elpm for mcu avr3

I'm using the latest binutils from CVS.

gcc knows that elmp is valid for avr31 and calls "as" with -mmcu=avr3, making
as reject it. Looks awfully like PR #35073 with another opcode.

What 4.4 snapshot did you use to build?

I'm getting something very similar, but it's for avr5, not avr3:

Same bug for me.  I've compiled gcc using

../configure --target=avr --program-prefix="avr-" --enable-languages=c

No error observed in gcc-4.4.0,libgcc.S compiles fine for -mmcu=avr31 with the
same command line as reported in the bug

Seems to be fixed now. Closing as WONTFIX.
