The version reported is version 9, but for normal clang, version 7 is sufficient to AVX512. When a version of XCode does support AVX512, the version check can be updated to allow AVX512 for newer versions of XCode. with XCode 9.2 the following macro is set. __APPLE_CC__ 6000 Bug: libyuv:789 Test: gn gen out/Release "--args=is_debug=false target_os=\"ios\" ios_enable_code_signing=false target_cpu=\"x86\" use_xcode_clang=true" Change-Id: I5a9a0b4a2760c7d09a4bcb464b3668979113b07e Reviewed-on: https://chromium-review.googlesource.com/991595 Reviewed-by: richard winterton <rrwinterton@gmail.com> |

libyuv is an open source project that includes YUV scaling and conversion functionality.
- Scale YUV to prepare content for compression, with point, bilinear or box filter.
- Convert to YUV from webcam formats for compression.
- Convert to RGB formats for rendering/effects.
- Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
- Optimized for SSSE3/AVX2 on x86/x64.
- Optimized for Neon on Arm.
- Optimized for MSA on Mips.
