Method Detail

singleton

public static CGlobalDataFeature singleton()

duringSetup

public void duringSetup(org.graalvm.nativeimage.hosted.Feature.DuringSetupAccess access)

Specified by:

duringSetup in interface org.graalvm.nativeimage.hosted.Feature

afterHeapLayout

public void afterHeapLayout(org.graalvm.nativeimage.hosted.Feature.AfterHeapLayoutAccess access)

Specified by:

afterHeapLayout in interface org.graalvm.nativeimage.hosted.Feature

registerInvocationPlugins

public void registerInvocationPlugins(org.graalvm.compiler.phases.util.Providers providers,
                                      org.graalvm.compiler.api.replacements.SnippetReflectionProvider snippetReflection,
                                      org.graalvm.compiler.nodes.graphbuilderconf.GraphBuilderConfiguration.Plugins plugins,
                                      ParsingReason reason)

Description copied from interface: GraalFeature

Called to register Graal invocation plugins.

Specified by:

registerInvocationPlugins in interface GraalFeature

Parameters:

providers - Providers that the lowering can use.

snippetReflection - Snippet reflection providers.

plugins - Contains the invocation plugins to add to.

reason - The parsing phase that the plugins are registered for

registerAsAccessedOrGet

public CGlobalDataInfo registerAsAccessedOrGet(CGlobalData<?> obj)

registerWithGlobalSymbol

public void registerWithGlobalSymbol(CGlobalData<?> obj)

Makes the provided object available in the binary as a global symbol Warning: Global symbols are affected by linking and loading rules that are OS dependent. So accessing a global symbol content at run time using the symbol name could return a different content than the one provided at build time. This happens for example on Linux when a shared library is loaded and the main executable already defines a symbol with the same name.

registerWithGlobalHiddenSymbol

public void registerWithGlobalHiddenSymbol(CGlobalData<?> obj)

Same as CGlobalDataFeature.registerWithGlobalSymbol(CGlobalData) but hides the provided object so that it will not show up in the dynamic symbol table of the final image.

getGlobalHiddenSymbols

public Set<String> getGlobalHiddenSymbols()

getSize

public int getSize()

writeData

public void writeData(RelocatableBuffer buffer,
                      CGlobalDataFeature.SymbolConsumer createSymbol,
                      CGlobalDataFeature.SymbolConsumer createSymbolReference)
