Intro
Inspired by http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1609r0.html.
Complex attempt to implement simplified process of jit compilation for void-template function without use of libdl. Unfortunatelly, it doesn't work.
Details
JIT_DECLARATION create string literal with kept code
JIT_CALL lazily compile template specialization to shared library and load it.
Requirements
- Gcc or Clang (C++17 or higher)
- Cmake 3.12 or higher
Usage
- To declare function that could be possibly jit'ed write
JIT_DECLARATION
(
fun,
template<template params>
void fun(args...) {
}
)
- To run
JIT_CALL(fun, fun<template params>, args...);
Todo
- maintain non-zero count of function args.
- returning value of jit function
- find mangled name in shared library and call it directly.
