-# Contributing Guidelines
-
-We'd love to accept your patches! Please read this guide first.
-
-## Identity Disclosure
-
-This project does not accept anonymous contributions. Justine Tunney
-won't merge pull requests from strangers. In order to change the Cosmo
-codebase, and have your changes be upstreamed, she has to know who you
-are. You're encouraged to disclose your full name and email address to
-the public too, by including them in your git commit messages; however
-that's not a requirement; as we're happy to respect the wishes of
-contributors who prefer to remain anonymous to the public.
-
-## Copyright Assignment
-
-The first time you send a pull request, you need to send an email to
-Justine Tunney <jtunney@gmail.com> stating that you intend to assign her
-the copyright to the changes you contribute to Cosmopolitan. It only
-needs to happen once. This only applies to the code you *choose* to
-contribute. The email should be sent from an email address associated
-with your identity. Your email should link to your pull request.
-
-To make things easy, here's an example of a good email you can use:
-
-> **From**: YOUR NAME (yname@gmail.com)  
-> **To**: Justine Tunney (jtunney@gmail.com)  
-> **Subject**: Cosmopolitan Copyright Assignment for YOUR NAME
->
-> Hi Justine,
->
-> I made my first contribution to Cosmopolitan in
-> https://github.com/jart/cosmopolitan/pull/XXXX could you please take a
-> look? I intend to assign you the copyright to the changes I contribute
-> to Cosmopolitan.
->
-> Thanks!
-
-Please note that in order to give Justine the copyright, it has to be
-yours to give in the first place. If you're employed, then you should
-get your employer's approval to do this beforehand. Even with big
-companies like Google, this process is quick and painless. Usually we
-see employers granting authorization in less than one day.
-
-If you live in a country that doesn't recognize one's ability to assign
-copyright, then you may alternatively consider disclaiming it using the
-language in [Unlicense](https://unlicense.org) or
-[CC-0](http://creativecommons.org/share-your-work/public-domain/cc0).
-
-If you're checking-in third party code, then you need to have headers at
-the top of each source file (but never header files) documenting its
-owners and the code should go in the `third_party/` folder. Every third
-party project should have a `README.cosmo` file that documents its
-provenance as well as any local changes you've made.
-
-## Copyright Policy Exceptions
-
-### Tests
-
-You're encoraged to claim ownership of your test code. If you add a new
-file under the `test/` directory, then you should put your name in the
-ISC license header at the top of the file. If you add new test cases to
-an existing unit test file, then you're encouraged to append a line with
-your name to the existing copyright header of that file.
-
-### Exceptional Features
-
-Let's say you discovered a faster better way to implement `log10()` and
-you want to give it to Cosmopolitan. In cases like this, it really isn't
-appropriate for Justine to own your code. What you could do instead, is
-write your own new and improved `log10.c` from scratch, put your name on
-the top with the ISC license, and then add a `__notice()` directive so
-that your name will be embedded inside every executable that links the
-`log10()` function. This will help you get your name out there. Please
-note you need get approval from Justine each time you want to do this.
-
-## Style Guide
-
-You can use clang-format to automatically format your files:
-
-```sh
-clang-format -i -style=file tool/net/redbean.c
-```
-
-If you use Emacs this can be automated on save for Cosmopolitan using
-[tool/emacs/cosmo-format.el](tool/emacs/cosmo-format.el).

-documentation](https://justine.lol/cosmopolitan/documentation.html).
 
 ## Getting Started
 
-You can start by obtaining a release of our `cosmocc` compiler from
+If you're doing your development work on Linux or BSD then you need just
-<https://cosmo.zip/pub/cosmocc/>.
+five files to get started:
 
 ```sh
-mkdir -p cosmocc
+wget https://justine.lol/cosmopolitan/cosmopolitan.zip
-cd cosmocc
+unzip cosmopolitan.zip
-wget https://cosmo.zip/pub/cosmocc/cosmocc.zip
+printf 'main() { printf("hello world\\n"); }\n' >hello.c
-unzip cosmocc.zip
+gcc -g -Og -static -nostdlib -nostdinc -fno-pie -no-pie -mno-red-zone \
+  -fno-omit-frame-pointer -pg -mnop-mcount \
+  -o hello.com.dbg hello.c -fuse-ld=bfd -Wl,-T,ape.lds \
+  -include cosmopolitan.h crt.o ape.o cosmopolitan.a
+objcopy -S -O binary hello.com.dbg hello.com
+./hello.com
 ```
 
-Here's an example program we can write:
+If you're developing on Windows or MacOS then you need to download an
+x86_64-pc-linux-gnu toolchain beforehand. See the [Compiling on
+Windows](https://justine.lol/cosmopolitan/windows-compiling.html)
+tutorial. It's needed because the ELF object format is what makes
+universal binaries possible.
 
-```c
+Cosmopolitan can also be compiled from source on any Linux distro.
-// hello.c
-#include <stdio.h>
-
-int main() {
-  printf("hello world\n");
-}
-```
-
-It can be compiled as follows:
 
 ```sh
-cosmocc -o hello hello.c
+wget https://justine.lol/cosmopolitan/cosmopolitan-0.2.tar.gz
-./hello
+tar xf cosmopolitan-0.2.tar.gz  # see releases page
+cd cosmopolitan-0.2
+make -j16
+o//examples/hello.com
+find o -name \*.com | xargs ls -rShal | less
 ```
 
-The Cosmopolitan Libc runtime links some heavyweight troubleshooting
-features by default, which are very useful for developers and admins.
-Here's how you can log system calls:
-
-```sh
-./hello --strace
-```
-
-Here's how you can get a much more verbose log of function calls:
-
-```sh
-./hello --ftrace
-```
-
-You can use the Cosmopolitan's toolchain to build conventional open
-source projects which use autotools. This strategy normally works:
-
-```sh
-export CC=x86_64-unknown-cosmo-cc
-export CXX=x86_64-unknown-cosmo-c++
-./configure --prefix=/opt/cosmos/x86_64
-make -j
-make install
-```
-
-## Cosmopolitan Source Builds
-
-Cosmopolitan can be compiled from source on any of our supported
-platforms. The Makefile will download cosmocc automatically.
-
-It's recommended that you install a systemwide APE Loader. This command
-requires `sudo` access to copy the `ape` command to a system folder and
-register with binfmt_misc on Linux, for even more performance.
-
-```sh
-ape/apeinstall.sh
-```
-
-You can now build the mono repo with any modern version of GNU Make. To
-bootstrap your build, you can install Cosmopolitan Make from this site:
-
-https://cosmo.zip/pub/cosmos/bin/make
-
-E.g.:
-
-```sh
-curl -LO https://cosmo.zip/pub/cosmos/bin/make
-./make -j8
-o//examples/hello
-```
-
-After you've built the repo once, you can also use the make from your
-cosmocc at `.cosmocc/current/bin/make`. You might even prefer to alias
-make to `$COSMO/.cosmocc/current/bin/make`.
-
-Since the Cosmopolitan repository is very large, you might only want to
-build one particular thing. Here's an example of a target that can be
-compiled relatively quickly, which is a simple POSIX test that only
-depends on core LIBC packages.
-
-```sh
-rm -rf o//libc o//test
-.cosmocc/current/bin/make o//test/posix/signal_test
-o//test/posix/signal_test
-```
-
-Sometimes it's desirable to build a subset of targets, without having to
-list out each individual one. For example if you wanted to build and run
-all the unit tests in the `TEST_POSIX` package, you could say:
-
-```sh
-.cosmocc/current/bin/make o//test/posix
-```
-
-Cosmopolitan provides a variety of build modes. For example, if you want
-really tiny binaries (as small as 12kb in size) then you'd say:
-
-```sh
-.cosmocc/current/bin/make m=tiny
-```
-
-You can furthermore cut out the bloat of other operating systems, and
-have Cosmopolitan become much more similar to Musl Libc.
-
-```sh
-.cosmocc/current/bin/make m=tinylinux
-```
-
-For further details, see [//build/config.mk](build/config.mk).
-
-## Debugging
-
-To print a log of system calls to stderr:
-
-```sh
-cosmocc -o hello hello.c
-./hello --strace
-```
-
-To print a log of function calls to stderr:
-
-```sh
-cosmocc -o hello hello.c
-./hello --ftrace
-```
-
-Both strace and ftrace use the unbreakable kprintf() facility, which is
-able to be sent to a file by setting an environment variable.
-
-```sh
-export KPRINTF_LOG=log
-./hello --strace
-```
-
-## GDB
-
-Here's the recommended `~/.gdbinit` config:
-
-```gdb
-set host-charset UTF-8
-set target-charset UTF-8
-set target-wide-charset UTF-8
-set osabi none
-set complaints 0
-set confirm off
-set history save on
-set history filename ~/.gdb_history
-define asm
-  layout asm
-  layout reg
-end
-define src
-  layout src
-  layout reg
-end
-src
-```
-
-You normally run the `.dbg` file under gdb. If you need to debug the
-`` file itself, then you can load the debug symbols independently as
-
-```sh
-gdb foo -ex 'add-symbol-file foo.dbg 0x401000'
-```
-
-## Platform Notes
-
-### Shells
-
-If you use zsh and have trouble running APE programs try `sh -c ./prog`
-or simply upgrade to zsh 5.9+ (since we patched it two years ago). The
-same is the case for Python `subprocess`, old versions of fish, etc.
-
-### Linux
-
-Some Linux systems are configured to launch MZ executables under WINE.
-Other distros configure their stock installs so that APE programs will
-print "run-detectors: unable to find an interpreter". For example:
-
-```sh
-jart@ubuntu:~$ wget https://cosmo.zip/pub/cosmos/bin/dash
-jart@ubuntu:~$ chmod +x dash
-jart@ubuntu:~$ ./dash
-run-detectors: unable to find an interpreter for ./dash
-```
-
-You can fix that by registering APE with `binfmt_misc`:
-
-```sh
-sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf
-sudo chmod +x /usr/bin/ape
-sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
-sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
-```
-
-You should be good now. APE will not only work, it'll launch executables
-400µs faster now too. However if things still didn't work out, it's also
-possible to disable `binfmt_misc` as follows:
-
-```sh
-sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/cli'     # remove Ubuntu's MZ interpreter
-sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/status'  # remove ALL binfmt_misc entries
-```
-
-### WSL
-
-It's normally unsafe to use APE in a WSL environment, because it tries
-to run MZ executables as WIN32 binaries within the WSL environment. In
-order to make it safe to use Cosmopolitan software on WSL, run this:
-
-```sh
-sudo sh -c "echo -1 > /proc/sys/fs/binfmt_misc/WSLInterop"
-```

-# Actually Portable Executable Specification v0.1
-
-Actually Portable Executable (APE) is an executable file format that
-polyglots the Windows Portable Executable (PE) format with a UNIX Sixth
-Edition style shell script that doesn't have a shebang. This makes it
-possible to produce a single file binary that executes on the stock
-installations of the many OSes and architectures.
-
-## Supported OSes and Architectures
-
-- AMD64
-  - Linux
-  - MacOS
-  - Windows
-  - FreeBSD
-  - OpenBSD
-  - NetBSD
-  - BIOS
-
-- ARM64
-  - Linux
-  - MacOS
-  - FreeBSD
-  - Windows (non-native)
-
-## File Header
-
-APE defines three separate file magics, all of which are 8 characters
-long. Any file that starts with one of these magic values can be
-considered an APE program.
-
-### (1) APE MZ Magic
-
-- ASCII: `MZqFpD='`
-- Hex: 4d 5a 71 46 70 44 3d 27
-
-This is the canonical magic used by almost all APE programs. It enables
-maximum portability between OSes. When interpreted as a shell script, it
-is assigning a single quoted string to an unused variable. The shell
-will then ignore subsequent binary content that's placed inside the
-string.
-
-It is strongly recommended that this magic value be immediately followed
-by a newline (\n or hex 0a) character. Some shells, e.g. FreeBSD SH and
-Zsh impose a binary safety check before handing off files that don't
-have a shebang to `/bin/sh`. That check applies to the first line, which
-can't contain NUL characters.
-
-The letters were carefully chosen so as to be valid x86 instructions in
-all operating modes. This makes it possible to store a BIOS bootloader
-disk image inside an APE binary. For example, simple CLI programs built
-with Cosmopolitan Libc will boot from BIOS into long mode if they're
-treated as a floppy disk image.
-
-The letters also allow for the possibility of being treated on x86-64 as
-a flat executable, where the PE / ELF / Mach-O executable structures are
-ignored, and execution simply begins at the beginning of the file,
-similar to how MS-DOS .COM binaries work.
-
-The 0x4a relative offset of the magic causes execution to jump into the
-MS-DOS stub defined by Portable Executable. APE binaries built by Cosmo
-Libc use tricks in the MS-DOS stub to check the operating mode and then
-jump to the appropriate entrypoint, e.g. `_start()`.
-
-#### Decoded as i8086
-
-```asm
-  dec  %bp
-  pop  %dx
-  jno  0x4a
-  jo   0x4a
-```
-
-#### Decoded as i386
-
-```asm
-  push %ebp
-  pop  %edx
-  jno  0x4a
-  jo   0x4a
-```
-
-#### Decoded as x86-64
-
-```asm
-  rex.WRB
-  pop %r10
-  jno 0x4a
-  jo  0x4a
-```
-
-### (2) APE UNIX-Only Magic
-
-- ASCII: `jartsr='`
-- Hex: 6a 61 72 74 73 72 3d 27
-
-Being a novel executable format that was first published in 2020, the
-APE file format is less understood by industry tools compared to the PE,
-ELF, and Mach-O executable file formats, which have been around for
-decades. For this reason, APE programs that use the MZ magic above can
-attract attention from Windows AV software, which may be unwanted by
-developers who aren't interested in targeting the Windows platform.
-Therefore the `jartsr='` magic is defined which enables the creation of
-APE binaries that can safely target all non-Windows platforms. Even
-though this magic is less common, APE interpreters and binfmt-misc
-installations MUST support this.
-
-It is strongly recommended that this magic value be immediately followed
-by a newline (\n or hex 0a) character. Some shells, e.g. FreeBSD SH and
-Zsh impose a binary safety check before handing off files that don't
-have a shebang to `/bin/sh`. That check applies to the first line, which
-can't contain NUL characters.
-
-The letters were carefully chosen so as to be valid x86 instructions in
-all operating modes. This makes it possible to store a BIOS bootloader
-disk image inside an APE binary. For example, simple CLI programs built
-with Cosmopolitan Libc will boot from BIOS into long mode if they're
-treated as a floppy disk image.
-
-The letters also allow for the possibility of being treated on x86-64 as
-a flat executable, where the PE / ELF / Mach-O executable structures are
-ignored, and execution simply begins at the beginning of the file,
-similar to how MS-DOS .COM binaries work.
-
-The 0x78 relative offset of the magic causes execution to jump into the
-MS-DOS stub defined by Portable Executable. APE binaries built by Cosmo
-Libc use tricks in the MS-DOS stub to check the operating mode and then
-jump to the appropriate entrypoint, e.g. `_start()`.
-
-#### Decoded as i8086 / i386 / x86-64
-
-```asm
-  push $0x61
-  jb   0x78
-  jae  0x78
-```
-
-### (3) APE Debug Magic
-
-- ASCII: `APEDBG='`
-- Hex: 41 50 45 44 42 47 3d 27
-
-While APE files must be valid shell scripts, in practice, UNIX systems
-will oftentimes be configured to provide a faster safer alternative to
-loading an APE binary through `/bin/sh`. The Linux Kernel can be patched
-to have execve() recognize the APE format and directly load its embedded
-ELF header. Linux systems can also use binfmt-misc to recognize APE's MZ
-and jartsr magic, and pass them to a userspace program named `ape` that
-acts as an interpreter. In such environments, the need sometimes arises
-to be able to test that the `/bin/sh` is working correctly, in which
-case the `APEDBG='` magic is RECOMMENDED.
-
-APE interpreters, execve() implementations, and binfmt-misc installs
-MUST ignore this magic. If necessary, steps can be taken to help files
-with this magic be passed to `/bin/sh` like a normal shebang-less shell
-script for execution.
-
-## Embedded ELF Header
-
-APE binaries MAY embed an ELF header inside them. Unlike conventional
-executable file formats, this header is not stored at a fixed offset.
-It's instead encoded as octal escape codes in a shell script `printf`
-statement. For example:
-
-```
-printf '\177ELF\2\1\1\011\0\0\0\0\0\0\0\0\2\0\076\0\1\0\0\0\166\105\100\000\000\000\000\000\060\013\000\000\000\000\000\000\000\000\000\000\000\000\000\000\165\312\1\1\100\0\070\0\005\000\0\0\000\000\000\000'
-```
-
-This `printf` statement MUST appear in the first 8192 bytes of the APE
-executable, so as to limit how much of the initial portion of a file an
-interpreter must load.
-
-Multiple such `printf` statements MAY appear in the first 8192 bytes, in
-order to specify multiple architectures. For example, fat binaries built
-by the `apelink` program (provided by Cosmo Libc) will have two encoded
-ELF headers, for AMD64 and ARM64, each of which point into the proper
-file offsets for their respective native code. Therefore, kernels and
-interpreters which load the APE format directly MUST check the
-`e_machine` field of the `Elf64_Ehdr` that's decoded from the octal
-codes, before accepting a `printf` shell statement as valid.
-
-These printf statements MUST always use only unescaped ASCII characters
-or octal escape codes. These printf statements MUST NOT use space saving
-escape codes such as `\n`. For example, rather than saying `\n` it would
-be valid to say `\012` instead. It's also valid to say `\12` but only if
-the encoded characters that follow aren't an octal digit.
-
-For example, the following algorithm may be used for parsing octal:
-
-```c
-static int ape_parse_octal(const unsigned char page[8192], int i, int *pc)
-{
-        int c;
-        if ('0' <= page[i] && page[i] <= '7') {
-                c = page[i++] - '0';
-                if ('0' <= page[i] && page[i] <= '7') {
-                        c *= 8;
-                        c += page[i++] - '0';
-                        if ('0' <= page[i] && page[i] <= '7') {
-                                c *= 8;
-                                c += page[i++] - '0';
-                        }
-                }
-                *pc = c;
-        }
-        return i;
-}
-```
-
-APE aware interpreters SHOULD only take `e_machine` into consideration.
-It is the responsibility of the `_start()` function to detect the OS.
-Therefore, multiple `printf` statements are only embedded in the shell
-script for different CPU architectures.
-
-The OS ABI field of an APE embedded `Elf64_Ehdr` SHOULD be set to
-`ELFOSABI_FREEBSD`, since it's the only UNIX OS APE supports that
-actually checks the field. However different values MAY be chosen for
-binaries that don't intend to have FreeBSD in their support vector.
-
-Counter-intuitively, the ARM64 ELF header is used on the MacOS ARM64
-platform when loading from fat binaries.
-
-## Embedded Mach-O Header (x86-64 only)
-
-APE shell scripts that support MacOS on AMD64 must use the `dd` command
-in a very specific way to specify how the embedded binary Macho-O header
-is copied backward to the start of the file. For example:
-
-```
-dd if="$o" of="$o" bs=8 skip=433      count=66       conv=notrunc
-```
-
-These `dd` statements have traditionally been generated by the GNU as
-and ld.bfd programs by encoding ASCII into 64-bit linker relocations,
-which necessitated a fixed width for integer values. It took several
-iterations over APE's history before we eventually got it right:
-
-- `arg="  9293"` is how we originally had ape do it
-- `arg=$((  9293))` b/c busybox sh disliked quoted space
-- `arg=9293  ` is generated by modern apelink program
-
-Software that parses the APE file format, which needs to extract the
-Macho-O x86-64 header SHOULD support the old binaries that use the
-previous encodings. To make backwards compatibility simple the following
-regular expression may be used, which generalizes to all defined
-formats:
-
-```c
-regcomp(&rx,
-        "bs="              // dd block size arg
-        "(['\"] *)?"       //   #1 optional quote w/ space
-        "(\\$\\(\\( *)?"   //   #2 optional math w/ space
-        "([[:digit:]]+)"   //   #3
-        "( *\\)\\))?"      //   #4 optional math w/ space
-        "( *['\"])?"       //   #5 optional quote w/ space
-        " +"               //
-        "skip="            // dd skip arg
-        "(['\"] *)?"       //   #6 optional quote w/ space
-        "(\\$\\(\\( *)?"   //   #7 optional math w/ space
-        "([[:digit:]]+)"   //   #8
-        "( *\\)\\))?"      //   #9 optional math w/ space
-        "( *['\"])?"       //  #10 optional quote w/ space
-        " +"               //
-        "count="           // dd count arg
-        "(['\"] *)?"       //  #11 optional quote w/ space
-        "(\\$\\(\\( *)?"   //  #12 optional math w/ space
-        "([[:digit:]]+)",  //  #13
-        REG_EXTENDED);
-```

-
-## Static Linking
-
-Actually Portable Executables are always statically linked. This
-revision of the specification does not define any facility for storing
-code in dynamic shared objects.
-
-Cosmopolitan Libc provides a solution that enables APE binaries have
-limited access to dlopen(). By manually loading a platform-specific
-executable and asking the OS-specific libc's dlopen() to load
-OS-specific libraries, it becomes possible to use GPUs and GUIs. This
-has worked great for AI projects like llamafile.
-
-There is no way for an Actually Portable Executable to interact with
-OS-specific dynamic shared object extension modules to programming
-languages. For example, a Lua interpreter compiled as an Actually
-Portable Executable would have no way of linking extension libraries
-downloaded from the Lua Rocks package manager. This is primarily because
-different OSes define incompatible ABIs.
-
-While it was possible to polyglot PE+ELF+MachO to create multi-OS
-executables, it simply isn't possible to do that same thing for
-DLL+DYLIB+SO. Therefore, in order to have DSOs, APE would need to either
-choose one of the existing formats or invent one of its own, and then
-develop its own parallel ecosystem of extension software. In the future,
-the APE specification may expand to encompass this. However the focus to
-date has been exclusively on executables with limited dlopen() support.
-
-## Application Binary Interface (ABI)
-
-APE binaries use the System V ABI, as defined by:
-
-- [System V ABI - AMD64 Architecture Processor Supplement](https://gitlab.com/x86-psABIs/x86-64-ABI)
-- AARCH64 has a uniform consensus defined by ARM Limited
-
-There are however a few changes we've had to make.
-
-### No Red Zone
-
-Actually Portable Executables that have Windows and/or bare metal in
-their support vector MUST be compiled using `-mno-red-zone`. This is
-because, on Windows, DLLs and other software lurking in the va-space
-might use tricks like SetThreadContext() to take control of a thread
-whereas on bare metal, it's also generally accepted that kernel-mode
-code cannot assume a red zone either due to hardware interrupts that
-pull the exact same kinds of stunts.
-
-APE software that only has truly System V ABI conformant OSes (e.g.
-Linux) in their support vector MAY use the red zone optimization.
-
-### Thread Local Storage
-
-#### aarch64
-
-Here's the TLS memory layout on aarch64:
-
-```
-           x28
-        %tpidr_el0
-            │
-            │    _Thread_local
-        ┌───┼───┬──────────┬──────────┐
-        │tib│dtv│  .tdata  │  .tbss   │
-        ├───┴───┴──────────┴──────────┘
-        │
-    __get_tls()
-```
-
-The ARM64 code in actually portable executables use the `x28` register
-to store the address of the thread information block. All aarch64 code
-linked into these executables SHOULD be compiled with `-ffixed-x28`
-which is supported by both Clang and GCC.
-
-The runtime library for an actually portable executables MAY choose to
-use `tpidr_el0` instead, if OSes like MacOS aren't being targeted. For
-example, if the goal is to create a Linux-only fat binary linker program
-for Musl Libc, then choosing to use the existing `tpidr_el0` convention
-would be friction-free alternative.
-
-It's not possible for an APE runtime that targets the full range of OSes
-to use the `tpidr_el0` register for TLS because Apple won't allow it. On
-MacOS ARM64 systems, this register can only be used by a runtime to
-implement the `sched_getcpu()` system call. It's reserved by MacOS.
-
-#### x86-64
-
-Here's the TLS memory layout on x86_64:
-
-```
-                          __get_tls()
-                              │
-                             %fs OpenBSD/NetBSD
-           _Thread_local      │
-    ┌───┬──────────┬──────────┼───┐
-    │pad│  .tdata  │  .tbss   │tib│
-    └───┴──────────┴──────────┼───┘
-                              │
-   Linux/FreeBSD/Windows/Mac %gs
-```
-
-Quite possibly the greatest challenge in Actually Portable Executable
-working, has been overcoming the incompatibilities between OSes in how
-thread-local storage works on x86-64. The AMD64 architecture defines two
-special segment registers. Every OS uses one of these segment registers
-to implement TLS support. However not all OSes agree on which register
-to use. Some OSes grant userspace the power to define either of these
-registers to hold any value that is desired. Some OSes only effectively
-allow a single one of them to be changed. Lastly, some OSes, e.g.
-Windows, claim ownership of the memory layout these registers point
-towards too.
-
-Here's a breakdown on how much power is granted to userspace runtimes by
-each OS when it comes to changing amd64 segment registers.
-
-|         | %fs          | %gs          |
-|---------|--------------|--------------|
-| Linux   | unrestricted | unrestricted |
-| MacOS   | inaccessible | unrestricted |
-| Windows | inaccessible | restricted   |
-| FreeBSD | unrestricted | unrestricted |
-| NetBSD  | unrestricted | broken       |
-| OpenBSD | unrestricted | inaccessible |
-
-Therefore, regardless of which register one we choose, some OSes are
-going to be incompatible.
-
-APE binaries are always built with a Linux compiler. So another issue
-arises in the fact that our Linux-flavored GCC and Clang toolchains
-(which are used to produce cross-OS binaries) are also only capable of
-producing TLS instructions that use the %fs convention.
-
-To solve these challenges, the `cosmocc` compiler will rewrite binary
-objects after they've been compiled by GCC, so that the `%gs` register
-is used, rather than `%fs`. Morphing x86-64 binaries after they've been
-compiled is normally difficult, due to the complexity of the machine
-instruction language. However GCC provides `-mno-tls-direct-seg-refs`
-which greatly reduces the complexity of this task. This flag forgoes
-some optimizations to make the generated code simpler. Rather than doing
-clever arithmetic with `%fs` prefixes, the compiler will always generate
-the thread information block address load as a separate instruction.
-
-```c
-// Change AMD code to use %gs:0x30 instead of %fs:0
-// We assume -mno-tls-direct-seg-refs has been used
-static void ChangeTlsFsToGs(unsigned char *p, size_t n) {
-  unsigned char *e = p + n - 9;
-  while (p <= e) {
-    // we're checking for the following expression:
-    //   0144 == p[0] &&           // %fs
-    //   0110 == (p[1] & 0373) &&  // rex.w (and ignore rex.r)
-    //   (0213 == p[2] ||          // mov reg/mem → reg (word-sized)
-    //   0003 == p[2]) &&          // add reg/mem → reg (word-sized)
-    //   0004 == (p[3] & 0307) &&  // mod/rm (4,reg,0) means sib → reg
-    //   0045 == p[4] &&           // sib (5,4,0) → (rbp,rsp,0) → disp32
-    //   0000 == p[5] &&           // displacement (von Neumann endian)
-    //   0000 == p[6] &&           // displacement
-    //   0000 == p[7] &&           // displacement
-    //   0000 == p[8]              // displacement
-    uint64_t w = READ64LE(p) & READ64LE("\377\373\377\307\377\377\377\377");
-    if ((w == READ64LE("\144\110\213\004\045\000\000\000") ||
-         w == READ64LE("\144\110\003\004\045\000\000\000")) &&
-        !p[8]) {
-      p[0] = 0145;  // change %fs to %gs
-      p[5] = 0x30;  // change 0 to 0x30
-      p += 9;
-    } else {
-      ++p;
-    }
-  }
-}
-```
-
-By favoring `%gs` we've now ensured friction-free compatibility for the
-APE runtime on MacOS, Linux, and FreeBSD which are all able to conform
-easily to this convention. However additional work needs to be done at
-runtime when an APE program is started on Windows, OpenBSD, and NetBSD.
-On these platforms, all executable pages must be faulted and morphed to
-fixup the TLS instructions.
-
-On OpenBSD and NetBSD, this is as simple as undoing the example
-operation above. Earlier at compile-time we turned `%fs` into `%gs`.
-Now, at runtime, `%gs` must be turned back into `%fs`. Since the
-executable is morphing itself, this is easier said than done.
-
-OpenBSD for example enforces a `W^X` invariant. Code that's executing
-can't modify itself at the same time. The way Cosmopolitan solves this
-is by defining a special part of the binary called `.text.privileged`.
-This section is aligned to page boundaries. A GNU ld linker script is
-used to ensure that code which morphs code is placed into this section,
-through the use of a header-defined cosmo-specific keyword `privileged`.
-Additionally, the `fixupobj` program is used by the Cosmo build system
-to ensure that compiled objects don't contain privileged functions that
-call non-privileged functions. Needless to say, `mprotect()` needs to be
-a privileged function, so that it can be used to disable the execute bit
-on all other parts of the executable except for the privileged section,
-thereby making it writable. Once this has been done, code can change.
-
-On Windows the displacement bytes of the TLS instruction are changed to
-use the `%gs:0x1480+i*8` ABI where `i` is a number assigned by the WIN32
-`TlsAlloc()` API. This avoids the need to call `TlsGetValue()` which is
-implemented this exact same way under the hood. Even though 0x1480 isn't
-explicitly documented by MSDN, this ABI is believed to be stable because
-MSVC generates binaries that use this offset directly. The only caveat
-is that `TlsAlloc()` must be called as early in the runtime init as
-possible, to ensure an index less than 64 is returned.
-
-### Thread Information Block (TIB)
-
-The Actually Portable Executable Thread Information Block (TIB) is
-defined by this version of the specification as follows:
-
-- The 64-bit TIB self-pointer is stored at offset 0x00.
-- The 64-bit TIB self-pointer is also stored at offset 0x30.
-- The 32-bit `errno` value is stored at offset 0x3c.
-
-All other parts of the thread information block should be considered
-unspecified and therefore reserved for future specifications.
-
-The APE thread information block is aligned on a 64-byte boundary.
-
-Cosmopolitan Libc v3.5.8 (c. 2024-07-21) currently implements a thread
-information block that's 512 bytes in size.
-
-### Foreign Function Calls
-
-Even though APE programs always use the System V ABI, there arises the
-occasional need to interface with foreign functions, e.g. WIN32. The
-`__attribute__((__ms_abi__))` annotation introduced by GCC v6 is used
-for this purpose.
-
-The ability to change a function's ABI on a case-by-case basis is
-surprisingly enough supported by GCC, Clang, NVCC, and even the AMD HIP
-compilers for both UNIX systems and Windows. All of these compilers
-support both the System V ABI and the Microsoft x64 ABI.
-
-APE binaries will actually favor the Microsoft ABI even when running on
-UNIX OSes for certain dlopen() use-cases. For example, if we control the
-code to a CUDA module, which we compile on each OS separately from our
-main APE binary, then any function that's inside the APE binary whose
-pointer may be passed into a foreign module SHOULD be compiled to use
-the Microsoft ABI. This is because in practice the OS-specific module
-may need to be compiled by MSVC, where MS ABI is the *only* ABI, which
-forces our UNIX programs to partially conform. Thankfully, all UNIX
-compilers support doing it on a case-by-case basis.
-
-### Char Signedness
-
-Actually Portable Executable defines `char` as signed.
-
-Therefore conformant APE software MUST use `-fsigned-char` when building
-code for aarch64, as well as any other architecture that (unlike x86-64)
-would otherwise define `char` as being `unsigned char` by default.
-
-This decision was one of the cases where it made sense to offer a more
-consistent runtime experience for fat multi-arch binaries. However you
-SHOULD still write code to assume `char` can go either way. But if all
-you care about is using APE, then you CAN assume `char` is signed.
-
-### Long Double
-
-On AMD64 platforms, APE binaries define `long double` as 80-bit.
-
-On ARM64 platforms, APE binaries define `long double` as 128-bit.
-
-We accept inconsistency in this case, because hardware acceleration is
-far more valuable than stylistic consistency in the case of mathematics.
-
-One challenge arises on AMD64 for supporting `long double` across OSes.
-Unlike UNIX systems, the Windows Executive on x86-64 initializes the x87
-FPU to have double (64-bit) precision rather than 80-bit. That's because
-code compiled by MSVC treats `long double` as though it were `double` to
-prefer always using the more modern SSE instructions. However System V
-requires genuine 80-bit `long double` support on AMD64.
-
-Therefore, if an APE program detects that it's been started on a Windows
-x86-64 system, then it SHOULD use the following assembly to initialize
-the x87 FPU in System V ABI mode.
-
-```asm

-## Executable File Alignment
-
-Actually Portable Executable is a statically-linked flat executable file
-format that is, as a thing in itself, agnostic to file alignments. For
-example, the shell script payload at the beginning of the file and its
-statements have no such requirements. Alignment requirements are however
-imposed by the executable formats that APE wraps.
-
-1. ELF requires that file offsets be congruent with virtual addresses
-   modulo the CPU page size. So when we add a shell script to the start
-   of an executable, we need to round up to the page size in order to
-   maintain ELF's invariant. Although no such roundup is required on the
-   program segments once the invariant is restored. ELF loaders will
-   happily map program headers from arbitrary file intervals (which may
-   overlap) onto arbitrarily virtual intervals (which don't need to be
-   contiguous). In order to do that, the loaders will generally use
-   UNIX's mmap() function which is more restrictive and only accepts
-   addresses and offsets that are page aligned. To make it possible to
-   map an unaligned ELF program header that could potentially start and
-   stop at any byte, ELF loaders round-out the intervals, which means
-   adjacent unrelated data might also get mapped, which may need to be
-   explicitly zero'd. Thanks to the cleverness of ELF, it's possible to
-   have an executable file be very tiny, without needing any alignment
-   bytes, and it'll be loaded into a properly aligned virtual space
-   where segments can be as sparse as we want them to be.
-
-2. PE doesn't care about congruence and instead defines two separate
-   kinds of alignment. First, PE requires that the layout of segment
-   memory inside the file be aligned on at minimum the classic 512 byte
-   MS-DOS page size. This means that, unlike ELF, some alignment padding
-   may need to be encoded into the file, making it slightly larger. Next
-   PE imposes an alignment restriction on segments once they've been
-   mapped into the virtual address space, which must be rounded to the
-   system page size. Like ELF, PE segments need to be properly ordered
-   but they're allowed to drift apart once mapped in a non-contiguous
-   sparsely mapped way. When inserting shell script content at the start
-   of a PE file, the most problematic thing is the need to round up to
-   the 64kb system granularity, which results in a lot of needless bytes
-   of padding being inserted by a naive second-pass linker.
-
-3. Apple's Mach-O format is the strictest of them all. While both ELF
-   and PE are defined in such a way that invites great creativity, XNU
-   will simply refuse to an executable that does anything creative with
-   alignment. All loaded segments need to both start and end on a page
-   aligned address. XNU also wants segments to be contiguous similar to
-   portable executable, except it applies to both the file and virtual
-   spaces, which must follow the same structure.
-
-Actually Portable Executables must conform to the strictest requirements
-demanded by the support vector. Therefore an APE binary that has headers
-for all three of the above executable formats MUST conform to the Apple
-way of doing things. GNU ld linker scripts aren't very good at producing
-ELF binaries that rigidly conform to this simple naive layout. There are
-so many ways things can go wrong, where third party code might slip its
-own custom section name in-between the linker script sections that are
-explicitly defined, thereby causing ELF's powerful features to manifest
-and the resulting content overlapping. The best `ld` flag that helps is
-`--orphan-handling=error` which can help with explaining such mysteries.
-
-While Cosmopolitan was originally defined to just use stock GNU tools,
-this proved intractable over time, and the project has been evolving in
-the direction of building its own. Inventing the `apelink` program was
-what enabled the project to achieve multi-architecture binaries whereas
-previously it was only possible to do multi-OS binaries. In the future,
-our hope is that a fast power linker like Mold can be adapted to produce
-fat APE binaries directly from object files in one pass.
-
-## Position Independent Code
-
-APE doesn't currently support position independent executable formats.
-This is because APE was originally written for the GNU linker, where PIC
-and PIE were after-thoughts and never fully incorporated with the older
-more powerful linker script techniques upon which APE relies. Future
-iterations of this specification are intended to converge on modern
-standards, as our tooling becomes developed enough to support it.
-
-However this only applies to the wrapped executable formats themselves.
-While our convention to date has been to always load ELF programs at the
-4mb mark, this is not guaranteed across OSes and architectures. Programs
-should have no expectations that a program will be loaded to any given
-address. For example, Cosmo currently implements APE on AARCH64 as
-loading executables to a starting address of 0x000800000000. This
-address occupies a sweet spot of requirements.
-
-## Address Space
-
-In order to create a single binary that supports as many platforms as
-possible without needing to be recompiled, there's a very narrow range
-of addresses that can be used. That range is somewhere between 32 bits
-and 39 bits.
-
-- Embedded devices that claim to be 64-bit will oftentimes only support
-  a virtual address space that's 39 bits in size.
-
-- We can't load executable images on AARCH64 beneath 0x100000000 (4gb)
-  because Apple forbids doing that, possibly in an effort to enforce a
-  best practice for spotting 32-bit to 64-bit transition bugs. Please
-  note that this restriction only applies to Apple ARM64 systems. The
-  x86-64 version of XNU will happily load APE binaries to 0x00400000.
-
-- The AMD64 architecture on desktops and servers can usually be counted
-  upon to provide a 47-bit address space. The Linux Kernel for instance
-  grants each userspace program full dominion over addresses 0x00200000
-  through 0x00007fffffffffff provided the hardware supports this. On
-  modern workstations supporting Intel and AMD's new PML5T feature which
-  virtualizes memory using a radix trie that's five layers deep, Linux
-  is able to offer userspace its choice of fixed addresses from
-  0x00200000 through 0x00ffffffffffffff. The only exception to this rule
-  we've encountered so far is that Windows 7 and Windows Vista behaved
-  similar to embedded devices in reducing the number of va bits.
-
-## Page Size
-
-APE software MUST be page size agnostic. For many years the industry had
-converged on a strong consensus of having a page size that's 4096 bytes.
-However this convention was never guaranteed. New computers have become
-extremely popular, such as Apple Silicon, that use a 16kb page size.
-
-By convention, Cosmopolitan Libc currently generates ELF headers for
-x86-64 that are strictly aligned on a 4096-byte page size. On ARM64
-Cosmopolitan is currently implemented to always generate ELF headers
-aligned on a 16kb page size.
-
-In addition to being page size agnostic, APE software that cares about
-working correctly on Windows needs to be aware of the concept of
-allocation granularity. While the page size on Windows is generally 4kb
-in size, memory mappings can only be created on addresses that aligned
-to the system allocation granularity, which is generally 64kb. If you
-use a function like mmap() with Cosmopolitan Libc, then the `addr` and
-`offset` parameters need to be aligned to `sysconf(_SC_GRANSIZE)` or
-else your software won't work on Windows. Windows has other limitations
-too, such as lacking the ability to carve or punch holes in mappings.

-# LOCAL UNIT TESTS
-#
-# We always run unit tests as part of the normal `make` invocation. you
-# may override the $(TESTARGS) variable to do things such as enable the
-# benchmarking feature. For example:
-#
-#     TESTARGS = -b
-#
-# May be specified in your ~/.cosmo.mk file. You can also use this to
-# enable things like function tracing. For example:
-#
-#     TESTARGS = ----ftrace
-#     .PLEDGE += prot_exec
-#
-# You could then run a command like:
-#
-#     make -j8 o//test/libc/calls/openbsd_test.runs
-#
-# You need PROT_EXEC permission since ftrace morphs the binary. It's
-# also worth mentioning that the pledge command can simulate what
-# Landlock Make does:
-#
-#     o//tool/build/pledge \
-#       -v. -p 'stdio rpath wpath cpath tty prot_exec' \
-#       o//test/libc/calls/openbsd_test \
-#       ----ftrace
-#
-# This is useful in the event a test binary should run by itself, but
-# fails to run beneath Landlock Make. It's also useful sometimes to
-# override the verbosity when running tests:
-#
-#     make V=5 TESTARGS=-b o//test/libc/calls/openbsd_test.runs
-#
-# This way, if for some reason a test should fail but calls exit(0),
-# then the stdout/stderr output, which would normally be suppressed,
-# will actually be displayed.

 DETAILS
 
-  Your system has probably been configured to use binfmt_misc. You need

-  to run the command below to install /usr/bin/ape and register it with
+  Normal behavior is non-ELF files with x bit are run by /bin/sh.
-  binfmt_misc. See ape/loader.c for source code, and technical details.
+  Linux lets people globally define arbitrary magic interpreters.
+  Your computer couldve been tuned to run MZ scripts inside WINE.
+  So if you use binfmt_misc you need to explicitly register this.

+  sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register"
-
-NOTES
-
-  If it still doesn't work, possibly due to an overly aggressive WINE
-  or WSL registration, or possibly due to the ordering of definitions,
-  then one troubleshooting step is to just unregister everything using
-  sudo sh -c 'echo -1 >/proc/sys/fs/binfmt_misc/status' and try again.
