//===--- HowToUseJIT.cpp - An example use of the JIT ----------------------===//

|

//===----------------------------------------------------------------------===//
|
||||
//
|
||||
// This small program provides an example of how to quickly build a small
|
||||
// module with two functions and execute it with the JIT.
|
||||
//
|
||||
// Goal:
|
||||
// The goal of this snippet is to create in the memory
|
||||
// the LLVM module consisting of two functions as follow:
|
||||
//
|
||||
// int add1(int x) {
|
||||
// return x+1;
|
||||
// }
|
||||
//
|
||||
// int foo() {
|
||||
// return add1(10);
|
||||
// }
|
||||
//
|
||||
// then compile the module via JIT, then execute the `foo'
|
||||
// function and return result to a driver, i.e. to a "host program".
|
||||
//
|
||||
// Some remarks and questions:
|
||||
//
|
||||
// - could we invoke some code using noname functions too?
|
||||
// e.g. evaluate "foo()+foo()" without fears to introduce
|
||||
// conflict of temporary function name with some real
|
||||
// existing function name?
|
||||

This project is a extremely simple example of two things: building an LLVM
|
||||
"project" and using some simple pieces of the LLVM API. The actual executable
|
||||
generated by this project simply emits an LLVM bytecode file to standard output.
|
||||
It is designed to show some basic usage of LLVM APIs, and how to link to LLVM
|
||||
libraries.
