From the project
Renesas RX Microcontroller, C++ framework, Library, Sample
This is a program by Renesas RX microcontroller and its compiler rx-elf-gcc, g++. I am currently using Renesas GNU-RX gcc 8.3.0 as my main development tool. GNU-RX supports RXv3 and DFPU, and has excellent optimization.
Currently, a dedicated writing program has been implemented that has been tested on Windows, OS-X, and Linux. Development is now possible in multiple environments.
