[Bug target/38941] CX isn't preserved with shift

How about this one:

---
extern void abort (void);

void
foo (int x)
{
  if (x != 8)
    abort ();
}

void
bar (int g)
{
    register int x __asm__("ecx");
    register int y __asm__("eax");
    x = 5;
    foo (1 << g);
    asm ("mov %1, %0": "=r" (y): "r" (x));
    if (x != 5)
      abort ();
    if (y != 5)
      abort ();
}

int
main ()
{
  bar (3);
  return 0;
}
