When HW binning is used tile loads/stores could be skipped if there is no geometry in the tile. Loads could be skipped when: - The attachment won't be resolved, otherwise if load is skipped there would be holes in the resolved attachment; - There is no vkCmdClearAttachments afterwards since it is likely a partial clear done via 2d blit (2d blit doesn't produce geometry). Stores could be skipped when: - The attachment was not cleared, which may happen by load_op or vkCmdClearAttachments; - When store is not a resolve. I chose to predicate each load/store separately to allow them to be skipped when only some attachments are cleared or resolved. Gmem loads are moved into separate cs because whether to emit CP_COND_REG_EXEC depends on HW binning being enabled and usage of vkCmdClearAttachments. CP_COND_REG_EXEC predicate could be changed during draw_cs only by perf query, in such case the predicate should be re-emitted. (At the moment it is always re-emitted before stores) Signed-off-by: Danylo Piliaiev <dpiliaiev@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15974>
