Double double assignment in optimized Cmm on SPARC

Hello, while reading ffi003 asm/opt-cmm for fixing this on SPARC I've noticed this code, this is optimized Cmm dump:

    112       c1or:
    113           _s1nw::F64 = F64[_s1nv::P32 + 3];
    114           _c1oj::I32 = sin;
    115           _c1ok::F64 = _s1nw::F64;

this assignment to _s1nw::F64 looks useless as we may assign directly to _c1ok::F64, may we not? Both optimized and non-optimized Cmms attached.
