I hope you mean the actual size, not holding that value and larger.

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.
