At least on my mac it passed. With that check.
I double checked, and this is what I see:
./bin/clang -### -c -target x86_64 -gsplit-dwarf -g /Users/ayermolo/local/llvm-project/clang/test/Driver/split-debug.c
"-dwarf-version=5" "-debugger-tuning=gdb" "-ggnu-pubnames"
./bin/clang -### -c -gsplit-dwarf -g /Users/ayermolo/local/llvm-project/clang/test/Driver/split-debug.c
"-dwarf-version=4" "-debugger-tuning=lldb"
