Subject: Re: [COMMITTED] bpf: fixed template for neg (added second operand)
Date: Fri, 21 Jul 2023 19:40:20 +0100 [thread overview]
Message-ID: <87jzut3y7f.fsf@oracle.com> (raw)
In-Reply-To: <87lef95ecv.fsf@oracle.com>
This patch fixes define_insn for "neg" to support 2 operands.
Initial implementation assumed the format "neg %0" while the instruction
allows both a destination and source operands. The second operand can
either be a register or an immediate value.
gcc/ChangeLog:
* config/bpf/bpf.md: fixed template for neg instruction.
