+
+## Release Flavours
+
+There are many kinds of JBR bundles available on the [Releases page](https://github.com/JetBrains/JetBrainsRuntime/releases):
+
+| Flavour       | Description                                                                                                   |
+|---------------|---------------------------------------------------------------------------------------------------------------|
+| JBR           | Contains the Java Runtime Environment (JRE) suitable to _run_ JVM-based programs.                             |
+| JBRSDK        | Contains the Software Developmet Kit (SDK) suitable to _develop_ and _run_ JVM-based programs.                |
+| JBR with JCEF | Contains both JBR and JCEF; this flavour is bundled by default with all IntelliJ IDEs.                        |
+| vanilla       | Contains just JBR.                                                                                            |
+| fastdebug     | The native binaries in this bundle are less optimized and are easier to debug. They also run much slower.     |
+| FreeType      | The bundle includes the freetype library built from sources; normally, the library is provided by the system. |
+| Vulkan        | The bundle includes experimental Vulkan support.                                                              |                                                              |
+| debug symbols | In addition to the usual contents of the bundle the debug information is also included.                       |

+
+## Why Use JetBrains Runtime?
+* **Embedded browser**: JetBrains Runtime includes the Java Chromium Embedded Framework ([JCEF](https://github.com/JetBrains/jcef)), which
+  enables you to embed a Chromium-based browsers in your JVM-based application.
+ To use it, [download a build with JCEF](https://github.com/JetBrains/JetBrainsRuntime/releases).
+* **Enhanced class re-definition** with the [DCEVM](https://ssw.jku.at/dcevm/) technology that makes it easier to reload
+  changed code without restarting JVM; this feature needs to be explicitly enabled with `-XX:+AllowEnhancedClassRedefinition`.
+* **Better FPS performance** for graphics-intensive applications.
+* **Improved font rendering**, **keyboard input** (such as shortcuts and multinational keyboards),
+  **HiDPI** and **accessibility** support.
+* **Robust desktop experience**: GUI-related fixes often reach JetBrains Runtime much earlier than the corresponding version of OpenJDK.
+* Additional capabilities that are made available to applications through
+  [JBR API](https://github.com/JetBrains/JetBrainsRuntimeApi) services such as, for example, 
+  the ability to wrap a native graphics texture into `java.awt.Image`.

+
+## Getting Sources
+### macOS, Linux
+```
+git config --global core.autocrlf input
+git clone git@github.com:JetBrains/JetBrainsRuntime.git
+```
+
+### Windows
+<a name="sources-windows"></a>
+```
+git config --global core.autocrlf false
+git clone git@github.com:JetBrains/JetBrainsRuntime.git
+```
+
+## Configuring the Build Environment
+Here are quick per-platform instructions for those who can't wait to get started.
+Please refer to [OpenJDK build docs](https://openjdk.java.net/groups/build/doc/building.html) for in-depth
+coverage of all the details.
+
+> **_TIP:_**  To get a preliminary report of what's missing, run `./configure` and check its output.
+> It would usually have meaningful advice on how to solve the problem.
+
+### Linux (Docker)
+Download an image from [Docker Hub](https://hub.docker.com/repository/docker/jetbrains/runtime/general) related to your architecture:
+```
+$ docker pull jetbrains/runtime:oraclelinux8_aarch64
+```
+or
+```
+$ docker pull jetbrains/runtime:oraclelinux8_x64
+```
+Create and run a new container from the downloaded image
+```
+$ docker run -v $JetBrainsRuntime:/JetBrainsRuntime -it jetbrains/runtime:oraclelinux8_[arch]
+```
+where `$JetBrainsRuntime` is a full path to the directory where the repository was cloned to.
+
+Run these commands in the container:
+```
+# cd /JetBrainsRuntime
+# sh ./configure
+# make images
+```
+
+### Ubuntu Linux
+Install the necessary tools, libraries, and headers with:
+```
+$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
+       libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev libspeechd-dev libwayland-dev \
+       wayland-protocols libxkbcommon-x11-0 libdbus-1-dev
+```
+Get Java 23 (for instance, [Azul Zulu Builds of OpenJDK 23](https://www.azul.com/downloads/?version=java-23&os=linux&package=jdk#zulu)).
+
+Then run the following:
+```
+$ cd JetBrainsRuntime
+$ git checkout main
+$ sh ./configure
+$ make images
+```
+This will build the release configuration under `./build/linux-x86_64-server-release/`.
+
+### Windows
+<a name="build-windows"></a>
+Install the following:
+* [Cygwin x64](http://www.cygwin.com/).
+  Required packages: `autoconf`, `binutils`, `cpio`, `diffutils`, `file`, `gawk`, `gcc-core`, `make`, `m4`, `unzip`, `zip`.
+  Install those together with Cygwin.
+* [Visual Studio compiler toolset](https://visualstudio.microsoft.com/downloads/).
+  Install with the desktop development kit, which includes Windows SDK and compilers.
+  Visual Studio 2019 is supported by default.
+* Java 21 (for instance, [Azul Zulu Builds of OpenJDK 21](https://www.azul.com/downloads/?version=java-21-lts&os=windows&package=jdk#zulu)).
+  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).
+
+From the command line:
+```
+"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
+"c:\Program_Files\cygwin64\bin\mintty.exe" /bin/bash -l
+```
+The first command sets up environment variables, the second starts a Cygwin shell with the proper environment.
+
+In the Cygwin shell:
+```
+$ cd JetBrainsRuntime
+$ git checkout main
+$ bash configure --with-toolchain-version=2019
+$ make images
+```
+This will build the release configuration under `./build/windows-x86_64-server-release/`.
+
+#### Enable optional NVDA screen reader support
+If you want to add support of a11y announcing via [NVDA screen reader](https://www.nvaccess.org/about-nvda/),
+you will need to bundle the NVDA Controller Client library.
+You can do it with the following steps:
+1. Download the NVDA Controller Client library. You can find the link in its official README [here](https://github.com/nvaccess/nvda/blob/master/extras/controllerClient/readme.md)
+2. Pass the path to the unpacked package to `configure` via an additional flag `--with-nvdacontrollerclient=<path>`.
+   The build system will search the required library files under `<path>/<target-arch>`.
+
+#### Disable optional JAWS screen reader support
+JBR is built with built-in support of JAWS screen reader.
+If you want to disable it, run `configure` with the additional flag `--disable-jaws-client`.
+
+### macOS
+Install the following:
+* Xcode command line developer tools and `autoconf` via [Homebrew](https://brew.sh/).
+* Java 21 (for instance, [Azul Zulu Builds of OpenJDK 21](https://www.azul.com/downloads/?version=java-21-lts&os=macos&package=jdk#zulu)).
+
+From the command line:
+```
+$ cd JetBrainsRuntime
+$ git checkout main
+$ sh ./configure
+$ make images
+```
+This will build the release configuration under `./build/macosx-x86_64-server-release/`.
+
+## Developing
+You can use  [CLion](https://www.jetbrains.com/clion/) to develop native parts of the JetBrains Runtime and
+[IntelliJ IDEA](https://www.jetbrains.com/idea/) for the parts written in Java.
+Both require projects to be created.
+
+### CLion
+Run
+```
+$ make compile-commands
+```
+in the git root and open the resulting `build/.../compile_commands.json` file as a project.
+Then use `Tools | Compilation Database | Change Project Root` to point to git root of this repository.
+
+See also this detailed step-by-step tutorial for all platforms:
+[How to develop OpenJDK with CLion](https://blog.jetbrains.com/clion/2020/03/openjdk-with-clion/).
+
+### IDEA
+Run
+```
+$ sh ./bin/idea.sh
+```
+in the git root to generate project files (add `--help` for options). If you have multiple
+configurations (for example, `release` and `fastdebug`), supply the `--conf <conf_name>` argument.
+Then open the git root directory as a project in IDEA.

+is a compiler optimization used to avoid potentially expensive copies in
+certain situations. It is critical to making practical the performance
+of return by value or pass by value. It is also unusual in not following
+the as-if rule for optimizations - copy elision can be applied even if
+doing so bypasses side-effects of copying/moving the object. The C++
+standard explicitly permits this.</p>
+<p>However, because it's an optional optimization, the relevant
+copy/move constructor must be available and accessible, in case the
+compiler chooses to not apply the optimization even in a situation where
+permitted.</p>
+<p>C++17 changed some cases of copy elision so that there is never a
+copy/move in these cases (<a
+href="http://wg21.link/p0135r1">p0135r1</a>). The interesting cases
+involve a function that returns an unnamed temporary object, and
+constructors. In such cases the object being initialized from the
+temporary is always direct initialized, with no copy/move ever involved;
+see <a href="https://en.wikipedia.org/wiki/Copy_elision#RVO"
+title="Return Value Optimization">RVO</a> and more specifically <a
+href="https://cn.cppreference.com/w/cpp/language/copy_elision.html"
+title="Unnamed Return Value Optimization">URVO</a>.</p>
+<p>Since this is now standard behavior it can't be avoided in the
+covered situations. This could change the behavior of code that relied
+on side effects by constructors, but that's both uncommon and was
+already problematic because of the previous optional copy elision. But
+HotSpot code can, and should, explicitly take advantage of this newly
+required behavior where it makes sense to do so.</p>
+<p>For example, it may be beneficial to delay construction of the result
+of a function until the return statement, rather than having a local
+variable that is modified into the desired state and then returned.
+(Though <a href="https://en.wikipedia.org/wiki/Copy_elision#NRVO"

+<p>HotSpot is built with exceptions disabled, e.g. compile with
+<code>-fno-exceptions</code> (gcc, clang) or no <code>/EH</code> option
+(MSVC++). So why do we need to consider <code>noexcept</code> at all?
+It's because <code>noexcept</code> exception specifications serve two
+distinct purposes.</p>
+<p>The first is to allow the compiler to avoid generating code or data
+in support of exceptions being thrown by a function. But this is
+unnecessary, because exceptions are disabled.</p>
+<p>The second is to allow the compiler and library code to choose
+different algorithms, depending on whether some function may throw
+exceptions. This is only relevant to a certain set of functions.</p>
+<ul>
+<li><p>Some allocation functions (<code>operator new</code> and
+<code>operator new[]</code>) return <code>nullptr</code> to indicate
+allocation failure. If a <code>new</code> expression calls such an
+allocation function, it must check for and handle that possibility.
+Declaring such a function <code>noexcept</code> informs the compiler
+that <code>nullptr</code> is a possible result. If an allocation
+function is not declared <code>noexcept</code> then the compiler may
+elide that checking and handling for a <code>new</code> expression
+calling that function.</p></li>
+<li><p>Certain Standard Library facilities (notably containers) provide
+different guarantees for some operations (and may choose different
+algorithms to implement those operations), depending on whether certain
+functions (constructors, copy/move operations, swap) are nothrow or not.
+They detect this using type traits that test whether a function is
+declared <code>noexcept</code>. This can have a significant performance
+impact if, for example, copying is chosen over a potentially throwing
+move. But this isn't relevant, since HotSpot forbids the use of most
+Standard Library facilities.</p></li>
+</ul>
+<p>HotSpot code can assume no exceptions will ever be thrown, even from

+<p>The primary purpose of this change seems to be to make certain kinds

 <p>This list is incomplete; it serves to explicitly call out some

+<p>Some Standard Library features are undecided (so implicitly

+<code>assert</code> incompatibility, incompatibility with HotSpot's
+<code>FORBID_C_FUNCTION</code> mechanism, and the like.</p>

+<p>It is undecided whether to permit the use of
+<code>std::optional&lt;&gt;</code> (<a
+href="http://wg21.link/p0220r1">p0220r1</a>). It may be sufficiently
+useful that it should be permitted despite the usual prohibition against
+using Standard Library facilities. Use of the <code>value()</code>
+member function must be forbidden, as it reports an invalid access by
+throwing an exception.</p>
+<h3 id="stdbyte">std::byte</h3>
+<p>It is undecided whether to permit the use of the
+<code>std::byte</code> type (<a

+useful that it should be permitted despite the usual prohibition against
+using Standard Library facilities.</p>
+<p>It has been suggested that changing the HotSpot <code>address</code>

+replace</p>
+<pre><code>typedef u_char*       address;

+<pre><code>using address       = std::byte*;
+using const_address = const std::byte*;</code></pre>
+<p>in globalDefinitions.hpp.</p>
+<p>A specific benefit that was mentioned is that it might improve the
+horrible way that gdb handles our current definition of the
+<code>address</code> type.</p>
+<pre><code>#include &lt;cstddef&gt;
+
+typedef unsigned char* address;
+typedef std::byte* address_b;
+

+<p>It is undecided whether to permit the use of
+<code>std::string_view</code> (<a
+href="http://wg21.link/p0220r1">p0220r1</a>).</p>
+<p>HotSpot doesn't use <code>std::string</code>, but uses
+<code>char*</code> strings a lot. Wrapping such in a
+<code>std::string_view</code> to enable the use of various algorithms
+could be useful. But since HotSpot also doesn't permit use of
+<code>&lt;algorithm&gt;</code> and the like, that only gets the limited
+set of algorithms provided by the view class directly.</p>
+<p>There is also the issue of <code>NUL</code> termination; string views
+are not necessarily <code>NUL</code> terminated. Moreover, if one goes
+to the work of making one that is <code>NUL</code> terminated, that
+terminator is included in the size.</p>
+<p>There are other caveats. Permitting use of string views would require
+discussion of those.</p>
+<h3 id="substring-and-subsequence-searching">Substring and Subsequence
+Searching</h3>
+<p>In addition to simple substring searching, the Standard Library now
+includes Boyer-Moore and Boyer-Moore-Horspool searchers, in case someone
+wants to search really large texts. That seems an unlikely use-case for
+HotSpot. See <a href="http://wg21.link/p0220r1">p0220r1</a>.</p>
+<h3 id="new-and-delete-with-over-aligned-data"><code>new</code> and
+<code>delete</code> with Over-Aligned Data</h3>
+<p>It is undecided whether to permit the use of dynamic allocation of
+overaligned types (<a href="http://wg21.link/n3396">n3396</a>).</p>
+<p>HotSpot currently only has a couple of over-aligned types that are
+dynamically allocated. These are handled manually, not going through
+<code>new</code> expressions, as that couldn't work before C++17.</p>
+<p>One of the ways an over-aligned type might arise is by aligning a
+data member. This might be done to avoid destructive interference for
+concurrent accesses. But HotSpot uses a different approach, using
+explicit padding. Again, this is in part because <code>new</code> and
+<code>delete</code> of overaligned types didn't work. But we might
+prefer to continue this approach.</p>
+<p>We would need to add <code>operator new</code> overloads to
+<code>CHeapObj&lt;&gt;</code> and possibly in other places in order to
+support this. However, it has been suggested that implementing it
+(efficiently) on top of NMT might be difficult. Note that
+<code>posix_memalign</code> / <code>_aligned_malloc</code> don't help
+here, because of NMT's use of malloc headers.</p>
+<p>If we don't support it we may want to add <code>operator new</code>
+overloads that are deleted, to prevent attempted uses.</p>
+<p>Alignment usage in non-HotSpot parts of the OpenJDK:</p>
+<ul>

+<code>std::to_chars()</code> and <code>std::from_chars()</code> (<a
+href="http://wg21.link/p0067r5">p0067r5</a>).</p>
+<p>These functions provide low-level conversions between character
+sequences and numeric values. This seems like a good candidate for use
+in HotSpot, potentially replacing various clumsy or less performant
+alternatives. There is no memory allocation. Parsing failures are
+indicated via error codes rather than exceptions. Various other nice for
+HotSpot properties.</p>
+<p>Note that the published C++17 Standard puts these in
+<code>&lt;utility&gt;</code>, but a defect report moved them to
+<code>&lt;charconv&gt;</code>. This also needs
+<code>&lt;system_error&gt;</code>.</p>
+<p>This would require upgrading the minimum gcc version to 11.1 for
+floating point conversion support. The minimum Visual Studio version is
+already sufficient. The minimum clang version requirement hasn't been
+determined yet.</p>

+### Trailing return type syntax for functions
+
+A function's return type may be specified after the parameters and qualifiers
+([n2541](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2541.htm)).
+In such a declaration the normal return type is `auto` and the return type is
+indicated by `->` followed by the type.  Although both use `auto` in the
+"normal" leading return type position, this differs from
+[function return type deduction](#function-return-type-deduction),
+in that the return type is explicit rather than deduced, but specified in a
+trailing position.
+
+Use of trailing return types is permitted.  However, the normal, leading
+position for the return type is preferred. A trailing return type should only
+be used where it provides some benefit. Such benefits usually arise because a
+trailing return type is in a different scope than a leading return type.
+
+* If the function identifier is a nested name specifier, then the trailing
+return type occurs in the nested scope. This may permit simpler naming in the
+return type because of the different name lookup context.
+
+* The trailing return type is in the scope of the parameters, making their
+types accessible via `decltype`. For example
+```
+template<typename T, typename U> auto add(T t, U u) -> decltype(t + u);
+```
+rather than
+```
+template<typename T, typename U> decltype((*(T*)0) + (*(U*)0)) add(T t, U u);
+```
+
+* Complex calculated leading return types may obscure the normal syntactic
+boundaries, making it more difficult for a reader to find the function name and
+parameters. This is particularly common in cases where the return type is
+being used for [SFINAE]. A trailing return type may be preferable in such
+situations.

+C++17 extended the arguments permitted for non-type template parameters

+### Variable Templates and Inline Variables
+
+The use of variable templates (including static data member templates)
+([N3651](https://wg21.link/N3651)) is permitted. They provide parameterized
+variables and constants in a simple and direct form, instead of requiring the
+use of various workarounds.
+
+Variables with static storage duration and variable templates may be declared
+`inline` ([p0386r2](https://wg21.link/p0386r2)), and this usage is
+permitted. This has similar effects as for declaring a function inline: it can
+be defined, identically, in multiple translation units, must be defined in
+every translation unit in which it is [ODR used][ODR], and the behavior of the
+program is as if there is exactly one variable.
+
+Declaring a variable inline allows the complete definition to be in a header
+file, rather than having a declaration in a header and the definition in a
+.cpp file. The guidance on
+[initialization](#initializing-variables-with-static-storage-duration) of such
+variables still applies. Inline variables with dynamic initializations can
+make initialization order problems worse. The few ordering constraints
+that exist for non-inline variables don't apply, as there isn't a single
+program-designated translation unit containing the definition.
+
+A `constexpr` static data member or static data member template
+is implicitly `inline`. As a consequence, an
+[ODR use][ODR] of such a member doesn't require a definition in some .cpp
+file. (This is a change from pre-C++17. Beginning with C++17, such a
+definition is considered a duplicate definition, and is deprecated.)

+destructors at exit can lead to problems.
+
+Some of the approaches used in HotSpot to avoid dynamic initialization

+function at an appropriate place during VM initialization. The underlying

+
+[Copy elision](https://en.wikipedia.org/wiki/Copy_elision)
+(or [here](https://cn.cppreference.com/w/cpp/language/copy_elision.html))
+is a compiler optimization used to avoid potentially expensive copies in
+certain situations. It is critical to making practical the performance of
+return by value or pass by value. It is also unusual in not following the
+as-if rule for optimizations - copy elision can be applied even if doing so
+bypasses side-effects of copying/moving the object. The C++ standard
+explicitly permits this.
+
+However, because it's an optional optimization, the relevant copy/move
+constructor must be available and accessible, in case the compiler chooses to
+not apply the optimization even in a situation where permitted.
+
+C++17 changed some cases of copy elision so that there is never a copy/move in
+these cases ([p0135r1](http://wg21.link/p0135r1)). The interesting cases
+involve a function that returns an unnamed temporary object, and constructors.
+In such cases the object being initialized from the temporary is always direct
+initialized, with no copy/move ever involved; see [RVO] and more specifically
+[URVO].
+
+Since this is now standard behavior it can't be avoided in the covered
+situations. This could change the behavior of code that relied on side effects
+by constructors, but that's both uncommon and was already problematic because
+of the previous optional copy elision. But HotSpot code can, and should,
+explicitly take advantage of this newly required behavior where it makes sense
+to do so.
+
+For example, it may be beneficial to delay construction of the result of a
+function until the return statement, rather than having a local variable that
+is modified into the desired state and then returned. (Though [NRVO] may apply
+in that case.)
+
+It is also now possible to define a factory function for a class that is
+neither movable nor copyable, if it can be written in a way that makes use of
+this feature.

 list.
 
+[p0068r0](http://wg21.link/p0068r0) is the initial proposal for the attributes
+added by C++17.)
+
 Only the following attributes are permitted:
 
 * `[[noreturn]]`
+* `[[nodiscard]]` ([p0189r1](http://wg21.link/p0189r1))
+* `[[maybe_unused]]` ([p0212r1](http://wg21.link/p0212r1))

 * `[[carries_dependency]]` - Related to `memory_order_consume`.
 * `[[deprecated]]` - Not relevant in HotSpot code.
 
+Direct use of non-standard (and presumably scoped) attributes in shared code
+is also forbidden. Using such would depend on the C++17 feature that an
+attribute not recognized by the implementation is ignored
+([p0283r2](http://wg21.link/p0283r2)). If such an attribute is needed in
+shared code, the well-established technique of providing an `ATTRIBUTE_XXX`
+macro with per-compiler definitions (sometimes empty) should be
+used. Compilers may warn about unrecognized attributes (whether by name or by
+location), in order to report typos or misuse. Disabling such warnings
+globally would not be desirable.
+
+The use of `using` directives in attribute lists is also forbidden.
+([p0028r0](http://wg21.link/p0028r0))
+([p0028r4](http://wg21.link/p0028r4))
+We don't generally use scoped attributes in attribute lists with other
+attributes. Rather, uses of scoped attributes (which are implementation
+defined) are generally hidden behind a portability macro that includes the
+surrounding brackets.
+
+### noexcept
+
+Use of `noexcept` exception specifications
+([n3050](http://wg21.link/n3050))
+are permitted with restrictions described below.
+
+* Only the argument-less form of `noexcept` exception specifications are
+permitted.
+* Allocation functions that may return `nullptr` to indicate allocation
+failure must be declared `noexcept`.
+* All other uses of `noexcept` exception specifications are forbidden.
+* `noexcept` expressions are forbidden.
+* Dynamic exception specifications are forbidden.
+
+HotSpot is built with exceptions disabled, e.g. compile with `-fno-exceptions`
+(gcc, clang) or no `/EH` option (MSVC++). So why do we need to consider
+`noexcept` at all? It's because `noexcept` exception specifications serve two
+distinct purposes.
+
+The first is to allow the compiler to avoid generating code or data in support
+of exceptions being thrown by a function. But this is unnecessary, because
+exceptions are disabled.
+
+The second is to allow the compiler and library code to choose different
+algorithms, depending on whether some function may throw exceptions. This is
+only relevant to a certain set of functions.
+
+* Some allocation functions (`operator new` and `operator new[]`) return
+`nullptr` to indicate allocation failure. If a `new` expression calls such an
+allocation function, it must check for and handle that possibility. Declaring
+such a function `noexcept` informs the compiler that `nullptr` is a possible
+result. If an allocation function is not declared `noexcept` then the compiler
+may elide that checking and handling for a `new` expression calling that
+function.
+
+* Certain Standard Library facilities (notably containers) provide different
+guarantees for some operations (and may choose different algorithms to
+implement those operations), depending on whether certain functions
+(constructors, copy/move operations, swap) are nothrow or not. They detect
+this using type traits that test whether a function is declared `noexcept`.
+This can have a significant performance impact if, for example, copying is
+chosen over a potentially throwing move. But this isn't relevant, since
+HotSpot forbids the use of most Standard Library facilities.
+
+HotSpot code can assume no exceptions will ever be thrown, even from functions
+not declared `noexcept`. So HotSpot code doesn't ever need to check, either
+with conditional exception specifications or with `noexcept` expressions.
+
+The exception specification is part of the type of a function
+([p0012r1](http://wg21.link/p0012r1). This likely has little impact on HotSpot
+code, since the use of `noexcept` is expected to be rare.
+
+Dynamic exception specifications were deprecated in C++11. C++17 removed all
+but `throw()`, with that remaining a deprecated equivalent to `noexcept`.
+
+### Enhanced selection statements
+
+C++17 modified the _condition_ part of `if` and `switch` statements, permitting
+an _init-statement_ to be included
+([p0305r1](http://wg21.link/p0305r1)).
+
+Use of this feature is permitted. (However, complex uses may interfere with
+readability.) Limiting the scope of a variable involved in the condition,
+while also making the value available to the statement's body, can improve
+readability. The alternative method of scope-limiting by introducing a nested
+scope isn't very popular and is rarely used.
+
+This new syntax is in addition to the _condition_ being a declaration with a
+_brace-or-equal-initializer_. For an `if` statement this new sytax gains that
+benefit without violating the long-standing guidance against using
+[implicit conversions to `bool`](#avoid-implicit-conversions-to-bool),
+which still stands.
+
+For example, uses of Unified Logging sometimes explicitly check whether a
+`LogTarget` is enabled.  Instead of
+```
+  LogTarget(...) lt;
+  if (lt.is_enabled()) {
+    LogStream log(lt);
+    ... use log ...
+  }
+  ... lt is accessible but probably not needed here ...
+```
+using this feature one could write
+```
+  if (LogTarget(...) lt; lt.is_enabled()) {
+    LogStream log(lt);
+    ... use log ...
+  }
+```
+
+C++17 also added compile-time `if` statements
+([p0292r2](http://wg21.link/p0292r2)). Use of `if constexpr` is
+permitted. This feature can replace and (sometimes vastly) simplify many uses
+of [SFINAE]. The same declaration and initialization guidance for the
+_condition_ part apply here as for ordinary `if` statements.
+
+### Expression Evaluation Order
+
+C++17 tightened up the evaluation order for some kinds of subexpressions
+([p0138r2](http://wg21.link/p0138r2)). Note, however, that the Alternate
+Evaluation Order for Function Calls alternative in that paper was adopted,
+rather than the strict left to right order of evaluation for function call
+arguments that was proposed in the main body of the paper.
+
+The primary purpose of this change seems to be to make certain kinds of call
+chaining well defined. That's not a style widely used in HotSpot. In general
+it is better to continue to avoid questions in this area by isolating
+operations with side effects from other statements. In particular, continue to
+avoid modifying a value in an expression where it is also used.
+
+### Compatibility with C11
+
+C++17 refers to C11 rather than C99. This means that C11 libraries and
+functions may be used in HotSpot. There may be limitations because of
+differing levels of compatibility among various compilers and versions of
+those compilers.
+
+Note that the C parts of the JDK have been built with C11 selected for some
+time ([JDK-8292008](https://bugs.openjdk.org/browse/JDK-8292008)).

+
+### Structured Bindings
+
+The use of structured bindings [p0217r3](http://wg21.link/p0217r3) is
+forbidden.  Preferred approaches for handling functions with multiple return
+values include
+
+* Return a named class/struct intended for that purpose, with named and typed
+members/accessors.
+
+* Return a value along with out parameters (usually pointers, sometimes
+references).
+
+* Designate a sentinel "failure" value in the normal return value type, with
+some out of band location for additional information.  For example, this is
+the model typically used with `errno`, where a function returns a normal
+result, or -1 to indicate an error, with additional error information in
+`errno`.
+
+There is a strong preference for names and explicit types, as opposed to
+offsets and implicit types. For example, there are folks who strongly dislike
+that some of the Standard Library functions return `std::pair` because `first`
+and `second` members don't carry any useful information.
+
+### File System Library
+
+The use of the File System library is forbidden. HotSpot doesn't do very much
+with files, and already has adequate mechanisms for its needs. Rewriting in
+terms of this new library doesn't provide any obviously significant
+benefits. Having a mix of the existing usage and uses of this new library
+would be confusing.

 This list is incomplete; it serves to explicitly call out some
 features that have not yet been discussed.

-([n2541](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2541.htm))
+Some features are undecided (so implicitly forbidden) because we don't expect
+to use them at all. This might be reconsidered if someone finds a good use
+case.
 
-* Variable templates
-([n3651](https://isocpp.org/files/papers/N3651.pdf))
+Some Standard Library features are undecided (so implicitly forbidden)
+because, while this Style Guide forbids the use of such, they may be
+sufficiently useful that we want to permit them anyway. Doing so may require
+some idiomatic mechanism for addressing things like `assert` incompatibility,
+incompatibility with HotSpot's `FORBID_C_FUNCTION` mechanism, and the like.
+
+### std::optional<>
+
+It is undecided whether to permit the use of `std::optional<>`
+([p0220r1](http://wg21.link/p0220r1)). It may be sufficiently useful that it
+should be permitted despite the usual prohibition against using Standard
+Library facilities. Use of the `value()` member function must be forbidden, as
+it reports an invalid access by throwing an exception.
+
+### std::byte
+
+It is undecided whether to permit the use of the `std::byte` type
+([p0298r3](http://wg21.link/p0298r3)). It may be sufficiently useful that it
+should be permitted despite the usual prohibition against using Standard
+Library facilities.
+
+It has been suggested that changing the HotSpot `address` type to use
+`std::byte` has some benefits. That is, replace
+```
+typedef u_char*       address;
+typedef const u_char* const_address;
+```
+```
+using address       = std::byte*;
+using const_address = const std::byte*;
+```
+in globalDefinitions.hpp.
+
+A specific benefit that was mentioned is that it might improve the horrible
+way that gdb handles our current definition of the `address` type.
+```
+#include <cstddef>
+
+typedef unsigned char* address;
+typedef std::byte* address_b;
+
+int main() {
+
+  char* mem;
+
+  address addr = (address)mem;
+  address_b addr_b = (address_b)mem;
+
+  return 0;
+}
+```
+
+```
+(gdb) p addr
+$1 = (address) 0x7ffff7fe4fa0 <dl_main> "\363\017\036\372Uf\017\357\300H\211\345AWI\211\377AVAUATSH\201\354\210\002"
+(gdb) p addr_b
+$2 = (address_b) 0x7ffff7fe4fa0 <dl_main>
+```
+
+This needs to be explored. Some folks have said they will do so.
+
+### String Views
+
+It is undecided whether to permit the use of `std::string_view`
+([p0220r1](http://wg21.link/p0220r1)).
+
+HotSpot doesn't use `std::string`, but uses `char*` strings a lot. Wrapping
+such in a `std::string_view` to enable the use of various algorithms could be
+useful. But since HotSpot also doesn't permit use of `<algorithm>` and the
+like, that only gets the limited set of algorithms provided by the view class
+directly.
+
+There is also the issue of `NUL` termination; string views are not necessarily
+`NUL` terminated. Moreover, if one goes to the work of making one that is
+`NUL` terminated, that terminator is included in the size.
+
+There are other caveats. Permitting use of string views would require
+discussion of those.
+
+### Substring and Subsequence Searching
+
+In addition to simple substring searching, the Standard Library now includes
+Boyer-Moore and Boyer-Moore-Horspool searchers, in case someone wants to
+search really large texts. That seems an unlikely use-case for HotSpot.  See
+[p0220r1](http://wg21.link/p0220r1).
+
+### `new` and `delete` with Over-Aligned Data
+
+It is undecided whether to permit the use of dynamic allocation of overaligned
+types ([n3396](http://wg21.link/n3396)).
+
+HotSpot currently only has a couple of over-aligned types that are dynamically
+allocated. These are handled manually, not going through `new` expressions, as
+that couldn't work before C++17.
+
+One of the ways an over-aligned type might arise is by aligning a data member.
+This might be done to avoid destructive interference for concurrent accesses.
+But HotSpot uses a different approach, using explicit padding. Again, this is
+in part because `new` and `delete` of overaligned types didn't work. But we
+might prefer to continue this approach.
+
+We would need to add `operator new` overloads to `CHeapObj<>` and possibly in
+other places in order to support this. However, it has been suggested that
+implementing it (efficiently) on top of NMT might be difficult. Note that
+`posix_memalign` / `_aligned_malloc` don't help here, because of NMT's use of
+malloc headers.
+
+If we don't support it we may want to add `operator new` overloads that are
+deleted, to prevent attempted uses.
+
+Alignment usage in non-HotSpot parts of the OpenJDK:
+
+* `alignas` used once in harfbuzz, to align a variable.
+
+* libpipewire has `#define SPA_ALIGNED` macro using gcc `aligned` attribute,
+but doesn't use it.
+
+* libsleef has `#define ALIGNED` macro using gcc `aligned` attribute. It is
+not used for class or member declarations.
+
+### `std::to_chars()` and `std::from_chars`
+
+It is undecided whether to permit the use of `std::to_chars()` and
+`std::from_chars()` ([p0067r5](http://wg21.link/p0067r5)).
+
+These functions provide low-level conversions between character sequences and
+numeric values. This seems like a good candidate for use in HotSpot,
+potentially replacing various clumsy or less performant alternatives. There is
+no memory allocation. Parsing failures are indicated via error codes rather
+than exceptions. Various other nice for HotSpot properties.
+
+Note that the published C++17 Standard puts these in `<utility>`, but a defect
+report moved them to `<charconv>`. This also needs `<system_error>`.
+
+This would require upgrading the minimum gcc version to 11.1 for floating
+point conversion support. The minimum Visual Studio version is already
+sufficient.  The minimum clang version requirement hasn't been determined yet.
+
+### `std::launder()`
+
+It is undecided whether to permit the use of `std::launder()`
+([p0137r1](http://wg21.link/p0137r1)).
+
+Change to permitted if we discover a place where we need it. Or maybe we
+should just permit it, but hope we don't need it.
+
+Also, C++20 revised the relevant part of Object Lifetime in a way that seems
+more permissive and with less need of laundering. We don't know if
+implementations of prior versions take advantage of the difference.
+
+See Object Lifetime: C++17 6.8/8, C++20 6.7.3/8

+([n4295](http://wg21.link/n4295)) &mdash;

+% Explanation of start of release changes
+
+## Overview
+
+The start of release changes, the changes that turn JDK _N_ into JDK
+(_N_+1), are primarily small updates to various files along with new files to
+store symbol information to allow `javac --release N ...` to run on
+JDK (_N_+1).
+
+The updates include changes to files holding meta-data about the
+release, files under the `src` directory for API and tooling updates,
+and incidental updates under the `test` directory.
+
+## Details and file updates
+
+As a matter of policy, there are a number of semantically distinct
+concepts which get incremented separately at the start of a new
+release:
+
+* Feature value of `Runtime.version()`
+* Highest source version modeled by `javax.lang.model.SourceVersion`
+* Highest class file format major version recognized by the platform
+* Highest `-source`/`-target`/`--release` argument recognized by
+  `javac` and related tools
+
+The expected file updates are listed below. Additional files may need
+to be updated for a particular release.
+
+### Meta-data files
+
+* `jcheck/conf`: update meta-data used by `jcheck` and the Skara tooling
+* `make/conf/version-numbers.conf`: update to meta-data used in the build
+
+### `src` files
+
+* `src/hotspot/share/classfile/classFileParser.cpp`: add a `#define`
+  for the new version
+* `src/java.base/share/classes/java/lang/classfile/ClassFile.java`:
+  add a constant for the new class file format version
+* `src/java.base/share/classes/java/lang/reflect/ClassFileFormatVersion.java`:
+   add an `enum` constant for the new class file format version
+* `src/java.compiler/share/classes/javax/lang/model/SourceVersion.java`:
+  add an `enum` constant for the new source version
+* `src/java.compiler/share/classes/javax/lang/model/util/*` visitors: Update
+  `@SupportedSourceVersion` annotations to latest value. Note this update
+  is done in lieu of introducing another set of visitors for each Java
+  SE release.
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/code/Source.java`:
+   add an `enum` constant for the new source version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/jvm/ClassFile.java`:
+   add an `enum` constant for the new class file format version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/jvm/Target.java`:
+   add an `enum` constant for the new target version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/processing/PrintingProcessor.java`
+   update printing processor to support the new source version
+* The symbol information for `--release` is stored as new text files in the
+  `src/jdk.compiler/share/data/symbols` directory, one file per
+  module. The README file in that directory contains directions on how
+  to create the files.
+
+### `test` files
+
+* `test/langtools/tools/javac/api/TestGetSourceVersions.java`: add new `SourceVersion` constant to test matrix.
+* `test/langtools/tools/javac/classfiles/ClassVersionChecker.java`: add new enum constant for the new class file version
+* `test/langtools/tools/javac/lib/JavacTestingAbstractProcessor.java`
+   update annotation processor extended by `javac` tests to cover the new source version
+* `test/langtools/tools/javac/preview/classReaderTest/Client.nopreview.out` and `test/langtools/tools/javac/preview/classReaderTest/Client.preview.out`: update expected messages for preview errors and warnings

+### Testing Ahead-of-time Optimizations
+
+One way to improve test coverage of ahead-of-time (AOT) optimizations in
+the JDK is to run existing jtreg test cases in a special "AOT_JDK" mode.
+Example:
+
+```
+$ make test JTREG="AOT_JDK=onestep" \
+    TEST=open/test/hotspot/jtreg/runtime/invokedynamic
+```
+
+In this testing mode, we first perform an AOT training run
+(see https://openjdk.org/jeps/483) of a special test program
+([test/setup_aot/TestSetupAOT.java](../test/setup_aot/TestSetupAOT.java))
+that accesses about 5,0000 classes in the JDK core libraries.
+Optimization artifacts for these classes (such as pre-linked
+lambda expressions, execution profiles, and pre-generated native code)
+are stored into an AOT cache file, which will be used by all the JVMs
+launched by the selected jtreg test cases.
+
+When the jtreg tests call into the core libraries classes that are in
+the AOT cache, we will be able to test the AOT optimizations that were
+used on those classes.
+
+Please note that not all existing jtreg test cases can be executed with
+the AOT_JDK mode. See
+[test/hotspot/jtreg/ProblemList-AotJdk.txt](../test/hotspot/jtreg/ProblemList-AotJdk.txt)
+and [test/jdk/ProblemList-AotJdk.txt](../test/jdk/ProblemList-AotJdk.txt).
+
+Also, test cases that were written specifically to test AOT, such as the tests
+under [test/hotspot/jtreg/runtime/cds](../test/hotspot/jtreg/runtime/cds/),
+cannot be executed with the AOT_JDK mode.
+
+Valid values for `AOT_JDK` are `onestep` and `twostep`. These control how
+the AOT cache is generated. See https://openjdk.org/jeps/514 for details.
+All other values are ignored.
