Introduce a new module, `naga:🔙:continue_forward`, containing
shared code for rendering Naga `Continue` statements as backend
`break` statements and assignments to introduced `bool` locals.
See the module's documentation for details.
- [hlsl-out] Transform degenerate single body switches into `do-while`
loops. Properly render `Continue` statements enclosed by
`Switch` statements enclosed by `Loop` statements.
- [glsl-out] Transform degenerate single body switches into `do-while`
loops.
Improve `naga xtask validate spv` error message.
Fixes#4485.
Fixes#4514.
* Expose gpu allocation configuration options
This commit adds hints to control memory allocations strategies to the configuration options. These hints allow for automatic profiles such as optimizing for performance (the default, makes sense for a game), optimizing for memory usage (typically more useful for a web browser or UI library) and specifying settings manually.
The details of gpu allocation are still in flux. The goal is to switch vulkan and metal to gpu_allocator which is currently used with d3d12. gpu_allocator will also likely receive more configuration options, in particular the ability to start with smaller memory block sizes and progressively grow the block size. So the manual settings already provision for this upcoming option. Another approach could be to wait and add the manual option after the dust settles.
The reason for providing presets and defining values in the backends is that I am convinced that optimal fonigurations should take hardware capabilities into consideration. It's a deep rabbithole, though, so that will be an exercise for later.

* Allow unconsumed inputs in fragment shaders by removing them from vertex
outputs when generating HLSL.
Fixes https://github.com/gfx-rs/wgpu/issues/3748
* Add naga:🔙:hlsl::FragmentEntryPoint for providing information
about the fragment entry point when generating vertex entry points via
naga:🔙:hlsl::Writer::write. Vertex outputs not consumed by the
fragment entry point are omitted in the final output struct.
* Add naga snapshot test for this new feature,
* Remove Features::SHADER_UNUSED_VERTEX_OUTPUT,
StageError::InputNotConsumed, and associated validation logic.
* Make wgpu dx12 backend pass fragment shader info when generating
vertex HLSL.
* Add wgpu regression test for allowing unconsumed inputs.
* Address review
* Add note that nesting structs for the inter-stage interface can't
happen.
* Remove new TODO notes (some addressed and some transferred to an issue
https://github.com/gfx-rs/wgpu/issues/5577)
* Changed issue that regression test refers to 3748 -> 5553
* Add debug_assert that binding.is_some() in hlsl writer
* Fix typos caught in CI
Also, fix compiling snapshot test when hlsl-out feature is not enabled.
* share timestamp write struct
* Make name of set_push_constants methods consistently plural
* remove lifetime bounds of resources passed into render pass
* first render pass resource ownership test
* introduce dynrenderpass & immediately create ArcCommands and take ownership of resources passed on pass creation
* Use of dynrenderpass in deno
* Separate active occlusion & pipeline statitics query
* resolve render/compute command is now behind `replay` feature
* add vertex & index buffer to ownership test
* test for pipeline statistics query
* add occlusion query set to pass resource test
* add tests for resource ownership of render pass query timestamps
* RenderPass can now be made 'static just like ComputePass. Add respective test
* Extend encoder_operations_fail_while_pass_alive test to also check encoder locking errors with render passes
* improve changelog entry on lifetime bounds
To support atomic instructions in the SPIR-V front end, observe which
global variables the input accesses using atomic instructions, and
adjust their types from ordinary scalars to atomic values.
See comments in `naga::front::atomic_upgrade`.
* ensure that `wgpu::Error` is `Sync`
This makes it possible to wrap the error in `anyhow::Error` and
`eyre::Report`, which require the inner error to be `Sync`.
* update changelog
Add the following flags to `wgpu_types::Features`:
- `SHADER_INT64_ATOMIC_ALL_OPS` enables all atomic operations on `atomic<i64>` and
`atomic<u64>` values.
- `SHADER_INT64_ATOMIC_MIN_MAX` is a subset of the above, enabling only
`AtomicFunction::Min` and `AtomicFunction::Max` operations on `atomic<i64>` and
`atomic<u64>` values in the `Storage` address space. These are the only 64-bit
atomic operations available on Metal as of 3.1.
Add corresponding flags to `naga::valid::Capabilities`. These are supported by the
WGSL front end, and all Naga backends.
Platform support:
- On Direct3d 12, in `D3D12_FEATURE_DATA_D3D12_OPTIONS9`, if
`AtomicInt64OnTypedResourceSupported` and `AtomicInt64OnGroupSharedSupported` are
both available, then both wgpu features described above are available.
- On Metal, `SHADER_INT64_ATOMIC_MIN_MAX` is available on Apple9 hardware, and on
hardware that advertises both Apple8 and Mac2 support. This also requires Metal
Shading Language 2.4 or later. Metal does not yet support the more general
`SHADER_INT64_ATOMIC_ALL_OPS`.
- On Vulkan, if the `VK_KHR_shader_atomic_int64` extension is available with both the
`shader_buffer_int64_atomics` and `shader_shared_int64_atomics` features, then both
wgpu features described above are available.
* add new tests for checking on query set lifetime
* Fix ownership management of query sets on compute passes for write_timestamp, timestamp_writes (on desc) and pipeline statistic queries
* changelog entry
* Reintroduce computepass->encoder lifetime constraint and make it opt-out via `wgpu::ComputePass::make_static`
* improve comments based on review feedback
* use the same lifetime name for all usages of `ComputePass<'encoder>`
* comment improvement that I missed earlier
* more review based comment improvements
* use suggested zero-overhead lifetime removal
* rename make_static to forge_lifetime
* missed comma
* 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
* Add support for pipeline-overridable constants in WebGPU
* Add utility function for setting constants map
* Panic on failure to set constants map
