# compiler-rt-builtins The LLVM compiler-rt builtins source, conveniently packaged as a Rust crate. ```toml [dependencies] compiler-rt-builtins = "0.1" ``` In your `build.rs`: ```rust println!("cargo:rustc-link-lib=compiler-rt-builtins"); ``` Created because when compiling C code to `wasm32-unknown-unknown`, some builtins are missing from Rust's `compiler_builtins`. Might have other uses too, who knows?
