Clang people, are there any secret tips on how to make it Compile Faster? GitHub kicks me out after 6 hours, I need to shave some time off my build 😅

I was going to suggest disabling LLVM assertions but then I found chromium.googlesource.com/chromium/src.g and realized they already did it themselves. They simply appear to have left the directory name as Release+Asserts even when assertions are disabled. It's worth double checking anyway.
They also already build Clang with PGO, ThinLTO and with hardening features like SSP disabled for performance. It could be built with LTO instead of ThinLTO to get better performance but I doubt it will help substantially. Could also set -march to a more recent CPU revision.

I haven’t gotten far enough in this process to build my own clang... but it will have to be done eventually
