#  Generate the reorder data for hotspot.
#
#  Usage:
#
#	sh  reorder.sh  <test_sdk_workspace>  <test_sdk>  <jbb_dir>
#
#	<test_sdk_workspace> is a *built* SDK workspace which contains the
#	reordering tools for the SDK.  This script relies on lib_mcount.so
#	from this workspace.
#
#	<test_sdk> is a working SDK which you can use to run the profiled
#	JVMs in to collect data.  You must be able to write to this SDK.
#
#	<jbb_dir> is a directory containing JBB test jar files and properties
#	which will be used to run the JBB test to provide reordering data
#	for the server VM.
#
#	Profiled builds of the VM are needed (before running this script),
#	build with PROFILE_PRODUCT=1:
#
#		gnumake profiled1 profiled PROFILE_PRODUCT=1
