I'd certainly be concerned. Ports have (for better or worse) keyed on
BLKmode rather than looking at the underlying types. So if something
which was previously SImode or DImode is now BLKmode, there's a nonzero
chance we're going to change how it gets passed.
Well, we have been saying that calling conventions need to be keyed on types
rather than modes for more than a decade... I recall auditing and fixing the
SPARC back-end circa 2003, so how long are we going to use this argument?
I don't recall such a change in policy -- but that doesn't mean it
didn't happen :-)
If we already declared that ports should be looking at the underlying
types rather than the mode and it's been in place that long, then I
think any port that hasn't been audited/updated deserves its fate and we
shouldn't let them stand in the way of making progress on this issue.
