Valgrind does not require that the host machine has the same hardware
facilities as the machine for which the client program was compiled.

This means, though, that probing for hardware facilities by issuing
instructions from that facility and observing whether SIGILL is thrown
may not work. As a consequence, programs that attempt to do so may
