I haven't found a way to control GCC's target selector at runtime (though in theory it could be possible), so switching between specific optimizations (SSE2 vs SSSE3) may prove difficult or require additional duplication of code. Bypassing the optimizations completely in an all-or-nothing way should be possible relatively easily, though.
