From a4136b8c1a4533925af616d4920054c9734a265b Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sat, 13 Jan 2018 10:45:55 -0800 Subject: [PATCH] anv/pass: Store usage in each subpass attachment This requires us to ditch the VkAttachmentReference struct in favor of an anv-specific struct. However, we can now easily identify from just the subpass attachment what kind of an attachment it is. This will make iteration over anv_subpass::attachments a little easier in some case.
