- Ensure Vulkan public symbols are not stripped from the library when
statically linked to an app that calls all Vulkan functions dynamically.
- Per Vulkan 1.2 spec, support calling vkGetInstanceProcAddr() with a
null instance, when vkGetInstanceProcAddr itself is the function name.
- Replace uses of strcmp() with mvkStringsAreEqual() to protect against
null pointers, and provide a direct bool output (unrelated cleanup).
- Fix Metal validation error caused by CAMetalDrawable released before
MTLCommandBuffer is finished using it.
- When presenting, MVKPresentableSwapchainImage retains in-flight
CAMetalDrawable until MTLCommandBuffer completion.
- Fix memory leak of MVKFences and MVKSemaphores when a
swapchain image is acquired more than it is presented.

semaphores when it is destroyed.
- Update MoltenVK version to 1.2.2.
Metal uses MTLRenderPassDescriptor properties renderTargetWidth,
renderTargetHeight, and renderTargetArrayLength to preallocate tile memory
storage on machines using tiled rendering. This memory preallocation is not
necessary if we are not rendering to attachments, and some apps actively
define extremely oversized framebuffers when they know they are not rendering
to actual attachments, making this internal tile memory allocation even more
wasteful, occasionally to the point of triggering OOM crashes.
Update MoltenVK version to 1.2.2.
of VK_KHR_shader_float_controls.
The introduction of shaderSignedZeroInfNanPreserveFloat32 was causing Metal
fast math to be aggressively disabled by the use of SignedZeroInfNanPreserve
in shaders in some apps, causing a regression in shader performance in those apps.
- Change MVKConfiguration::fastMathEnabled from bool to enumeration to distinguish
between always using fast math or allowing shaders to selectively disable it.
- Default value to fast math always.
Push constants and attachment clearing can temporarily override Metal buffer
bindings for descriptor sets and vertex attributes. Mark the overridden buffer
bindings and ensure they are reinstated when the pipeline is updated.
- Add MVKMTLBufferBinding::isOverridden to track if buffer binding is
temporarily overridden.
- Rename MVKResourcesCommandEncoderState::markIndexDirty()
to markBufferIndexOverridden() to mark buffer bindings as overridden.
- Rename MVKGraphicsResourcesCommandEncoderState::markBufferIndexDirty()
to markBufferIndexOverridden().

- Merge branch from master.
- Add MVKPrefillMetalCommandBuffersStyle enumeration to enable prefilling,
and configure memory recovery options.
- Redefine MVKConfiguration::prefillMetalCommandBuffers as a value from
MVKPrefillMetalCommandBuffersStyle instead of a simple boolean. Set the
values of MVKPrefillMetalCommandBuffersStyle and the default value of
MVKConfiguration::prefillMetalCommandBuffers to be compatible with
legacy use of this setting as a simple enable/disable boolean value.
- MVKCommandEncoder track prefill style, and support option to maintain
a Metal autorelease pool that is created on vkBeginCommandBuffer()
and drained on vkEndCommandBuffer(), when prefiling a command buffer
from a single thread, and an option to wrap each command addition in
a separate @autoreleasepool{} scope to create and drain an autorelease
pool at every command addition to the Vulkan command buffer, when
prefilling a single command buffer from multiple threads.

When presenting drawables in the future, the MVKPresentableSwapchainImage
and MVKSwapchain were both being retained by the drawable-presented callback,
so that the presentation timing info can be recorded on the swapchain.
Unfortunately, in the case where the presentation timing is set far enough
into the future (I'm looking at you CTS), the swapchain, and even the
CAMetalLayer's view may be destroyed, causing occasional bad access crashes.
- MVKSwapchainImage don't retain() the swapchain, and move clearing the
swapchain from the destructor to destroy(), so the MVKSwapchain is not
necessarily retained by the MVKSwapchainImage, for a drawable being
presented in the future.
- MVKSwapchainImage add a lock around clearing swapchain and accessing
it from callbacks.
- Add lockable releaseLayer() function in both MVKSwapchain and MVKSurface,
which is called from both layer observer and destructor, to handle race
conditions better.
- MVKSwapchain::initCAMetalLayer() call MVKSurface::getCAMetalLayer() only once.
- Update MoltenVK version to 1.1.12.
- Update What's New document.
This fixes an earlier regression, where when only the offset changes in
a buffer descriptor, the binding is not marked dirty if the same Metal
binding index is used by a push constant in between descriptor bindings.
- MVKPushConstantsCommandEncoderState::markDirty() call resource encoder
state markPushConstantBinding() to find and mark dirty descriptor that
uses same Metal index as a push constant binding.
- Add MVKResourcesCommandEncoderState::markMetalBufferIndexDirty() to
find and mark dirty a descriptor buffer binding that uses
- MVKResourcesCommandEncoderState::bind() use range-based-for-loop
for consistency (unrelated).
- MVKDescriptorPool::reset() don't waste time freeing
descriptor sets that were never allocated.
- If descriptor set could not be allocated, set availability bit (unrelated).
- MVKBitArray add _lowestNeverClearedBitIndex to track the lowest bit index
that has not been cleared since last reset.
- MVKBitArray rename _minUnclearedSectionIndex to _clearedSectionCount for clarity.
- MVKBitArray use _clearedSectionCount and _lowestNeverClearedBitIndex to optimize
operation of setting or clearing all bits.
- MVKBitArray::setBit() ensure we don't try to change a bit that is out of range.
- MVKBitArray::resize() no-op if size doesn't actually change.
- MVKQueue don't include object pointer in error log, so CTS log results
are consistent across multiple CTS runs (unrelated).
- Add [CAMetalLayer screenMVK] extension method to retrieve screen.
- If the layer has a delegate view, use it to locate the screen, otherwise
revert to iterating across windows, looking for the CAMetalLayer, to identify
the window the layer is in, from which to retrieve the screen.
- Fix the iteration of the layer hierarchy, to accommodate that Apple may
add superlayers to the CAMetalLayer under the covers.
- Update MoltenVK_Runtime_UserGuide.md to encourage the app to ensure the view
is the delegate of the CAMetalLayer, to more efficiently access the screen.
- DemoView implements NSViewLayerContentScaleDelegate protocol to update
[CAMetalLayer contentsScale] property when moved between screens.
- Log contentsScale value during swapchain creation.
- Remove a few unnecessary inline declarations.
When checking query wait completion, all queries were previously
checked for Available status, and blocked until all became Available.
However, only queries that were encoded to be written should be checked.
It is okay for queries that are not encoded to be written to remain in
Initial state, and not block the wait.
Support by the MTLDevice for Metal Tier 2 argument buffers has an
impact on both descriptor indexing and buffer device address support.
Add MVKPhysicalDeviceMetalFeatures::argumentBuffersTier, to track
the MTLDevice argument buffers support tier, set it from
[MTLDevice argumentBuffersSupport], and subsequently enable support for
VK_KHR_buffer_device_address and VK_EXT_buffer_device_address extensions,
and set descriptor indexing resource counts, based on it.
Update documentation requirements.
Add MVKPhysicalDeviceMetalFeatures::shaderBarycentricCoordinates,
enable it based on [MTLDevice supportsShaderBarycentricCoordinates],
and subsequently enable support for VK_KHR_fragment_shader_barycentric
and VK_NV_fragment_shader_barycentric extensions, based on it.
- Update to latest SPIRV-Cross to support `SPV_KHR_physical_storage_buffer`
for `VK_KHR_buffer_device_address` and `VK_EXT_buffer_device_address`
- Add support for `VK_EXT_buffer_device_address` extension.
- Advertise support for `VK_KHR_buffer_device_address`
and `VK_EXT_buffer_device_address` on macOS 12.5.
- Add appropriate extension reporting and enablement for
`VkPhysicalDeviceBufferDeviceAddressFeatures`,
`VkPhysicalDeviceBufferDeviceAddressFeaturesEXT`, and
`VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR`.
- Support reading `VkMemoryAllocateFlagsInfo` to identify memory allocations that
need to support buffer pointer access (in case needed in future on non-shared memory).
- Update `Whats_New.md` and `MoltenVK_Runtime_UserGuide` documents.
- Update minimum Xcode deployment targets to macOS 10.13, iOS 11, and tvOS 11,
to avoid Xcode build warnings.
- Add support for MTLLanguageVersion3_0 enumeration.
- Build efficiencies:
- Build scripts create_dylib.sh and gen_moltenvk_rev_hdr.sh
only run if build dependencies require it.
- Packaging and copy_to_staging.sh scripts are too complex to define dependencies,
and are fast, so configured to run every time, to avoid build warning.
- Replace use of deprecated sprintf() with snprintf().
- Replace use of deprecated kIOMasterPortDefault with kIOMainPortDefault.
- Support old-style GPU debug capture only if building for earlier minimum
deployment targets, to avoid deprecation warning.
- Update minimum Xcode deployment targets of Cube demo to macOS 10.14, iOS 12,
and tvOS 12, to avoid Xcode build warning regarding MTLSharedEvent in .
- Update README.md document regarding minimum Xcode deployment targets.
