It seems unlikely to be needed, but if it ever is, we want to get an assert instead of silent bad codegen. llvm-svn: 30716 --- llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp b/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp index 71746e2b6edf..d4e186cabb2c 100644 --- a/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp +++ b/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp @@ -253,11 +253,9 @@ bool llvm::SplitCriticalEdge(TerminatorInst *TI, unsigned SuccNum, Pass *P) { if (DominanceFrontier *DF = P->getAnalysisToUpdate()) { // If NewBBDominatesDestBB hasn't been computed yet, do so with DF. if (!OtherPreds.empty()) { -#if 0 // FIXME: IMPLEMENT THIS! - OtherPreds.clear(); -#endif - NewBBDominatesDestBB = false; + assert(0 && "Requiring domfrontiers but not idom/domtree/domset." + " not implemented yet!"); } // Since the new block is dominated by its only predecessor TIBB,
