  • 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.

 

Superior Optimization

By the enhanced optimization, this compiler generates more compact codes and easier optimization settings on GUI.

[Generation of compact codes]

A benchmark test confirms that code efficiency is improved by over 30% comparable current Renesas products.

 

[Complier Optimization]

  • Easy selection of optimization
    • Selection of Size or Speed priority
    • Selection of optimization level (-optimize=0 or 1 or 2 or max.)
  • Wide-ranging optimization when compiling
    • Function's inline-expansion between files
    • Symbol access optimization that use external symbol allocation information from optimization linker
  • Detailed setting of optimization
    • Loop expansions, instructions order, optimization range specification, register allocation etc.

 

[Liker Optimization]

  • Inter-module optimization
    • Remove unreferenced symbol, optimization for branch, Unifies same codes, Shortens the addressing mode
    • Detailed setting of optimization partially disabled

 

[Optimization of standard library]

  • Application of compiler optimization
    • A standard library is targeted on optimization and a compact code is generated with the entire program, too.

 

Porting Support

This RX compiler respects the customer's need for compatibility with their existing software resources. It supports compiler language specifications of existing products and facilitates program migration from existing Renesas mid-range products, such as M16C, R32C, H8S, and H8SX. Moreover, by superior optimization, existing objects transform themselves into RX objects that are more compact and efficient.

 

[Option settings that absorb language specifications]

OptionDescription
dbl_size = 4 | 8Specifies the precision of the double type and long double type. (either the 4-byte single-precision floating type or the 8-byte double-precision floating type.)
int_to_shortBefore compiling, the int type is replaced with the short type and the unsigned int type is replaced with the unsigned short type in the source file.
signed_char / unsigned_charSpecifies the sign of the char type with no sign specification.
signed_bitfield / unsigned_bitfieldSpecifies the sign of the bit-field type with no sign specification.
bit_order = left | right

Specifies the order of bit-field members.

 

[Checking of specific extended specifications]

OptionDescription
check = nc | ch38 |shc

Checks the specified options and source file parts which will affect the compatibility when this compiler uses a C/C++ source file that has been coded for the SuperH family C/C++ compiler, R8C and M16C family C/C++ compilers and H8, H8S and H8SX family C/C++ compilers.
When compiling source code for "C/C++ Compiler Package for H8SX, H8S, H8 Family", specify "ch38".
When compiling source code for "C/C++ Compiler Package for R8C and M16C Families", specify "nc". When compiling source code for "C/C++ Compiler
Package for SuperH Family", specify "shc".

 

[Ability to switch endian alignment]

OptionDescription
endian= big | little

Specifies the byte order of the data (little or big endian).
For migration from "C/C++ Compiler Package for H8SX, H8S, H8 Family", specify "big".
For migration from "C Compiler Package for R8C and M16C Families", specify "little".

Note

Underline shows the default value.

Notes

  1. The difference between the standard and professional editions, Refer to here for details.
  2. A license key is common for both distribution format "with" and "without" IDE. In other words, a license key can be applicable for any or both of CS+ and e² studio.
    e.g.: When buying C/C++ Compiler without IDE, it's possible to download CS+ from a web, install, register a bought license key and use.
  3. Further updating of the the C/C++ Compiler package for RX Family for High-performance Embedded Workshop is not planned. Note that we do not plan support for the RX100 series and the MCUs equipped with the RXv2 core (the RX64M group and the RX700 series). Click HERE for more information.
  4. High-performance Embedded Workshop
  5. We currently support only the following products with both floating and annual licenses.
    - C/C++ Compiler Package for RX Family (CC-RX) V2.03.00 or later
  6. The e² studio or CS+ must be installed separately.
  7. CS+ is not promoted in America and Europe. Please contact your regional marketing/sales team for information.
