Remove `PartialEq` derivations from various Naga IR types on which
equality doesn't really make sense. In some cases, derive only in
`cfg(test)` builds, so tests can check for expected output.
In the GLSL front end, use `append` to add new constants, not
`fetch_or_append`, since the latter requires `PartialEq` yet GLSL
doesn't permit duplicate declarations anyway.
* 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
A recent change by rustc, now in 1.79-stable, makes empty str constants
point to the same location: 0x01. This is an optimization of sorts, not
stable behavior. Code must not rely on constants having stable addresses
nor should it pass &"" to APIs expecting CStrs or NULL addresses.
D3DCompile will segfault if you give it such a pointer, or worse:
read random garbage addresses!
Pass the NULL pointer to D3DCompile if wgpu lacks a decent CString.

Skip
`wgpu_test::compute_pass_ownership::compute_pass_resource_ownership`
on the GL backend on AMD Radeon Pro WX 3200, to avoid the kernel crash
described in #5800.
Drop the first field of `wgpu::SubmissionIndex`, as it is unused.
Adjust uses of the types' other field.
Delete the `wgpu::context::Context` trait's `SubmissionIndex`
associated type. Remove it from implementations.
Drop the first field of the `Context` trait's `queue_submit` method's
return value. Adjust implementations.
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
Since `BlockContext::resolve_pointer_type` never returns an error,
change its result type from a `Result` to a `&TypeInner`. Adjust
callers accordingly.
Remove calls (well, there's only one) to `resolve_pointer_type`
entirely when the caller does not need the value, since
`resolve_pointer_type` is now infallible and has no side effects.
Remove `valid::expression::ExpressionError::DoesntExist`. This error is reported
when expression validation encounters an invalid `Handle<Expression>`, but we
have already verified that the module is free of invalid handles in
`Validator::validate_module_handles`, so this condition should never arise.
Fix links in documentation for types defined using the `bitflags!` macro.
As described in [bitflags#407], for some reason, `cargo doc` doesn't
check for broken links in documentation for types or members defined
using `bitflags::bitflags!`.
