Duncan Sands 47d9dcc584 Fix PR3117: not all nodes being legalized. The ... essential problem was that the DAG can contain random unused nodes which were never analyzed. When remapping a value of a node being processed, such a node may become used and need to be analyzed; however due to operands being transformed during analysis the node may morph into a different one. Users of the morphing node need to be updated, and this wasn't happening. While there I added a bunch of documentation and sanity checks, so I (or some other poor soul) won't have to scratch their head over this stuff so long trying to remember how it was all supposed to work next time some obscure problem pops up! The extra sanity checking exposed a few places where invariants weren't being preserved, so those are fixed too. Since some of the sanity checking is expensive, I added a flag to turn it on. It is also turned on when building with ENABLE_EXPENSIVE_CHECKS=1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60797 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-09 21:33:20 +00:00
