This extension adds Vulkan support for the SPV_EXT_demote_to_helper_invocation SPIR-V extension. That SPIR-V extension provides a new instruction OpDemoteToHelperInvocationEXT allowing shaders to “demote” a fragment shader invocation to behave like a helper invocation for its duration. The demoted invocation will have no further side effects and will not output to the framebuffer, but remains active and can participate in computing derivatives and in group operations. This is a better match for the “discard” instruction in HLSL.

Functionality in this extension is included in core Vulkan 1.3, with the EXT suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
