Enum CanonicalizerPhase.CanonicalizerFeature

java.lang.Object

java.lang.Enum<CanonicalizerPhase.CanonicalizerFeature>

org.graalvm.compiler.phases.common.CanonicalizerPhase.CanonicalizerFeature

All Implemented Interfaces:

Serializable, Comparable<CanonicalizerPhase.CanonicalizerFeature>

Enclosing class:

CanonicalizerPhase

public static enum CanonicalizerPhase.CanonicalizerFeature
extends Enum<CanonicalizerPhase.CanonicalizerFeature>

Constants for types of canonicalization that can be performed. Canonicalizable and CanonicalizerPhase combine different optimizations into a single API. This includes global value numbering, strength reductions, stamp based optimizations and many more. This feature enum groups them into different categories.

Enum Constant Detail

READ_CANONICALIZATION

public static final CanonicalizerPhase.CanonicalizerFeature READ_CANONICALIZATION

Determines if CanonicalizerPhase is allowed to canonicalize memory read operations. See CanonicalizerTool.canonicalizeReads().

CFG_SIMPLIFICATION

public static final CanonicalizerPhase.CanonicalizerFeature CFG_SIMPLIFICATION

Determines if the canonicalizer is allowed to change ControlFlowGraph of the currently compiled method. This includes removal/deletion/insertion/etc of FixedNode.

GVN

public static final CanonicalizerPhase.CanonicalizerFeature GVN

Determines if the canonicalizer is allowed to perform global value numbering. See Graph.findDuplicate(Node) for details.

valueOf

public static CanonicalizerPhase.CanonicalizerFeature valueOf(String name)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name
