Compile CPL code into quadruples intermediate code (to give to a back end compiler)
To compile a CPL file, run python compile.py path/to/cpl_file.
The quad code will be generated in a file called "outfile.quad"
Example of compiling this CPL code:
a, b: float;
{
input(a);
input(b);
b = static_cast<int> (a) + b;
switch (a+b){
case 1:
a = 1;
output(a);
case 2:
a = 2;
output(a);
case 3:
a = 3;
output(a);
break;
default:
a = 10;
output(a);
}
if (a>5+b) {
b = b+5;
a = b;
output(b);
}
else {
b = b +3;
output(a);
}
while (a+b>3){
a = 1;
break;
b = 2;
}
}
Output:
1: RINP a
2: RINP b
3: RTOI t0 a

5: IASN b t1
