[Bug middle-end/32004] [4.1/4.2/4.3 regression] : can't find a register in class 'GENERAL_REGS' while reloading 'asm'

[bonzini at gnu dot org]

------- Comment #23 from bonzini at gnu dot org  2007-07-06 12:08 -------
In particular, this one could be rewritten to

inline void g(int b)
{
  register int reg = 0;
  asm volatile ("nop" : "+a"(reg), "+r"(b));
}

void f(int a)
{
  a /= 1000;
  g(a);
}

but the one in PR21291 could not.
