[MPlayer-dev-eng] [PATCH]: af_resample SIMD optimization (MMX/SSE2/3DNOW!/SSE/SSE3)

[Zhou Zongyi]

Hi,

Even if s->w is 16-byte aligned, &x[xi] and &w[wi*L] is not. Thus aligned SSE instruction still crashes.

During the "UP" phase x is loaded outside the inner-loop, so multiplication from memory is not necesary.
