Ruby-LLVM is a Ruby language binding to the LLVM compiler infrastructure library. LLVM allows users to create just-in-time (JIT) compilers, ahead-of-time (AOT) compilers for multiple architectures, code analyzers and more. LLVM bindings can also be used to speed up Ruby code by compiling and loading computationally intensive algorithms on the fly.

This library currently binds to LLVM-18 (specifically llvm-c 18.

The first two digits of ruby-llvm's version number refer to the required major and minor version of LLVM. The third digit refers to the ruby-llvm release itself. Because LLVM's api changes often, this coupling between LLVM and ruby-llvm versions is useful.
