It does not seem so: $ /qemu-s390x-new -version qemu-s390x version 2.12.50 (v2.12.0-1983-g7de3b1cdc6-dirty) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers $ /qemu-s390x-new ./a.out Istruzione non consentita (i.e., "illegal instruction") But this might be expected. Now I go to the previous commit (f777b20544) and recompile: $ /qemu-s390x-new -version qemu-s390x version 2.12.50 (v2.12.0-1982-gf777b20544-dirty) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers $ /qemu-s390x-new ./a.out Istruzione non consentita So again. And even going back to 76ed4b18de (i.e., skipping a few apparently related s390x commits): $ /qemu-s390x-new -version qemu-s390x version 2.12.50 (v2.12.0-1976-g76ed4b18de-dirty) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers $ /qemu-s390x-new ./a.out Istruzione non consentita > stckf will end up at the same helper, so it seems likely to hit the > same problem. I guessed so.
