Closing bug and clearing flags on attachment 449737. 1833743 8 webkit-bug-importer 2022-01-25 09:37:37 -0800 <rdar://problem/88028497> 1833852 9 sabouhallawa 2022-01-25 14:06:46 -0800 I do not think the approach of this patch is correct. I am not very familiar with the code under #if HAVE(ARM_NEON_INTRINSICS) #if CPU(ARM_NEON) && CPU(ARM_TRADITIONAL) && COMPILER(GCC_COMPATIBLE) But my understanding is this code is an optimization for some arm7 platform. But since we do not have a bot for it, I even thought about removing it altogether. See bug 233500. This patch directs the code to the software applier which may not be suitable for this "unknown" platform. If you have a way to compile this code for this platform, I would suggest the following: 1. Add new class FEBlendNeonApplier under Source/WebCore/platform/graphics/cpu/arm/filters/ which should be similar to FEBlendSoftwareApplier. 2. Move the code in the deleted function FEBlend::platformApplySoftware() to FEBlendNeonApplier::apply(). 3. Make this change std::unique_ptr<FilterEffectApplier> FEBlend::createSoftwareApplier() const { #if HAVE(ARM_NEON_INTRINSICS) return FilterEffectApplier::create<FEBlendNeonApplier>(*this); #else return FilterEffectApplier::create<FEBlendSoftwareApplier>(*this); #endif } 449592 2022-01-20 09:56:03 -0800 2022-01-21 13:29:52 -0800 patch bug-235410-20220120185601.patch text/plain 5946 psaavedra
