subject: rs6000: Clean up the cstore code a bit
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=586cdac8e5af3fff142829e579558f8728e56f81;p=gcc.git

rs6000: Clean up the cstore code a bit

"register_operand" was a bit confusing.  Also some other minor cleanups.


	* (cstore<mode>4_unsigned): Use gpc_reg_operand instead of
	register_operand.  Remove empty constraints.  Use std::swap.
	(cstore_si_as_di, cstore<mode>4_signed_imm,
	cstore<mode>4_unsigned_imm, cstore<mode>4 for GPR): Use
	gpc_reg_operand instead of register_operand.
	(cstore<mode>4 for FP): Use gpc_reg_operand instead of
	register_operand.  Remove empty constraints.
