This made the testcase output depend on the specific compiler (version) used, since what was in %edx isn't strictly defined. The %edi register doesn't have a 8 byte variant. So use %edx instead to load the input word. For the CRC32 u16 (crc32w) we still use %edi because we can then use the 16 byte %di. https://bugs.kde.org/show_bug.cgi?id=438640 -- You are receiving this mail because: You are watching all bug changes.
