I'm pretty sure I had it miscompiled with -mcpu=ev56 too.

Ok.  I had no idea what the upper limit should be, and (probably wrongly) 
guessed it would vary depending on the kind of function evaluated.  Last time 
I asked on the list, I was told that the errors in math test on alpha were 
expected, and I (again, probably wrongly) assumed they were "normal" and could 
be dealt with by adjusting the expected results...

Did the fix get included in GCC CVS yet ?

Bleeding edge huh ? ;-)  You mean HJ released another binutils, or do you use 
the binutils CVS from sourceware ?
