* Merging the previous ARM Neon branch Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Testing each SIMD variants using a small code snippet and first pass on unifying the way related cmake variables Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Removing the usage of USE_SSE in favor of the new OCIO_USE_SSE2 as they serve the same purpose Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Using try_compile instead of check_cxx_source_compiles as it was given false positive. Stubbing cpuinfo for Apple ARM plateform. Handling Apple M1 correctly and adding support for SSE2NEON. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Comments clean up and refactor some comments and documentations Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Added something in the documentation for Rosetta and small change in cmake Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Fixing the build under Rosetta and fixing issue in the MacOS CI. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Using try_compile for CheckSupportSSEUsingSSE2NEON to standardize the code and fixed CheckSupport compiler flags. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * use emmintrin.h for only sse2 features Signed-off-by: Mark Reid <mindmark@gmail.com> Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Allow F16C to be completely turned off Signed-off-by: Mark Reid <mindmark@gmail.com> Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Seperate SIMD test code from code that adds unit tests. This isolates the compulation units and avoids executing illegal hardware instructions Signed-off-by: Mark Reid <mindmark@gmail.com> Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * remove uneeded checks Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * use software implementations of f16c intrinsics for SSE2 Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Added preprocessor checks for ARM as it is needed for universal build on APPLE platform Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Adding missing checks for "not arm64" Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Ease the future maintainability a the new OCIO_USE_xyz be moving the logic into CPUInfoConfig.h.in as well as fixing issue on ARM when building with OCIO_USE_SSE2NEON=OFF. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Fixing some spacing, documentations and making some cmake conditions clearer. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Adding a build in ci_workflow for macos USE_OCIO_SSE2NEON=OFF Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * typo Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Changing back all the macOS (except one) builds to x86_64 only as it takes double the time to do the universal build. OCIO no longuer build a universal binary by default Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Update the CMakeLists.txt logic to accomodate all scenario and fixing documentations. Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> * Update documentation and remove ocio_use_sse2neon from the CI matrix Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> --------- Signed-off-by: Cédrik Fuoco <cedrik.fuoco@autodesk.com> Signed-off-by: Mark Reid <mindmark@gmail.com> Signed-off-by: Cédrik Fuoco <105517825+cedrik-fuoco-adsk@users.noreply.github.com> Co-authored-by: Mark Reid <mindmark@gmail.com> Co-authored-by: Doug Walker <doug.walker@autodesk.com>
