All Implemented Interfaces:

PhaseSizeContract

public class InstrumentTruffleBoundariesPhase
extends InstrumentPhase

Instruments calls to TruffleBoundary-annotated methods in the graph, by adding execution counters to respective callsites. If this phase is enabled, the runtime outputs a summary of all such compiled callsites and their execution counts, when the program exits. The phase is enabled with the following flag:

 -Dgraal.TruffleInstrumentBoundaries
 

The phase can be configured to only instrument callsites in specific methods, by providing the following method filter flag:

 -Dgraal.TruffleInstrumentBoundariesFilter
 

The flag:

 -Dgraal.TruffleInstrumentBoundariesPerInlineSite
 

decides whether to treat different inlining sites separately when tracking the execution counts.
