Hi, When RTH removed the expanding of some complex in fold, in the process he removed the constant folding of complex comparisions. This patch adds back the folding of complex comparisions for constants only and not the splitting of comparision for normal complex comparisions.

OK? Bootstrapped and tested on i686-linux-gnu with no regressions.

Thanks, Andrew Pinski

    * fold-const.c (fold_comparison): Add back the
    folding of constant complex comparisions.


    * gcc.c-torture/compile/pr30433.c: New testcase to check
    that complex constants comparisions are foldded.
