Rust language revs up compiler speed

With the release of Rust 1.13, developers have improved compiler performance and security for the programming language. An issue remains, however, with code generation for ARM processors.
For better compiler performance, Rust 1.13 uses optimization to cache normalized projections during translation. With the generation of the LLVM IR (intermediate representation), the compiler no longer has to recompute concrete instances of associated types each time; instead, it reuses previously computed val
