2027 2. The value is already known in this block, graph_arr[pos] is set and we
2028 visit the block the first time. We can return the value without
2029 creating any new nodes.
2031 3. The block is mature and we visit it the first time. A Phi node needs
2032 to be created (phi_merge). If the Phi is not needed, as all it's
2033 operands are the same value reaching the block through different
2034 paths, it's optimized away and the value itself is returned.
2036 4. The block is mature, and we visit it the second time. Now two
2037 subcases are possible:
2038 * The value was computed completely the last time we were here. This
2039 is the case if there is no loop. We can return the proper value.
2040 * The recursion that visited this node and set the flag did not
2041 return yet. We are computing a value in a loop and need to
2042 break the recursion without knowing the result yet.
2043 @@@ strange case. Straight forward we would create a Phi before
2044 starting the computation of it's predecessors. In this case we will
2045 find a Phi here in any case. The problem is that this implementation
2046 only creates a Phi after computing the predecessors, so that it is
2047 hard to compute self references of this Phi. @@@
2048 There is no simple check for the second subcase. Therefore we check
2049 for a second visit and treat all such cases as the second subcase.
2050 Anyways, the basic situation is the same: we reached a block
2051 on two paths without finding a definition of the value: No Phi
2052 nodes are needed on both paths.
2053 We return this information "Two paths, no Phi needed" by a very tricky
2054 implementation that relies on the fact that an obstack is a stack and
2055 will return a node with the same address on different allocations.
2056 Look also at phi_merge and new_rd_phi_in to understand this.
