Description

This extension allows the use of the SPV_KHR_expect_assume extension in SPIR-V shader modules which enables SPIR-V producers to provide optimization hints to the Vulkan implementation.

New Structures

New Enum Constants

  • VK_KHR_SHADER_EXPECT_ASSUME_EXTENSION_NAME

  • VK_KHR_SHADER_EXPECT_ASSUME_SPEC_VERSION

  • Extending VkStructureType:

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_EXPECT_ASSUME_FEATURES_KHR

New SPIR-V Capabilities

Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
