...e IR looks generally right. However, if I run dwarfdump on my object file, I'm not seeing any DIE information for the local variables. I'm wondering what might be going wrong along the way. [...] To follow up after some debugging and more digging, it turns out that I hadn't created a DILexicalBlock for my function and then the variables were getting silently dropped; I had assumed that the DISubprogram would be enough and that the DILexicalBlock was only necessary for inner scopes. With that, it all works swimmingly so far. Thanks, -matt

Hello, I need to know how I get the LLVM::IDScope object of an instruction. My program contains: call void (...)* @commit(), !dbg !16 !16 = metadata !{i32 16, i32 5, metadata !8, null} !8 = metadata !{i32 589835, metadata !4, i32 10, i32 1, metadata !2, i32 0} ; [ DW_TAG_lexical_block ] LLVM::Instruction.hasMetadata() is 0 I got LLVM::Scope for variables over DIGlobalVariable.getContext()

I know. I am writing an LLVM pass and I do not know how I get a hand on the DIScope object. Which method(s) of the LLVM C++ API do I have to call to get a pointer or reference (!8) to the LLVM::DIScope of an LLVM::Instruction? Christian

...h (still working on testcase update script logic I believe (probably other details, don't let me oversell it)). 3. Create a special `METADATA_SUBPROGRAM_BLOCK` for each `DISubprogram` in the global metadata block. Store the relevant `DISubprogram` and all of the subprogram's `DILexicalBlock`s and `DILocalVariable`s. The block can be lazy-loaded on an all-or-nothing basis. In combination with (2), this addresses (a) and (b) in cases that (1) doesn't catch. A lazy-loading module will only load the subprogram blocks that get referenced. (I have a basic design f...
