Description
This extension allows the use of the SPV_KHR_subgroup_uniform_control_flow
SPIR-V extension in shader modules.
SPV_KHR_subgroup_uniform_control_flow provides stronger guarantees that
diverged subgroups will reconverge.
Developers should utilize this extension if they use subgroup operations to reduce the work performed by a uniform subgroup. This extension will guarantee that uniform subgroup will reconverge in the same manner as invocation groups (see “Uniform Control Flow” in the Khronos SPIR-V Specification).
