Introduce spirv-diff (#4611) spirv-diff is a new tool that produces diff-style output comparing two SPIR-V modules. The instructions between the src and dst modules are matched as best as the tool can, and output is produced (in src id-space) that shows which instructions are removed in src, added in dst or modified between them. The order of instructions are not retained. Matching instructions between two SPIR-V modules is not trivial, and thus a number of heuristics are applied in this tool. In particular, without debug information, it's hard to match functions as they can be reordered. As such, this tool is primarily useful to produce the diff of two SPIR-V modules derived from the same source. This tool can be useful in a number of scenarios: - Compare the SPIR-V before and after modifying a shader - Compare the SPIR-V produced from a shader before and after compiler codegen changes. - Compare the SPIR-V produced from a shader before and after some transformation or optimization. - Compare the SPIR-V produced from a shader with different compilers. 2022-02-02 15:33:18 +00:00			`# To aid debugging no-dbg variants, the temporary files used to strip debug information are placed`
