Shahbaz Youssefi ea71c6b6 2021-01-12T14:13:35 Vulkan: Emulate R32F images with R32UI GL requires that imageAtomicExchange be supported for r32f formats. However VK_FORMAT_FEATURE_STORAGE_*_ATOMIC_BIT is nearly unsupported everywhere without some Vulkan extension that brings in unnecessary support. This GL feature is emulated by transforming the shader to use r32ui for all images that originally specified r32f. floatToUintBits and uintBitsToFloat is used to maintain correct usage of the image* builtin functions.

Shahbaz Youssefi 60015ff6 2021-01-14T02:03:07 Vulkan: Redo RewriteStructSamplers This transformation is split into two. The first transformation solely takes out the samplers out of structs, and potentially generates array of array of samplers. A second transformation is added that takes any array of array of opaque uniforms and flattens it. A follow up change will simplify RewriteAtomicCounters which also handles array of arrays (which is no longer possible), and removes dependency on shaderStorageBufferArrayDynamicIndexing.
