In general, any C++ features supported by the prebuilt platform toolchain are allowed. 12*38e8c45fSAndroid Build Coastguard Worker 13*38e8c45fSAndroid Build Coastguard WorkerUse "clang-format -style=file" to format all C/C++ code, except code imported verbatim from elsewhere. Setting up git-clang-format in your environment is recommended. 14*38e8c45fSAndroid Build Coastguard Worker 15*38e8c45fSAndroid Build Coastguard Worker## Code Generation 16*38e8c45fSAndroid Build Coastguard Worker 17*38e8c45fSAndroid Build Coastguard WorkerWe generate several parts of the loader and tools directly from the Vulkan Registry (external/vulkan-headers/registry/vk.xml). Code generation must be done manually because the generator is not part of the platform toolchain (yet?). Files named `foo_gen.*` are generated by the code generator. 18*38e8c45fSAndroid Build Coastguard Worker 19*38e8c45fSAndroid Build Coastguard Worker### Run The Code Generator 20*38e8c45fSAndroid Build Coastguard Worker 21*38e8c45fSAndroid Build Coastguard WorkerInstall Python3 (if not already installed) and execute below: 22*38e8c45fSAndroid Build Coastguard Worker`$ ./scripts/code_generator.py` 23
