Trevor Gross 2cbacf89af Fix a bug in abs_diff
These were taken from `compiler-builtins` but the implementation has a
bug near the integer limits. Fixed in `compiler-builtins` by using
`core`'s implementation at [1], this is the corresponding fix for
`libm`.

libm

A port of MUSL's libm to Rust.

Goals

The short term goal of this library is to enable math support (e.g. sin, atan2) for the wasm32-unknown-unknown target (cf. rust-lang/compiler-builtins). The longer term goal is to enable math support in the core crate.

Already usable

This crate is on crates.io and can be used today in stable #![no_std] programs.

The API documentation can be found here.

Benchmark

The benchmarks are located in crates/libm-bench and require a nightly Rust toolchain. To run all benchmarks:

cargo +nightly bench --all
