-<p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layer is Cygwin.

So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>.

 <p><strong>Note:</strong> Cygwin has a model of continuously updating all packages without any easy way to install or revert to a specific version of a package. This means that whenever you add or update a package in Cygwin, you might (inadvertently) update tools that are used by the JDK build process, and that can cause unexpected build problems.</p>

This <a href="http://iosdevelopertips.com/xcode/install-multiple-versions-of-xcode.html">blog page</a> has good suggestions on managing multiple Xcode versions. To use a specific version of Xcode, use <code>xcode-select -s</code> before running <code>configure</code>, or use <code>--with-toolchain-path</code> to point to the version of Xcode to use, e.g. <code>configure --with-toolchain-path=/Applications/Xcode8.app/Contents/Developer/usr/bin</code></p>
+<p>When updating Xcode, it is advisable to keep an older version for building the JDK. To use a specific version of Xcode you have multiple options:</p>
+<ul>
+<li>Use <code>xcode-select -s</code> before running <code>configure</code>, e.g. <code>xcode-select -s /Applications/Xcode13.1.app</code>. The drawback is that the setting is system wide and you may have to revert it after an OpenJDK build.</li>
+<li>Use configure option <code>--with-xcode-path</code>, e.g. <code>configure --with-xcode-path=/Applications/Xcode13.1.app</code> This allows using a specific Xcode version for an OpenJDK build, independently of the active Xcode version by <code>xcode-select</code>.</li>
+</ul>
 <p>If you have recently (inadvertently) updated your OS and/or Xcode version, and the JDK can no longer be built, please see the section on <a href="#problems-with-the-build-environment">Problems with the Build Environment</a>, and <a href="#getting-help">Getting Help</a> to find out if there are any recent, non-merged patches available for this update.</p>

+<h2 id="signing">Signing</h2>
+<h3 id="macos-1">macOS</h3>
+<p>Modern versions of macOS require applications to be signed and notarizied before distribution. See Apple's documentation for more background on what this means and how it works. To help support this, the JDK build can be configured to automatically sign all native binaries, and the JDK bundle, with all the options needed for successful notarization, as well as all the entitlements required by the JDK. To enable <code>hardened</code> signing, use configure parameter <code>--with-macosx-codesign=hardened</code> and configure the signing identity you wish to use with <code>--with-macosx-codesign-identity=&lt;identity&gt;</code>. The identity refers to a signing identity from Apple that needs to be preinstalled on the build host.</p>
+<p>When not signing for distribution with the hardened option, the JDK build will still attempt to perform <code>adhoc</code> signing to add the special entitlement <code>com.apple.security.get-task-allow</code> to each binary. This entitlement is required to be able to dump core files from a process. Note that adding this entitlement makes the build invalid for notarization, so it is only added when signing in <code>debug</code> mode. To explicitly enable this kind of adhoc signing, use configure parameter <code>--with-macosx-codesign=debug</code>. It will be enabled by default in most cases.</p>
+<p>It's also possible to completely disable any explicit codesign operations done by the JDK build using the configure parameter <code>--without-macosx-codesign</code>. The exact behavior then depends on the architecture. For macOS on x64, it (at least at the time of this writing) results in completely unsigned binaries that should still work fine for development and debugging purposes. On aarch64, the Xcode linker will apply a default &quot;adhoc&quot; signing, without any entitlements. Such a build does not allow dumping core files.</p>
+<p>The default mode &quot;auto&quot; will try for <code>hardened</code> signing if the debug level is <code>release</code> and either the default identity or the specified identity is valid. If hardened isn't possible, then <code>debug</code> signing is chosen if it works. If nothing works, the codesign build step is disabled.</p>
 <h2 id="cross-compiling">Cross-compiling</h2>
 <p>Cross-compiling means using one platform (the <em>build</em> platform) to generate output that can ran on another platform (the <em>target</em> platform).</p>
 <p>The typical reason for cross-compiling is that the build is performed on a more powerful desktop computer, but the resulting binaries will be able to run on a different, typically low-performing system. Most of the complications that arise when building for embedded is due to this separation of <em>build</em> and <em>target</em> systems.</p>
 <p>This requires a more complex setup and build procedure. This section assumes you are familiar with cross-compiling in general, and will only deal with the particularities of cross-compiling the JDK. If you are new to cross-compiling, please see the <a href="https://en.wikipedia.org/wiki/Cross_compiler#External_links">external links at Wikipedia</a> for a good start on reading materials.</p>
 <p>Cross-compiling the JDK requires you to be able to build both for the build platform and for the target platform. The reason for the former is that we need to build and execute tools during the build process, both native tools and Java tools.</p>
 <p>If all you want to do is to compile a 32-bit version, for the same OS, on a 64-bit machine, consider using <code>--with-target-bits=32</code> instead of doing a full-blown cross-compilation. (While this surely is possible, it's a lot more work and will take much longer to build.)</p>
+<h3 id="cross-compiling-the-easy-way-with-openjdk-devkits">Cross compiling the easy way with OpenJDK devkits</h3>
+<p>The OpenJDK build system provides out-of-the box support for creating and using so called devkits. A <code>devkit</code> is basically a collection of a cross-compiling toolchain and a sysroot environment which can easily be used together with the <code>--with-devkit</code> configure option to cross compile the OpenJDK. On Linux/x86_64, the following command:</p>
+<pre><code>bash configure --with-devkit=&lt;devkit-path&gt; --openjdk-target=ppc64-linux-gnu &amp;&amp; make</code></pre>
+<p>will configure and build OpenJDK for Linux/ppc64 assuming that <code>&lt;devkit-path&gt;</code> points to a Linux/x86_64 to Linux/ppc64 devkit.</p>
+<p>Devkits can be created from the <code>make/devkit</code> directory by executing:</p>
+<pre><code>make [ TARGETS=&quot;&lt;TARGET_TRIPLET&gt;+&quot; ] [ BASE_OS=&lt;OS&gt; ] [ BASE_OS_VERSION=&lt;VER&gt; ]</code></pre>
+<p>where <code>TARGETS</code> contains one or more <code>TARGET_TRIPLET</code>s of the form described in <a href="https://sourceware.org/autobook/autobook/autobook_17.html">section 3.4 of the GNU Autobook</a>. If no targets are given, a native toolchain for the current platform will be created. Currently, at least the following targets are known to work:</p>
+<table>

+</tbody>
+</table>
+<p><code>BASE_OS</code> must be one of &quot;OEL6&quot; for Oracle Enterprise Linux 6 or &quot;Fedora&quot; (if not specified &quot;OEL6&quot; will be the default). If the base OS is &quot;Fedora&quot; the corresponding Fedora release can be specified with the help of the <code>BASE_OS_VERSION</code> option (with &quot;27&quot; as default version). If the build is successful, the new devkits can be found in the <code>build/devkit/result</code> subdirectory:</p>
+<pre><code>cd make/devkit
+make TARGETS=&quot;ppc64le-linux-gnu aarch64-linux-gnu&quot; BASE_OS=Fedora BASE_OS_VERSION=21
+ls -1 ../../build/devkit/result/
+x86_64-linux-gnu-to-aarch64-linux-gnu
+x86_64-linux-gnu-to-ppc64le-linux-gnu</code></pre>
+<p>Notice that devkits are not only useful for targeting different build platforms. Because they contain the full build dependencies for a system (i.e. compiler and root file system), they can easily be used to build well-known, reliable and reproducible build environments. You can for example create and use a devkit with GCC 7.3 and a Fedora 12 sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't have GCC 7.3 by default) to produce OpenJDK binaries which will run on all Linux systems with runtime libraries newer than the ones from Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).</p>

 <h3 id="building-for-armaarch64">Building for ARM/aarch64</h3>
 <p>A common cross-compilation target is the ARM CPU. When building for ARM, it is useful to set the ABI profile. A number of pre-defined ABI profiles are available using <code>--with-abi-profile</code>: arm-vfp-sflt, arm-vfp-hflt, arm-sflt, armv5-vfp-sflt, armv6-vfp-hflt. Note that soft-float ABIs are no longer properly supported by the JDK.</p>
 <p>The JDK contains two different ports for the aarch64 platform, one is the original aarch64 port from the <a href="http://openjdk.java.net/projects/aarch64-port">AArch64 Port Project</a> and one is a 64-bit version of the Oracle contributed ARM port. When targeting aarch64, by the default the original aarch64 port is used. To select the Oracle ARM 64 port, use <code>--with-cpu-port=arm64</code>. Also set the corresponding value (<code>aarch64</code> or <code>arm64</code>) to --with-abi-profile, to ensure a consistent build.</p>

+still attempt to perform `adhoc` signing to add the special entitlement
+`com.apple.security.get-task-allow` to each binary. This entitlement is required
+to be able to dump core files from a process. Note that adding this entitlement
+makes the build invalid for notarization, so it is only added when signing in
+`debug` mode. To explicitly enable this kind of adhoc signing, use configure
+parameter `--with-macosx-codesign=debug`. It will be enabled by default in most
+cases.
+
+It's also possible to completely disable any explicit codesign operations done
+by the JDK build using the configure parameter `--without-macosx-codesign`.
+The exact behavior then depends on the architecture. For macOS on x64, it (at
+least at the time of this writing) results in completely unsigned binaries that
+should still work fine for development and debugging purposes. On aarch64, the
+Xcode linker will apply a default "adhoc" signing, without any entitlements.
+Such a build does not allow dumping core files.
+
+The default mode "auto" will try for `hardened` signing if the debug level is
+`release` and either the default identity or the specified identity is valid.
+If hardened isn't possible, then `debug` signing is chosen if it works. If
+nothing works, the codesign build step is disabled.
 
 ## Cross-compiling
 
@@ -875,6 +940,64 @@ If all you want to do is to compile a 32-bit version, for the same OS, on a
 full-blown cross-compilation. (While this surely is possible, it's a lot more
 work and will take much longer to build.)
 
+### Cross compiling the easy way with OpenJDK devkits
+
+The OpenJDK build system provides out-of-the box support for creating and using
+so called devkits. A `devkit` is basically a collection of a cross-compiling
+toolchain and a sysroot environment which can easily be used together with the
+`--with-devkit` configure option to cross compile the OpenJDK. On Linux/x86_64,
+the following command:
+```
+bash configure --with-devkit=<devkit-path> --openjdk-target=ppc64-linux-gnu && make
+```
+
+will configure and build OpenJDK for Linux/ppc64 assuming that `<devkit-path>`
+points to a Linux/x86_64 to Linux/ppc64 devkit.
+
+Devkits can be created from the `make/devkit` directory by executing:
+```
+make [ TARGETS="<TARGET_TRIPLET>+" ] [ BASE_OS=<OS> ] [ BASE_OS_VERSION=<VER> ]
+```
+
+where `TARGETS` contains one or more `TARGET_TRIPLET`s of the form
+described in [section 3.4 of the GNU Autobook](
+https://sourceware.org/autobook/autobook/autobook_17.html). If no
+targets are given, a native toolchain for the current platform will be
+created. Currently, at least the following targets are known to work:
+
+ Supported devkit targets
+ ------------------------
+ x86_64-linux-gnu
+ aarch64-linux-gnu
+ arm-linux-gnueabihf
+ ppc64-linux-gnu
+ ppc64le-linux-gnu
+ s390x-linux-gnu
+
+`BASE_OS` must be one of "OEL6" for Oracle Enterprise Linux 6 or
+"Fedora" (if not specified "OEL6" will be the default). If the base OS
+is "Fedora" the corresponding Fedora release can be specified with the
+help of the `BASE_OS_VERSION` option (with "27" as default version).
+If the build is successful, the new devkits can be found in the
+`build/devkit/result` subdirectory:
+```
+cd make/devkit
+make TARGETS="ppc64le-linux-gnu aarch64-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=21
+ls -1 ../../build/devkit/result/
+x86_64-linux-gnu-to-aarch64-linux-gnu
+x86_64-linux-gnu-to-ppc64le-linux-gnu
+```
+
+Notice that devkits are not only useful for targeting different build
+platforms. Because they contain the full build dependencies for a
+system (i.e. compiler and root file system), they can easily be used
+to build well-known, reliable and reproducible build environments. You
+can for example create and use a devkit with GCC 7.3 and a Fedora 12
+sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't
+have GCC 7.3 by default) to produce OpenJDK binaries which will run on
+all Linux systems with runtime libraries newer than the ones from
+Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).

+### Cross compiling with Debian sysroots
+
+Fortunately, you can create sysroots for foreign architectures with tools
+provided by your OS. On Debian/Ubuntu systems, one could use `qemu-deboostrap` to
+create the *target* system chroot, which would have the native libraries and headers
+specific to that *target* system. After that, we can use the cross-compiler on the *build*
+system, pointing into chroot to get the build dependencies right. This allows building
+for foreign architectures with native compilation speed.
+
+For example, cross-compiling to AArch64 from x86_64 could be done like this:
+
+  * Install cross-compiler on the *build* system:
+    ```
+    apt install g++-aarch64-linux-gnu gcc-aarch64-linux-gnu
+    ```
+
+  * Create chroot on the *build* system, configuring it for *target* system:
+    ```
+    sudo qemu-debootstrap \
+      --arch=arm64 \
+      --verbose \
+      --include=fakeroot,symlinks,build-essential,libx11-dev,libxext-dev,libxrender-dev,libxrandr-dev,libxtst-dev,libxt-dev,libcups2-dev,libfontconfig1-dev,libasound2-dev,libfreetype6-dev,libpng-dev,libffi-dev \
+      --resolve-deps \
+      buster \
+      ~/sysroot-arm64 \
+      http://httpredir.debian.org/debian/
+    ```
+
+  * Make sure the symlinks inside the newly created chroot point to proper locations:
+    ```
+    sudo chroot ~/sysroot-arm64 symlinks -cr .
+    ```
+
+  * Configure and build with newly created chroot as sysroot/toolchain-path:
+    ```
+    sh ./configure \
+      --openjdk-target=aarch64-linux-gnu \
+      --with-sysroot=~/sysroot-arm64
+    make images
+    ls build/linux-aarch64-normal-server-release/
+    ```
+
+The build does not create new files in that chroot, so it can be reused for multiple builds
+without additional cleanup.
+
+The build system should automatically detect the toolchain paths and dependencies, but sometimes
+it might require a little nudge with:
+
+  * Native compilers: override `CC` or `CXX` for `./configure`
+
+  * Freetype lib location: override `--with-freetype-lib`, for example `${sysroot}/usr/lib/${target}/`
+
+  * Freetype includes location: override `--with-freetype-include` for example `${sysroot}/usr/include/freetype2/`
+
+  * X11 libraries location: override `--x-libraries`, for example `${sysroot}/usr/lib/${target}/`

-proper push path for pushing changes to the JDK.

-Here's one way to do this:
-
-```
-cd ~
-mkdir hg-ext
-cd hg-ext
-hg clone http://hg.openjdk.java.net/code-tools/defpath
-cat << EOT >> ~/.hgrc
-[extensions]
-defpath=~/hg-ext/defpath/defpath.py
-EOT
-```
-
-You can now setup a proper push path using:
-```
-hg defpath -d -u <your OpenJDK username>
-```
-
-If you also have the `trees` extension installed in Mercurial, you will
-automatically get a `tdefpath` command, which is even more useful. By running
-`hg tdefpath -du <username>` in the top repository of your forest, all repos
-will get setup automatically. This is the recommended usage.

+### Common Test Groups
+
+Ideally, all tests are run for every change but this may not be practical due to the limited
+testing resources, the scope of the change, etc.
+
+The source tree currently defines a few common test groups in the relevant `TEST.groups`
+files. There are test groups that cover a specific component, for example `hotspot_gc`.
+It is a good idea to look into `TEST.groups` files to get a sense what tests are relevant
+to a particular JDK component.
+
+Component-specific tests may miss some unintended consequences of a change, so other
+tests should also be run. Again, it might be impractical to run all tests, and therefore
+_tiered_ test groups exist. Tiered test groups are not component-specific, but rather cover
+the significant parts of the entire JDK.
+
+Multiple tiers allow balancing test coverage and testing costs. Lower test tiers are supposed to
+contain the simpler, quicker and more stable tests. Higher tiers are supposed to contain
+progressively more thorough, slower, and sometimes less stable tests, or the tests that require
+special configuration.
+
+Contributors are expected to run the tests for the areas that are changed, and the first N tiers
+they can afford to run, but at least tier1.
+
+A brief description of the tiered test groups:
+
+- `tier1`: This is the lowest test tier. Multiple developers run these tests every day.
+Because of the widespread use, the tests in `tier1` are carefully selected and optimized to run
+fast, and to run in the most stable manner. The test failures in `tier1` are usually followed up
+on quickly, either with fixes, or adding relevant tests to problem list. GitHub Actions workflows,
+if enabled, run `tier1` tests.
+
+- `tier2`: This test group covers even more ground. These contain, among other things,
+tests that either run for too long to be at `tier1`, or may require special configuration,
+or tests that are less stable, or cover the broader range of non-core JVM and JDK features/components
+(for example, XML).
+
+- `tier3`: This test group includes more stressful tests, the tests for corner cases
+not covered by previous tiers, plus the tests that require GUIs. As such, this suite
+should either be run with low concurrency (`TEST_JOBS=1`), or without headful tests
+(`JTREG_KEYWORDS=\!headful`), or both.
+
+- `tier4`: This test group includes every other test not covered by previous tiers. It includes,
+for example, `vmTestbase` suites for Hotspot, which run for many hours even on large
+machines. It also runs GUI tests, so the same `TEST_JOBS` and `JTREG_KEYWORDS` caveats
+apply.
