Enum NodeCycles

java.lang.Object

java.lang.Enum<NodeCycles>

org.graalvm.compiler.nodeinfo.NodeCycles

All Implemented Interfaces:

Serializable, Comparable<NodeCycles>

public enum NodeCycles
extends Enum<NodeCycles>

Constants representing an estimation of the number of CPU cycles needed to execute a certain compiler node. See NodeSize for further information on how to determine a value for a new node.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CYCLES_0 Nodes that do not consume any CPU time during the "execution", e.g.
CYCLES_1
CYCLES_1024
CYCLES_128
CYCLES_16
CYCLES_2
CYCLES_256
CYCLES_32
CYCLES_4
CYCLES_512
CYCLES_64
CYCLES_8
CYCLES_IGNORED Nodes for which runtime information is irrelevant and can be ignored, e.g.
CYCLES_UNKNOWN Nodes for which, due to arbitrary reasons, no estimation can be made either (1) statically without inspecting the properties of a node or (2) at all (like e.g.
CYCLES_UNSET The default value of the NodeInfo.cycles() property.

Enum Constant Detail

CYCLES_UNSET

public static final NodeCycles CYCLES_UNSET

The default value of the NodeInfo.cycles() property.

For further information about the use of CYCLES_UNSET see NodeInfo.cycles().

CYCLES_UNKNOWN

public static final NodeCycles CYCLES_UNKNOWN

Nodes for which, due to arbitrary reasons, no estimation can be made either (1) statically without inspecting the properties of a node or (2) at all (like e.g. for an invocation).

Nodes annotated with CYCLES_UNKNOWN should specify the NodeInfo.cyclesRationale() property to clarify why an estimation cannot be done.

CYCLES_IGNORED

public static final NodeCycles CYCLES_IGNORED

Nodes for which runtime information is irrelevant and can be ignored, e.g. for test nodes.

CYCLES_0

public static final NodeCycles CYCLES_0

Nodes that do not consume any CPU time during the "execution", e.g. constants.
