Subject: [Bug optimization/14135] New: No sibcalling for some obvious places (happens in java's front-end)
X-Bugzilla-Reason: CC

List-Id: <gcc-bugs.sourceware.org>

The function, f, should just have a sibcalling to t and should be the same as function, g.
This is derived from the java front-end (java_tree_inlining_walk_subtrees, case BLOCK).

int t(int);
int f(int i)
{
  int result;
  result = t(i);
  if (result)
    return result;
  return 0;
}
int g(int i)
{
  return t(i);
}
