Modifying the shader interface
farnoy opened this issue · comments
Is changing certain aspects of an EntryPoint planned as a feature? Would it be out of scope of this library? I think it would be great to have this as an option, allowing users of spirq to rebind especially descriptor sets, since it's impossible to do that with specialization constants.
My layman opinion is that these would require only slight changes in the bytestream to literal values. These should not modify the sequence of the instruction stream, but there's probably something I'm not seeing.
SPIR-Q is restrained to support query only, post-processing is non-goal of this project. ;)
Though, AFAIK it's not necessary to rebind descriptors in SPIR-V because it's easier to achieve the same over API calls.
That's too bad, but fair enough.
If you're referring to making the decision at the vkPipelineLayout (and by association vkDescriptorSetLayout) level, then there's a performance incentive in keeping them compatible across different programs.
