Message : Vulkan: Implement occlusion queries Begin and end queries insert an execution barrier in the command graph to ensure the commands around them are not reordered w.r.t to the query. Also, these commands cannot be recorded in separate secondary command buffers. Therefore, special-function nodes are created to perform the begin and end query calls on the final primary command buffer. Bug: angleproject:2855 Change-Id: Ie216dfdd6a2009deaaf744fd15d2db6899dd93e9 Reviewed-on: https://chromium-review.googlesource.com/c/1259762 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
