So I tested against lld, gold, and ld, and they all seem to end up with `int`-typed GVs having a filesize of 32 bytes and an ELF `st_size` of 4 bytes, and the runtime seems okay, but I think this breaks ELF rules:

I suspect this could break relinkers and various other things. It doesn't seem clear to me *why* amdgpu has problems with copying the extra redzone padding. We may also actually use the redzone for metadata and would expect that it would be consistent. https://github.com/llvm/llvm-project/pull/66666 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
