[PATCH] D110933: [RISCV] Add a test showing incorrect RVV stack alignment

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

So I'm not 100% sure yet, but this alignment bug may well also apply to certain scalar (well, non-scalable-vector) stack objects if there's a non-zero RVV stack size and they're on the "wrong" size of the RVV section from whichever frame register we're using.

I still haven't found the right fix for this. Do we have to track the maximum vector-object alignment separately to minimize changes on generated code that doesn't need vector alignment larger than 8 bytes?
