Example 36 with NodeView

use of org.graalvm.compiler.nodes.NodeView in project graal by oracle.

the class IntegerLessThanNode method canonical.

@Override

    NodeView view = NodeView.from(tool);
    ValueNode value = OP.canonical(tool.getConstantReflection(), tool.getMetaAccess(), tool.getOptions(), tool.smallestCompareWidth(), OP.getCondition(), false, forX, forY, view);
