WebJul 4, 2024 · Interesting indeed ! clang can simplify both variants into bswap instruction, but makes a much worse job at inlining the "universal" variant. Even adding a force_inline statement and pushing to -O3 doesn't change the picture. That's unexpected. I would hand-waive that it could be a consequence of optimization pass order. Anyway, this is a good …
