Check for the constraints and the conditions on the various insns that
have call anywhere in them, between top of tree and your 2.95.2 tree.

Look for this type of change:

     [(set (match_operand:SF 0 "gpc_reg_operand" "=f")
         (if_then_else:SF (match_operand 1 "comparison_operator" "")
!                         (match_operand:SF 2 "gpc_reg_operand" "f")

If you find something like that, then that might be what you need.  If
that isn't it, then I don't know quite what the problem is.

Yes, we do.  See my diffs for changes to dejagnu.  If you don't have
them, I'd be happy to email them to you.  They are large (3M), make
sure you can handle slightly larger email first.
