Method Detail

getPhi

protected <T> PhiNode getPhi(T virtual,
                             Stamp stamp)

merge

protected void merge(List<BlockT> statesList)

Merge all predecessor block states into one block state. This is an iterative process, because merging states can lead to materializations which make previous parts of the merging operation invalid. The merging process is executed until a stable state has been reached. This method needs to be careful to place the effects of the merging operation into the correct blocks.

Specified by:

merge in class EffectsClosure.MergeProcessor

Parameters:

statesList - the predecessor block states of the merge
