This is a shortcut for the needs descriptor 00000077:03515104_00000000_00000000. It requires blending a single 32-bit colour value into a 16-bit framebuffer. It's used when fading out the screen, eg. when a modal requester pops-up. The PF JIT produces code for this using 24 instructions/pixel. The NEON implementation requires 2.1 instructions/pixel. Performance hasn't been benchmarked, but the improvement is quite visible. This code has only been tested by inspection of the fading effect described above, when press+holding a finger on the home screen to pop up the Shortcuts/Widgets/Folders/Wallpaper requester. Along with the NEON version, a fallback v5TE implementation is also provided. This ARM version of col32cb16blend is not fully optimised, but is a reasonable implementation, and better than the version produced by the JIT. It is here as a fallback, if NEON is not available.
