edge splitting can cause new basic blocks to be added to the graph, but while the graph itself gets properly rewritten the descriptor tables can't be updated to take these into account, so they end up pointing at the wrong blocks. This causes really hard-to-debug problems. The new approach is to parse the descriptor blocks and then generate a comparison chain. Brute force, but much easier for the compiler to reason about. |
