Trevor Gross 3fb16fbdbe macros: Always emit f16_enabled and f128_enabled attributes 
Once we start addinf `f16` and `f128` routines, we will need to have
this cfg for almost all uses of `for_each_function`. Rather than needing
to specify this each time, always emit `#[cfg(f16_enabled)]` or
`#[cfg(f128_enabled)]` for each function that uses `f16` or `f128`,
respectively.

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
