[Bug tree-optimization/31727] New: Functions with non-local gotos are considered not to have side effects

[rakdver at gcc dot gnu dot org]

In the following testcase with -O1, dce removes the bla call, thus
making the otherwise infinite loop terminate:

static void bla(void *label)
{
  goto *label;
}

int main (void)
{
l1:
  bla (&&l1);

  return 0;
}
