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

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceShaderExpectAssumeFeaturesKHR

New Enum Constants

• KHR_SHADER_EXPECT_ASSUME_EXTENSION_NAME

• KHR_SHADER_EXPECT_ASSUME_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_EXPECT_ASSUME_FEATURES_KHR

New SPIR-V Capabilities

• ExpectAssumeKHR

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.
