armv7 neon

NEON intrinsics provides a C function call interface to NEON operations, and the compiler will automatically generate relevant NEON instructions allowing you to program once and run on either an Armv7-A or Armv8-A platform.

Almost all ARMv7-based ("32-bit") Android devices support Neon, including all devices that shipped with API level 21 or later. The NDK enables Neon by default for both. If you target very old devices, you can filter out incompatible devices on the Google Play Console.

This guide introduces Arm Neon technology, the Advanced SIMD (Single Instruction Multiple Data) architecture extension for implementation of the Armv8-A or Armv8-R architecture profiles. Neon technology provides a dedicated extension to the Instruction Set Architecture, providing

It is supposed to compute sines and cosines really really fast on the NEON vector FPU. I know it compiles fine, but without adequate hardware I can't test it. If you could just compute a few sines and cosines and compare the results with those of sinf() and cosf() it would really help.
