convert-to-sampled-image pass converts images and/or samplers with given pairs of descriptor set and binding to sampled image. If a pair of an image and a sampler have the same pair of descriptor set and binding that is one of the given pairs, they will be converted to a sampled image. In addition, if only an image has the descriptor set and binding that is one of the given pairs, it will be converted to a sampled image as well. For example, when we have %a = OpLoad %type_2d_image %texture %b = OpLoad %type_sampler %sampler %combined = OpSampledImage %type_sampled_image %a %b %value = OpImageSampleExplicitLod %v4float %combined ... 1. If %texture and %sampler have the same descriptor set and binding %combine_texture_and_sampler = OpVaraible %ptr_type_sampled_image_Uniform ... %combined = OpLoad %type_sampled_image %combine_texture_and_sampler %value = OpImageSampleExplicitLod %v4float %combined ... 2. If %texture and %sampler have different pairs of descriptor set and binding %a = OpLoad %type_sampled_image %texture %extracted_image = OpImage %type_2d_image %a %b = OpLoad %type_sampler %sampler %combined = OpSampledImage %type_sampled_image %extracted_image %b %value = OpImageSampleExplicitLod %v4float %combined ... |
