The reason we build this file with -msse4.1 explicitly is because distributions build things for the lowest common denominator but we still want this code to be enabled (via a runtime check for SSE 4.1). If we do this, distributions building with typical CFLAGS won't get this optimization. That's not what we want. What's the problem with the current solution -- that the Android build system doesn't let you build this file with -msse4.1? _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
