--- Comment #8 from Linus Torvalds <torva...@linux-foundation.org> --- (In reply to Alexander Monakov from comment #7) > > Most likely the issue is that sout/sfrom are misaligned at runtime, while > the vectorized code somewhere relies on them being sufficiently aligned for > a 'short'. They absolutely are. And we build the kernel with -Wno-strict-aliasing exactly to make sure the compiler doesn't think that "oh, I can make aliasing decisions based on type information". Because we have those kinds of issues all over, and we know which architectures support unaligned loads etc, and all the tricks with "memcpy()" and unions make for entirely unreadable code. So please fix the aliasing logic to not be type-based when people explicitly tell you not to do that. Linus
