> What's the story with TFmode for FMA?

There have never been TFmode float operations implemented in hardware
ever for sparc, and I doubt we'll see it in the future.

And this applies also to the FMA instructions.

And especially since the presence of the FMA patterns is meant to be a
performance enhancement, I don't see much value to considering TFmode
cases.

Did you have something specific in mind?

No problem.
