  "message": "Merging hal.device.switch feature branch.\n\nAdding a new `hal.device.switch` op that allows us to nicely generate backend/device-specific logic that can be transformed into efficient code for runtime. There\u0027s a lot of folders needed to help here, however this initial structure will let us begin work on #1168 as it exposes the ability to generate device-specific dispatch ops.\n\nFuture iteration will add more device matchers to allow more fine-grained codegen. For example, matchers that look for supported device-specific extensions, minimum allocation alignment, unified vs. discrete memory, maximum descriptor set count, etc can all be added in a generic way and efficiently lowered to runtime code.\n\nProgress towards heterogeneous execution will cause the `!hal.device` type to change to a `hal.device\u003cordinal\u003e` form, allowing better compile-time evaluation of the `hal.device.switch` blocks when placement happens. For now we still only have a single runtime-selected `hal.ex.shared_device` so this cannot happen.\n\nCloses https://github.com/google/iree/pull/1393\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/google/iree/pull/1393 from google:benvanik-hal-device-switch d0348ef32a6af9940d4f9243a1cce88921bd398e\nPiperOrigin-RevId: 306259903\n",
