CC-RH is equipped with the following special features.

The C language specifications conform to the C90 and C99 standards.

Advanced optimization is used, applying global program optimization as well as conventional optimization.

This yields smaller, faster code, and also reduces build times.

The program supports porting programs from the existing SuperH RISC engine C/C++ compiler.

In addition, the industry-standard DWARF2 and DWARF3 format is used for debugging information.

Static analysis and other functionality is provided via linking between CS+.
