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).

     2 OPENJDK ASSEMBLY EXCEPTION

     4 The OpenJDK source code made available by Sun at openjdk.java.net and

     5 openjdk.dev.java.net ("OpenJDK Code") is distributed under the terms of the

     6 GNU General Public License <http://www.gnu.org/copyleft/gpl.html> version 2

     7 only ("GPL2"), with the following clarification and special exception.

     9     Linking this OpenJDK Code statically or dynamically with other code

    10     is making a combined work based on this library.  Thus, the terms

    11     and conditions of GPL2 cover the whole combination.

    13     As a special exception, Sun gives you permission to link this

    14     OpenJDK Code with certain code licensed by Sun as indicated at

    15     http://openjdk.java.net/legal/exception-modules-2007-05-08.html

    16     ("Designated Exception Modules") to produce an executable,

    17     regardless of the license terms of the Designated Exception Modules,

    18     and to copy and distribute the resulting executable under GPL2,

    19     provided that the Designated Exception Modules continue to be

    20     governed by the licenses under which they were offered by Sun.

    22 As such, it allows licensees and sublicensees of Sun's GPL2 OpenJDK Code to

    23 build an executable that includes those portions of necessary code that Sun

    24 could not provide under GPL2 (or that Sun has provided under GPL2 with the

    25 Classpath exception).  If you modify or add to the OpenJDK code, that new

    26 GPL2 code may still be combined with Designated Exception Modules if the

    27 new code is made subject to this exception by its copyright holder.
