Constructor Detail

HotSpotReplacementsImpl

public HotSpotReplacementsImpl(HotSpotProviders providers,
                               SnippetReflectionProvider snippetReflection,
                               BytecodeProvider bytecodeProvider,
                               TargetDescription target)

Method Detail

getProviders

public HotSpotProviders getProviders()

Specified by:

getProviders in interface Replacements

Overrides:

getProviders in class ReplacementsImpl

maybeInitializeEncoder

public void maybeInitializeEncoder()

getIntrinsifyingPlugin

public Class<? extends GraphBuilderPlugin> getIntrinsifyingPlugin(ResolvedJavaMethod method)

Description copied from interface: Replacements

Gets the plugin type that intrinsifies calls to method.

Specified by:

getIntrinsifyingPlugin in interface Replacements

Overrides:

getIntrinsifyingPlugin in class ReplacementsImpl

registerConditionalPlugin

public void registerConditionalPlugin(InvocationPlugin plugin)

Description copied from interface: Replacements

Marks a plugin as conditionally applied. In the contenxt of libgraal conditional plugins can't be used in during graph encoding for snippets and method substitutions and this is used to detect violations of this restriction.

Specified by:

registerConditionalPlugin in interface Replacements

Overrides:

registerConditionalPlugin in class ReplacementsImpl

notifyNotInlined

public void notifyNotInlined(GraphBuilderContext b,
                             ResolvedJavaMethod method,
                             Invoke invoke)

Description copied from interface: InlineInvokePlugin

Notifies this plugin of the Invoke node created for a method that was not inlined per InlineInvokePlugin.shouldInlineInvoke(org.graalvm.compiler.nodes.graphbuilderconf.GraphBuilderContext, ResolvedJavaMethod, org.graalvm.compiler.nodes.ValueNode[]).

Specified by:

notifyNotInlined in interface InlineInvokePlugin

Overrides:

notifyNotInlined in class ReplacementsImpl

Parameters:

b - the context

method - the method that was not inlined

invoke - the invoke node created for the call to method

registerSnippet

public void registerSnippet(ResolvedJavaMethod method,
                            ResolvedJavaMethod original,
                            Object receiver,
                            boolean trackNodeSourcePosition,
                            OptionValues options)

Description copied from interface: Replacements

Registers a method as snippet.

Specified by:

registerSnippet in interface Replacements

Overrides:

registerSnippet in class ReplacementsImpl

getSnippetParameterInfo

public SnippetParameterInfo getSnippetParameterInfo(ResolvedJavaMethod method)

Description copied from interface: Replacements

Get the snippet metadata required to inline the snippet.

Specified by:

getSnippetParameterInfo in interface Replacements

Overrides:

isSnippet

public boolean isSnippet(ResolvedJavaMethod method)

Description copied from interface: Replacements

Return true if the method is a Snippet.

Specified by:

isSnippet in interface Replacements

Overrides:

isSnippet in class ReplacementsImpl

closeSnippetRegistration

public void closeSnippetRegistration()

Description copied from interface: Replacements

Notifies this method that no further snippets will be registered via Replacements.registerSnippet(ResolvedJavaMethod, ResolvedJavaMethod, java.lang.Object, boolean, org.graalvm.compiler.options.OptionValues) or Replacements.registerSnippetTemplateCache(org.graalvm.compiler.api.replacements.SnippetTemplateCache). This is a hook for an implementation to check for or forbid late registration.
