Hello, I'm having this assertion fail when I was using DIBuilder to create the debug information: Expected no forward declarations! !719 The assertion condition is: !isa<MDNodeFwdDecl> (MD) So My questions are: 1. What is exactly the MDNodeFwdDecl ? I saw it's in the latest release 3.6.1, but I also found this link http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150119/253730.html saying that MDNodeFwdDecl has been removed, and neither can I find class refe...

Hello everyone, If I understand correctly after the Metadata/Value split the Metadata support of RAUW is limited by ValueAsMetadata and MDNodeFwdDecl (i.e. until cycled in MDNode are not resovled). And my question is. Is where any way to replace an MDNode which is referenced by other MDNodes w\o iterating over all MDNodes in LLMVContext to find and replace those references? Unfortunately I couldn't find such example in LLVM source code... B...

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

It's now a multi-stage process. First, there is a difference between a permanent forward declaration (i.e. the actual definition is in a different file) and a temporary forward declaration (i.e. it will appear later in the same file). To create a permanent forward declaration: DICompositeType *result = m_DIBuilder->createForwardDecl( dwarf::DW_TAG_structure_type,

Before metadata was separated from values, I could create a debug info forward declaration and eventually resolve it using LLVMReplaceAllUsesWith in core.h. Now, I can't figure out how to resolve it. I can find no function that seems to do this. My one wild guess that giving the forward decl and the resolving decl the same UniqueId might do it is not working. I am currently using 3.6.1, but
