6906727: UseCompressedOops: some card-marking fixes related to object arrays
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). Reviewed-by: kvn, coleenp, jmasa
README: This file should be located at the top of the OpenJDK Mercurial repository forest. This top or enclosing repository will include a "make" directory, and a Makefile at the very top of the repository. It should also include the 6 repositories: "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". See http://openjdk.java.net/ for more information about the OpenJDK. Simple Build Instructions: 1. Download and install a JDK 6 from http://java.sun.com/javase/downloads/index.jsp Set the environment variable ALT_BOOTDIR to the location of this JDK 6. 2. Download and install the Binary Plugs for the most recent JDK7 from http://download.java.net/openjdk/jdk7/ Set the environment variable ALT_BINARY_PLUGS_PATH to the location of these binary plugs. 3. Check the sanity of doing a build with the current machine: gnumake sanity See README-builds.html if you run into problems. 4. Do a complete build of the jdk: gnumake all The resulting JDK image should be found in build/*/j2sdk-image where gnumake is GNU make 3.78.1 or newer, /usr/bin/make on Linux and /usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
