When lowering a struct type to an LLVM struct type, keep track of whether there are any underaligned fields. If so, then make it a packed llvm struct. This works because we already insert manual padding bytes regardless. We could unconditionally use an LLVM packed struct; the reason we bother checking for underaligned fields is that it is a conservative choice, in case LLVM handles packed structs less optimally. A future improvement could simplify this code by unconditionally using packed LLVM structs and then make sure measure perf is unaffected. closes #12190 |
