Valgrind: Test case 'dEQP-VK.renderpass2.dedicated_allocation.attachment.8.724'.. ==754520== Conditional jump or move depends on uninitialised value(s) ==754520== at 0x575B21C: radv_layout_is_htile_compressed (radv_image.c:1690) ==754520== by 0x572F470: radv_handle_depth_image_transition (radv_cmd_buffer.c:5855) ==754520== by 0x572F2F2: radv_handle_image_transition (radv_cmd_buffer.c:6123) ==754520== by 0x572EEC6: radv_handle_subpass_image_transition (radv_cmd_buffer.c:3385) ==754520== by 0x572A104: radv_cmd_buffer_begin_subpass (radv_cmd_buffer.c:4843) ==754520== by 0x572A007: radv_CmdBeginRenderPass (radv_cmd_buffer.c:4913) ==754520== by 0x572A197: radv_CmdBeginRenderPass2 (radv_cmd_buffer.c:4921) Why false? A renderloop happens when the same attachment is both used as input attachment and output (color, ds) attachment in a subpass. Of course this doesn't happen outside of a renderpass and hence we can initialize it to false at the start of the renderpass.
