A runtime SPIR-V assembler
8cfe8badf7
Provides shorthands for specific signedness, so that usage code doesn't need to explicitly use raw booleans. TypeUInt(32), is easier to gloss than TypeInt(32, false), especially for those not familiar with the API. |

Sirit
A runtime SPIR-V assembler. It aims to ease dynamic SPIR-V code generation
without calling external applications (like Khronos' spirv-as)
Its design aims to move code that does not belong in the application to the library, without limiting its functionality.
What Sirit does for you:
- Sort declaration opcodes
- Handle types and constant duplicates
- Emit SPIR-V opcodes
What Sirit won't do for you:
- Avoid ID duplicates (e.g. emitting the same label twice)
- Dump code to disk
- Handle control flow
- Compile from a higher level language
It's in early stages of development, many instructions are missing since they are written manually instead of being generated from a file.
Example
class MyModule : public Sirit::Module {
public:
MyModule() {}
~MyModule() = default;
void Generate() {
AddCapability(spv::Capability::Shader);
SetMemoryModel(spv::AddressingModel::Logical, spv::MemoryModel::GLSL450);
auto main_type{TypeFunction(TypeVoid())};
auto main_func{OpFunction(TypeVoid(), spv::FunctionControlMask::MaskNone, main_type)};
AddLabel(OpLabel());
OpReturn();
OpFunctionEnd();
AddEntryPoint(spv::ExecutionModel::Vertex, main_func, "main");
}
};
// Then...
MyModule module;
module.Generate();
std::vector<std::uint32_t> code{module.Assemble()};
