Remember that there are cpus like imx51 to2 which have broken neon and this is shown in /proc/cpuinfo (no neon flag for them). So using own tests should also check what kernel has to say. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
