Patch for building Java8 JDK repository
by Jonathan Lu 13 Dec '12

13 Dec '12

Hello, I've got a patch to build Java8 JDK repository [1] on AIX 64 and Linux PPC 64, and plan to push it to [1], before that I'd like to get some comments here :) The patch includes two parts, I) Patches ported from PPC Java7u repository [3], which includes various changes from 'corba' and 'jdk' repositories. II) Several small new changes to make the compilation pass. http://cr.openjdk.java.net/~luchsh/ppc-port-bringup-java8/ Since the HotSpot patches have not yet been ported to Java8, so I was using OpenJDK7 builds [2] provided by Volker as bootstrapping JDK and use JDK7 HotSpot as alternative import. So in part II) patch there's a workaround for non-existing VM interface. Many thanks - Jonathan [1] http://hg.openjdk.java.net/ppc-aix-port/jdk8/jdk [2] http://cr.openjdk.java.net/~simonis/ppc-aix-port/bootstrap/ [3] http://hg.openjdk.java.net/ppc-aix-port/jdk7u

hg: ppc-aix-port/jdk7u/hotspot: opto / regalloc: Fix problem with rematerialization
by goetz.lindenmaier＠sap.com 12 Dec '12

Changeset: 79eae7bb8433 Author: Goetz Date: 2012-12-12 16:56 +0100 URL: http://hg.openjdk.java.net/ppc-aix-port/jdk7u/hotspot/rev/79eae7bb8433 opto / regalloc: Fix problem with rematerialization On PPC, castX2P is rematerialized just where the live range of another rematerialized node using the same def lives. This causes invalid register dependencies (while the code happens to be correct). In the end the VM aborts with assert(!_reg_node[reg_lo] || edge_from_to(_reg_node[reg_lo],def), msg); Seen in jvm2008: -Xcomp -Xbatch -Djava.io.tmpdir=./tmp -jar SPECjvm2008.jar -ikv -wt 30 -it 60 -bt 2 --base xml.validation in sun.awt.X11.XAtom::getAtomListProperty. Fixed by aborting and retrying the register allocation cycle. We had to increase the number of register allocation cycles, as as consequence we got spill split recycle failures. This fix is suboptimal as it increases the runtime of the register allocation (only on PPC), but we saw similar problems in various situations. Therefor excluding castX2P from rematerialization not only worsens register allocation, but is not sufficient, either. ! src/share/vm/opto/chaitin.cpp ! src/share/vm/opto/reg_split.cpp
