3// The test check that if an array is used in function parameter, we don't decorate it with array stride decoration.
4
5// The reason we have to check the SPIRV instead of using spirv-val is because slang uses spv1.6 as the target_env,
6// but the issue only occurs when the target_env is vulkan1.2+
