[Bug rtl-optimization/7061] Access of bytes in struct parameters

[pluto at agmk dot net]

------- Comment #6 from pluto at agmk dot net  2006-02-08 21:10 -------
one more testcase from x86-64 / gcc-4.1:

float re(float _Complex a) { return __real__ a; }

is compiled to:

re: movq    %xmm0, -8(%rsp)
    movss   -8(%rsp), %xmm0
    ret

but can be optimized to `movss %xmm0, %xmm0`.
