Comments
EVALUATION The fix has been verified as part of hs15-b02 pit.

PUBLIC COMMENTS Problem: The code in PhaseChaitin::Split() in the part "Handle Crossing HRP Boundry" expects that new spillCopy nodes are inserted before the current node. After 6782232 fix it is not true if the current node is CreateEx. Solution: Remove the original fix for 6782232. Move the CreateEx up before each round of IFG construction to produce correct interferences. Fix PhaseCFG::verify() and PhaseChaitin::verify_base_ptrs() methods.

EVALUATION Regression after fix for 6782232: assert("CreateEx must be first instruction in block" ). The code in PhaseChaitin::Split() in the part *** Handle Crossing HRP Boundry *** expects that new spillCopy nodes are inserted before the current node. After 6782232 fix it is not true if the current node is CreateEx.
