libdawn will be one of the libraries produced but other libraries like
libdawn_native don't need to link against it. However they do need the
Dawn headers so we generate them separately.
This also makes all internal targets depend on the header generation and
have the include directories necessary for those headers.
Also has a small fix for setting compile flags only for C++ files.
This removes the following for both Buffer and Texture:
- The builder's SetInitialUsage
- The object's FreezeUsage and TransitionUsage methods
- The CommandBuffer Transition<Object>Usage methods
All samples and tests are simplified as a result. This also obsoletes
the UsageValidationTest which is removed.
Some validation was dependent on "current usage" and hasn't been
reintroduced for implicit transitions yet:
- Buffers can be used while mapped
- Swapchain textures can be used after they have been presented.
Validation for these will involve collecting all the resources used by a
command buffer and will be done in a follow-up patch.
* Use a descriptor for BindGroupLayout
* Fix MatchesLambda
* Add WireTests.StructureOfStructureArrayArgument
* Add BindGroupValidationTests.BindGroupLayoutCache
This as an API change to get closer to the direction in which WebGPU is
headed. The API change in next.json caused a ton of files to be changed
in the same commit to keep things compiling.
API: the Framebuffer and RenderPass objects are now merged in a single
RenderPassInfo that contains the attachments, loadOps and clear values
for a BeginRenderPass command. The concept of subpass is removed.
The RenderPass creation argument to RenderPipelines is replaced by
explicitly setting the format of attachments for RenderPipeline.
Validation: SetPipeline checks are changed to check that the attachments
info set on a RenderPipeline matches the attachments of the render pass.
Backends: Most changes are simplifications of the backends that no
longer require and indirection to query the current subpass out of the
render pass in BeginSubpass, and don't need to get the attachment info
from a RenderPass when creating RenderPipelines. In the Vulkan backend,
a VkRenderPass cache is added to reuse VkRenderPasses between
RenderPassInfos and RenderPipelines.
Tests and examples: they are updated with the simplified API. Tests
specific to the Framebuffer and RenderPass objects were removed and
validation tests for RenderPassInfo were added.
Tested by running CppHelloTriangle on all backends, end2end tests on all
platforms and all examples on the GL backend.
We want all of NXT to have the origin in the top left. OpenGL's origin
is the bottom left instead. We are doing a blit already to decouple
the NXT render targets from the OpenGL default framebuffer. Take
advantage of this and invert the blit to make the OpenGL's backend
origin be top left.
The Swapchain::Configure was changed to not require an initial usage
anymore. Previously the code was doing a transition to this usage
causing the code to now transition to <uninitialized data> usage.
Fix this by deleting code. Also make TextureD3D12 responsible for the
transition to PRESENT.
Making all textures represented by pointers is a problem for Vulkan
where VkImage is a 64bit type and wouldn't fit in a pointer on 32bit
builds. Make texture contain on of each useful type so that each backend
can choose which one it wants to receive.
For the Vulkan backend it will make sense to have the SwapChain be
implemented inside the backend as it will need to interact with a lot of
things there. It will need SwapChainImpl and cannot see utils/ so
SwapChainImpl has to be moved in common/
Also makes SwapChainImpl a function called CreateSwapChainImplementation
as the inheritance was only used to share a static method.
Explicitly configure swap chain usage in bindings and examples
Fix missing case in switch
Make swap chain Present usage implicit

* clang/gcc: enable -pedantic warnings
* suppress a GCC-specific warning in stb_image
* And some clang-specific warnings
* -Wconversion (clang) -Wold-style-cast (clang+gcc)
and fix a few warnings that show up with these (and a few more with
-Wconversion on gcc, even though that's not enabled by default)
* bunch more warnings
* fixes
* remove merge error
