Method Detail

addMethod

InstalledCode addMethod(ResolvedJavaMethod method,
                        CompilationResult compResult,
                        SpeculationLog speculationLog,
                        InstalledCode predefinedInstalledCode)

Adds the given compilation result as an implementation of the given method without making it the default implementation.

Parameters:

method - a method to which the executable code is begin added

compResult - the compilation result to be added

speculationLog - the speculation log to be used

Returns:

a reference to the compiled and ready-to-run code or throws a BailoutException if the code installation failed

setDefaultMethod

InstalledCode setDefaultMethod(ResolvedJavaMethod method,
                               CompilationResult compResult)

Sets the given compilation result as the default implementation of the given method.

Parameters:

method - a method to which the executable code is begin added

compResult - the compilation result to be added

Returns:

a reference to the compiled and ready-to-run code or null if the code installation failed

getMarkName

default String getMarkName(CompilationResult.Mark mark)

Gets a name for a CompilationResult.Mark mark.

getTargetName

default String getTargetName(CompilationResult.Call call)

Gets a name for the target of a CompilationResult.Call.

getRegisterConfig

RegisterConfig getRegisterConfig()

Gets the register configuration to use when compiling a given method.

getMinimumOutgoingSize

int getMinimumOutgoingSize()

Minimum size of the stack area reserved for outgoing parameters. This area is reserved in all cases, even when the compiled method has no regular call instructions.

Returns:

the minimum size of the outgoing parameter area in bytes

needsDataPatch

boolean needsDataPatch(JavaConstant constant)

Determines if a CompilationResult.DataPatch should be created for a given primitive constant that is part of a CompilationResult. A data patch is always created for an object constant.

createDataItem

DataSection.Data createDataItem(Constant constant)

Create a DataSection.Data item for a Constant, that can be used in a CompilationResult.DataPatch.

getTarget

TargetDescription getTarget()

Gets a description of the target architecture.

createSpeculationLog

SpeculationLog createSpeculationLog()

Create a new speculation log for the target runtime.
