Subject: MSP430: Support a memory operand for op1 of andneghi3
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8c3846e80210ba437644b5b91d9bd9c564ca565a;p=gcc.git

MSP430: Support a memory operand for op1 of andneghi3

This fixes an ICE caused by an unrecognizeable insn generated when
compiling gcc.c-torture/execute/pr97386-1.c at -O0.

gcc/ChangeLog:

	* config/msp430/msp430.md (andneghi3): Allow general operand for
	op1 and update output assembler template.
