Reason for revert: Gotta fix Test-Ubuntu-GCC-GCE-CPU-AVX2-x86_64-Release-SKNX_NO_SIMD Original issue's description: > SkHalfToFloat_01 / SkFloatToHalf_01 > > These are basically inlined, 4-at-a-time versions of our existing functions, > but cut down to avoid any work that's only necessary outside [0,1]. > > Both f16 and f32 denorms should work fine modulo the usual ARMv7 NEON denorm==zero caveat. > > In exchange for a little speed, f32->f16 does not round properly. > Instead it truncates, so it's never off by more than 1 bit. > > Support for finite values >1 or <0 is straightforward to add back. > >1 might already work as-is. > > Getting close to _u16 performance: > micros bench > 261.13 xferu64_bw_1_opaque_u16 > 1833.51 xferu64_bw_1_alpha_u16 > 2762.32 ? xferu64_aa_1_opaque_u16 > 3334.29 xferu64_aa_1_alpha_u16 > 249.78 xferu64_bw_1_opaque_f16 > 3383.18 xferu64_bw_1_alpha_f16 > 4214.72 xferu64_aa_1_opaque_f16 > 4701.19 xferu64_aa_1_alpha_f16 > > > BUG=skia: > GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1685133005 > > Committed: https://skia.googlesource.com/skia/+/9ea11a4235b3e3521cc8bf914a27c2d0dc062db9 TBR=jvanverth@google.com,reed@google.com,mtklein@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
