NB: This is untested, because rebuilding LLVM is a hassle on the machine I'm currently on (and MSVC may ignore it anyway). |
|
For me, linking LLVM in parallel (-j8 for my number of cores) consumes more than 8 GB of memory, while building it never consumes more than ~2 GB, so it would be very nice to be able to build quickly (in parallel) but not link in parallel. |

I have no idea what this "merge conflict" is about, I just rebased without conflicts?! Maybe that unwedges bors ¯\_(ツ)_/¯ |
