> #current bpv=24 gets vectorized on the shift loop, but not for the remainder loop. This is an interesting observation. I wonder if a small refactoring could help it get auto-vectorized? E.g. what if we applied the `0xFF` mask to `scratch` in the shift loop rather than the remainder loop? Or if we split the remainder loop into 3 loops, one for each 8 bits that get contributed to the value? Sorry for pushing, but if we could get auto-vectorization to do the right thing, then this would automatically benefit all users, not only those who enable the vector module. -- This is an automated message from the Apache Git Service.
