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.
