1227 node the caller _will_ allocate. (Yes, we predict the address. We can

1360 predecessors is returned. This node is added to the linked list (field

1362 matured. (Completion will add a new Phi and turn the Phi0 into an Id
1365 2. The value is already known in this block, graph_arr[pos] is set and we
1366 visit the block the first time. We can return the value without
1367 creating any new nodes.
1369 3. The block is mature and we visit it the first time. A Phi node needs
1370 to be created (phi_merge). If the Phi is not needed, as all it's
1371 operands are the same value reaching the block through different
1372 paths, it's optimized away and the value itself is returned.
1374 4. The block is mature, and we visit it the second time. Now two
1375 subcases are possible:
1376 * The value was computed completely the last time we were here. This
1377 is the case if there is no loop. We can return the proper value.
1378 * The recursion that visited this node and set the flag did not
1379 return yet. We are computing a value in a loop and need to
1380 break the recursion without knowing the result yet.
1381 @@@ strange case. Straight forward we would create a Phi before
1382 starting the computation of it's predecessors. In this case we will
1383 find a Phi here in any case. The problem is that this implementation
1384 only creates a Phi after computing the predecessors, so that it is
1385 hard to compute self references of this Phi. @@@
1386 There is no simple check for the second subcase. Therefore we check
1387 for a second visit and treat all such cases as the second subcase.
1388 Anyways, the basic situation is the same: we reached a block
1389 on two paths without finding a definition of the value: No Phi
1390 nodes are needed on both paths.
1391 We return this information "Two paths, no Phi needed" by a very tricky
1392 implementation that relies on the fact that an obstack is a stack and
1393 will return a node with the same address on different allocations.
1394 Look also at phi_merge and new_rd_phi_in to understand this.
