[Bug c++/15036] [3.4 regression] Performance and code size regression compared to 3.3

[rth at gcc dot gnu dot org]

The code generated by gcc 4.0 is significantly improved:

.L2:
        fldl    -8(%ebx,%ecx,8)
        incl    %ecx
        fld     %st(0)
        fmull   (%edx)
        fxch    %st(1)
        fmull   8(%edx)
        fxch    %st(1)
        addl    $16, %edx
        fstpl   (%eax)
        fstpl   8(%eax)
        addl    $16, %eax
        cmpl    $1001, %ecx
        jne     .L2

I have no plans to address this for the 3.4 branch.
