Abstract
Integrated trace selection and profiling in dynamic optimizers may include selecting a trace head based on profile of basic blocks that are executed. The basic blocks executed from the trace head may be recorded as a trace. The trace may be added to a trace nursery in non-compiled state. The trace may be interpreted and profiled until the trace matures. Under a profiling mode, path sensitive runtime information such as values, types, targets of call-sites, and exit frequencies can be collected. The trace may be moved out of the nursery to a compilation queue in response to determining that the trace has matured based on an execution count of the profiled trace.
