Class SubstrateInstalledCodeImpl

java.lang.Object

jdk.vm.ci.code.InstalledCode

com.oracle.svm.graal.meta.SubstrateInstalledCodeImpl

All Implemented Interfaces:

SubstrateInstalledCode

public class SubstrateInstalledCodeImpl
extends jdk.vm.ci.code.InstalledCode
implements SubstrateInstalledCode

Represents the installed code of a runtime compiled method. Note that Truffle uses its own implementation of SubstrateInstalledCode, so no code within Substrate VM must assume that this is the only representation of runtime compiled code. Metadata for the code is maintained by the class CodeInfo.

Method Detail

getMethod

public jdk.vm.ci.meta.ResolvedJavaMethod getMethod()

Description copied from interface: SubstrateInstalledCode

Returns the last method object passed to SubstrateInstalledCode.setAddress(long, jdk.vm.ci.meta.ResolvedJavaMethod). The return value might be passed as the argument to future calls to SubstrateInstalledCode.setAddress(long, jdk.vm.ci.meta.ResolvedJavaMethod).

May return null if the subclass does not have a use for the method object (also not in SubstrateInstalledCode.setAddress(long, jdk.vm.ci.meta.ResolvedJavaMethod)) and therefore no need to retain it. Expected to return null if SubstrateInstalledCode.setAddress(long, jdk.vm.ci.meta.ResolvedJavaMethod) has never been called, or after SubstrateInstalledCode.clearAddress() has been called.

Specified by:

getMethod in interface SubstrateInstalledCode

setAddress

public void setAddress(long address,
                       jdk.vm.ci.meta.ResolvedJavaMethod method)

Description copied from interface: SubstrateInstalledCode

Called during code installation: initialize this instance with the given address where its instructions are, and the method it was compiled from. Afterwards, SubstrateInstalledCode.getAddress() and SubstrateInstalledCode.getEntryPoint() return the given address, and SubstrateInstalledCode.isValid() and SubstrateInstalledCode.isAlive() return true.

Specified by:

setAddress in interface SubstrateInstalledCode

clearAddress

public void clearAddress()

Description copied from interface: SubstrateInstalledCode

This method is called during code uninstallation. Consider SubstrateInstalledCode.invalidate() instead.

Reset this instance so that SubstrateInstalledCode.getAddress() and SubstrateInstalledCode.getEntryPoint() return 0, and SubstrateInstalledCode.isValid() and SubstrateInstalledCode.isAlive() return false.

Specified by:

clearAddress in interface SubstrateInstalledCode

invalidate

public void invalidate()

Description copied from interface: SubstrateInstalledCode

Invalidates this installed code and deoptimizes all live invocations, after which both SubstrateInstalledCode.isValid() and SubstrateInstalledCode.isAlive() return false.

Specified by:

invalidate in interface SubstrateInstalledCode

Overrides:

invalidate in class jdk.vm.ci.code.InstalledCode

invalidateWithoutDeoptimization

public void invalidateWithoutDeoptimization()

Currently not supported. Existing code would need modifications to ensure that there cannot be a safepoint between a read of InstalledCode.entryPoint (such as, at the end of InstalledCode.getEntryPoint()), and the invocation of the entry point that was read.

Specified by:

invalidateWithoutDeoptimization in interface SubstrateInstalledCode

getSpeculationLog

public SubstrateSpeculationLog getSpeculationLog()

Specified by:

getSpeculationLog in interface SubstrateInstalledCode

setCompilationId

public void setCompilationId(org.graalvm.compiler.core.common.CompilationIdentifier id)

Description copied from interface: SubstrateInstalledCode

Sets the identifier of the compilation that resulted in this code, which can be used to provide additional information in SubstrateInstalledCode.getName().

Specified by:

setCompilationId in interface SubstrateInstalledCode

getStart

public long getStart()

Overrides:

getStart in class jdk.vm.ci.code.InstalledCode

getCode

public byte[] getCode()

Overrides:

getCode in class jdk.vm.ci.code.InstalledCode

executeVarargs

public Object executeVarargs(Object... args)

Overrides:

executeVarargs in class jdk.vm.ci.code.InstalledCode
