Testcase:

int foo(int X) {
 __asm__ ("frob    %0" : "+r" (X));
 return X;
}

gcc-4.6:

/var/folders/51/51Qw875vFdGa9KojoIi7Zk+++TM/-Tmp-//ccyXfgfZ.s:11:no such
instruction: `frob %eax'

clang:

<inline asm>:1:2: error: unrecognized instruction
        frob    %eax
        ^
t.c:2:11: note: generated from here
 __asm__ ("frob    %0" : "+r" (X));
          ^
