[PATCH] Re: Fix problem with constant modulus

[Richard Kenner]

    I guess the proper fix is to revert the expand_mult_highpart_adjust
    change, and do the adjustment instead at its call sites in 
    expand_mult_highpart_optab; the following patch implements this.

    Bootstrapped/regtested on s390-ibm-linux and s390x-ibm-linux;
    fixes 5 ACATS test cases on s390.
    
    OK?

Yes, thanks.
