Method Detail

getTextSection

public com.oracle.objectfile.ObjectFile.Section getTextSection()

Description copied from class: AbstractBootImage

Returns the ObjectFile.Section within the image, if any, whose vaddr defines the image's base vaddr.

Specified by:

getTextSection in class AbstractBootImage

makeLaunchCommand

public abstract String[] makeLaunchCommand(AbstractBootImage.NativeImageKind k,

                                           Method method)

Specified by:

makeLaunchCommand in class AbstractBootImage

write

protected final void write(Path outputFile)

build

public void build(org.graalvm.compiler.debug.DebugContext debug)

Create the image sections for code, constants, and the heap.

Specified by:

build in class AbstractBootImage

localSymbolNameForMethod

public static String localSymbolNameForMethod(Method m)

Given a java.lang.reflect.Method, compute the symbol name of its start address (if any) in the image. The symbol name returned is the one that would be used for local references (e.g. for relocation), so is guaranteed to exist if the method is in the image. However, it is not necessarily visible for linking from other objects.

Parameters:

m - a java.lang.reflect.Method

Returns:

its symbol name as it would appear in the image (regardless of whether it actually does)

localSymbolNameForMethod

public static String localSymbolNameForMethod(jdk.vm.ci.meta.ResolvedJavaMethod sm)

Given a ResolvedJavaMethod, compute what symbol name of its start address (if any) in the image. The symbol name returned is the one that would be used for local references (e.g. for relocation), so is guaranteed to exist if the method is in the image. However, it is not necessarily visible for linking from other objects.

Parameters:

sm - a SubstrateMethod

Returns:

its symbol name as it would appear in the image (regardless of whether it actually does)

globalSymbolNameForMethod

public static String globalSymbolNameForMethod(Method m)

Given a java.lang.reflect.Method, compute the symbol name of its entry point (if any) in the image. The symbol name returned is one that would be used for external references (e.g. for linking) and for method lookup by signature. If multiple methods with the same signature are present in the image, the returned symbol name is not guaranteed to resolve to the method being passed.

Parameters:

m - a java.lang.reflect.Method

Returns:

its symbol name as it would appear in the image (regardless of whether it actually does)

globalSymbolNameForMethod

public static String globalSymbolNameForMethod(jdk.vm.ci.meta.ResolvedJavaMethod sm)

Given a ResolvedJavaMethod, compute what symbol name of its entry point (if any) in the image. The symbol name returned is one that would be used for external references (e.g. for linking) and for method lookup by signature. If multiple methods with the same signature are present in the image, the returned symbol name is not guaranteed to resolve to the method being passed.

Parameters:

sm - a SubstrateMethod

Returns:

its symbol name as it would appear in the image (regardless of whether it actually does)

getOrCreateDebugObjectFile

public com.oracle.objectfile.ObjectFile getOrCreateDebugObjectFile()

Specified by:

getOrCreateDebugObjectFile in class AbstractBootImage
