> MASK4 0, 5, 6, 7 also works definitely Sure :) My remark was that the tests are all(?) evenly split and a bit more variation would have been nice. Not that it doesn't work, I'm OK with it as is. Regards Robin

Re: [PATCH] RISC-V: Optimize permutation codegen with vcompress

Hi Juzhe, looks good from my side, thanks. While going through it I thought of some related cases that we could still handle differently but I didn't bother to formalize them for now. Most likely we already handle them in the shortest way anyway. I'm going to check on that when I find some time

[PATCH] RISC-V: Optimize permutation codegen with vcompress

From: Ju-Zhe Zhong This patch is to recognize specific permutation pattern which can be applied compress approach. Consider this following case: #include typedef int8_t vnx64i __attribute__ ((vector_size (64))); #define MASK_64\
