Hi @dragoudin,

Thanks for proposing this feature. Besides GCC IAR will be an interesting option.
Currently we do not have ressources nor a IAR licence to test with.

If you do please feel free to create a PR.

General documentation and how to add new compiler support (section Adding compiler support) can be found here: https://github.com/bmwcarit/Emma/blob/master/doc/dev-guide.md

Best regards,

Marcel.
