Features
- ANSI-compliant
- Support C89, C99 of ANSI
Note: The variable length array type, complex type, and some standard library functions of the C99 standard are not supported.
- Support C89, C99 of ANSI
- Superior optimization
- The compiler applies our latest optimization techniques to generate code that has excellent performance in execution (up to a three-fold (Measured for programs held by Renesas) improvement in execution performance over code compiled by the CA78K0R compiler, our previous product)
- The compiler applies our latest optimization techniques to the generation of compact code (up to a 10-percent (Measured for programs held by Renesas) improvement over the CA78K0R).
- Easy optimization settings and many optimization features
- Linker-level optimization is now included in addition to optimization at the compiler level.
- Cooperated with RL78 MCU architecture
- Interrupt processing routines can be written in the C language (up to a six-fold (Measured for programs held by Renesas) improvement in interrupt response performance over code compiled by the CA78K0R compiler)
- Provides intrinsic functions
- An MISRA C rule checker supports the description of high-quality program [Professional edition only]
- Supports automatic checking of C source code based on the MISRA-C: 2004/2012 rules as compiler options
- About MISRA C, refer to here. [Learn More]
- Assistance in Porting Files to the CC-RL from the CA78K0R. [Learn More]
