There is a comment at the top of DAGTypeLegalizer::PerformExpensiveChecks which, in part, says: // Note that these invariants may not hold momentarily when processing a node: // the node being processed may be put in a map before being marked Processed. Unfortunately, this assert would be valid only if the above-mentioned invariant held unconditionally. This was causing llc to assert when, in fact, everything was fine. Thanks to Richard Sandiford for investigating this issue! Fixes PR16562. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186338 91177308-0d34-0410-b5e6-96231b3b80d8
