At a high-level, my only real request is that you think hard about adding asserts to the rename logic (esp. the freelist and maptable). I was too lazy and complacent to do so before, but I think now is a good time to do so while the logic is fresh in your mind.

@bkorpan bkorpan force-pushed the rename-refactor-rebased branch 4 times, most recently from 7dece28 to ee7a548 Compare June 23, 2019 19:57
…se where a branch at the rob tail could mispredict during the first cycle of rollback. This bug was also present prior to this refactor. This is the best fix because it should not affect the speed of the branch/exception kill paths, and might also enable a future QoR tweak.

This should be ready to go now. I'll do another check that it boots Fedora after this big round of tweaks.

Boots Fedora fine with 2, 3, and even 4 -wide pipelines.
