Does rewriting memcpy/memcmp/... with SIMD instructions make sense?
Does rewriting memcpy/memcmp/... with SIMD instructions make sense in a large scale software? If so, why doesn't GCC generate SIMD instructions for these library functions by default? Also, are t...

these functions are much faster with SSE instructions. It would be nice if your runtime library/compiler instrinsics would include optimized versions, but that doesn't seem to be pervasive.
