Tiger-Compiler

A Tiger compiler for the x86 architecture, implemented in C++, as described in the book "Modern Compiler Implementation" by Andrew Appel.

Compiler steps

1. Tokenize the source code and build the corresponding AST (Syntax, AST)
2. Set escaping variables in the AST (Escapes)
3. Semantic check (Semantic)
4. Translate the AST into the IRT (IRT, Frame, Translation)
5. Canonize the IRT (Canon)
6. Tile out the canonized IRT into generic assembly instructions (Munch, Frame)
7. Construct a control flow graph from the sequence of instructions and do liveness analysis (Liveness)
8. Select a register to hold each of the variables and temporaries (RegAlloc)

Usage

• Use make test to compile a unit testing executable.
• Use make to compile the Compiler, currently reads the source code from test.file.
