 The YJIT `ruby` binary can be built with either GCC or Clang. For development, we recommend enabling debug symbols so that assertions are enabled as this makes debugging easier. Enabling debug mode will also make it possible for you to disassemble code generated by YJIT. However, this causes a performance hit. For maximum performance, compile with GCC, without the `DRUBY_DEBUG` or `YJIT_STATS` build options. More detailed build instructions are provided in the [Ruby README](https://github.com/ruby/ruby#how-to-compile-and-install).
-To support disassembly of the generated code, `libcapstone` is also required (`brew install capstone` on MacOS, `sudo apt-get install -y libcapstone-dev` on Ubuntu/Debian).

+Typically configure will choose default C compiler. To specify the C compiler, use

 You can test that YJIT works correctly by running:
