| | | | | | | | | | | | | | | | | | | | | ReadyToProcess node - add an assertion to check this. Add an assertion to NodeDeleted that checks that processed/ready nodes are indeed not deleted. It is because they are never deleted that none of the maps can have a deleted node as the source of a mapping. It does however seem to be possible in theory to have a deleted value as the target of a mapping, however this has not yet been spotted in the wild. Still mulling on what to do about this. [The theoretical situation is this: a node A is expanded/promoted/whatever to a newly created node B. Thus A->B is added to a map. When the subtree rooted at B is legalized it is conceivable that B is deleted due to RAUW on a node somewhere above it]. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46705 91177308-0d34-0410-b5e6-96231b3b80d8
