...lass to give MDInfoTy a good API and make it efficient at both small and large map sizes. Maybe s/MDInfoTy/MDMapTy/ to point out that it's a map from MDKindIds to MDNodes? Comment whether RegisterMDKind requires that its argument is as-yet-unknown in Metadata.h. Context.pImpl->TheMetadata.ValueIsDeleted(this); in ~Value will always call the empty ValueIsDeleted(Value*) overload. Please write a unittest for this. Metadata::getMDKind(Name) can just be "return MDHandlerNames.lookup(Name)" Could you comment what the WeakVH in MDPairTy is following? I got confused and thought it was tracki...

It also occurs on several (different) test cases. I have founded that assershion rises in void ValueHandleBase::ValueIsDeleted(Value *V); Code from function: // All callbacks, weak references, and assertingVHs should be dropped by now. if (V->HasValueHandle) { #ifndef NDEBUG // Only in +Asserts mode... dbgs() << "While deleting: " << *V->getType() << " %" <<...

Hi, I'm having problems with the LoopIdiomRegognizer crashing on me with An asserting value handle still pointed to this value! UNREACHABLE executed at ../lib/IR/Value.cpp:695! If I remove AU.addPreserved<LoopInfoWrapperPass>(); or AU.addPreserved<AAResultsWrapperPass>(); everything goes well. The C-code triggering this is void foo(int a[10][10]) { int i, j,

Thanks, but I replaceAllUsesWith() - works well, but I still get bug in eraseFromParent(): While deleting: i32 (%class.B*, i32)* %_ZN1B1xEi An asserting value handle still pointed to this value! UNREACHABLE executed at /Users/neonomaly/LLVM/LLVM/lib/VMCore/Value.cpp:561! Yours sincerely, Kadysev Mikhail 21.04.2012, в 23:45, Nick Lewycky написал(а): > Михаил wrote: >> How correctly
