The SSAPiInstructions do not actually introduce new control-flow, they are only markers you can use for other analyses. What are you trying to do? If they are simply in your way, you can disable them from SSAOptions.

We have two analysis, one needs the SSAPiInstructions, while the other may have a problem with them. But it is nothing we can't fix.
I just thought, that the pi instructions are inserted in the control-flow between the condition and its successors. If you "execute" the SSA form, you need to execute one of the pi-assignments, after branching. So they should introduce new control-flow, shouldn't they?

While SSAPiInstruction
s do have a reference to a basic block number, they do not influence the control-flow at all, i.e., they do not introduce any branching. You can safely simply ignore them when "executing" the SSA form in some way.

Closing as I don't think there's a bug here
