Also, like kito previous remind me: https://gcc.gnu.org/pipermail/gcc-patches/2023-November/635326.html
I think you should add a dedicated test which with specifying -march=rv64gcv_zbb, then scan-assembler-check the correct vsetvl. So that we can allow people like me be able to avoid regression of such issue even if I didn't build toolchain with "zbb". juzhe.zh...@rivai.ai From: Robin Dapp Date: 2023-11-13 16:12 To: juzhe.zh...@rivai.ai; gcc-patches; palmer; kito.cheng; jeffreyalaw CC: rdapp.gcc Subject: Re: [PATCH] RISC-V: vsetvl: Refine REG_EQUAL equality. > Does this patch fixes exposed bugs in current tests? > Or could you add test for it ? Ah, yes forgot to mention. This fixes several tests when testing with -march=rv64gcv_zbb. Regards Robin
