This might not map to LLVM, but it might be worth looking into. > - logging can be enabled/disabled at runtime This actually should be doable in LLVM. Since the LLVM DEBUG macro controls the -debug=... flag, I can't immediately see a reason why that wouldn't work for runtime toggling. > - logs can be redirected to various destinations The LLVM logging uses streams, so I don't think this is really different.
