Subject: mips.h (PREDICATE_CODES): Add ADDRESSOF for predicates that match register_operands.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=98c29f719c19ac2a166f19f14518f748952296d6;p=gcc.git

mips.h (PREDICATE_CODES): Add ADDRESSOF for predicates that match register_operands.

	* config/mips/mips.h (PREDICATE_CODES): Add ADDRESSOF for predicates
	that match register_operands.
	* config/mips/mips.c (reg_or_0_operand, true_reg_or_0_operand): Make
	register_operand the default case.
