This proves a flag in msl::PipelineOptions that attempts to write all
Metal vertex entry points to use a vertex pulling technique. It does
this by:
1) Forcing the _buffer_sizes structure to be generated for all vertex
entry points. The structure has additional buffer_size members that
contain the byte sizes of the vertex buffers.
2) Adding new args to vertex entry points for the vertex id and/or
the instance id and for the bound buffers. If there is an existing
@builtin(vertex_index) or @builtin(instance_index) param, then no
duplicate arg is created.
3) Adding code at the beginning of the function for vertex entry points
to compare the vertex id or instance id against the lengths of all the
bound buffers, and force an early-exit if the bounds are violated.
4) Extracting the raw bytes from the vertex buffer(s) and unpacking
those bytes into the bound attributes with the expected types.
5) Replacing the varyings input and instead using the unpacked
attributes to fill any structs-as-args that are rebuilt in the entry
point.
A new naga test is added which exercises this flag and demonstrates the
effect of the transform. The msl generated by this test passes
validation.
Eventually this transformation will be the default, always-on behavior
for Metal pipelines, though the flag may remain so that naga
translation tests can be run with and without the tranformation.
* lift encoder->computepass lifetime constraint and add now failing test
* compute passes now take an arc to their parent command encoder, thus removing compile time dependency to it
* Command encoder goes now into locked state while compute pass is open
* changelog entry
* share most of the code between get_encoder and lock_encoder
* rename `command_encoder_run_*_pass` to `*_pass_end` and make it a method of compute/render pass instead of encoder
* executing a compute pass consumes it now such that it can't be executed again
* use handle_error instead of handle_error_nolabel for wgpu compute pass
* use handle_error instead of handle_error_nolabel for render_pass_end
* changelog addition
* feat: `compute_pass_set_push_constant`: move panics to error variants

* basic test setup
* remove lifetime and drop resources on test - test fails now just as expected
* compute pass recording is now hub dependent (needs gfx_select)
* compute pass recording now bumps reference count of uses resources directly on recording
TODO:
* bind groups don't work because the Binder gets an id only
* wgpu level error handling is missing
* simplify compute pass state flush, compute pass execution no longer needs to lock bind_group storage
* wgpu sided error handling
* make ComputePass hal dependent, removing command cast hack. Introduce DynComputePass on wgpu side
* remove stray repr(C)
* changelog entry
* fix deno issues -> move DynComputePass into wgc
* split out resources setup from test
* Fix cts_runner command invocation in readme
* Remove assertDeviceMatch from deno_webgpu in createBindGroup
This should be done as verification in wgpu-core.
* Add device mismatched check to create_buffer_binding
* Extract common logic to create_sampler_binding
* Move common logic to create_texture_binding and add device mismatch check
* Add serde, serialize, deserialize features to wgpu and wgpu-core
Remove trace, replay features from wgpu-types
* Do not use trace, replay in wgpu-types anymore
* Make use of deserialize, serialize features in wgpu-core
* Make use of serialize, deserialize features in wgpu
* Run cargo fmt
* Use serde(default) for deserialize only
* Fix serial-pass feature
* Add a comment for new features
* Add CHANGELOG entry
* Run cargo fmt
* serial-pass also needs serde features for Id<T>
* Add feature documentation to lib.rs docs
* wgpu-types implicit serde feature
* wgpu-core explicit serde feature
* wgpu explicit serde feature
* Update CHANGELOG.md
* Fix compilation with default features
* Address review comments
* Convert Tests to Use Async Poll
* Update examples/src/repeated_compute/mod.rs

* Add `BGRA8UNORM_STORAGE` extension
* Leave a comment in the backends that don't support bgra8unorm-storage
* Pass the appropriate storage format to naga
* Check for bgra8unorm storage support in the vulkan backend
* Add a test

* wgpu-core: Only produce StageError::InputNotConsumed on DX11/DX12
This error only exists due to an issue with naga's HLSL support:
https://github.com/gfx-rs/naga/issues/1945
The WGPU spec itself allows vertex shader outputs that are
not consumed by the fragment shader.
Until the issue is fixed, we can allow unconsumed outputs on
all platforms other than DX11/DX12.
* Add Features::SHADER_UNUSED_VERTEX_OUTPUT to allow disabling check
* Pick an unused feature id
