# x86compiler
A toy compiler (with SLR parser, for x86_64, written in python).

## Usage:

python compiler.py SOURCE_FILE

## Examples:

**Variable Declaration, Assignment, and Loading**
 
    {
    int a;
    a = 6;
    iprint(a);
    }
-> 6

**Arithmetic Operations**

{
      int a;
      int b;
      a = 7;
      b = 3;
      iprint(a+1);
      iprint(b+1);
      iprint(a+b);
      iprint(a-b);
      iprint(a*b);
      iprint(a/b);
    }

**Variable Scopes**

{
      int a;
      int b;
      a = 111;
      b = 123;
      iprint(a);
      iprint(b);
      {
        int a;
        a = 777;
        iprint(a);
        iprint(b);
      }
      iprint(a);
      iprint(b);
    }

**Functions**

{
      int a[3];
      int b;
      int f(int x, int y){
        int z;
        z = x * y;

{
        int a;
        int f(int n){
            if(n<1)
                return 1;
