I am trying to implement an optimization in IonMonkey that consists in removing unreachable basic blocks. However, I am having problems to implement it, because I do not know how to update the phi-functions once I remove a block. For instance, if I have this program:
Just by curiosity, what is your final project ? I don't think IonMonkey is producing headless basic block except for entry points. Removing dead basic block is something that we will need when we would have optimizations manipulating the graph.
L0: v0 = 0 goto L2 L1: v1 = 1 L2: v2 = phi(v0, v1) print v2 I want to eliminate L1, and then the program would be like:
Take care, you will need to ensure that the block you are trying to remove is not the OSR block created when we are compiling with canEnterAtBranch.
