VERY BUSY EXPRESSIONS


						
				void flowvbe(
				
  ref dmd.backend.goh.GlobalOptimizer go
				

				) nothrow @trusted;

Compute very busy expressions(VBEs). That is,expressions that are evaluated along separate paths. Bin = the set of VBEs at the beginning of B. Bout = the set of VBEs at the end of B. Bgen = set of expressions X+Y such that X+Y is evaluated before any def of X or Y. Bkill = set of expressions X+Y such that X or Y could be defined before X+Y is computed. Note that gen and kill are mutually exclusive.
