Abstract: Dynamic trace sizing for tracing just-in-time compilation is provided. A trace of a program is generated during a tracing phase of the just-in-time compilation. The trace of the program is profiled to determine an estimated effective trace size prior to compiling the trace. Additional profiling is performed to determine a garbage collection time and consequently a total execution time of the program based on the estimated effective trace size determined prior to compiling the trace. It is determined whether to continue formation of the trace or trigger termination of the trace based on the garbage collection time of the program. Triggering the termination of the trace dynamically sizes the trace at runtime of the program.

Abstract: Approaches presented herein enable providing online method handle deduplication by determining whether a method handle to be created is equivalent to an existing method handle in an equivalence pool. Specifically, in response to a request to create a method handle, a set of parameters including a method handle map, a class, and one or more arguments of the method handle to be created are accepted. A method handle of the class is obtained. One or more existing unique method handles found in an equivalence pool are compared to the method handle to be created to determine whether an equivalence exists. When an equivalence is found between an existing unique method handle and the method handle to be created, the existing unique method handle is returned.
