Help text

Inlines C helpers into Rust code using Link Time Optimization.

If this option is enabled, C helper functions declared in rust/helpers/ are inlined into Rust code, which is helpful for performance of Rust code. This requires a matching LLVM version for Clang and rustc.

If you are sure that you're using Clang and rustc with matching LLVM versions, say Y. Otherwise say N.
