Subject: Ooops, don't forget to clear this.  The real inner loop is now:
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=27e5142309946ca12c633b265673af0c24684427;p=oota-llvm.git

Ooops, don't forget to clear this.  The real inner loop is now:

.LBB_foo_3:     ; no_exit.1
        lfd f2, 0(r9)
        lfd f3, 8(r9)
        fmul f4, f1, f2
        fmadd f4, f0, f3, f4
        stfd f4, 8(r9)
        fmul f3, f1, f3
        fmsub f2, f0, f2, f3
        stfd f2, 0(r9)
        addi r9, r9, 16
        addi r8, r8, 1
        cmpw cr0, r8, r4
        ble .LBB_foo_3  ; no_exit.1
