6906727: UseCompressedOops: some card-marking fixes related to object arrays
Summary: Introduced a new write_ref_array(HeapWords* start, size_t count) method that does the requisite MemRegion range calculation so (some of the) clients of the erstwhile write_ref_array(MemRegion mr) do not need to worry. This removed all external uses of array_size(), which was also simplified and made private. Asserts were added to catch other possible issues. Further, less essential, fixes stemming from this investigation are deferred to CR 6904516 (to follow shortly in hs17).

duke@435 2 OPENJDK ASSEMBLY EXCEPTION
duke@435 3
duke@435 4 The OpenJDK source code made available by Sun at openjdk.java.net and
duke@435 5 openjdk.dev.java.net ("OpenJDK Code") is distributed under the terms of the
duke@435 6 GNU General Public License <http://www.gnu.org/copyleft/gpl.html> version 2
duke@435 7 only ("GPL2"), with the following clarification and special exception.
duke@435 8
duke@435 9 Linking this OpenJDK Code statically or dynamically with other code
duke@435 10 is making a combined work based on this library. Thus, the terms
duke@435 11 and conditions of GPL2 cover the whole combination.
duke@435 12
duke@435 13 As a special exception, Sun gives you permission to link this
duke@435 14 OpenJDK Code with certain code licensed by Sun as indicated at
duke@435 15 http://openjdk.java.net/legal/exception-modules-2007-05-08.html
duke@435 16 ("Designated Exception Modules") to produce an executable,
duke@435 17 regardless of the license terms of the Designated Exception Modules,
duke@435 18 and to copy and distribute the resulting executable under GPL2,
duke@435 19 provided that the Designated Exception Modules continue to be
duke@435 20 governed by the licenses under which they were offered by Sun.
duke@435 21
duke@435 22 As such, it allows licensees and sublicensees of Sun's GPL2 OpenJDK Code to
duke@435 23 build an executable that includes those portions of necessary code that Sun
duke@435 24 could not provide under GPL2 (or that Sun has provided under GPL2 with the
duke@435 25 Classpath exception). If you modify or add to the OpenJDK code, that new
duke@435 26 GPL2 code may still be combined with Designated Exception Modules if the
duke@435 27 new code is made subject to this exception by its copyright holder.
