The Vulkan spec states that VkPipelineLayout objects must not be destroyed while any command buffer that uses them is in the recording state, but it permits them to be destroyed otherwise. This means that applications are allowed to free pipeline layouts after command recording is finished even if there are pipeline objects that still exist and were created with these layouts. There are two solutions to this, one is to use reference counting on pipeline layout objects. The other is to avoid holding references to pipeline layouts where they are not really needed. This patch takes a step towards the second option by making the pipeline shader compile code take pipeline layout from the VkGraphicsPipelineCreateInfo provided rather than the pipeline object. A follow-up patch will remove any remaining uses of the layout field so we can remove it from the pipeline object and avoid the need for reference counting. v2: Use ANV_FROM_HANDLE, remove unnecessary braces (Jason) Suggested-by: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Jason Ekstrand <jason@jlekstrand.net>
