I see exceptionally high memory usage compiling flang (compared to other parts of LLVM) across clang, gcc, and msvc. Sure the problem is more extreme on some compilers than others, but even when building with clang I have to limit the threads on my machine or use a memory-optimized instance because flang (and only flang) cannot be built with normal ratios of cores to memory.

I do agree that maintenance is important. This may or may not be the solution but I think there is a real issue here.
