My question is, should we care about ILP32 for > SVE? If so we need to fix this. Otherwise, we can run the test for LP64. We care, but I don't think anyone's actively working on it. I agree it's a generic ILP32 problem though. We already disable scan-assembler matching in sve/ for similar reasons, so I think the easiest fix is to move both pr88834.c and pr88838.c from aarch64/ to aarch64/sve/. Sorry for not noticing that they were in the "wrong" directory during the reviews. Note that after moving, the dg-options for both tests should just be "-O3", without "-S" or "-march=...".
