In such case: dEQP-VK.pipeline.blend.dual_source.format.a2r10g10b10_unorm_pack32.states.color_dc_ca_rsub_alpha_dc_s1a_rsub-color_cc_da_min_alpha_ca_1ms1a_max-color_1msc_1mdc_max_alpha_cc_sa_rsub-color_da_o_sub_alpha_z_dc_rsub

As the next drawcall depends on the previous attachment result. No barrier between each drawcall, how can we guarantee the resource dependence?
