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

If so, can you point me to a description of how I should change our code? Should I bug someone else about this problem? Should this API change be documented in

I'm upgrading my application to use LLVM 3.7.1 instead of 3.5.1. On one of my regression tests I am getting an assertion: /home2/djones/llvm-3.7.1.src/lib/IR/Metadata.cpp:490: void llvm::MDNode::resolve(): Assertion `isUniqued() && "Expected this to be uniqued"' failed. This occurs when finalizing debug info prior to code generation: #4 0x00007ffff4520455 in

Hello Everyone, I would like to have your thoughts on this. Overview of the problem =================== While implementing support for the DWARFv5 debug_macro section support in LLVM. I came across these holes: - The macros infrastructure in CLANG/LLVM is inherently tied to a particular version(v4 macinfo). For instance, consider this snippet from CLANG:
