I'll add a patch to fix this by having dummy.c print an > explicit magic string, e.g. Dummy Hello World!. > powerpc and s390x always exit with printf("\nEXIT: STATUS=%d\n", ((code) << 1) | 1); It's because they can only exit with exit code zero, but maybe it's worth adopting the same line and format for EFI tests?
