Apart from the Dhrystone Cosmic issue I didn't see any. I was surprised
by the non-standard bool of Raisonance, since casts to bool behave
differently than the standard. It might be a bug or intent, I didn't
find any documentation on it.
I didn't consider it feasible with limited time and resources to run a
big test suite through the compilers to get a comparison on code
correctness. We know there are some in SDCC (since it has a public bug
tracker), but I have no reason to assume that the other compilers are
any better or worse; they just don't publish the information.
