Really it is, it is valuable to me (it can generate the correct > insns for comparing).

For removing "-fno-reorder-blocks", it is passed compiling, but we should check the assembly output too: hwloop_optimize() generates almost the same insns just like having "-fno-reorder-blocks", but it is passed compiling. The related full insns for removing "-fno-reorder-blocks" are in the next attachment.
