 As this is a front-end project, the compiler will gain full access to all of GCCs internal middle-end optimization passes which are distinct from LLVM. For example, users of this compiler can expect to use the familiar -O2 flags to tune GCC’s optimizer. Going forward, we will be happy to see more LLVM vs GCC graphs in respect to compilation speed, resulting code size and performance. 
 
-The project is still in an early phase with the goal to compile the offical rust test suite. There are no immediate plans for a borrow checker as this is not required to compile rust code and is the last pass in the RustC compiler. This can be handled as a sperate project when we get to that point.
