Overview
| Comment: | Stop constant folding from leaving dead code behind, Add a test for simple nested iterations, using [lmap]. Temporarily patch 'foreach' operations from being hoistable - I don't think this will be necessary, but it's tickling other bugs. Make translation of values across a phi work if one of the inputs to the phi is a literal. Put 'bbidom' and 'bblevel' directly after dead code elimination, because virtually everything depends on having dominators, which deadcode destroys. |

| 05:37 | Rewrite pre_insert and pre_phi_translate to NOT use a persistent cache. The missing piece in VanD04 is that pre_insert must call pre_phi_translate for all the anticipated expressions first, and then use the dictionary that results for the translated values. There are still further bugs, but we're over this hump at least. check-in: 0bbe5a5dd3 user: kbk tags: notworking, kbk-pre | |

| 01:06 | Fix crashing bug in creating variable name for a phi operation. Fix bug where partial redundancy elimination got stale dominators, causing much weirdness. Add additional tracing to available expression calculation. check-in: ce1088b7a7 user: kbk tags: notworking, kbk-pre | |
