r276215 made a change to annotate _Unwind_Exception with attribute "aligned" so that an exception object following field __cxa_exception is sufficiently aligned. This fix hasn't been incorporated to unwind.h on Darwin since it is an ABI breaking change. Instead of annotating struct _Unwind_Exception with the attribute, this commit annotates field unwindHeader of __cxa_exception. This ensures the exception object is sufficiently aligned without breaking the ABI. This recommits r302978 and r302981, which were reverted in r303016 because a libcxx test was failing on an AArch64 bot. I also modified the libcxxabi test case to check the alignment of the pointer returned by __cxa_allocate_exception rather than compiling the test with -O1 and checking whether it segfaults. rdar://problem/25364625 Differential Revision: https://reviews.llvm.org/D33030 llvm-svn: 303175 |
