Akira Hatanaka	adaf62ced2	[Sema] Reject array element types whose sizes aren't a multiple of their ... alignments In the following code, the first element is aligned on a 16-byte boundary, but the remaining elements aren't: ``` typedef char int8_a16 __attribute__((aligned(16))); int8_a16 array[4]; ``` Currently clang doesn't reject the code, but it should since it can cause crashes at runtime. This patch also fixes assertion failures in CodeGen caused by the changes in https://reviews.llvm.org/D123649. Differential Revision: https://reviews.llvm.org/D133711	2022-09-21 09:15:03 -07:00
Richard Smith	6822bd79ac	PR26547: alignof should return ABI alignment, not preferred alignment ... Summary: - Add `UETT_PreferredAlignOf` to account for the difference between `__alignof` and `alignof` - `AlignOfType` now returns ABI alignment instead of preferred alignment iff clang-abi-compat > 7, and one uses _Alignof or alignof Patch by Nicole Mazzuca!
