Field Detail

gcMapNanos

private static long gcMapNanos

osrSetupNanos

private static long osrSetupNanos

codeGenNanos

private static long codeGenNanos

encodingNanos

private static long encodingNanos

options

public static BaselineOptions options
Options used during base compiler execution

edgeCounterIdx

protected int edgeCounterIdx
Next edge counter entry to allocate

localTypes

protected final byte[] localTypes
The types that locals can take. There are two types of locals. First the parameters of the method, they only have one type Second, the other locals, numbers get reused when stack shrinks and grows again. Therefore, these can have more than one type assigned. The compiler can use this information to assign registers to locals See the BaselineCompilerImpl constructor.

Constructor Detail

BaselineCompiler

protected BaselineCompiler(BaselineCompiledMethod cm)
Construct a BaselineCompilerImpl

Method Detail

getEdgeCounterOffset

protected final Offset getEdgeCounterOffset()

getEdgeCounterIndex

protected final int getEdgeCounterIndex()

initOptions

public static void initOptions()
Clear out crud from bootimage writing

fullyBootedVM

public static void fullyBootedVM()
Now that VM is fully booted, enable options such as PRINT_MACHINE_CODE that require a fully booted VM.

processCommandLineArg

public static void processCommandLineArg(String prefix,
                                         String arg)
Process a command line argument

Parameters:
prefix -
arg - Command line argument with prefix stripped off

generateBaselineCompilerSubsystemReport

public static void generateBaselineCompilerSubsystemReport(boolean explain)
Generate a report of time spent in various phases of the baseline compiler.

NB: This method may be called in a context where classloading and/or GC cannot be allowed. Therefore we must use primitive sysWrites for output and avoid string appends and other allocations.

Parameters:
explain - Should an explanation of the metrics be generated?

compile

public static CompiledMethod compile(NormalMethod method)
Compile the given method with the baseline compiler.

Parameters:
method - the NormalMethod to compile.
Returns:
the generated CompiledMethod for said NormalMethod.

initializeCompiler

protected abstract void initializeCompiler()

compile

protected void compile()
Top level driver for baseline compilation of a method.

getCompilerName

protected String getCompilerName()
Specified by:
getCompilerName in class TemplateCompilerFramework
