Ok: I'm happy with a skipping patch until I find time to investigate fallout (and if it'd make sense) changing MAX_FIXED_MODE_SIZE for CRIS. The docs are a bit misleading, DImode works fine, for instance. And of course, it would be right for remaining targets anyway. If there are more tests like this, we can consider an effective-target. I'll test and commit. Thanks.
