Example 7 with OptimisationStrategy

use of com.redhat.ceylon.compiler.java.codegen.Operators.OptimisationStrategy in project ceylon-compiler by ceylon.

the class ExpressionTransformer method transform.

// Comparison operators

    // The only thing which might be unboxed is boolean, and we can follow the rules of == for optimising it,
    // which are simple and require that both types be booleans to be unboxed, otherwise they must be boxed

    JCExpression left = transformExpression(op.getLeftTerm(), optimisationStrategy.getBoxingStrategy(), null);
