IfNode class

Represents an if-then-else conditional statement in Balbismo.

An if node implements conditional execution based on a boolean condition. If the condition evaluates to non-zero (true), the then-block is executed. If an else-block is provided and the condition is zero (false), the else-block is executed instead.

Example Balbismo code:

int x = 10;
if (x > 5) {        // This is an IfNode
  printf("Big\n");
} else {
  printf("Small\n");
}

This generates LLVM IR with conditional branches:

%conditionCast.0 = icmp ne i64 %x, 0
br i1 %conditionCast.0, label %then.0, label %else.0
then.0:
  ; then block code
  br label %end.0
else.0:
  ; else block code
  br label %end.0
end.0:
