+## Contributing
+
+### Start a Project Using Zig
+
+One of the best ways you can contribute to Zig is to start using it for a
+personal project. Here are some great examples:
+
+ * [Oxid](https://github.com/dbandstra/oxid) - arcade style game
+ * [TM35-Metronome](https://github.com/TM35-Metronome) - tools for modifying and randomizing Pokémon games
+ * [trOS](https://github.com/sjdh02/trOS) - tiny aarch64 baremetal OS thingy
+
+Without fail, these projects lead to discovering bugs and helping flesh out use
+cases, which lead to further design iterations of Zig. Importantly, each issue
+found this way comes with real world motivations, so it is easy to explain
+your reasoning behind proposals and feature requests.
+
+Ideally, such a project will help you to learn new skills and add something
+to your personal portfolio at the same time.
+
+### Spread the Word
+
+Another way to contribute is to write about Zig, or speak about Zig at a
+conference, or do either of those things for your project which uses Zig.
+Here are some examples:
+
+ * [Iterative Replacement of C with Zig](http://tiehuis.github.io/blog/zig1.html)
+ * [The Right Tool for the Right Job: Redis Modules & Zig](https://www.youtube.com/watch?v=eCHM8-_poZY)
+ * [Writing a small ray tracer in Rust and Zig](https://nelari.us/post/raytracer_with_rust_and_zig/)
+
+Zig is a brand new language, with no advertising budget. Word of mouth is the
+only way people find out about the project, and the more people hear about it,
+the more people will use it, and the better chance we have to take over the
+world.
+
+### Finding Contributor Friendly Issues
+
+Please note that issues labeled
+[Proposal](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3Aproposal)
+but do not also have the
+[Accepted](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3Aaccepted)
+label are still under consideration, and efforts to implement such a proposal
+have a high risk of being wasted. If you are interested in a proposal which is
+still under consideration, please express your interest in the issue tracker,
+providing extra insights and considerations that others have not yet expressed.
+The most highly regarded argument in such a discussion is a real world use case.
+
+The issue label
+[Contributor Friendly](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3A%22contributor+friendly%22)
+exists to help you find issues that are **limited in scope and/or
+knowledge of Zig internals.**
+
+### Editing Source Code
+
+First, build the Stage 1 compiler as described in [Building from Source](README.md#Building-from-Source).
+
+Zig locates lib files relative to executable path by searching up the
+filesystem tree for a sub-path of `lib/zig/std/std.zig` or `lib/std/std.zig`.
+Typically the former is an install and the latter a git working tree which
+contains the build directory.
+
+During development it is not necessary to perform installs when modifying
+stage1 or userland sources and in fact it is faster and simpler to run,
+test and debug from a git working tree.
+
+- `make` is typically sufficient to build zig during development iterations.
+- `make install` performs a build __and__ install.
+- `msbuild -p:Configuration=Release INSTALL.vcxproj` on Windows performs a
+build and install. To avoid install, pass cmake option `-DZIG_SKIP_INSTALL_LIB_FILES=ON`.
+
+To test changes, do the following from the build directory:
+
+1. Run `make` (on POSIX) or
+   `msbuild -p:Configuration=Release INSTALL.vcxproj` (on Windows).
+2. `$BUILD_DIR/zig build test` (on POSIX) or
+   `$BUILD_DIR/Release\zig.exe build test` (on Windows).
+
+That runs the whole test suite, which does a lot of extra testing that you
+likely won't always need, and can take upwards of 1 hour. This is what the
+CI server runs when you make a pull request. (Note: actually it runs a few
+more tests; keep reading.)
+
+To save time, you can add the `--help` option to the `zig build` command and
+see what options are available. One of the most helpful ones is
+`-Dskip-release`. Adding this option to the command in step 2 above will take
+the time down from around 2 hours to about 6 minutes, and this is a good
+enough amount of testing before making a pull request.
+
+Another example is choosing a different set of things to test. For example,
+`test-std` instead of `test` will only run the standard library tests, and
+not the other ones. Combining this suggestion with the previous one, you could
+do this:
+
+`$BUILD_DIR/bin/zig build test-std -Dskip-release` (on POSIX) or
+`$BUILD_DIR/Release\zig.exe build test-std -Dskip-release` (on Windows).
+
+This will run only the standard library tests, in debug mode only, for all
+targets (it will cross-compile the tests for non-native targets but not run
+them).
+
+When making changes to the compiler source code, the most helpful test step to
+run is `test-behavior`. When editing documentation it is `docs`. You can find
+this information and more in the `--help` menu.
+
+#### Testing Non-Native Architectures with QEMU
+
+The Linux CI server additionally has qemu installed and sets `-Denable-qemu`.
+This provides test coverage for, e.g. aarch64 even on x86_64 machines. It's 
+recommended for Linux users to install qemu and enable this testing option
+when editing the standard library or anything related to a non-native
+architecture.
+
+##### glibc
+
+Testing foreign architectures with dynamically linked glibc is one step trickier.
+This requires enabling `-Denable-foreign-glibc=/path/to/glibc/multi/install/glibcs`.
+This path is obtained by building glibc for multiple architectures. This
+process for me took an entire day to complete and takes up 65 GiB on my hard
+drive. The CI server does not provide this test coverage. Instructions for
+producing this path can be found
+[on the wiki](https://github.com/ziglang/zig/wiki/Updating-libc#glibc).
+Just the part with `build-many-glibcs.py`.
+
+It's understood that most contributors will not have these tests enabled.
+
+#### Testing Windows from a Linux Machine with Wine
+
+When developing on Linux, another option is available to you: `-Denable-wine`.
+This will enable running behavior tests and std lib tests with Wine. It's
+recommended for Linux users to install Wine and enable this testing option 
+when editing the standard library or anything Windows-related.
+
+#### Improving Translate-C
+
+Please read the [Editing Source Code](#editing-source-code) section as a
+prerequisite to this one.
+
+`translate-c` is a feature provided by Zig that converts C source code into
+Zig source code. It powers the `zig translate-c` command as well as
+[@cImport](https://ziglang.org/documentation/master/#cImport), allowing Zig
+code to not only take advantage of function prototypes defined in .h files,
+but also `static inline` functions written in C, and even some macros.
+
+This feature works by using libclang API to parse and semantically analyze
+C/C++ files, and then based on the provided AST and type information,
+generating Zig AST, and finally using the mechanisms of `zig fmt` to render
+the Zig AST to a file.
+
+The relevant tests for this feature are:
+
+ * `test/run_translated_c.zig` - each test case is C code with a `main` function. The C code
+   is translated into Zig code, compiled, and run, and tests that the expected output is the
+   same, and that the program exits cleanly. This kind of test coverage is preferred, when
+   possible, because it makes sure that the resulting Zig code is actually viable.
+
+ * `test/stage1/behavior/translate_c_macros.zig` - each test case consists of a Zig test 
+   which checks that the relevant macros in `test/stage1/behavior/translate_c_macros.h`.
+   have the correct values. Macros have to be tested separately since they are expanded by
+   Clang in `run_translated_c` tests.
+
+ * `test/translate_c.zig` - each test case is C code, with a list of expected strings which
+   must be found in the resulting Zig code. This kind of test is more precise in what it
+   measures, but does not provide test coverage of whether the resulting Zig code is valid.
+
+This feature is self-hosted, even though Zig is not fully self-hosted yet. In the Zig source
+repo, we maintain a C API on top of Clang's C++ API:
+
+ * `src/zig_clang.h` - the C API that we maintain on top of Clang's C++ API. This
+   file does not include any Clang's C++ headers. Instead, C types and C enums are defined
+   here.
+
+ * `src/zig_clang.cpp` - a lightweight wrapper that fulfills the C API on top of the
+   C++ API. It takes advantage of `static_assert` to make sure we get compile errors when
+   Clang's C++ API changes. This one file necessarily does include Clang's C++ headers, which
+   makes it the slowest-to-compile source file in all of Zig's codebase.
+
+ * `src-self-hosted/clang.zig` - the Zig equivalent of `src/zig_clang.h`. This is a manually
+   maintained list of types and functions that are ABI-compatible with the Clang C API we
+   maintain. In theory this could be generated by running translate-c on `src/zig_clang.h`,
+   but that would introduce a dependency cycle, since we are using this file to implement
+   translate-c.
+
+Finally, the actual source code for the translate-c feature is
+`src-self-hosted/translate_c.zig`. This code uses the Clang C API exposed by
+`src-self-hosted/clang.zig`, and produces Zig AST.
+
+The steps for contributing to translate-c look like this:
+
+ 1. Identify a test case you want to improve. Add it as a run-translated-c test
+    case (usually preferable), or as a translate-c test case.
+
+ 2. Edit `src-self-hosted/translate_c.zig` to improve the behavior.
+
+ 3. Run the relevant tests: `./zig build test-run-translated-c test-translate-c`

+## Resources

-## Documentation
-
-If you are looking at this README file in a source tree, please refer to the
-**Release Notes**, **Language Reference**, or **Standard Library
-Documentation** corresponding to the version of Zig that you are using by
-following the appropriate link on the
-[download page](https://ziglang.org/download).
-
-Otherwise, you're looking at a release of Zig, and you can find documentation
-here:
-
- * doc/langref.html
- * doc/std/index.html
-
-## Installation
-
- * [download a pre-built binary](https://ziglang.org/download/)
- * [install from a package manager](https://github.com/ziglang/zig/wiki/Install-Zig-from-a-Package-Manager)
- * [bootstrap zig for any target](https://github.com/ziglang/zig-bootstrap)
-
-A Zig installation is composed of two things:
-
-1. The Zig executable
-2. The lib/ directory
-
-At runtime, the executable searches up the file system for the lib/ directory,
-relative to itself:
-
-* lib/
-* lib/zig/
-* ../lib/
-* ../lib/zig/
-* (and so on)
-
-In other words, you can **unpack a release of Zig anywhere**, and then begin
-using it immediately. There is no need to install it globally, although this
-mechanism supports that use case too (i.e. `/usr/bin/zig` and `/usr/lib/zig/`).

 ## Building from Source

-Ensure you have the required dependencies:
+[![Build Status](https://dev.azure.com/ziglang/zig/_apis/build/status/ziglang.zig?branchName=master)](https://dev.azure.com/ziglang/zig/_build/latest?definitionId=1&branchName=master)

- * CMake >= 3.5
- * System C/C++ Toolchain
- * LLVM, Clang, LLD development libraries == 17.x
+Note that you can
+[download a binary of the master branch](https://ziglang.org/download/#release-master) or 
+[install Zig from a package manager](https://github.com/ziglang/zig/wiki/Install-Zig-from-a-Package-Manager).

-Then it is the standard CMake build process:
+### Stage 1: Build Zig from C++ Source Code
+
+This step must be repeated when you make changes to any of the C++ source code.
+
+#### Dependencies
+
+##### POSIX
+
+ * cmake >= 2.8.5
+ * gcc >= 5.0.0 or clang >= 3.6.0
+ * LLVM, Clang, LLD development libraries == 11.x, compiled with the same gcc or clang version above
+   - Use the system package manager, or [build from source](https://github.com/ziglang/zig/wiki/How-to-build-LLVM,-libclang,-and-liblld-from-source#posix).
+
+##### Windows
+
+ * cmake >= 3.15.3
+ * Microsoft Visual Studio. Supported versions:
+   - 2017 (version 15.8)
+   - 2019 (version 16)
+ * LLVM, Clang, LLD development libraries == 11.x
+   - Use the [pre-built binaries](https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows) or [build from source](https://github.com/ziglang/zig/wiki/How-to-build-LLVM,-libclang,-and-liblld-from-source#windows).
+
+#### Instructions
+
+##### POSIX

-[Building Zig From Source](https://github.com/ziglang/zig/wiki/Building-Zig-From-Source)
-page on the wiki.
+Need help? [Troubleshooting Build Issues](https://github.com/ziglang/zig/wiki/Troubleshooting-Build-Issues)

-## Building from Source without LLVM
-
-In this case, the only system dependency is a C compiler.
+##### MacOS

 ```
-cc -o bootstrap bootstrap.c
-./bootstrap
+brew install cmake llvm
+brew outdated llvm || brew upgrade llvm
+mkdir build
+cd build
+cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
+make install
 ```

-This produces a `zig2` executable in the current working directory. This is a
-"stage2" build of the compiler,
-[without LLVM extensions](https://github.com/ziglang/zig/issues/16270), and is
-therefore lacking these features:
- Release mode optimizations
- aarch64 machine code backend
- `@cImport` / `zig translate-c`
- Ability to compile C files
- Ability to compile assembly files
- [Some ELF linking features](https://github.com/ziglang/zig/issues/17749)
- [Most COFF/PE linking features](https://github.com/ziglang/zig/issues/17751)
- [Some WebAssembly linking features](https://github.com/ziglang/zig/issues/17750)
- [Ability to output LLVM bitcode](https://github.com/ziglang/zig/issues/13265)
- [Windows resource file compilation](https://github.com/ziglang/zig/issues/17752)
- [Ability to create import libs from def files](https://github.com/ziglang/zig/issues/17807)
- [Automatic importlib file generation for Windows DLLs](https://github.com/ziglang/zig/issues/17753)
- [Ability to create static archives from object files](https://github.com/ziglang/zig/issues/9828)
- Ability to compile C++, Objective-C, and Objective-C++ files
+##### Windows

-However, a compiler built this way does provide a C backend, which may be
-useful for creating system packages of Zig projects using the system C
-toolchain. In such case, LLVM is not needed!
+See https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows

-## Contributing
+### Stage 2: Build Self-Hosted Zig from Zig Source Code

-[Donate monthly](https://ziglang.org/zsf/).
+Now we use the stage1 binary:

-Zig is Free and Open Source Software. We welcome bug reports and patches from
-everyone. However, keep in mind that Zig governance is BDFN (Benevolent
-Dictator For Now) which means that Andrew Kelley has final say on the design
-and implementation of everything.
+```
+zig build --prefix $(pwd)/stage2 -Denable-llvm
+```

-One of the best ways you can contribute to Zig is to start using it for an
-open-source personal project.
+This produces `stage2/bin/zig` which can be used for testing and development.
+Once it is feature complete, it will be used to build stage 3 - the final compiler
+binary.

-This leads to discovering bugs and helps flesh out use cases, which lead to
-further design iterations of Zig. Importantly, each issue found this way comes
-with real world motivations, making it straightforward to explain the reasoning
-behind proposals and feature requests.
+### Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler

-You will be taken much more seriously on the issue tracker if you have a
-personal project that uses Zig.
+*Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is
+not yet supported.*

-The issue label
-[Contributor Friendly](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3A%22contributor+friendly%22)
-exists to help you find issues that are **limited in scope and/or knowledge of
-Zig internals.**
+Once the self-hosted compiler can build itself, this will be the actual
+compiler binary that we will install to the system. Until then, users should
+use stage 1.

-Please note that issues labeled
-[Proposal](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3Aproposal)
-but do not also have the
-[Accepted](https://github.com/ziglang/zig/issues?q=is%3Aissue+is%3Aopen+label%3Aaccepted)
-label are still under consideration, and efforts to implement such a proposal
-have a high risk of being wasted. If you are interested in a proposal which is
-still under consideration, please express your interest in the issue tracker,
-providing extra insights and considerations that others have not yet expressed.
-The most highly regarded argument in such a discussion is a real world use case.
+#### Debug / Development Build

-For more tips, please see the
-[Contributing](https://github.com/ziglang/zig/wiki/Contributing) page on the
-wiki.
+```
+stage2/bin/zig build
+```

-## Community
+This produces `zig-cache/bin/zig`.

-The Zig community is decentralized. Anyone is free to start and maintain their
-own space for Zig users to gather. There is no concept of "official" or
-"unofficial". Each gathering place has its own moderators and rules. Users are
-encouraged to be aware of the social structures of the spaces they inhabit, and
-work purposefully to facilitate spaces that align with their values.
+#### Release / Install Build

-Please see the [Community](https://github.com/ziglang/zig/wiki/Community) wiki
-page for a public listing of social spaces.
+```
+stage2/bin/zig build install -Drelease
+```
+
+## License
+
+The ultimate goal of the Zig project is to serve users. As a first-order
+effect, this means users of the compiler, helping programmers to write better
+software. Even more important, however, are the end-users.
+
+Zig is intended to be used to help **end-users** accomplish their goals. Zig
+should be used to empower end-users, never to exploit them financially, or to
+limit their freedom to interact with hardware or software in any way.
+
+However, such problems are best solved with social norms, not with software
+licenses. Any attempt to complicate the software license of Zig would risk
+compromising the value Zig provides.
+
+Therefore, Zig is available under the MIT (Expat) License, and comes with a
+humble request: use it to make software better serve the needs of end-users.
+
+This project redistributes code from other projects, some of which have other
+licenses besides MIT. Such licenses are generally similar to the MIT license
+for practical purposes. See the subdirectories and files inside lib/ for more
+details.

+John R. Hauser<BR>
+2018 January 20<BR>
+</P>
+
+
+<H3>Release 3e (2018 January)</H3>
+
+<UL>
+
+<LI>
+Changed the default numeric code for optional rounding mode <CODE>odd</CODE>
+(round to odd, also known as <EM>jamming</EM>) from 5 to 6.
+
+<LI>
+Modified the behavior of rounding mode <CODE>odd</CODE> when rounding to an
+integer value (either conversion to an integer format or a
+&lsquo;<CODE>roundToInt</CODE>&rsquo; function).
+Previously, for those cases only, rounding mode <CODE>odd</CODE> acted the same
+as rounding to minimum magnitude.
+Now all operations are rounded consistently.
+
+<LI>
+Fixed some errors in the specialization code modeling Intel x86 floating-point,
+specifically the integers returned on invalid operations and the propagation of
+NaN payloads in a few rare cases.
+
+<LI>
+Added specialization code modeling ARM floating-point, conforming to VFPv2 or
+later.
+
+<LI>
+Added an example target for ARM processors.
+
+<LI>
+Fixed a minor bug whereby function <CODE>f16_to_ui64</CODE> might return a
+different integer than expected in the case that the floating-point operand is
+negative.
+
+<LI>
+Added example target-specific optimization for GCC, employing GCC instrinsics
+and support for <NOBR>128-bit</NOBR> integer arithmetic.
+
+<LI>
+Made other minor improvements.
+
+</UL>
+
+
+<H3>Release 3d (2017 August)</H3>
+
+<UL>
+
+<LI>
+Fixed bugs in the square root functions for <NOBR>64-bit</NOBR>
+double-precision, <NOBR>80-bit</NOBR> double-extended-precision, and
+<NOBR>128-bit</NOBR> quadruple-precision.
+For <NOBR>64-bit</NOBR> double-precision (<CODE>f64_sqrt</CODE>), the result
+could sometimes be off by <NOBR>1 unit</NOBR> in the last place
+(<NOBR>1 ulp</NOBR>) from what it should be.
+For the larger formats, the square root could be wrong in a large portion of
+the less-significant bits.
+(A bug in <CODE>f128_sqrt</CODE> was first reported by Alexei Sibidanov.)
+
+</UL>
+
+
+<H3>Release 3c (2017 February)</H3>
+
+<UL>
+
+<LI>
+Added optional rounding mode <CODE>odd</CODE> (round to odd, also known as
+<EM>jamming</EM>).
+
+<LI>
+Corrected the documentation concerning non-canonical representations in
+<NOBR>80-bit</NOBR> double-extended-precision.
+
+</UL>
+
+
+<H3>Release 3b (2016 July)</H3>
+
+<UL>
+
+<LI>
+Implemented the common <NOBR>16-bit</NOBR> &ldquo;half-precision&rdquo;
+floating-point format (<CODE>float16_t</CODE>).
+
+<LI>
+Made the integer values returned on invalid conversions to integer formats
+be determined by the port-specific specialization instead of being the same for
+all ports.
+
+<LI>
+Added preprocessor macro <CODE>THREAD_LOCAL</CODE> to allow the floating-point
+state (modes and exception flags) to be made per-thread.
+
+<LI>
+Modified the provided Makefiles to allow some options to be overridden from the
+<CODE>make</CODE> command.
+
+<LI>
+Made other minor improvements.
+
+</UL>
+
+
+<H3>Release 3a (2015 October)</H3>
+
+<UL>
+
+<LI>
+Replaced the license text supplied by the University of California, Berkeley.
+
+</UL>
+
+
+<H3>Release 3 (2015 February)</H3>
+
+<UL>
+
+<LI>
+Complete rewrite, funded by the University of California, Berkeley, and
+consequently having a different use license than earlier releases.
+Major changes included renaming most types and functions, upgrading some
+algorithms, restructuring the source files, and making SoftFloat into a true
+library.
+
+<LI>
+Added functions to convert between floating-point and unsigned integers, both
+<NOBR>32-bit</NOBR> and <NOBR>64-bit</NOBR> (<CODE>uint32_t</CODE> and
+<CODE>uint64_t</CODE>).
+
+<LI>
+Added functions for fused multiply-add, for all supported floating-point
+formats except <NOBR>80-bit</NOBR> double-extended-precision.
+
+<LI>
+Added support for a fifth rounding mode, <CODE>near_maxMag</CODE> (round to
+nearest, with ties to maximum magnitude, away from zero).
+
+<LI>
+Dropped the <CODE>timesoftfloat</CODE> program (now part of the Berkeley
+TestFloat package).
+
+</UL>
+
+
+<H3>Release 2c (2015 January)</H3>
+
+<UL>
+
+<LI>
+Fixed mistakes affecting some <NOBR>64-bit</NOBR> processors.
+
+<LI>
+Further improved the documentation and the wording for the legal restrictions
+on using SoftFloat releases <NOBR>through 2c</NOBR> (not applicable to
+<NOBR>Release 3</NOBR> or later).
+
+</UL>
+
+
+<H3>Release 2b (2002 May)</H3>
+
+<UL>
+
+<LI>
+Made minor updates to the documentation, including improved wording for the
+legal restrictions on using SoftFloat.
+
+</UL>
+
+
+<H3>Release 2a (1998 December)</H3>
+
+<UL>
+
+<LI>
+Added functions to convert between <NOBR>64-bit</NOBR> integers
+(<CODE>int64</CODE>) and all supported floating-point formats.
+
+<LI>
+Fixed a bug in all <NOBR>64-bit</NOBR>-version square root functions except
+<CODE>float32_sqrt</CODE> that caused the result sometimes to be off by
+<NOBR>1 unit</NOBR> in the last place (<NOBR>1 ulp</NOBR>) from what it should
+be.
+(Bug discovered by Paul Donahue.)
+
+<LI>
+Improved the Makefiles.
+</UL>
+
+
+<H3>Release 2 (1997 June)</H3>
+
+<UL>
+
+<LI>
+Created the <NOBR>64-bit</NOBR> (<CODE>bits64</CODE>) version, adding the
+<CODE>floatx80</CODE> and <CODE>float128</CODE> formats.
+
+<LI>
+Changed the source directory structure, splitting the sources into a
+<CODE>bits32</CODE> and a <CODE>bits64</CODE> version.
+Renamed <CODE>environment.h</CODE> to <CODE>milieu.h</CODE> to avoid confusion
+with environment variables.
+
+<LI>
+Fixed a small error that caused <CODE>float64_round_to_int</CODE> often to
+round the wrong way in nearest/even mode when the operand was between
+2<SUP>20</SUP> and 2<SUP>21</SUP> and halfway between two integers.
+
+</UL>
+
+
+<H3>Release 1a (1996 July)</H3>
+
+<UL>
+
+<LI>
+Corrected a mistake that caused borderline underflow cases not to raise the
+underflow flag when they should have.
+(Problem reported by Doug Priest.)
+
+<LI>
+Added the <CODE>float_detect_tininess</CODE> variable to control whether
+tininess is detected before or after rounding.
+
+</UL>
+
+
+<H3>Release 1 (1996 July)</H3>
+
+<UL>
+
+<LI>
+Original release, based on work done for the International Computer Science

+<H2>1. Introduction</H2>
+
+<P>
+This document gives information needed for compiling and/or porting Berkeley
+SoftFloat, a library of C functions implementing binary floating-point
+conforming to the IEEE Standard for Floating-Point Arithmetic.
+For basic documentation about SoftFloat refer to
+<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>.
+</P>
+
+<P>
+The source code for SoftFloat is intended to be relatively machine-independent
+and should be compilable with any ISO-Standard C compiler that also supports
+<NOBR>64-bit</NOBR> integers.
+SoftFloat has been successfully compiled with the GNU C Compiler
+(<CODE>gcc</CODE>) for several platforms.
+</P>
+
+<P>
+<NOBR>Release 3</NOBR> of SoftFloat was a complete rewrite relative to
+<NOBR>Release 2</NOBR> or earlier.
+Changes to the interface of SoftFloat functions are documented in
+<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>.
+The current version of SoftFloat is <NOBR>Release 3e</NOBR>.
+</P>
+
+
+<H2>2. Limitations</H2>
+
+<P>
+SoftFloat assumes the computer has an addressable byte size of either 8 or
+<NOBR>16 bits</NOBR>.
+(Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.)
+</P>
+
+<P>
+SoftFloat is written in C and is designed to work with other C code.
+The C compiler used must conform at a minimum to the 1989 ANSI standard for the
+C language (same as the 1990 ISO standard) and must in addition support basic
+arithmetic on <NOBR>64-bit</NOBR> integers.
+Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR>
+single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that
+did not require <NOBR>64-bit</NOBR> integers, but this option is not supported
+starting with <NOBR>Release 3</NOBR>.
+Since 1999, ISO standards for C have mandated compiler support for
+<NOBR>64-bit</NOBR> integers.
+A compiler conforming to the 1999 C Standard or later is recommended but not
+strictly required.
+</P>
+
+<P>
+<NOBR>C Standard</NOBR> header files <CODE>&lt;stdbool.h&gt;</CODE> and
+<CODE>&lt;stdint.h&gt;</CODE> are required for defining standard Boolean and
+integer types.
+If these headers are not supplied with the C compiler, minimal substitutes must
+be provided.
+SoftFloat&rsquo;s dependence on these headers is detailed later in
+<NOBR>section 5.1</NOBR>, <I>Standard Headers <CODE>&lt;stdbool.h&gt;</CODE>
+and <CODE>&lt;stdint.h&gt;</CODE></I>.

+The SoftFloat package was written by me, <NOBR>John R.</NOBR> Hauser.
+<NOBR>Release 3</NOBR> of SoftFloat was a completely new implementation
+supplanting earlier releases.
+The project to create <NOBR>Release 3</NOBR> (now <NOBR>through 3e</NOBR>) was
+done in the employ of the University of California, Berkeley, within the
+Department of Electrical Engineering and Computer Sciences, first for the
+Parallel Computing Laboratory (Par Lab) and then for the ASPIRE Lab.
+The work was officially overseen by Prof. Krste Asanovic, with funding provided
+by these sources:

+<H2>4. SoftFloat Package Directory Structure</H2>
+
+<P>
+Because SoftFloat is targeted to multiple platforms, its source code is
+slightly scattered between target-specific and target-independent directories
+and files.
+The supplied directory structure is as follows:
+<BLOCKQUOTE>
+<PRE>
+doc
+source
+    include
+    8086
+    8086-SSE
+    ARM-VFPv2
+    ARM-VFPv2-defaultNaN
+build
+    template-FAST_INT64
+    template-not-FAST_INT64
+    Linux-386-GCC
+    Linux-386-SSE2-GCC

+    Linux-ARM-VFPv2-GCC
+    Win32-MinGW
+    Win32-SSE2-MinGW
+    Win64-MinGW-w64
+</PRE>
+</BLOCKQUOTE>
+The majority of the SoftFloat sources are provided in the <CODE>source</CODE>
+directory.
+The <CODE>include</CODE> subdirectory contains several header files
+(unsurprisingly), while the other subdirectories of <CODE>source</CODE> contain
+source files that specialize the floating-point behavior to match particular
+processor families:
+<BLOCKQUOTE>
+<DL>
+<DT><CODE>8086</CODE></DT>
+<DD>
+Intel&rsquo;s older, 8087-derived floating-point, extended to all supported
+floating-point types
+</DD>
+<DT><CODE>8086-SSE</CODE></DT>
+<DD>
+Intel&rsquo;s x86 processors with Streaming SIMD Extensions (SSE) and later
+compatible extensions, having 8087 behavior for <NOBR>80-bit</NOBR>
+double-extended-precision (<CODE>extFloat80_t</CODE>) and SSE behavior for
+other floating-point types
+</DD>
+<DT><CODE>ARM-VFPv2</CODE></DT>
+<DD>
+ARM&rsquo;s VFPv2 or later floating-point, with NaN payload propagation
+</DD>
+<DT><CODE>ARM-VFPv2-defaultNaN</CODE></DT>
+<DD>
+ARM&rsquo;s VFPv2 or later floating-point, with the &ldquo;default NaN&rdquo;
+option
+</DD>
+</DL>
+</BLOCKQUOTE>
+If other specializations are attempted, these would be expected to be other
+subdirectories of <CODE>source</CODE> alongside the ones listed above.
+Specialization is covered later, in <NOBR>section 5.2</NOBR>, <I>Specializing
+Floating-Point Behavior</I>.
+</P>
+
+<P>
+The <CODE>build</CODE> directory is intended to contain a subdirectory for each
+target platform for which a build of the SoftFloat library may be created.
+For each build target, the target&rsquo;s subdirectory is where all derived
+object files and the completed SoftFloat library (typically
+<CODE>softfloat.a</CODE> or <CODE>libsoftfloat.a</CODE>) are created.
+The two <CODE>template</CODE> subdirectories are not actual build targets but
+contain sample files for creating new target directories.
+(The meaning of <CODE>FAST_INT64</CODE> will be explained later.)
+</P>
+
+<P>
+Ignoring the <CODE>template</CODE> directories, the supplied target directories
+are intended to follow a naming system of
+<NOBR><CODE>&lt;<I>execution-environment</I>&gt;-&lt;<I>compiler</I>&gt;</CODE></NOBR>.
+For the example targets,
+<NOBR><CODE>&lt;<I>execution-environment</I>&gt;</CODE></NOBR> is
+<NOBR><CODE>Linux-386</CODE></NOBR>, <NOBR><CODE>Linux-386-SSE2</CODE></NOBR>,
+<NOBR><CODE>Linux-x86_64</CODE></NOBR>,
+<NOBR><CODE>Linux-ARM-VFPv2</CODE></NOBR>, <CODE>Win32</CODE>,
+<NOBR><CODE>Win32-SSE2</CODE></NOBR>, or <CODE>Win64</CODE>, and
+<NOBR><CODE>&lt;<I>compiler</I>&gt;</CODE></NOBR> is <CODE>GCC</CODE>,
+<CODE>MinGW</CODE>, or <NOBR><CODE>MinGW-w64</CODE></NOBR>.
+</P>
+
+<P>
+All of the supplied target directories are merely examples that may or may not
+be correct for compiling on any particular system.
+Despite requests, there are currently no plans to include and maintain in the
+SoftFloat package the build files needed for a great many users&rsquo;
+compilation environments, which can span a huge range of operating systems,
+compilers, and other tools.
+</P>
+
+<P>
+As supplied, each target directory contains two files:
+<BLOCKQUOTE>
+<PRE>
+Makefile
+platform.h
+</PRE>
+</BLOCKQUOTE>
+The provided <CODE>Makefile</CODE> is written for GNU <CODE>make</CODE>.
+A build of SoftFloat for the specific target is begun by executing the
+<CODE>make</CODE> command with the target directory as the current directory.
+A completely different build tool can be used if an appropriate
+<CODE>Makefile</CODE> equivalent is created.
+</P>
+
+<P>
+The <CODE>platform.h</CODE> header file exists to provide a location for
+additional C declarations specific to the build target.
+Every C source file of SoftFloat contains a <CODE>#include</CODE> for
+<CODE>platform.h</CODE>.
+In many cases, the contents of <CODE>platform.h</CODE> can be as simple as one
+or two lines of code.
+At the other extreme, to get maximal performance from SoftFloat, it may be
+desirable to include in header <CODE>platform.h</CODE> (directly or via
+<CODE>#include</CODE>) declarations for numerous target-specific optimizations.
+Such possibilities are discussed in the next section, <I>Issues for Porting
+SoftFloat to a New Target</I>.
+If the target&rsquo;s compiler or library has bugs or other shortcomings,
+workarounds for these issues may also be possible with target-specific
+declarations in <CODE>platform.h</CODE>, avoiding the need to modify the main
+SoftFloat sources.
+</P>
+
+
+<H2>5. Issues for Porting SoftFloat to a New Target</H2>
+
+<H3>5.1. Standard Headers <CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE></H3>
+
+<P>
+The SoftFloat sources make use of standard headers
+<CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE>, which have
+been part of the ISO C Standard Library since 1999.
+With any recent compiler, these standard headers are likely to be supported,
+even if the compiler does not claim complete conformance to the latest ISO C
+Standard.
+For older or nonstandard compilers, substitutes for
+<CODE>&lt;stdbool.h&gt;</CODE> and <CODE>&lt;stdint.h&gt;</CODE> may need to be
+created.
+SoftFloat depends on these names from <CODE>&lt;stdbool.h&gt;</CODE>:
+<BLOCKQUOTE>
+<PRE>
+bool
+true
+false
+</PRE>
+</BLOCKQUOTE>
+and on these names from <CODE>&lt;stdint.h&gt;</CODE>:
+<BLOCKQUOTE>
+<PRE>
+uint16_t
+uint32_t
+uint64_t
+int32_t

+</PRE>
+</BLOCKQUOTE>
+</P>
+
+
+<H3>5.2. Specializing Floating-Point Behavior</H3>
+
+<P>
+The IEEE Floating-Point Standard allows for some flexibility in a conforming
+implementation, particularly concerning NaNs.
+The SoftFloat <CODE>source</CODE> directory is supplied with some
+<I>specialization</I> subdirectories containing possible definitions for this
+implementation-specific behavior.
+For example, the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR>
+subdirectories have source files that specialize SoftFloat&rsquo;s behavior to
+match that of Intel&rsquo;s x86 line of processors.
+The files in a specialization subdirectory must determine:
+<UL>
+<LI>
+whether tininess for underflow is detected before or after rounding by default;
+<LI>
+how signaling NaNs are distinguished from quiet NaNs;
+<LI>
+what (if anything) special happens when exceptions are raised;
+<LI>
+the default generated quiet NaNs;
+<LI>
+how NaNs are propagated from function inputs to output; and
+<LI>
+the integer results returned when conversions to integer type raise the
+<I>invalid</I> exception.
+</UL>
+</P>
+
+<P>
+As provided, the build process for a target expects to involve exactly
+<EM>one</EM> specialization directory that defines <EM>all</EM> of these
+implementation-specific details for the target.
+A specialization directory such as <CODE>8086</CODE> is expected to contain a
+header file called <CODE>specialize.h</CODE>, together with whatever other
+source files are needed to complete the specialization.
+</P>
+
+<P>
+A new build target may use an existing specialization, such as the ones
+provided by the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR>
+subdirectories.
+If a build target needs a new specialization, different from any existing ones,
+it is recommended that a new specialization directory be created for this
+purpose.
+The <CODE>specialize.h</CODE> header file from any of the provided
+specialization subdirectories can be used as a model for what definitions are
+needed.
+</P>
+
+
+<H3>5.3. Macros for Build Options</H3>
+
+<P>
+The SoftFloat source files adapt the floating-point implementation according to
+several C preprocessor macros:
+<BLOCKQUOTE>
+<DL>
+<DT><CODE>LITTLEENDIAN</CODE>
+<DD>
+Must be defined for little-endian machines; must not be defined for big-endian
+machines.
+<DT><CODE>INLINE</CODE>
+<DD>
+Specifies the sequence of tokens used to indicate that a C function should be
+inlined.
+If macro <CODE>INLINE_LEVEL</CODE> is defined with a value of 1 or higher, this
+macro must be defined; otherwise, this macro is ignored and need not be
+defined.
+For compilers that conform to the C Standard&rsquo;s rules for inline
+functions, this macro can be defined as the single keyword <CODE>inline</CODE>.
+For other compilers that follow a convention pre-dating the standardization of
+<CODE>inline</CODE>, this macro may need to be defined to <CODE>extern</CODE>
+<CODE>inline</CODE>.
+<DT><CODE>THREAD_LOCAL</CODE>
+<DD>
+Can be defined to a sequence of tokens that, when appearing at the start of a
+variable declaration, indicates to the C compiler that the variable is
+<I>per-thread</I>, meaning that each execution thread gets its own separate
+instance of the variable.
+This macro is used in header <CODE>softfloat.h</CODE> in the declarations of
+variables <CODE>softfloat_roundingMode</CODE>,
+<CODE>softfloat_detectTininess</CODE>, <CODE>extF80_roundingPrecision</CODE>,
+and <CODE>softfloat_exceptionFlags</CODE>.
+If macro <CODE>THREAD_LOCAL</CODE> is left undefined, these variables will
+default to being ordinary global variables.
+Depending on the compiler, possible valid definitions of this macro include
+<CODE>_Thread_local</CODE> and <CODE>__thread</CODE>.
+</DL>
+<DL>
+<DT><CODE>SOFTFLOAT_ROUND_ODD</CODE>
+<DD>
+Can be defined to enable support for optional rounding mode
+<CODE>softfloat_round_odd</CODE>.
+</DL>
+<DL>
+<DT><CODE>INLINE_LEVEL</CODE>
+<DD>
+Can be defined to an integer to determine the degree of inlining requested of
+the compiler.
+Larger numbers request that more inlining be done.
+If this macro is not defined or is defined to a value less <NOBR>than 1</NOBR>
+(zero or negative), no inlining is requested.
+The maximum effective value is no higher <NOBR>than 5</NOBR>.
+Defining this macro to a value greater than 5 is the same as defining it
+<NOBR>to 5</NOBR>.
+<DT><CODE>SOFTFLOAT_FAST_INT64</CODE>
+<DD>
+Can be defined to indicate that the build target&rsquo;s implementation of
+<NOBR>64-bit</NOBR> arithmetic is efficient.
+For newer <NOBR>64-bit</NOBR> processors, this macro should usually be defined.
+For very small microprocessors whose buses and registers are <NOBR>8-bit</NOBR>
+or <NOBR>16-bit</NOBR> in size, this macro should usually not be defined.
+Whether this macro should be defined for a <NOBR>32-bit</NOBR> processor may
+depend on the target machine and the applications that will use SoftFloat.
+<DT><CODE>SOFTFLOAT_FAST_DIV32TO16</CODE>
+<DD>
+Can be defined to indicate that the target&rsquo;s division operator
+<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for
+dividing a <NOBR>32-bit</NOBR> unsigned integer by a <NOBR>16-bit</NOBR>
+unsigned integer.
+Setting this macro may affect the performance of function <CODE>f16_div</CODE>.
+<DT><CODE>SOFTFLOAT_FAST_DIV64TO32</CODE>
+<DD>
+Can be defined to indicate that the target&rsquo;s division operator
+<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for
+dividing a <NOBR>64-bit</NOBR> unsigned integer by a <NOBR>32-bit</NOBR>
+unsigned integer.
+Setting this macro may affect the performance of division, remainder, and
+square root operations other than <CODE>f16_div</CODE>.
+</DL>
+</BLOCKQUOTE>
+</P>
+
+<P>
+Following the usual custom <NOBR>for C</NOBR>, for most of these macros (all
+except <CODE>INLINE</CODE>, <CODE>THREAD_LOCAL</CODE>, and
+<CODE>INLINE_LEVEL</CODE>), the content of any definition is irrelevant;
+what matters is a macro&rsquo;s effect on <CODE>#ifdef</CODE> directives.
+</P>
+
+<P>
+It is recommended that any definitions of macros <CODE>LITTLEENDIAN</CODE>,
+<CODE>INLINE</CODE>, and <CODE>THREAD_LOCAL</CODE> be made in a build
+target&rsquo;s <CODE>platform.h</CODE> header file, because these macros are
+expected to be determined inflexibly by the target machine and compiler.
+The other five macros select options and control optimization, and thus might
+be better located in the target&rsquo;s Makefile (or its equivalent).
+</P>
+
+
+<H3>5.4. Adapting a Template Target Directory</H3>
+
+<P>
+In the <CODE>build</CODE> directory, two <CODE>template</CODE> subdirectories
+provide models for new target directories.
+Two different templates exist because different functions are needed in the
+SoftFloat library depending on whether macro <CODE>SOFTFLOAT_FAST_INT64</CODE>
+is defined.
+If macro <CODE>SOFTFLOAT_FAST_INT64</CODE> will be defined,
+<NOBR><CODE>template-FAST_INT64</CODE></NOBR> is the template to use;
+otherwise, <NOBR><CODE>template-not-FAST_INT64</CODE></NOBR> is the appropriate
+template.
+A new target directory can be created by copying the correct template directory
+and editing the files inside.
+To avoid confusion, it would be wise to refrain from editing the files within a
+template directory directly.
+</P>
+
+
+<H3>5.5. Target-Specific Optimization of Primitive Functions</H3>
+
+<P>
+Header file <CODE>primitives.h</CODE> (in directory
+<CODE>source/include</CODE>) declares macros and functions for numerous
+underlying arithmetic operations upon which many of SoftFloat&rsquo;s
+floating-point functions are ultimately built.
+The SoftFloat sources include implementations of all of these functions/macros,
+written as standard C code, so a complete and correct SoftFloat library can be
+created using only the supplied code for all functions.
+However, for many targets, SoftFloat&rsquo;s performance can be improved by
+substituting target-specific implementations of some of the functions/macros
+declared in <CODE>primitives.h</CODE>.
+</P>
+
+<P>
+For example, <CODE>primitives.h</CODE> declares a function called
+<CODE>softfloat_countLeadingZeros32</CODE> that takes an unsigned
+<NOBR>32-bit</NOBR> integer as an argument and returns the number of the
+integer&rsquo;s most-significant bits that are zeros.
+While the SoftFloat sources include an implementation of this function written
+in <NOBR>standard C</NOBR>, many processors can perform this same function
+directly in only one or two machine instructions.
+An alternative, target-specific implementation that maps to those instructions
+is likely to be more efficient than the generic C code from the SoftFloat
+package.
+</P>
+
+<P>
+A build target can replace the supplied version of any function or macro of
+<CODE>primitives.h</CODE> by defining a macro with the same name in the
+target&rsquo;s <CODE>platform.h</CODE> header file.
+For this purpose, it may be helpful for <CODE>platform.h</CODE> to
+<CODE>#include</CODE> header file <CODE>primitiveTypes.h</CODE>, which defines
+types used for arguments and results of functions declared in
+<CODE>primitives.h</CODE>.
+When a desired replacement implementation is a function, not a macro, it is
+sufficient for <CODE>platform.h</CODE> to include the line
+<BLOCKQUOTE>
+<PRE>
+#define &lt;<I>function-name</I>&gt; &lt;<I>function-name</I>&gt;
+</PRE>
+</BLOCKQUOTE>
+where <NOBR><CODE>&lt;<I>function-name</I>&gt;</CODE></NOBR> is the name of the
+function.
+This technically defines <NOBR><CODE>&lt;<I>function-name</I>&gt;</CODE></NOBR>
+as a macro, but one that resolves to the same name, which may then be a
+function.
+(A preprocessor that conforms to the C Standard is required to limit recursive
+macro expansion from being applied more than once.)
+</P>
+
+<P>
+The supplied header file <CODE>opts-GCC.h</CODE> (in directory
+<CODE>source/include</CODE>) provides an example of target-specific
+optimization for the GCC compiler.
+Each GCC target example in the <CODE>build</CODE> directory has
+<BLOCKQUOTE>
+<CODE>#include "opts-GCC.h"</CODE>
+</BLOCKQUOTE>
+in its <CODE>platform.h</CODE> header file.
+Before <CODE>opts-GCC.h</CODE> is included, the following macros must be
+defined (or not) to control which features are invoked:
+<BLOCKQUOTE>
+<DL>
+<DT><CODE>SOFTFLOAT_BUILTIN_CLZ</CODE></DT>
+<DD>
+If defined, SoftFloat&rsquo;s internal
+&lsquo;<CODE>countLeadingZeros</CODE>&rsquo; functions use intrinsics
+<CODE>__builtin_clz</CODE> and <CODE>__builtin_clzll</CODE>.
+</DD>
+<DT><CODE>SOFTFLOAT_INTRINSIC_INT128</CODE></DT>
+<DD>
+If defined, SoftFloat makes use of GCC&rsquo;s nonstandard <NOBR>128-bit</NOBR>
+integer type <CODE>__int128</CODE>.
+</DD>
+</DL>
+</BLOCKQUOTE>
+On some machines, these improvements are observed to increase the speeds of
+<CODE>f64_mul</CODE> and <CODE>f128_mul</CODE> by around 20 to 25%, although
+other functions receive less dramatic boosts, or none at all.
+Results can vary greatly across different platforms.
+</P>
+
+
+<H2>6. Testing SoftFloat</H2>
+
+<P>
+SoftFloat can be tested using the <CODE>testsoftfloat</CODE> program by the
+same author.
+This program is part of the Berkeley TestFloat package available at the Web
+page
+<A HREF="http://www.jhauser.us/arithmetic/TestFloat.html"><NOBR><CODE>http://www.jhauser.us/arithmetic/TestFloat.html</CODE></NOBR></A>.
+The TestFloat package also has a program called <CODE>timesoftfloat</CODE> that
+measures the speed of SoftFloat&rsquo;s floating-point functions.
+</P>
+
+
+<H2>7. Providing SoftFloat as a Common Library for Applications</H2>
+
+<P>
+Header file <CODE>softfloat.h</CODE> defines the SoftFloat interface as seen by
+clients.
+If the SoftFloat library will be made a common library for programs on a
+system, the supplied <CODE>softfloat.h</CODE> has a couple of deficiencies for
+this purpose:
+<UL>
+<LI>
+As supplied, <CODE>softfloat.h</CODE> depends on another header,
+<CODE>softfloat_types.h</CODE>, that is not intended for public use but which
+must also be visible to the programmer&rsquo;s compiler.
+<LI>
+More troubling, at the time <CODE>softfloat.h</CODE> is included in a C source
+file, macros <CODE>SOFTFLOAT_FAST_INT64</CODE> and <CODE>THREAD_LOCAL</CODE>
+must be defined, or not defined, consistent with how these macro were defined
+when the SoftFloat library was built.
+</UL>
+In the situation that new programs may regularly <CODE>#include</CODE> header
+file <CODE>softfloat.h</CODE>, it is recommended that a custom, self-contained
+version of this header file be created that eliminates these issues.
+</P>
+
+
+<H2>8. Contact Information</H2>
+
+<P>
