gcc bug

[Nick Kurshev]

Hello!

All GCC versions crashes when compiling this code

int func(int a)
{
  asm("xchgb %b0,%h0":"=S"(a):"0"(a));
  return a;
}

also it crashes when compiling this code

int func(int a)
{
  asm("xchgb %b0,%h0":"=r"(a):"0"(a));
  return a;
}

wher to "=r" assigned not GENERAL CPU386 REGISTER

Best regards! Nick
