Example 1 with Loop

use of ast.Expression.Loop in project L42 by ElvisResearchGroup.

the class Desugar method visit.

public Expression visit(While s) {
    Expression cond = Desugar.getMCall(s.getP(), s.getCond(), "#checkTrue", Desugar.getPs());
    RoundBlock b = Desugar.getBlock(s.getP(), cond, s.getThen());
    Loop l = new Loop(b);
    Type _void = Type.immVoid;
    Expression.Catch k = Desugar.getK(s.getP(), SignalKind.Exception, "", _void, Expression._void.instance);
    RoundBlock b2 = Desugar.getBlock(s.getP(), l, Collections.singletonList(k), Expression._void.instance);
    return b2.accept(this);
}
