Description

This extension allows the use of the SPV_KHR_relaxed_extended_instruction extension in SPIR-V shader modules.

It adds a new SPIR-V instruction, which allows some usage of forward references in non-semantic instruction sets. This extensions interacts with the SPV_KHR_non_semantic_info extension, hence with VK_KHR_shader_non_semantic_info.

New Structures

• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
