I was just going to say: With well-formed debug info it should create a deep copy up until the DISubprogram, but no further. But because the DISubprogram linked to the Function is missing the special handling of the DISubprogram (that would prohibit cloning the DICompileUnit is side-stepped). But then I remembered the discussion we had in

The if you are cloning into the same LLVM module the CU should not cloned. If don't mind sharing your code, I can try to help diagnose why the CU gets cloned... just send me a patch that applies to trunk and instructions. -- adrian > On Jun 16, 2017, at 1:54 PM, Sergei Larin <slarin at codeaurora.org> wrote: > > Sorry… It takes a pass that was not accepted for upstreaming….
