CLI tool to generate C++ / SPIR-V enumerations and tables for SpvGenTwo

The generated Spv.h, Glsl.h and OpenCl.h have no dependencies and are just plain C++11 which can be used outside of SpvGenTwo. Grammar.h/cpp are made specifically for SpvGenTwo and are of little use otherwise.

Spv.h is compatible to the officical spirv.hpp11 (just need to forward the spvgentwo namespace) and has some extras like ExtensionNames string table and helper functions like HasResult(Op) etc.

Consumes SPIR-V machine-readable JSON grammars:

• spirv.core.grammar.json
• extinst.opencl.std.100.grammar.json
• extinst.glsl.std.450.grammar.json

I was to lazy to write the generated text to the file direclty, so the tool just prints it to stdout and you have to pipe it into a file.

• --defs generates a header like spirv.hpp11 but with some extras
• --header generates Grammar.h
• --cpp generates Grammar.cpp (the main lookup table for SpvGenTwo)

Example usage:

rustspvgen.exe spirv.core.grammar.json --defs > C:\Users\Fabian\Projects\Proto\SpvGenTwo\lib\include\spvgentwo\Spv.h
rustspvgen.exe spirv.core.grammar.json --header > C:\Users\Fabian\Projects\Proto\SpvGenTwo\lib\include\spvgentwo\Grammar.h
rustspvgen.exe spirv.core.grammar.json extinst.glsl.std.450.grammar.json extinst.opencl.std.100.grammar.json --cpp > C:\Users\Fabian\Projects\Proto\SpvGenTwo\lib\source\Grammar.cpp
rustspvgen.exe extinst.glsl.std.450.grammar.json --defs > C:\Users\Fabian\Projects\Proto\SpvGenTwo\lib\include\spvgentwo\Glsl.h
rustspvgen.exe extinst.opencl.std.100.grammar.json --defs > C:\Users\Fabian\Projects\Proto\SpvGenTwo\lib\include\spvgentwo\OpenCl.h
