Allow unconsumed inputs in fragment shaders

2

By removing them from vertex outputs when generating HLSL. * Add `naga::back::hlsl::FragmentEntryPoint` for providing information about the fragment entry point when generating vertex entry points via `naga::back::hlsl::Writer::write`. Vertex outputs not...

`parse_example_wgsl` test not actually checking examples?

4

https://github.com/gfx-rs/wgpu/blob/f735f57f89bef92896a5421a750f8bff7531fd81/naga/tests/example_wgsl.rs#L8-L18 This looks for `CARGO_MANIFEST_DIR/examples` but `CARGO_MANIFEST_DIR` is the package folder not the workspace folder. I put a panic in the `Err` arm and it causes the test to fail....

Detecting races when releasing Tree Borrows protectors?

4

IIUC in tree borrows protectors generate implicit reads when they are released. However, the data race detector doesn't seem to be aware of them. Does it make sense for these...

`raw_debug_message_callback` seems to be called after `Context` is dropped

8

Dropping `Context` will attempt to clear the debug callback via `gl.DebugMessageCallback(None, std::ptr::null());` since it drops the state that the callback refers to. But I was getting segfaults, so I added...

Right now it creates a mutable reference to the user data which requires exclusivity. But https://www.khronos.org/opengl/wiki/Debug_Output#Getting_messages notes: >The callback can be called synchronously or asynchronously. This is controlled by the...

Allow `panic = "abort"` for benchmarks when `harness = false`.

13

### Problem The `panic` setting is ignored for benchmarks since (by default) they link `libtest` which is compiled with `panic = "unwind"`. This would otherwise lead to confusing errors at...

Workaround shader compiler bugs with degenerate switch statements

11

**Connections** Fixes https://github.com/gfx-rs/wgpu/issues/4514 Fixes https://github.com/gfx-rs/wgpu/issues/4485 **Description** As discussed in https://github.com/gfx-rs/wgpu/issues/4485, FXC has a bug when handling switches with all cases leading to one body (it deletes the switch). It was...

I ran into a SPIRV validation issue in a test case I added in my PR https://github.com/gfx-rs/wgpu/pull/5654#issuecomment-2092368818. I've been able to reduce it down to: This input wgsl ```wgsl @compute...

FXC has a bug when compiling the shader shown in https://github.com/gpuweb/gpuweb/issues/4430 See https://issues.chromium.org/issues/42251176#comment5 which discusses the bug in 4430 and the likelihood of other switch/loop related bugs. I'm not sure...

Add a section in readme linking to other options

e.g. see https://github.com/ralith/hecs?tab=readme-ov-file#other-libraries IMO these entries can be really useful for discovering other parts of the ecosystem.
