Function dmd.backend.gflow.flowcp


extern(C++) void flowcp() nothrow @trusted;

Compute copy propagation info (CPs). Very similar to AEs (the same code is used). Using RDs for copy propagation is WRONG! That is, set of copy statements still valid. Bin = the set of CPs reaching the beginning of B. Bout = the set of CPs reaching the end of B.
