Errr, why you just mixed in JuZhe’s patch set into this patch set? Michael Collison 於 2023年5月5日 週五，23:47寫道： > This series of patches adds foundational support for RISC-V > auto-vectorization support. These patches are based on the current upstream > rvv vector intrinsic support and is not a new implementation. Most of the > implementation consists of adding the new vector cost model, the > autovectorization patterns themselves and target hooks.
