Yes, it's a cleanup. juzhe.zhong@rivai.ai From: Jeff Law Date: 2022-11-29 00:48 To: juzhe.zhong; gcc-patches CC: kito.cheng; palmer Subject: Re: [PATCH] RISC-V: Remove tail && mask policy operand for vmclr, vmset, vmld, vmst On 11/28/22 07:21, juzhe.zhong@rivai.ai wrote: > From: Ju-Zhe Zhong <juzhe.zhong@rivai.ai> > > Since mask instruction doesn't need policy, so remove it to make it look reasonable. > gcc/ChangeLog: > > * config/riscv/vector.md: Remove TA && MA operands.
