# `compiler-builtins` and `libm`

This repository contains two main crates:

* `compiler-builtins`: symbols that the compiler expects to be available at
  link time
* `libm`: a Rust implementation of C math libraries, used to provide
  implementations in `core`.

More details are at [compiler-builtins/README.md](compiler-builtins/README.md)
and [libm/README.md](libm/README.md).
