OntoTeamCompiler
MiniJava compliler project based on Andrew W. Appel book.
Features
- Lexical analysis with flex
- Syntactic analysis with bison
- Abstract Syntax Tree (AST) generation
- Tree visualization with dot
- Semantic analysis: symbol tables and typechecking
- Intermediate Representation Tree (IRT) generation
- To be continued...
Examples
Consider the following code in MiniJava:
class Factorial{
public static void main(String[] a){
System.out.println(new Fac().ComputeFac(10));
}
}
class Fac {
public int ComputeFac(int num){
int num_aux ;
if (num < 1)
num_aux = 1 ;
else
num_aux = num * (this.ComputeFac(num-1)) ;
return num_aux ;
}
}-
