--- Comment #5 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- (In reply to Richard Biener from comment #4) > So bswap on a value is just register shuffling, right? The point is that there is no need for bswap in the first place, just have a look at the code that v13 generates. It's 4 QI loads and that's it, no shuffling required at all. But v14 dropped that, and the bswapsi (presumably due to previous flawed tree optmizations) is introduced by some tree pass. There's nothing the backend can do about it. So would you explain why you think it's a "target" issue? Maybe the PR title I used is confusing and does not hit the point?
