TempMap, and not Appel?See $fp or fp, for all the details. Pay special attention to converting the temporaries where needed:
- − the flow graph is independent of the temporaries
- − the liveness graph, when computing live-in and live-out sets, must of course convert the “def” and “use” sets
- − the interference graph, when attributing a node number for each
temporary (
InterferenceGraph::node_of), must allocate the same number to corresponding temporaries (e.g., ‘$fp’ and ‘fp’ must bear the same number).
There is another reason to use a TempMap here: to build the
liveness graph after register allocation, to check the compiler.
