Do you just need a pdb, or does it really need to be a vs pdb? lld can
generate high quality pdbs now. So it might be possible to use lld to link
and produce a pdb when you run the test.
Pavel’s suggestion is equally viable, you can dump a pdb to yaml and
convert it back to a pdb at test time.
The real problem is the exe. It’s harder to generate exes at test time
because we have to ensure that dependent libraries are present on the
If it has to be an msvc generated pdb, can you elaborate on why? Tbh I’m
not really against checking in pdbs. Exes I’d like to find a way to avoid
checking in wherever possible though. And even then, sometimes I don’t have
any better ideas other than compile and link before running the test
