Description
This extension adds Vulkan support for the
SPV_KHR_terminate_invocation
SPIR-V extension. That SPIR-V extension provides a new instruction,
OpTerminateInvocation, which causes a shader invocation to immediately
terminate and sets the coverage of shaded samples to 0; only
previously executed instructions will have observable effects. The
OpTerminateInvocation instruction, along with the
OpDemoteToHelperInvocation instruction from the
VK_EXT_shader_demote_to_helper_invocation
extension, together replace the OpKill instruction, which could behave
like either of these instructions. OpTerminateInvocation provides the
behavior required by the GLSL discard statement, and should be used
when available by GLSL compilers and applications that need the GLSL
discard behavior.

VkPhysicalDeviceShaderTerminateInvocationFeaturesKHR - Structure
describing support for the SPIR-V SPV_KHR_terminate_invocation
extension
Members
The members of the PhysicalDeviceShaderTerminateInvocationFeaturesKHR
structure describe the following feature:
Description
If the PhysicalDeviceShaderTerminateInvocationFeaturesKHR structure is
included in the pNext chain of
PhysicalDeviceFeatures2,
it is filled with a value indicating whether the feature is supported.
PhysicalDeviceShaderTerminateInvocationFeaturesKHR can also be
included in the pNext chain of DeviceCreateInfo
to enable the features.
