Duncan Sands 212a11c417 Fix a nasty bug in LegalizeTypes (spotted in ... CodeGen/PowerPC/illegal-element-type.ll): suppose a node X is processed, and processing maps it to a node Y. Then X continues to exist in the DAG, but with no users. While processing some other node, a new node may be created that happens to be equal to X, and thus X will be reused rather than a truly new node. This can cause X to "magically reappear", and since it is in the Processed state in will not be reprocessed, so at the end of type legalization the illegal node X can still be present. The solution is to replace X with Y whenever X gets resurrected like this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47601 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-26 11:21:42 +00:00
