--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
By the way, the following:

double f(double x){
  asm volatile("":"+X"(x));
  return x;
}
double g(){
  return f(1.);
}

is rejected with:

c.c: In function 'g':
c.c:2:3: error: inconsistent operand constraints in an 'asm'
   asm volatile("":"+X"(x));
