Subject: [PATCH] [compiler-rt/llvm] Enable profile instrumentation for
SerenityOS
Treat SerenityOS the same as other *NIX platforms that behave close
enough to linux to use the pre-canned InstrProfiling implementation.
Curiously, enabling profiling for the SerenityOS target changes the ELF
OS ABI for userspace binaries to 3, or GNU/Linux.
