In an ideal world yes, but the reality is that many people still use MSBuild, and in that world /MP presumably helps quite a bit. And given that many people already depend on this functionality of cl, it’s a potential showstopper for migrating if we don’t support it. That said, if the benefit isn’t significant that’s a stronger argument for not supporting it imo On Tue, Sep 18, 2018 at 12:45 AM Hans Wennborg via Phabricator < revi...@reviews.llvm.org> wrote:
