Tiny Tiger Compiler

Tiny Tiger

Compiler of Tiny Tiger using LLVM. For language sepeficication please refer to Morden Compiler Implementation in C.

Introduction

Everything is well, including record, array and nested function. Input or empty string comparision might have some problems to fix. (Therefore merge.tig is not working.)

Usage

• Compile it with Qt.
• Run it

   ./TinyTiger

• Input the tiger program, click on compile button. (Run is button not working.)
• On the console, it will output the AST tree and IR code if no syntax or sematic error. And output.o is generated.
• Note that if there should not be any generation error output before IR code. If so, report it as a bug with the tiger source code.
• Then link the tiger object file with runtime library.

   clang++ output.o runtime.o

  PLEASE USE C++ COMPILER (clang++ or g++ or others).
• Run the Tiger program

   ./a.out
  

Know Issue

• If syntax error occurs, you must restart the program. Problem might cause by Pipe or the stringstream(not being cleared after error) in yacc code.
• Merge.tig is not running. Might cause by empty string comparision?

TODO

• Output IR code in the bottom widget in the main windows via pipe.
• Syntax error alert with lineno.
• Add type to AST visualization.
• Editor is not good enough.
• MIGHT automatically generate executive file rather than object file that has to be linked.
