Is making PDB files for corresponding IR supported in LLVM latest version? After some searching I see llvm-pdbdump, but I want to annotate the IR with debug information so that when I write bitcode it has pdb information. I've heard of CodeView, but it seems to be only for line information. I want variable values also. I would be ok to use DWARF if Visual Studio could understand it using LLDB but I don't know how to do that or if it is support. I would also be ok to write DWARF and then convert to PDB if such is possible. How can I achieve this? -------------- next part -------------- An HTML attachment was scrubbed...

That at least is the path others are currently pursuing. -------------- next part -------------- An HTML attachment was scrubbed...

It's just that LLVM currently only understands a subset of CodeView record types related to line information. -------------- next part -------------- An HTML attachment was scrubbed...
