split_flow_path can create irreducible loops

XMLWordPrintable

    • Cause Known

      split_flow_path in cfgnode.cpp blindly rearranges edges which can in some cases create irreducible loops. This optimization should either try to figure out if it's rearranging backedges or should be done in loop opts when that information is available. It appears to be the only remaining case where we create irreducible loops during optimization.
