That's interesting; I don't find them in the gcc-20030224 (3.3) snapshot.  In 
fact, I just checked this week, and that snapshot was not employing fnma 
instructions in my test code, so I applied this patch again.  The patterns 
which came in ia64.md require a sign change, to match the more common source 
code pattern, so it seems that a pattern with the sign change already applied 
is needed.
I don't find my patterns in the gcc-3.2.2 either, so I just tried applying 
the patch (on my ia32 laptop here at home), and it appears to take 
successfully.
My co-workers have not found a way to access CVS from our ia64 machines at 
the office, so I have always dealt with snapshots.
Thanks for looking at this. Not exactly a bug, it's a missing optimization.
