A demo about how to build a real compiler with LLVM libraries, write for the book https://github.com/tuoxie007/play_with_llvm .

$ git clone https://github.com/tuoxie007/play_with_llvm_write_a_real_compiler
$ cd play_with_llvm_write_a_real_compiler
$ cd play
$ ./build.sh
$ ./play

Then a .o file will be wrote in tests/.

1. Open the startup file play/cli.cpp.
2. Change the macro TEST.
3. Rebuild and run.

#define TEST "int_indexer"
//#define TEST "int_pointer_arg"
//#define TEST "delete_ptr"

1. Write a test file in directory play/tests.
2. Save it with extension .play.
3. Change the macro TEST in play/cli.cpp.
4. Rebuild and run.

Have fun!
