Class InvokeeThreadLocalContext

java.lang.Object

org.jikesrvm.compilers.opt.specialization.InvokeeThreadLocalContext

All Implemented Interfaces:

SpecializationContext

public final class InvokeeThreadLocalContext
extends Object
implements SpecializationContext

This class represents a specialization context meaning "the invokee is thread local". We use this context to remove unnecessary synchronizations.

Method Detail

findOrCreateSpecializedVersion

public SpecializedMethod findOrCreateSpecializedVersion(NormalMethod source)

Description copied from interface: SpecializationContext

Finds or creates a specialized version of source for this context. Do NOT compile it immediately. However, DO allocate an spmd if needed.

Specified by:

findOrCreateSpecializedVersion in interface SpecializationContext

Parameters:

source - the method that needs a specialized version

Returns:

the created specialized method

createSpecializedMethod

private SpecializedMethod createSpecializedMethod(NormalMethod method)

specialCompile

public CompiledMethod specialCompile(NormalMethod source)

Generate code to specialize a method in this context. Namely, invoke the opt compiler with the INVOKEE_THREAD_LOCAL option.

Specified by:

specialCompile in interface SpecializationContext

Parameters:

source - the method to compile

Returns:

the compiled method associated with the specialized method version

init

public static void init()

Initialize static members.
