search for: valuemap

Hi there, I added a function to a module, but failed to write the bitcode to file because it hit the: assert(I != ValueMap.end() && "Value not in slotcalculator!") So I added some diagnosis information there, unsigned ValueEnumerator::getValueID(const Value *V) const { if (isa<MDNode>(V) || isa<MDString>(V)) { ValueMapType::const_iterator I = MDValueMap.find(V); assert(I !=...

...e to a Value pointing into the new one. The CloneModule implementation already has to keep such a mapping internally, so I've written a patch that exposes it as a second inout parameter to CloneModule(), with the one param version being a simple wrapper for backward compatibility. The type of ValueMap is std::map<const Value *, Value*> and the semantics are simply: Value *New = ValueMap[Old]; Nick Lewycky -------------- next part -------------- A non-text attachment was scrubbed...

Hi, I have a question about llvm/ADT/DenseMap.h and llvm/IR/ValueMap.h: When you have a: MapType M; is it safe to do: M[NewKey] = M[OldKey]; or do you need to do it in two steps: auto tmp = M[OldKey]; // ensure the reference to M[OldKey] is copied, before reassigning. M[NewKey] = tmp; // might reallocate aka, will a possible allocation for M...

Hi, I'm gonna try to give some feedback, but I have only been working with LLVM for a few days, so don't take what I'm saying without verifying :-) > BasicBlock *ProgSlicer::CloneBasicBlock(const BasicBlock *BB, > DenseMap<const Value*, Value*> &ValueMap, > const char *NameSuffix, Function *F) { > > BasicBlock *NewBB = new BasicBlock("", F); > if (BB->hasName()) NewBB->setName(BB->getName()+NameSuffix); > > bool hasCalls = false, hasDynamicAllocas = false, > has...

Hi Guoliang, > I added a function to a module, but failed to write the bitcode to file > because it hit the: > assert(I != ValueMap.end()&& "Value not in slotcalculator!") does the module pass the verifier after you add the function to it? Ciao, Duncan.

The `Metadata`/`Value` split (PR21532) landed in r223802 -- at least, the C++ side of it. This was a rocky day, but I suppose that's what I get for failing to stage the change in smaller pieces. As of r223916 (lldb), I'm not aware of any remaining (in-tree) breakage, so if I've missed some problem in the sea of buildbot errors, please flag me down. I'll follow up soon with

This will help us generate new LLVM tests we can send upstream. We've fixed bugs that aren't caught by the upstream tests and it would be nice to capture the problem and make the test

...eturned from getLinkedToGlobal(SGV) and assigned to DGV. However, as ForAlias is true and ShouldLink is false, DGV becomes nullptr later, and NewGV is created from copyGlobalValueProto(SGV, ShouldLink) call. Therefore, returned value from linkGlobalValueProto is different from the value obtained by ValueMap.lookup(SGV) in IRLinker::materialize. BTW, I updated LLVM to the latest version in SVN this morning, and the assertion failure is gone. Instead, it ends up with broken module found errors: Global is external, but doesn't have external or weak linkage! void (%2*, %2*, i32)* @"_foo.llvm.E5...
