This method is quite large (about 13000 instruction), but contains only about 1200 labels (jump targets), i can't belive that they are called in 1 single chain. In visitcode the IfType instuctions are recursively visited before visiting the instructions in the current flow. Maybe it would be better to fisrt check the instuctions in the current flow. I mean: ins1 ins2 ifxx label2 ins4 ins5 label2: ins6 ins7 Currently the order is: ins1, ins2, ifxx, (recursive call) ins6, ins7 (return), ins4. ins5 In the suggested way: ins1, ins2, ifxx, ins4, ins5, ins6, ins7 (now check the "ifxx" target, but it is already processed) For this you need to collect the possible targets to a list. Or iterate 2 times on the instuction list. First only mark the instuctions in the current flow only, do not jump anywhere, 2nd time is the current implementation.
