-This is an example of Clang based interpreter, for executing standalone C/C++
-programs.
-
-It demonstrates the following features:
- 1. Parsing standard compiler command line arguments using the Driver library.
-
- 2. Constructing a Clang compiler instance, using the appropriate arguments
- derived in step #1.
-
- 3. Invoking the Clang compiler to lex, parse, syntax check, and then generate
- LLVM code.
-
- 4. Use the LLVM JIT functionality to execute the final module.
-
- 5. Intercepting a Win64 library call to allow throwing and catching exceptions
- in and from the JIT.
-
-The implementation has many limitations and is not designed to be a full fledged
-interpreter. It is designed to demonstrate a simple but functional use of the
-Clang compiler libraries.
