arm - Improve code with NEON on iOS - use VCEQ then VBIT -



arm - Improve code with NEON on iOS - use VCEQ then VBIT -

i writing histogram function looks @ vector info , puts elements in predefined "histogram" buckets based on range closest to.

i can using if status trying improve using neon because these image buffers.

one way vceq vbit sadly plenty not find vbit in header of neon. alternatively figured take vceq results , exclusive , vector of 1s , utilize vbif :-) vbif not there either!

any thoughts here? thanks

vbit, vbif, , vbsl same operation permutation of sources; can utilize vbsl* intrinsics of 3 operations.
