Insert padding in __cxa_exception struct for compatibility Similar to https://github.com/llvm/llvm-project/commit/f2a436058fcb, the addition of __attribute__((__aligned__)) to _Unwind_Exception (in commit b9616964) causes implicit padding to be inserted before the unwindHeader field in __cxa_exception. Applications attempt to get at the earlier fields in __cxa_exception, so preserve the same negative offsets in __cxa_exception, by moving the padding to the beginning of the struct. The assumption here is that if the ABI is not aware of the padding before unwindHeader and put the referenceCount/primaryException in there, no padding should exist before unwindHeader. This should make libreoffice's custom exception handling mechanisms work correctly, even if it was built against an older cxxabi.h/unwind.h pair. PR: 263370 MFC after: 3 days |
