 # This is a helper script to evaluate nashorn with optimistic types

 # it produces a flight recording for every run, and uses the best 

 # known flags for performance for the current configration

 ###########################################################################################

 # Flags to instrument lambdaform computation, caching, interpretation and compilation

 # Default compile threshold for lambdaforms is 30

 #FLAGS="-Djava.lang.invoke.MethodHandle.COMPILE_THRESHOLD=3 -Djava.lang.invoke.MethodHandle.DUMP_CLASS_FILES=true -Djava.lang.invoke.MethodHandle.TRACE_METHOD_LINKAGE=true -Djava.lang.invoke.MethodHandle.TRACE_INTERPRETER=true"

 # Flags to run trusted tests from the Nashorn test suite

 #FLAGS="-Djava.security.manager -Djava.security.policy=../build/nashorn.policy -Dnashorn.debug"

 # Unique timestamped file name for JFR recordings. For JFR, we also have to

 # crank up the stack cutoff depth to 1024, because of ridiculously long lambda form

 # stack traces.

 #

 # It is also recommended that you go into $JAVA_HOME/jre/lib/jfr/default.jfc and

 # set the "method-sampling-interval" Normal and Maximum sample time as low as you

 # can go (10 ms on most platforms). The default is normally higher. The increased

 # sampling overhead is usually negligible for Nashorn runs, but the data is better

 # that we run the script from the make dir

 # Type specialization and math intrinsic replacement should be enabled by default in 8u20 and nine,
