#  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
