Worked on enhancing the SPIR-V validator in the KhronosGroup/SPIRV-Tools repository by implementing support for ArrayStrideIdEXT on structs containing descriptor types. This involved recursively validating nested types within structs to ensure compliance with SPV_EXT_descriptor_heap, addressing a root-cause validation gap that previously led to false negatives. The solution included adding a regression test for runtime arrays of structs with descriptors, thereby improving validation coverage and reliability for downstream graphics and compute pipelines. The work was carried out using C++ and focused on SPIR-V validation and shader programming, contributing to more robust and interoperable SPIR-V tooling.
