Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/26440 As we are optimizing build size for Android/iOS, it starts diverging from default build on several build options, e.g.: - USE_STATIC_DISPATCH=ON; - disable autograd; - disable protobuf; - no caffe2 ops; - no torch/csrc/api; ... Create this build_mobile.sh script to 'simulate' mobile build mode with host toolchain so that people who don't work on mobile regularly can debug Android/iOS CI error more easily. It might also be used to build libtorch on devices like raspberry pi natively. Test Plan: - run scripts/build_mobile.sh -DBUILD_BINARY=ON - run build_mobile/bin/speed_benchmark_torch on host machine Differential Revision: D17466580 Pulled By: ljk53 fbshipit-source-id: 7abb6b50335af5b71e58fb6d6f9c38eb74bd5781
