llvm dev - Mar 2018 - [PDB] [JIT] Write to PDB file when COFFObjectFile is emitted by JIT

Is it possible to write a .pdb file containing the debug info stored in a
COFFObjectFile once the NotifyObjectEmitted is triggered by the JIT
compiler ?

Hi Vivien,

I'm not familiar with Windows development, but I believe you could dump the
object file to disk then run LINK.EXE to produce the PDB. Alternatively, I
think LLD can also produce PDB files (Rui -- is that right?), in which case
you may be able to use that.

Is the aim to be able to debug JIT'd code? Which debugger do you plan to
use?

-- Lang.

Yes, lld can produce PDB files.
