About

557.xz has a couple hot loops that have a data dependent early exit. AArch64 has a dedicated pass to manually vectorize these loops. More discussion here https://discourse.llvm.org/t/aarch64-target-specific-loop-idiom-recognition/72383 This project is to port this pass to RISC-V while sharing as much code as possible.
