Jakub Jelinek 041f741770 libffi: Fix up x86_64 classify_argument ... As the following testcase shows, libffi didn't handle properly classify_arguments of structures at byte offsets not divisible by UNITS_PER_WORD. The following patch adjusts it to match what config/i386/ classify_argument does for that and also ports the PR38781 fix there (the second chunk). This has been committed to upstream libffi already: 5651bea284 2021-06-16 Jakub Jelinek <jakub@redhat.com> * src/x86/ffi64.c (classify_argument): For FFI_TYPE_STRUCT set words to number of words needed for type->size + byte_offset bytes rather than just type->size bytes. Compute pos before the loop and check total size of the structure. * testsuite/libffi.call/nested_struct12.c: New test.		2021-06-16 10:45:27 +02:00
