 3.  **Microarchitecture detection.** On x86 some features are not always
     implemented efficiently in hardware (e.g. AVX on Sandybridge). Exposing the
     microarchitecture allows the client to reject particular microarchitectures.
+4.  All flavors of Mips are supported, little and big endian as well as 32/64
+    bits.

+## Android NDK's drop in replacement
+
+[cpu_features](https://github.com/google/cpu_features) is now officially
+supporting Android and offers a drop in replacement of for the NDK's [cpu-features.h](https://android.googlesource.com/platform/ndk/+/master/sources/android/cpufeatures/cpu-features.h)
+, see [ndk_compat](ndk_compat) folder for details.
