There are lots of ways for the platform dependent back end code to cause compiler ICE, and of course wrong-code generation issues.  If it’s in the FSF code as opposed to NetBSD local mods, it would be good to get those logged in the GCC bug tracker.  And of course development of fixes is likely to be valuable, especially for the more obscure targets that don’t get as much GCC maintainer energy.

I wonder how many issues the GCC test suite when run on one of those ports would turn up.
