--- Comment #8 from gidici61 at gmail dot com --- (In reply to H.J. Lu from comment #7) > Since GCC finds out that g2 only needs 8 byte stack alignment, > it only needs to align stack to 8 byte when calling g2. Thank you. So this should be an exception? System V ABI x86, par. 3.2.2, page 16, says: "The end of the input argument area shall be aligned on a 16 (32, if is passed on stack) byte boundary. In other words, the value (%rsp + 8) is always a multiple of 16 (32) when control is transferred to the function entry point".
