All releases prior to 4.5.2 contain bugs in delay slot optimization resulting in incorrect register liveness. 4.3 and 4.4 were seriously broken at -O1, and neither could bootstrap gcc at -O1. I just completed backporting all the reorg fixes that I am aware of, but they aren't included in any 4.3 or 4.4 release. It's quite possible most gcc 4.3 and 4.4 releases are miscompiled on targets with branch delay slots. As a side, all the fixes that I backported were to the generic code. I have been using 4.5.3 and haven't seen your problem. Dave -- J.
