stmt-expr-label-1.c

用于进行gcc测试

/* Test for labels in statement expressions: bugs 772 and 17913.
   goto statements must not jump into statement expressions.

   This tests all combinations of label and goto locations in a given
   function.  Each combination is tested twice, once with just that
   label and goto and once with many others in order to exercise the
   different code paths involved with excess labels.  */
