KHRShaderSubgroupUniformControlFlow (LWJGL 3.3.1 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.KHRShaderSubgroupUniformControlFlow

```
public final class KHRShaderSubgroupUniformControlFlow
extends java.lang.Object
```
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).
