[LLVMdev] inserting blocks into a Function
...us in hindsight - the PHINodes need to be updated in places where
the incoming control-edge has changed. Is there anything else that can
be affected when a block is inserted into the CFG?
Also, planning to write a helper function which will take care of such
issues. The general signature is:
void reconnectBlocks(BasicBlock *newBlock, BasicBlock *insertBefore
, std::vector<BasicBlock*> &preds
, bool createBr = true)
The std::vector "preds" is used to provide a list of preds for
insertBefore, which will be reconnected to newBlock. For cases where
