Hi Sun, Could you please review the code for WHIRL CFG verfier and 1 bug fix for WHIRL SSA in mainopt emitter? Thank you very much. The WHIRL CFG verifier shares the same traversal code with the WHIRL CFG builder to verify the CFG. The bug fix for WHIRL SSA in MainOPT emitter is to remove duplicated phi/chi/mu node of the same symbol attached on the same whirl node. This case happens when two WOPT stmbol entries are mapping to one symbol in WHIRL SSA.
The patch is attached. Thank you very much. -- Regards, Lai Jian-Xin
