![]() You might also want a mechanism that enables sharing common subroutines and utility functions without the need of compiling the same code twice or having it loaded in memory more than once. You might want a way to save the entire time cost of pipeline state compilation, from source, to AIR, to a GPU binary. Additionally under this model apps are unable to re-use any previously generated machine code subroutines across different pipeline state objects. This process is great, and has served us well of building pipeline objects early on to provide a hitch-free experience, this process can potentially result in long loading screens. To accelerate recompilation and recreation of pipelines we cache the Metal Function variants produced in this step for future pipeline creation. This process occurs for every pipeline state. this intermediate representation is further compiled on device to generate machine specific code needed for each particular GPU. In both cases, however when creating pipeline state objects. Building off-line avoids the runtime cost of compiling source code to AIR. This can be done off-line, in Xcode, or at runtime on the target device itself. ![]() Metal compiles this code into Apple's Intermediate Representation also known as AIR. And finally Ravi will present in detail the set of tools that you have in yourĪs you know the metal shading language is our programming language for shaders.I'm excited to share the new support for dynamic libraries in metal.This feature will allow you to link your compute shaders against utility libraries dynamically.Next I'm going to introduce Metal Binary Archives, a new way for you to take control over shader caching, and ship precompile GPU executables to your users. ![]() First up I'll provide an overview of Metal's current Shader compilation model.WWDC2020_Get to know Metal function pointers.WWDC2021_Discover compilation workflows in Metal.本节内容,来自 WWDC2020_Build GPU binaries with Metal
