Changing the code leads to different errors like:



int __RTL (startwith ("rtl-dfinit")) times_two (int i)
{
  /* C function:
     return i * 64;  */
(function "times_two"
  (insn-chain
    (cnote 2 NOTE_INSN_DELETED)
    (block 32768
      (edge-from entry (flags "FALLTHRU"))    
    ) ;; block 3
  ) ;; insn-chain
  (crtl
    (return_rtx
      (reg/i:SI ax)
    ) ;; return_rtx
  ) ;; crtl
) ;; function "times_two"
}

int main(void) {}
