--- Comment #32 from JuzheZhong <juzhe.zhong at rivai dot ai> --- 26% time reduction seems not enough. Maybe we still need to optimize MD patterns to fix this issue ? But I have no idea to optimize it since I already tried my best to reduce them. According to RVV intrinsic doc: https://github.com/riscv-non-isa/rvv-intrinsic-doc we have these 6 types variant intrinsics: __vop __vop_tu __vop_mu __vop_tum __vop_tumu __vop_m I have fused them into same pattern (which makes the pattern so complicated) to avoid explosion of MD patterns (otherwise, it will explode 6 times if we dedicate each type intrinsic one MD pattern). But seems it's still an issue. And I have no idea how to reduce them.
