Probably not. > Things worked before and stay working, nothing user-visible? Except for bad user asm() that ought to be true. Oh, and gcc bugs like emitting power9 insns when -mcpu=power8. You'd have some chance that the assembler would complain rather than getting sigill at run-time. -- Alan Modra Australia Development Lab, IBM
