Add ExternalDependencies (Debug) scheme to ExternalDependencies Xcode project.
Add --debug option to fetchDependencies script.
Support Release, Debug & Latest directories in External/build directory.
Enable DEPLOYMENT_POSTPROCESSING build setting when compiling
SPIRV-Tools to avoid warning spam when building dylibs.
Disable visibility warnings when building MoltenVKShaderConverter
in Release mode from external libraries built in Debug mode.
Always use -Xlinker -w option when creating dylibs to disable visibility warnings.
Add SPIRVToMSLConverterOptions::platform to track platform. Default to build platform.
Update default SPIRVToMSLConverterOptions MSL version to 2.1.
MoltenVKShaderConverter test MSL compilation use same MSL version as conversion.
Default min perf tracking value to 0.0.
SPIRVToMSLConverter.h reference spirv.hpp via SPIRV-Cross framework.
Update What's New document.
In a tessellated draw, the vertex shader will take a `device` pointer to
the vertex count. It must be a `device` pointer, because the `constant`
AS on Mac requires 256-byte alignment, which we cannot guarantee,
particularly with an indirect draw. But, the `setVertexBytes:...` method
cannot be used with the `device` AS. So, we need yet another temporary
buffer to hold this value in the `device` AS.
Fixes#566.
Test for _pMetalFeatures->layeredRendering before setting
MTLRenderPassDescriptor.renderTargetArrayLength.
Change NSString comparisons using isEqualTo: to isEqualToString:.
Sometimes, the `CAMetalLayer` backing a view can be replaced--for
example, when the window is moved to another screen, or the style bits
on the window are changed. In that case, we must allow the client the
opportunity to recreate the surface and swapchain.
Layer-backed views always set themselves as the layer's delegate; we use
this fact to Key-Value Observe the view's `layer` property.
Other alternatives considered:
* Registering for `NSViewGlobalFrameDidChange` notifications. Aside from
only working on macOS, this doesn't actually catch every case where we
want to report a lost surface. I'm not even sure it works at all for
Metal.
* Holding a reference to the view, and checking when its layer property
has changed.
* Holding a weak reference to the layer; that way, the reference will
become `nil` when the layer is replaced. But this requires ARC.
Some projects also link against SPIRV-Cross statically, and in order to
avoid ABI conflicts, we should use a private namespace for the
SPIRV-Cross dependency to avoid bugs. See SPIRV-Cross issue #902 for
more information. The new namespace is MVK_spirv_cross, and the code
now makes use of the SPIRV_CROSS_NAMESPACE macro rather than spirv_cross.
The resource options must match between an `MTLBuffer` and any linear
texture created from it. Further, to be writable, the
`MTLTextureDescriptor` should have the `MTLTextureUsageShaderWrite` bit
set.
Fixes#542.
graphics pipeline during a compute stage.
MVKPushConstantsCommandEncoderState test for tessellation only during graphics stages.
Guard against possible missing graphics pipeline even during graphics stages.
