llvm dev - Apr 2015 - [LLVMdev] PDB support in LLVM

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?

Not today.

Zach (CC-ed) and others are actively working on making LLDB work well on
Windows, including reading DWARF debug information on Windows and
potentially integration with Visual Studio (although I think that is
further away at the moment). However, further discussion might be better on
the LLDB mailing lists.

Personally, I suspect the best way to do this is to write DWARF and get
LLDB into your workflow (either directly with the command line or in the
IDE). That at least is the path others are currently pursuing.

It's worth pointing out that CodeView is **not** only for line information.
It's for everything.  It's just that LLVM currently only understands a
subset of CodeView record types related to line information.
