Description

This extension provides a mechanism for caching the results of potentially expensive internal validation operations across multiple runs of a Vulkan application. At the core is the VkValidationCacheEXT object type, which is managed similarly to the existing VkPipelineCache.

The new struct VkShaderModuleValidationCacheCreateInfoEXT can be included in the pNext chain at vkCreateShaderModule time. It contains a VkValidationCacheEXT to use when validating the VkShaderModule.
