SBM is an ObjectWeb's ASM like library to manipulate SPIR-V binary code with Java.
The library uses a visitor model, meaning that SPIR-V modules will be generated/read with objects having a function for each instruction possible in the SPIR-V Specifications (up to 1.1 as to 2017/03/03). Those objects are what are called visitors.
Each visitor function name contains the corresponding instruction name with a few variations:
- OpType<TypeName> instructions are converted to CodeVisitor::visit<TypeName>Type(args...)
- OpExecutionMode does not have the exact same arguments as the corresponding instruction: the operands array is directly accessible in the ExecutionMode object.
The CodeWriter, CodeVisitor, FunctionVisitor, MemoryVisitor, ModuleReaderDispatcher, TypeVisitor and Opcodes classes are generated thanks to Spir-V Spec to Json
