LLVM on Windows Now Supports PDB Debug Info

So

MSVC use PDB format which is undocumented.

LLVM want to implement PDB.

LLVM asks MS for help

MS disclose the portion of the MSVC code which deal with PDB

MS GitHub even says "Source code is the ultimate documentation :-)"

I think even the MS doesn't have formal documentation for PDB format.

This is very exciting. The blog post mentions cross-compilation, and being able to use lld should also result in faster link times and the ability to enable Clang features like CFI.

Congratulations on this milestone!

The whole idea to just change the compiler on Windows is exciting. The packages on Windows provide drop-in integration with VisualStudio.

Hopefully we will see all llvm projects ported to windows. And hopefully we can have a full toolchain, compatible/replacing Ms tools.

What about exceptions on Windows? Does LLVM support that yet?
