llvm dev - Sep 2014 - [LLVMdev] codeview debug info in Visual Studio

Hi,

Is there any way to debug the codeview output of llvm from within Visual  
Studio?

I want to use the codeview line info debug output of clang/llvm. I tried  
with the
x86_64-pc-windows-msvc and i686-pc-windows-msvc triples and linking it  
into an
existing project with VC++ from within the IDE and outside with link  
/debug.
Neither option lets me debug with Visual Studio as debugger host. With  
some help
I found that WinDBG does show line info, but Visual Studio does not, is  
there any
way to get this working with VS?

Hm, this didn't work out of the box for me.

Make sure the debug info format is set to one of /Zi or /Z7. /ZI (capital
'i') is ignored, but it looks like it's the default. We may wish to
revisit
that. You can find that setting in project -> properties -> C/C++ ->
debug
information format.

Once I did that, I got symbols, but no line info. The source language was
listed as "unknown", so we may need to do a thing or two to make VS
happy.

Hi Carlo,

Do you have VS2010 handy?  It should read the DI fine.

Unfortunately, VS2013 is not able to use the debug info we generate.
It is on my plans to investigate and fix the generator, but I didn't have
enough free cycles recently.
