[Bug middle-end/27567] [4.0/4.1/4.2 Regression] __builtin_memcpy generates redundant stores/moves.

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-08-27 19:00 -------
For PPC, we get:
        stw 3,-16(1)
        stw 3,48(1)
        nop
        nop
        lfs 1,-16(1)
        blr

Notice the extra store, that does not need to be there.
