C++ (Cpp) fast_out Examples

Example #1

File: machnode.cpp Project: gaoxiaojun/dync

bool MachCallNode::return_value_is_used() const {
  if (tf()->range()->cnt() == TypeFunc::Parms) {
    // void return
    return false;
  }

  // find the projection corresponding to the return value
  for (DUIterator_Fast imax, i = fast_outs(imax); i < imax; i++) {
    Node *use = fast_out(i);
    if (!use->is_Proj()) continue;
    if (use->as_Proj()->_con == TypeFunc::Parms) {
      return true;
    }
  }
  return false;
}

Example #2

File: multnode.cpp Project: stkaushal/jdk8_tl

//------------------------------proj_out---------------------------------------
// Get a named projection

  assert(Opcode() != Op_If || which_proj == (uint)true || which_proj == (uint)false, "must be 1 or 0");

  for( DUIterator_Fast imax, i = fast_outs(imax); i < imax; i++ ) {
    Node *p = fast_out(i);
    if( !p->is_Proj() ) {
      assert(p == this && this->is_Start(), "else must be proj");
      continue;
    }
    ProjNode *proj = p->as_Proj();
    if( proj->_con == which_proj ) {
      assert(Opcode() != Op_If || proj->Opcode() == (which_proj?Op_IfTrue:Op_IfFalse), "bad if #2");
      return proj;
