Only for SIMD-optimized code. For remaining cases, you can help the compiler so it can generate very fast code (with current OoOE CPUs, the generated code may be suboptimal, but as fast as hand-tuned assembly because of the abundance of ALUs and load/store units in the CPU; also, current compilers are better than back in 1996).
