If we'd enable a 16 byte aligned stack, clang/llvm would also assume that alignment everywhere and produce code that strictly requires it. That would require adding realignment (via attribute_align_arg) on every single public library function or enable -mstackrealign (which does the same on every single function). Also relatedly; the parameter currently tested (-mllvm -stack-alignment=16) hasn't actually been supported for quite some time; current clang versions use -mstack-alignment=16 for the same. Actually testing for that parameter would be a different change though, since it has a real risk of changing behaviour on any other platform where clang is used.
