Hi all, Could a gatekeeper review the attached patch for bug #880?
This is caused by new rev3753, in follwoing code "TCON_R10" is only
defined at x8664, so this will break other targets build.
Modified: trunk/osprey/be/opt/opt_vn_expr.cxx

The fix is to make a new fun "Targ_Is_Neg_Zero" for each target to
determine whether the const is -0.0, just like "Targ_Is_Zero".
Thanks
