-# Building `sys/unix`
-
-The sys/unix package provides access to the raw system call interface of the
-underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
-
-Porting Go to a new architecture/OS combination or adding syscalls, types, or
-constants to an existing architecture/OS pair requires some manual effort;
-however, there are tools that automate much of the process.
-
-## Build Systems
-
-There are currently two ways we generate the necessary files. We are currently
-migrating the build system to use containers so the builds are reproducible.
-This is being done on an OS-by-OS basis. Please update this documentation as
-components of the build system change.
-
-### Old Build System (currently for `GOOS != "Linux" || GOARCH == "sparc64"`)
-
-The old build system generates the Go files based on the C header files
-present on your system. This means that files
-for a given GOOS/GOARCH pair must be generated on a system with that OS and
-architecture. This also means that the generated code can differ from system
-to system, based on differences in the header files.
-
-To avoid this, if you are using the old build system, only generate the Go
-files on an installation with unmodified header files. It is also important to
-keep track of which version of the OS the files were generated from (ex.
-Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
-and have each OS upgrade correspond to a single change.
-
-To build the files for your current OS and architecture, make sure GOOS and
-GOARCH are set correctly and run `mkall.sh`. This will generate the files for
-your specific system. Running `mkall.sh -n` shows the commands that will be run.
-
-Requirements: bash, perl, go
-
-### New Build System (currently for `GOOS == "Linux" && GOARCH != "sparc64"`)
-
-The new build system uses a Docker container to generate the go files directly
-from source checkouts of the kernel and various system libraries. This means
-that on any platform that supports Docker, all the files using the new build
-system can be generated at once, and generated files will not change based on
-what the person running the scripts has installed on their computer.
-
-The OS specific files for the new build system are located in the `${GOOS}`
-directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
-the kernel or system library updates, modify the Dockerfile at
-`${GOOS}/Dockerfile` to checkout the new release of the source.
-
-To build all the files under the new build system, you must be on an amd64/Linux
-system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
-then generate all of the files for all of the GOOS/GOARCH pairs in the new build
-system. Running `mkall.sh -n` shows the commands that will be run.
-
-Requirements: bash, perl, go, docker
-
-## Component files
-
-This section describes the various files used in the code generation process.
-It also contains instructions on how to modify these files to add a new
-architecture/OS or to add additional syscalls, types, or constants. Note that
-if you are using the new build system, the scripts cannot be called normally.
-They must be called from within the docker container.
-
-### asm files
-
-The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
-call dispatch. There are three entry points:
-```
-  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
-  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
-  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
-```
-The first and second are the standard ones; they differ only in how many
-arguments can be passed to the kernel. The third is for low-level use by the
-ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
-let it know that a system call is running.
-
-When porting Go to an new architecture/OS, this file must be implemented for
-each GOOS/GOARCH pair.
-
-### mksysnum
-
-Mksysnum is a script located at `${GOOS}/mksysnum.pl` (or `mksysnum_${GOOS}.pl`
-for the old system). This script takes in a list of header files containing the
-syscall number declarations and parses them to produce the corresponding list of
-Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
-constants.
-
-Adding new syscall numbers is mostly done by running the build on a sufficiently
-new installation of the target OS (or updating the source checkouts for the
-new build system). However, depending on the OS, you make need to update the
-parsing in mksysnum.
-
-### mksyscall.pl
-
-The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
-hand-written Go files which implement system calls (for unix, the specific OS,
-or the specific OS/Architecture pair respectively) that need special handling
-and list `//sys` comments giving prototypes for ones that can be generated.
-
-The mksyscall.pl script takes the `//sys` and `//sysnb` comments and converts
-them into syscalls. This requires the name of the prototype in the comment to
-match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
-prototype can be exported (capitalized) or not.
-
-Adding a new syscall often just requires adding a new `//sys` function prototype
-with the desired arguments and a capitalized name so it is exported. However, if
-you want the interface to the syscall to be different, often one will make an
-unexported `//sys` prototype, an then write a custom wrapper in
-`syscall_${GOOS}.go`.
-
-### types files
-
-For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
-`types_${GOOS}.go` on the old system). This file includes standard C headers and
-creates Go type aliases to the corresponding C types. The file is then fed
-through godef to get the Go compatible definitions. Finally, the generated code
-is fed though mkpost.go to format the code correctly and remove any hidden or
-private identifiers. This cleaned-up code is written to
-`ztypes_${GOOS}_${GOARCH}.go`.
-
-The hardest part about preparing this file is figuring out which headers to
-include and which symbols need to be `#define`d to get the actual data
-structures that pass through to the kernel system calls. Some C libraries
-preset alternate versions for binary compatibility and translate them on the
-way in and out of system calls, but there is almost always a `#define` that can
-get the real ones.
-See `types_darwin.go` and `linux/types.go` for examples.
-
-To add a new type, add in the necessary include statement at the top of the
-file (if it is not already there) and add in a type alias line. Note that if
-your type is significantly different on different architectures, you may need
-some `#if/#elif` macros in your include statements.
-
-### mkerrors.sh
-
-This script is used to generate the system's various constants. This doesn't
-just include the error numbers and error strings, but also the signal numbers
-an a wide variety of miscellaneous constants. The constants come from the list
-of include files in the `includes_${uname}` variable. A regex then picks out
-the desired `#define` statements, and generates the corresponding Go constants.
-The error numbers and strings are generated from `#include <errno.h>`, and the
-signal numbers and strings are generated from `#include <signal.h>`. All of
-these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
-`_errors.c`, which prints out all the constants.
-
-To add a constant, add the header that includes it to the appropriate variable.
-Then, edit the regex (if necessary) to match the desired constant. Avoid making
-the regex too broad to avoid matching unintended constants.
-
-
-## Generated files
-
-### `zerror_${GOOS}_${GOARCH}.go`
-

-signal numbers, and constants. Generated by `mkerrors.sh` (see above).

-Generated by `mksyscall.pl` (see above).
-
-### `zsysnum_${GOOS}_${GOARCH}.go`
-
-A list of numeric constants for all the syscall number of the specific GOOS
-and GOARCH. Generated by mksysnum (see above).
-
-### `ztypes_${GOOS}_${GOARCH}.go`
