The result of -dr for fixunsxfdi() for 4.2.4 is 648 lines. Only 80 are produced
by 4.3.5. It appears to die on the left shift.

If I understand correctly (disclosure - I might as well be trying to read
Klingon), both of these failures involve 64-bit.

This is also busted in all of 4.3 (0, 1, 2, 3, & 4) and 4.5.1.

Would a diff of the 4.2.4 and 4.3.0 m68k.md file be a useful attachment?

I'll do the 'svn thing'. But I am not an experienced svn user so it may take
some time.

Then again I suppose it could be in here:
(define_insn "extendsidi2"
- [(set (match_operand:DI 0 "nonimmediate_operand" "=d&

If someone wants to post svn commands to see the difference between the m68k.md

Thanks!!!
This worked. I never thought to try a Linux build. Live and learn.
I guess it is a good thing I'm not a gamblin' man.
