Runtime descriptor arrays should be used for descriptor bindings with a variable count.
Support for SpvCapabilityRuntimeDescriptorArrayEXT is required by the Vulkan spec as part of descriptor indexing support.
The current implementation depends on a separate array declaration for each range because binding_base_idx is stored in the array data. This occurs in practice because binding.count is always different. Use of runtime arrays eliminates the count from the key, so binding_base_idx must be separated from the array data.

That's a consequence of introducing binding offsets, isn't it? If that's the case, it may be helpful to clarify that in the commit message.

Conceptually, this is starting to look a fair bit like the existing vkd3d_shader_parameter mechanism. What would it take to extend that mechanism to work for descriptor offsets?

I think the "_symbol" in "vkd3d_descriptor_array_symbol" may be a little misleading; this is structure is not a symbol in the way that struct vkd3d_symbol is, or struct vkd3d_symbol_descriptor_array for that matter.
- /* The array declaration which this symbol maps to, or NULL. */
- const struct vkd3d_symbol *descriptor_array;
- /* descriptor_array.symbol is the array declaration which this symbol maps to, or NULL. */
- struct vkd3d_descriptor_array_symbol descriptor_array;
And the comment here just emphasises that.
I'm wondering, could we just store the contents of struct vkd3d_descriptor_array_symbol in the vkd3d_symbol_register_data and vkd3d_symbol_resource_data structures?
