llvm dev - Dec 2018 - [llvm-pdbutil] : merge not working properly

When trying to merge 2 pdbs which have each their own DBI stream, I endup
with a pdb with an inconsistent number of stream and no DBI stream (or at
least not at fixed index 3, producing a corrupt error when dumping with -l).
Looking at the code, it seems that we don't merge other streams than TPI
and IPI streams, am I right ?
Is the "merge" feature completely implemented ?
Thanks

The merge feature was implemented primarily for testing but was never
really productionized, so your guess about what the underlying problem is
sounds correct to me. We could probably hide the subcommand so users don’t
accidentally use it, or if someone wants to properly implement the missing
features, that would be even better

Were you the man in charge of this feature ? If not, do you know who was in
charge (to see what could be the best way / what is missing to complete
this feature) ?
