I actually had to build LLVM last week, so I feel your pain. I ran it on my Mac, thankfully, but I accidentally built in debug mode and ended up a 25 GB build folder. Turning on release mode and -Os brought it down to two or three gigabytes.

After installing Xcode and stuff, on my MacBook Pro, there is usually less than 10GB free space. I have to delete and purge up and down till ~14GB for sure every time Xcode gets updated.

If you’re looking to clean some space, I recommend checking out ~/Library/Developer/Xcode. Among other things, Xcode stores device symbols for every iOS device you’ve ever connected to your Mac here. You might be able to clean out a couple gigabytes.
