Hi,
Various changes to documentation, config and test excludes
- Documentation changes
I have updated the documentation as it was getting rather out of date (eg referring to C2 being incomplete, wrong links etc etc).
Also corrected spelling of README-Xcompile-aarc64.html.orig to README-Xcompile-aarch64.html
(the 'h' key is dodgy on my laptop which is why this was misspelled in the first place - there is something ironic about an Irishman with a busted 'h' key)
- Configure changes
I have removed the --with-boot-jdk and the --with-cacerts-file arguments to configure in the cross_configure script. The OE build no longer builds a native JVM in the sysroots so these were pointing to non existent locations with the latest sysroots.
The --with-cacerts-file argument was broken in any case as it meant that the build was picking up the cacerts from the native OpenJDK7 in the sysroots rather than using the one from the OpenJDK8 sources.
For --with-boot-jdk the build will pick up the default java on the host.
I have also changed the default build type from fastdebug,client to release,server as I feel that this is more in keeping with the state of the project and I wish to remove the possibility of people accidentally doing benchmarking on the wrong build.
- Test changes
Added a test to the exclude which is also failing on x86. Bug reported against JDK 1.8.0 and also JDK 7u51.
OK to push?
Ed.

-<h2>Cross compile build for aarch64</h2>
-<p>This page describes the steps necessary to perform a cros compile build
-for aarch64 and how to run the resultant images under the Foundation model
-(ARM's freely available aarc64 simulator).
-
-</p><p>The steps basically comprise the following
-
-</p><dl>
-<dt>Step 1</dt><dd><a href="#Sysroots">Obtain an aarch64 sysroots</a><br>
-</dd><dt>Step 2</dt><dd><a href="#BuildOpenJDK">Configure and compile OpenJDK</a>

-</dd><dt>Step 6</dt><dd><a href="#BootModel">Boot the Foundation model and run your OpenJDK image</a>
-</dd></dl>
-
-<h3><a name="Sysroots"></a>Step 1: Obtain an aarch64 sysroots</h3>
-
-<p>The sysroots directory contains all the cross compilation tools, aarch64
-libraries and headers you will need to perform a cross compile build of
-OpenJDK for aarch64.
-
-</p><p>For convenience I have provided a pre-built sysroots at
-<a href="http://people.linaro.org/%7Eedward.nevill/aarch64/sysroots.tar.gz">
-http://people.linaro.org/~edward.nevill/aarch64/sysroots.tar.gz</a>
-
-</p><p>Note that the above sysroots will only work if you are building on a 64-bit
-x86 linux machine. If you are using anything else you will need to rebuild
-the sysroots as the cross compilation tools will not work on your macine.
-
-</p><p>Download the sysroots.tar.gz file above and untar it into the directory containing the jdk8 repository so that the <b>jdk8</b> directory and <b>sysroots</b> directory are at the same level.
-
-</p><pre><code><b>
-cd <directory containing jdk8>
-tar xfz sysroots.tar.gz
-ls
-</b>
-jdk8 sysroots sysroots.tar.gz
-</code></pre>
-
-<h3><a name="BuildOpenJDK"></a>Step 2: Configure and compile OpenJDK</h3>
-
-<p>Two shell scripts have been provided to allow you to quickstart building OpenJDK.
-
-</p><dl>
-<dt>cross_configure</dt><dd>Configure for a cross compiled release build of OpenJDK
-</dd><dt>cross_compile</dt><dd>Build the j2re and j2sdk images for the current configuration
-</dd></dl>
-
-<p>In theory all that should be necessary is
-
-</p><pre><code><b>
-cd jdk8
-sh ./cross_configure
-sh ./cross_compile 2>&1 | tee compile.log
-</b></code></pre>
-
-<p>This should build a client compiler (C1) release version of OpenJDK which may be found in <i>build/linux-aarch64-normal-client-release/images/j2sdk-image</i>
-
-</p><p>Note: At the end of the build you may see an warning like
-
-</p><pre>WARNING: You have the following ALT_ variables set:
-ALT_SDT_H=/home/ed/work/aa64/sysroots/genericarmv8/usr/include/sys/sdt.h
-ALT_ variables are deprecated and will be ignored. Please clean your environment.
-</pre>
-
-<p>This warning may be ignored. The ALT_SDT_H <b>is</b> required and is not ignored!
-
-</p><h4>Changing build/config options</h4>
-
-<p>To build a debug version edit the <i>cross_configure</i> file and change <b>--with-debug-level=release</b>
-to one of <b>--with-debug-level=fastdebug</b> or <b>--with-debug-level=slowdebug</b>
-
-</p><p>To build a Zero release change <b>--with-jvm-variants=client</b> to <b>--with-jvm-variants=zero</b>. You can
-also specify <b>--with-jvm-variants=server</b>, however the server (C2) compiler is still under development
-at the time of writing.
-
-</p><p>If you specify a new configuration such as <b>--with-debug-level=slowdebug</b> you may get the following
-error when you run the <i>cross_compile</i> script.
-
-</p><pre>No CONF given, but more than one configuration found in /home/ed/work/aarch64_tip/jdk8//build.
-Available configurations:
-* linux-aarch64-normal-client-slowdebug
-* linux-aarch64-normal-client-release
-Please retry building with CONF=<config pattern=""> (or SPEC=<specfile>)
-</specfile></config></pre>
-
-<p>To select which configuation you wish to build specify CONF=... before the <i>cross_compile</i> script. For example:
-
-</p><pre><code><b>
-CONF=linux-aarch64-normal-client-slowdebug sh ./cross_compile 2>&1 | tee compile.log
-</b></code></pre>
-
-<p>Some other useful options you can specify to configure are:
-
-</p><dl>
-<dt>--enable-debug-symbols</dt><dt>--disable-debug-symbols
-</dt><dd>Enable/disable generation of debug symbols
-</dd><dt>--enable-zip-debug-info</dt><dt>--disable-zip-debug-info
-</dt><dd>Enable/disable zipping of debug-info files
-</dd></dl>
-
-<h3><a name="GetModel"></a>Step 3: Download the Foundation model</h3>
-
-Download the foundation model from ARM's website at
-
-<a href="http://www.arm.com/products/tools/models/fast-models/foundation-model.php">
-http://www.arm.com/products/tools/models/fast-models/foundation-model.php
-</a>
-
-<p>At the bottom of the page under <i>Get started with Foundation Models</i>
-click on <i>download now</i>. You will be asked to login. If you have
-prevously registered for an ARM account login, otherwise you will need
-to check the license terms, ensure that you are happy with them and
-register for an ARM account.
-
-</p><p>After logging in above, on the right hand side of the next page under
-<i>ARM V8 Foundation Model</i> click <i>Download Now</i>.
-
-</p><p>The name of the file I downloaded was <i>FM000-KT-00035-r0p8-48rel5.tgz</i>.
-Obviously the name of the file you download may differ depending on the
-version number you download, but if you want to download exactly the
-same version number you can look for it under "Display older versions".
-
-</p><p>Untar this archive. It will create a directory 'Foundation_v8pkg'. cd to
-this directory
-
-</p><pre><code><b>
-tar xfz FM000-KT-00035-r0p8-48rel5.tgz
-cd Foundation_v8pkg
-</b></code></pre>
-
-<h3><a name="RootFS"></a>Step 4: Download a kernel and root filesystem</h3>
-
-<p>For convenience I have provided a pre-built kernel and pre-populated rootfs at
-
-</p><ul>
-<li><a href="http://people.linaro.org/%7Eedward.nevill/aarch64/kernel.axf">
-http://people.linaro.org/~edward.nevill/aarch64/kernel.axf</a>

-http://people.linaro.org/~edward.nevill/aarch64/rootfs.ext2.gz</a>
-</li></ul>
-
-<p>Download both these files into the <i>Foundation_v8pkg</i> directory created above
-and decompress the <i>rootfs.ext2.gz</i>
-
-</p><pre><code><b>
-gzip -d rootfs.ext2.gz
-</b></code></pre>
-
-<h3><a name="CopyOpenJDK"></a>Step 5: Copy your OpenJDK image into your rootfs</h3>
-
-<p>First of all you must mount the root file system. Then copy the OpenJDK image into
-the home directory of root. Then unmount the filesystem.
-
-</p><pre><code><b>
-sudo mount -o loop rootfs.ext2 /mnt
-sudo cp -r .../jdk8/build/linux-aarch64-normal-client-release/images/j2sdk-image /mnt/home/root
-sudo umount /mnt
-</b></code></pre>
-
-<h3><a name="BootModel"></a>Step 6: Boot the Foundation model and run OpenJDK</h3>
-
-<p>To boot the Foundation model enter
-
-</p><pre><code><b>
-./models/Linux64_GCC-4.1/Foundation_v8 --image kernel.axf --block-device rootfs.ext2 --network nat
-</b></code></pre>
-
-<p>An xterm window will open and Linux will boot in the aarch64 simulator. After a short
-while you will get the root '#' prompt. In the root directory you should find the
-<i>j2sdk-image</i> directory you copied earlier in addition to a <i>JavaApps</i> directory
-which contains some sample Java applications.
-
-</p><pre><code><b>
-ls</b>
-JavaApps j2sdk-image
-</code></pre>
-
-
-
-<p>The following are brief instructions on running each of the provided sample applications.
-In each case you can specify the following options.
-
-</p><dl>

Overview
--------
-The current AArch64 port of OpenJDK allows execution of a template
-interpreter implemented using JITted AArch64 code and a C1 JIT
-compiler which generates AArch64 code. It does not yet include a
-complete implementation of the C2 JIT compiler.
+The AArch64 port of OpenJDK provides C1 (Client) JIT, C2 (Server)
+JIT support and Template Interpreter support for AArch64.
