Pseudo-Dominator Blocks

  • Although it was not feasible to spend time converting the code into SSA form, the framework for building dominator blocks was already in place.
  • The only reason SSA is needed is due to phi functions for value numbers killed in predecessors between the current block and its immediate dominator
  • We can simply ignore killed value numbers, but still import all "untouched" value numbers from the block's immediate dominator
