Method AddLazyFunctionGenerator

AddLazyFunctionGenerator(String, LazyFunctionCompiler, IntPtr)

Add a lazy function generator

Declaration

void AddLazyFunctionGenerator(string name, LazyFunctionCompiler generator, IntPtr context)

Parameters

String	name	name of the function
LazyFunctionCompiler	generator	Generator that will generate the bit-code module for the function on demand
IntPtr	context	Opaque context to pass to generator when the function is first called

Remarks

A lazy function generator is an engine callback that is called when the JIT engine first encounters a symbol name during execution. If the function is never called, then the code is never generated (e.g. this is the real "JIT" part of a JIT engine.)

The generator generates the IR module for the function. Typically, the generator is a closure that captured the AST for the language and generates the IR from that state. However, the context is available as a means to identify the function to generate.
