Ah. That was a useful link for a lot of context.
I tried to do a sparse-checkout with ‘set clang’ (as a start). But running cmake to prep the ninja build died on missing files. So, I guess the whack-a-directory process begins. I went down this rabbit hole a bit and kept having to add directories on the llvm side. I’m not sure if I’m going to try much more to disentangle these threads.
It seems like there’s enough interconnectedness that I won’t end up with a much smaller source tree even if I can get it to work. Unless I’m missing the right way to invoke cmake for what I’m trying to do (very possible).
Again, thanks to all for the help.
