[Bug rtl-optimization/31704] x86_64 poor floating point register allocation across function call

[hubicka at gcc dot gnu dot org]

------- Comment #1 from hubicka at gcc dot gnu dot org  2008-02-07 16:36 -------
This is fixed by the call frequency patch on mainline.
.L2:
        cvtsi2ss        (%ebx,%eax,4), %xmm0
        addl    $1, %eax
        cmpl    $1000, %eax
        mulss   %xmm2, %xmm0
        addss   %xmm0, %xmm1
        jne     .L2

(on i386, but x86-64 behaves same way)
