Change log for January 05, 2019 Vulkan 1.1.97 spec update: * Update release number to 97. Public Issues: * Add a special case to the <<renderpass-compatibility, Render Pass Compatibility>> rules allowing single-subpass renderpasses to be compatible even if they have different resolve attachment references (public issue 835). * Fix the miss shader binding table record address rule in the <<shader-binding-table-indexing-rules, Miss Shaders>> section to index by code:missIndex, not code:sbtOffset (public issue 875). Internal Issues: * Add a missing anchor to the elink:VkSamplerCreateFlagBits language (internal issue 1483). * Add missing implicit valid usage include for slink:VkHdrMetadataEXT and corresponding `noautovalidity` attributes in `vk.xml` for the externally-defined metadata properties (internal issue 1514). * Remove restrictions on the `mask` parameter of SPIR-V's code:OpGroupNonUniformXor in the <<spirvenv-module-validation, Validation Rules within a Module>> appendix (internal merge request 2971). * Restore `noautovalidity` attribute for slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings in `vk.xml` (internal merge request 2975). * Update copyright dates on Khronos-copyrighted files to 2019 (internal merge request 2980). New Extensions: * `VK_KHR_depth_stencil_resolve` * `VK_EXT_buffer_device_address` * `VK_EXT_memory_budget` * `VK_EXT_memory_priority` * `VK_EXT_validation_features`

Change log for September 29, 2018 Vulkan 1.1.86 spec update: * Update release number to 86. Internal Issues: * Add new <<resources-image-creation-limits, Image Creation Limits>> section and reference that from valid usage statements, reducing combinatorial complexity of extension-dependent VUs. Also fixes some underspecified limits (such as pname:maxMipLevels) in the VUs for slink:VkImageCreateInfo when slink:VkExternalMemoryImageCreateInfo::pname:externalMemoryHandles contains multiple bits, and fixes incorrectly (and underspecified) limits when an Android external format is used (internal issue 1370). * Remove unused "`Fragment Area Granularity`" glossary entry accidentally introduced in the 1.1.85 update. New Extensions: * `VK_KHR_driver_properties` * `VK_KHR_shader_atomic_int64` * The specification sources contain text for another extension, `VK_EXT_image_drm_format_modifier`, but this extension is not yet complete, and is marked disabled in `vk.xml`. The extension will be enabled, and become part of the spec, only when the authors decide it is ready.

Change log for October 7, 2018 Vulkan 1.1.87 spec update: * Update release number to 87. Public Issues: * Merge flink:vkCmdPipelineBarrier self-dependency barrier VUs referring to the same subpass dependency (public pull request 756). * Describe default value of `"optional"` attribute in the registry schema document (public issue 769) * Fix links in <<VK_NVX_raytracing>> extension (public pull request 805). * Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814 - does not close this, however). * Fix missing endif in Image Creation block (public issue 817). Internal Issues: * Clarify that the compressed texture formats corresponding to <<features-features-textureCompressionETC2>>, <<features-features-textureCompressionASTC_LDR>>, and <<features-features-textureCompressionBC>> is not contingent on the feature bits, and may be supported even if the features are not enabled (internal issue 663). * Clarify that code:FragStencilRefEXT is output only in the <<interfaces-builtin-variables, Built-In Variables>> section (internal issue 1173). * Identify and correct many overly-aggressive uses of "`undefined`", and narrow them down, where straightforward to do so. Mark such resolved uses of "`undefined`" with the custom undefined: macro. Add a new <<writing-undefined, Describing Undefined Behavior>> section (internal issue 1267). * Don't require code:inline_uniform_block descriptors to be populated before use in the flink:vkAllocateDescriptorSets section (internal issue 1380). * Allow suppressing inline SVG images by controlling this with an attribute set in the Makefile, rather than the explicit [%inline] directive (internal issue 1391). * Mark 'Khronos' as a registered trademark in several places, now that it is one. * Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL naming of the compare exchange op when referring to the SPIR-V op. * Specify in the flink:vkGetPhysicalDeviceQueueFamilyProperties section that all implementations must support at least one queue family, and that every queue family must contain at least one queue. * Make slink:VkPipelineDynamicStateCreateInfo::pname:dynamicStateCount, slink:VkSampleLocationsInfoEXT::pname:sampleLocationsPerPixel, and slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to fix bogus implicit valid usage checks that were causing failures in the conformance tests. * Fix vendor tag in reserved extension 237 constants. Does not affect anything since it's just a placeholder, but this should avoid further comments. * Minor markup fixes in some extension appendices. New Extensions: * `<<VK_FUCHSIA_imagepipe_surface>>`

Public Issues: * Fix missing markup in flink:vkDestroyPipelineLayout valid usage statement (pull request 882). * Add missing contributors for `<<VK_EXT_buffer_device_address>>` (public pull request 891). Internal Issues: * Detect nested bullet points in valid usage blocks and warn about them during VUID assignment (internal issue 1382). * Update the style guide to document the process for reserving new bits in bitmask types (internal issue 1411). * Clarify for slink:VkApplicationInfo::pname:apiVersion and in the <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>> section when it is valid for an application to use a certain version of Vulkan API functionality (for an instance and for a device/physical device); and when the validation layers must generate an error (internal issue 1412). * Add optional <<memory-model-availability-visibility, transitive availability/visibility operations to the memory model, including a new pname:vulkanMemoryModelAvailabilityVisibilityChains feature for slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (internal issue 1460). * Add the code:StorageBuffer storage class to those in the <<interfaces-resources-descset, Descriptor Set Interface>> (internal issue 1480). * Add missing `returnedonly` tags for a number of returned extension structures that can be passed in pname:pNext chains (internal issue 1515). * Clean up and rearrange some spec language for slink:VkRenderPassCreateInfo and slink:VkAttachmentReference.txt (internal issue 1522). * Correctly round the code:OpVectorTimesScalar and code:OpMatrixTimesScalar SPIR-V operations in the <<Precision of core SPIR-V Instructions>> table (internal merge request 2996). * Work around cases in flink:vkCmdBeginTransformFeedbackEXT, flink:vkCmdEndTransformFeedbackEXT, and slink:VkPipelineCoverageModulationStateCreateInfoNV where an array parameter is `optional` but the length is not in `vk.xml`. This is an interim fix using `noautovalidity` + handcoded VU replacing those that should be autogenerated (internal issue 2944 and https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/480). * Remove redundant capability validation of the code:float16 and code:int8 SPIR-V capabilities from the <<spirvenv-capabilities, Capabilities>> section, since they are already covered in the preceding table. * Update check_spec_links script, including validation for reference page open blocks. Fix errors identified by the script.

This extension advertises the SPIR-V *Int64Atomics* capability for Vulkan,
which allows a shader to contain 64-bit atomic operations on signed and
unsigned integers.
The supported operations include OpAtomicMin, OpAtomicMax, OpAtomicAnd,
OpAtomicOr, OpAtomicXor, OpAtomicAdd, OpAtomicExchange, and
