       2     This testcase caused ICE on SPARC because the function uses no registers
       3     after optimizing, so even if -mflat make all registers not permitted
       4     for leaf functions, the function was still leaf, but LEAF_REG_REMAP
       5     returned -1 for some registers (like %o0).  */
