-### What is the path of the package that you would like to have removed?
-
-<!---
-We can remove packages with a shared path prefix.
-For example, a request for "github.com/author" would remove all pkg.go.dev pages with that package path prefix.

-### Are you the owner of this package?
-
-<!---
-Only the package owners can request to have their packages removed from pkg.go.dev.
---->

-
-
-### What is the reason that you could not retract this package instead?
-
-<!---
-If you would like to have your module removed from pkg.go.dev, we recommend that you retract them, so that they can be removed from the go command and proxy.golang.org as well.
-
-Retracting a module version involves adding a retract directive to your go.mod file and publishing a new version. For example: https://github.com/jba/retract-demo/blob/main/go.mod#L5-L8

-See https://pkg.go.dev/about#removing-a-package for additional tips on retractions.

-### Proposal
-
-- **What is the proposed change?**
-- **Who does this proposal help, and why?**
-- **Please describe as precisely as possible the change to the language.**
-- **What would change in the language spec?**
-- **Please also describe the change informally, as in a class teaching Go.**
-- **Is this change backward compatible?**
-  - Breaking the Go 1 compatibility guarantee is a large cost and requires a large benefit.
-    Show example code before and after the change.
-  - **Before**

-- **Orthogonality: how does this change interact or overlap with existing features?**
-- **Is the goal of this change a performance improvement?**
-  - **If so, what quantifiable improvement should we expect?**
-  - **How would we measure it?**
-
-### Costs
-
-- **Would this change make Go easier or harder to learn, and why?**
-- **What is the cost of this proposal? (Every language change has a cost).**
-- **How many tools (such as vet, gopls, gofmt, goimports, etc.) would be affected?**
-- **What is the compile time cost?**
-- **What is the run time cost?**
-- **Can you describe a possible implementation?**
-- **Do you have a prototype? (This is not required.)**

+# dev.boringcrypto branch
+
+We have been working inside Google on a fork of Go that uses
+BoringCrypto (the core of [BoringSSL][]) for various crypto
+primitives, in furtherance of some [work related to FIPS 140-2][sp].
+We have heard that some external users of Go would be interested in
+this code as well, so this branch holds the patches to make Go use
+BoringCrypto.
+
+[BoringSSL]: https://boringssl.googlesource.com/boringssl/
+[sp]: https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp3678.pdf
+
+Unlike typical dev branches, we do not intend any eventual merge of
+this code into the master branch. Instead we intend to maintain in
+this branch the latest release plus BoringCrypto patches.
+
+To be clear, we are not making any statements or representations about
+the suitability of this code in relation to the FIPS 140-2 standard.
+Interested users will have to evaluate for themselves whether the code
+is useful for their own purposes.

 <p>
-Go approaches its memory model in much the same way as the rest of the language,
-aiming to keep the semantics simple, understandable, and useful.
-This section gives a general overview of the approach and should suffice for most programmers.
-The memory model is specified more formally in the next section.
+Within a single goroutine, reads and writes must behave
+as if they executed in the order specified by the program.
+That is, compilers and processors may reorder the reads and writes
+executed within a single goroutine only when the reordering
+does not change the behavior within that goroutine
+as defined by the language specification.
+Because of this reordering, the execution order observed
+by one goroutine may differ from the order perceived
+by another.  For example, if one goroutine
+executes <code>a = 1; b = 2;</code>, another might observe
+the updated value of <code>b</code> before the updated value of <code>a</code>.
 </p>
 
 <p>
-A <em>data race</em> is defined as
-a write to a memory location happening concurrently with another read or write to that same location,
-unless all the accesses involved are atomic data accesses as provided by the <code>sync/atomic</code> package.
-As noted already, programmers are strongly encouraged to use appropriate synchronization
-to avoid data races.
-In the absence of data races, Go programs behave as if all the goroutines
-were multiplexed onto a single processor.
-This property is sometimes referred to as DRF-SC: data-race-free programs
-execute in a sequentially consistent manner.
+To specify the requirements of reads and writes, we define
+<i>happens before</i>, a partial order on the execution
+of memory operations in a Go program.  If event <span class="event">e<sub>1</sub></span> happens
+before event <span class="event">e<sub>2</sub></span>, then we say that <span class="event">e<sub>2</sub></span> happens after <span class="event">e<sub>1</sub></span>.
+Also, if <span class="event">e<sub>1</sub></span> does not happen before <span class="event">e<sub>2</sub></span> and does not happen
+after <span class="event">e<sub>2</sub></span>, then we say that <span class="event">e<sub>1</sub></span> and <span class="event">e<sub>2</sub></span> happen concurrently.
+</p>
+
+<p class="rule">
+Within a single goroutine, the happens-before order is the

-While programmers should write Go programs without data races,
-there are limitations to what a Go implementation can do in response to a data race.
-An implementation may always react to a data race by reporting the race and terminating the program.
-Otherwise, each read of a single-word-sized or sub-word-sized memory location
-must observe a value actually written to that location (perhaps by a concurrent executing goroutine)
-and not yet overwritten.
-These implementation constraints make Go more like Java or JavaScript,
-in that most races have a limited number of outcomes,
-and less like C and C++, where the meaning of any program with a race
-is entirely undefined, and the compiler may do anything at all.
-Go's approach aims to make errant programs more reliable and easier to debug,
-while still insisting that races are errors and that tools can diagnose and report them.

-<h2 id="model">Memory Model</h2>
-
-<p>
-The following formal definition of Go's memory model closely follows
-the approach presented by Hans-J. Boehm and Sarita V. Adve in
-“<a href="https://www.hpl.hp.com/techreports/2008/HPL-2008-56.pdf">Foundations of the C++ Concurrency Memory Model</a>”,
-published in PLDI 2008.
-The definition of data-race-free programs and the guarantee of sequential consistency
-for race-free programs are equivalent to the ones in that work.
-</p>
-
-<p>
-The memory model describes the requirements on program executions,
-which are made up of goroutine executions,
-which in turn are made up of memory operations.
-</p>
-
-<p>
-A <i>memory operation</i> is modeled by four details:
-</p>
-<ul>
-<li>its kind, indicating whether it is an ordinary data read, an ordinary data write,
-or a <i>synchronizing operation</i> such as an atomic data access,
-a mutex operation, or a channel operation,
-<li>its location in the program,
-<li>the memory location or variable being accessed, and
-<li>the values read or written by the operation.
-</ul>
-<p>
-Some memory operations are <i>read-like</i>, including read, atomic read, mutex lock, and channel receive.
-Other memory operations are <i>write-like</i>, including write, atomic write, mutex unlock, channel send, and channel close.
-Some, such as atomic compare-and-swap, are both read-like and write-like.
-</p>
-
-<p>
-A <i>goroutine execution</i> is modeled as a set of memory operations executed by a single goroutine.
-</p>
-
-<p>
-<b>Requirement 1</b>:
-The memory operations in each goroutine must correspond to a correct sequential execution of that goroutine,
-given the values read from and written to memory.

-A Go <i>program execution</i> is modeled as a set of goroutine executions,
-together with a mapping <i>W</i> that specifies the write-like operation that each read-like operation reads from.
-(Multiple executions of the same program can have different program executions.)
-</p>
-
-<p>
-<b>Requirement 2</b>:
-For a given program execution, the mapping <i>W</i>, when limited to synchronizing operations,
-must be explainable by some implicit total order of the synchronizing operations
-that is consistent with sequencing and the values read and written by those operations.
-</p>
-
-<p>
-The <i>synchronized before</i> relation is a partial order on synchronizing memory operations,
-derived from <i>W</i>.
-If a synchronizing read-like memory operation <i>r</i>
-observes a synchronizing write-like memory operation <i>w</i>
-(that is, if <i>W</i>(<i>r</i>) = <i>w</i>),
-then <i>w</i> is synchronized before <i>r</i>.
-Informally, the synchronized before relation is a subset of the implied total order
-mentioned in the previous paragraph,
-limited to the information that <i>W</i> directly observes.
-</p>
-
-<p>
-The <i>happens before</i> relation is defined as the transitive closure of the
-union of the sequenced before and synchronized before relations.
-</p>
-
-<p>
-<b>Requirement 3</b>:
-For an ordinary (non-synchronizing) data read <i>r</i> on a memory location <i>x</i>,
-<i>W</i>(<i>r</i>) must be a write <i>w</i> that is <i>visible</i> to <i>r</i>,
-where visible means that both of the following hold:
-
 <ol>
-<li><i>w</i> happens before <i>r</i>.
-<li><i>w</i> does not happen before any other write <i>w'</i> (to <i>x</i>) that happens before <i>r</i>.
+<li><span class="event">r</span> does not happen before <span class="event">w</span>.</li>
+<li>There is no other write <span class="event">w'</span> to <code>v</code> that happens
+    after <span class="event">w</span> but before <span class="event">r</span>.</li>
 </ol>
 
 <p>
-A <i>read-write data race</i> on memory location <i>x</i>
-consists of a read-like memory operation <i>r</i> on <i>x</i>
-and a write-like memory operation <i>w</i> on <i>x</i>,
-at least one of which is non-synchronizing,
-which are unordered by happens before
-(that is, neither <i>r</i> happens before <i>w</i>
-nor <i>w</i> happens before <i>r</i>).
+To guarantee that a read <span class="event">r</span> of a variable <code>v</code> observes a
+particular write <span class="event">w</span> to <code>v</code>, ensure that <span class="event">w</span> is the only
+write <span class="event">r</span> is allowed to observe.
+That is, <span class="event">r</span> is <i>guaranteed</i> to observe <span class="event">w</span> if both of the following hold:
+</p>
+
+<ol>
+<li><span class="event">w</span> happens before <span class="event">r</span>.</li>
+<li>Any other write to the shared variable <code>v</code>
+either happens before <span class="event">w</span> or after <span class="event">r</span>.</li>
+</ol>
+
+<p>
+This pair of conditions is stronger than the first pair;
+it requires that there are no other writes happening
+concurrently with <span class="event">w</span> or <span class="event">r</span>.
 </p>
 
 <p>
-A <i>write-write data race</i> on memory location <i>x</i>
-consists of two write-like memory operations <i>w</i> and <i>w'</i> on <i>x</i>,
-at least one of which is non-synchronizing,
-which are unordered by happens before.
+Within a single goroutine,
+there is no concurrency, so the two definitions are equivalent:
+a read <span class="event">r</span> observes the value written by the most recent write <span class="event">w</span> to <code>v</code>.
+When multiple goroutines access a shared variable <code>v</code>,
+they must use synchronization events to establish
+happens-before conditions that ensure reads observe the
+desired writes.
 </p>
 
 <p>
-Note that if there are no read-write or write-write data races on memory location <i>x</i>,
-then any read <i>r</i> on <i>x</i> has only one possible <i>W</i>(<i>r</i>):
-the single <i>w</i> that immediately precedes it in the happens before order.
+The initialization of variable <code>v</code> with the zero value
+for <code>v</code>'s type behaves as a write in the memory model.
 </p>
 
 <p>
-More generally, it can be shown that any Go program that is data-race-free,
-meaning it has no program executions with read-write or write-write data races,
-can only have outcomes explained by some sequentially consistent interleaving
-of the goroutine executions.
-(The proof is the same as Section 7 of Boehm and Adve's paper cited above.)
-This property is called DRF-SC.
+Reads and writes of values larger than a single machine word
+behave as multiple machine-word-sized operations in an
+unspecified order.
 </p>
 
-<p>
-The intent of the formal definition is to match
-the DRF-SC guarantee provided to race-free programs
-by other languages, including C, C++, Java, JavaScript, Rust, and Swift.
-</p>
+<h2>Synchronization</h2>
 
-<p>
-Certain Go language operations such as goroutine creation and memory allocation
-act as synchronization operations.
-The effect of these operations on the synchronized-before partial order
-is documented in the “Synchronization” section below.
-Individual packages are responsible for providing similar documentation
-for their own operations.
-</p>
-
-<h2 id="restrictions">Implementation Restrictions for Programs Containing Data Races</h2>
-
-<p>
-The preceding section gave a formal definition of data-race-free program execution.
-This section informally describes the semantics that implementations must provide
-for programs that do contain races.
-</p>
-
-<p>
-First, any implementation can, upon detecting a data race,
-report the race and halt execution of the program.
-Implementations using ThreadSanitizer
-(accessed with “<code>go</code> <code>build</code> <code>-race</code>”)
-do exactly this.
-</p>
-
-<p>
-Otherwise, a read <i>r</i> of a memory location <i>x</i>
-that is not larger than a machine word must observe
-some write <i>w</i> such that <i>r</i> does not happen before <i>w</i>
-and there is no write <i>w'</i> such that <i>w</i> happens before <i>w'</i>
-and <i>w'</i> happens before <i>r</i>.
-That is, each read must observe a value written by a preceding or concurrent write.
-</p>
-
-<p>
-Additionally, observation of acausal and “out of thin air” writes is disallowed.
-</p>
-
-<p>
-Reads of memory locations larger than a single machine word
-are encouraged but not required to meet the same semantics
-as word-sized memory locations,
-observing a single allowed write <i>w</i>.
-For performance reasons,
-implementations may instead treat larger operations
-as a set of individual machine-word-sized operations
-in an unspecified order.
-This means that races on multiword data structures
-can lead to inconsistent values not corresponding to a single write.
-When the values depend on the consistency
-of internal (pointer, length) or (pointer, type) pairs,
-as can be the case for interface values, maps,
-slices, and strings in most Go implementations,
-such races can in turn lead to arbitrary memory corruption.

-<p>
-The Go memory model restricts compiler optimizations as much as it does Go programs.
-Some compiler optimizations that would be valid in single-threaded programs are not valid in all Go programs.
-In particular, a compiler must not introduce writes that do not exist in the original program,
-it must not allow a single read to observe multiple values,
-and it must not allow a single write to write multiple values.
-</p>
-
-<p>
-All the following examples assume that `*p` and `*q` refer to
-memory locations accessible to multiple goroutines.
-</p>
-
-<p>
-Not introducing data races into race-free programs means not moving
-writes out of conditional statements in which they appear.
-For example, a compiler must not invert the conditional in this program:
-</p>
-
-<pre>
-*p = 1
-if cond {
-	*p = 2
-}
-</pre>
-
-<p>
-That is, the compiler must not rewrite the program into this one:
-</p>
-
-<pre>
-*p = 2
-if !cond {
-	*p = 1
-}
-</pre>
-
-<p>
-If <code>cond</code> is false and another goroutine is reading <code>*p</code>,
-then in the original program, the other goroutine can only observe any prior value of <code>*p</code> and <code>1</code>.
-In the rewritten program, the other goroutine can observe <code>2</code>, which was previously impossible.
-</p>
-
-<p>
-Not introducing data races also means not assuming that loops terminate.
-For example, a compiler must in general not move the accesses to <code>*p</code> or <code>*q</code>
-ahead of the loop in this program:
-</p>
-
-<pre>
-n := 0
-for e := list; e != nil; e = e.next {
-	n++
-}
-i := *p
-*q = 1
-</pre>
-
-<p>
-If <code>list</code> pointed to a cyclic list,
-then the original program would never access <code>*p</code> or <code>*q</code>,
-but the rewritten program would.
-(Moving `*p` ahead would be safe if the compiler can prove `*p` will not panic;
-moving `*q` ahead would also require the compiler proving that no other
-goroutine can access `*q`.)
-</p>
-
-<p>
-Not introducing data races also means not assuming that called functions
-always return or are free of synchronization operations.
-For example, a compiler must not move the accesses to <code>*p</code> or <code>*q</code>
-ahead of the function call in this program
-(at least not without direct knowledge of the precise behavior of <code>f</code>):
-</p>
-
-<pre>
-f()
-i := *p
-*q = 1
-</pre>
-
-<p>
-If the call never returned, then once again the original program
-would never access <code>*p</code> or <code>*q</code>, but the rewritten program would.
-And if the call contained synchronizing operations, then the original program
-could establish happens before edges preceding the accesses
-to <code>*p</code> and <code>*q</code>, but the rewritten program would not.
-</p>
-
-<p>
-Not allowing a single read to observe multiple values means
-not reloading local variables from shared memory.
-For example, a compiler must not discard <code>i</code> and reload it
-a second time from <code>*p</code> in this program:
-</p>
-
-<pre>
-i := *p
-if i &lt; 0 || i &gt;= len(funcs) {
-	panic("invalid function index")
-}
-... complex code ...
-// compiler must NOT reload i = *p here
-funcs[i]()
-</pre>
-
-<p>
-If the complex code needs many registers, a compiler for single-threaded programs
-could discard <code>i</code> without saving a copy and then reload
-<code>i = *p</code> just before
-<code>funcs[i]()</code>.
-A Go compiler must not, because the value of <code>*p</code> may have changed.
-(Instead, the compiler could spill <code>i</code> to the stack.)
-</p>
-
-<p>
-Not allowing a single write to write multiple values also means not using
-the memory where a local variable will be written as temporary storage before the write.
-For example, a compiler must not use <code>*p</code> as temporary storage in this program:
-</p>
-
-<pre>
-*p = i + *p/2
-</pre>
-
-<p>
-That is, it must not rewrite the program into this one:
-</p>
-
-<pre>
-*p /= 2
-*p += i
-</pre>
-
-<p>
-If <code>i</code> and <code>*p</code> start equal to 2,
-the original code does <code>*p = 3</code>,
-so a racing thread can read only 2 or 3 from <code>*p</code>.
-The rewritten code does <code>*p = 1</code> and then <code>*p = 3</code>,
-allowing a racing thread to read 1 as well.
-</p>
-
-<p>
-Note that all these optimizations are permitted in C/C++ compilers:
-a Go compiler sharing a back end with a C/C++ compiler must take care
-to disable optimizations that are invalid for Go.
-</p>
-
-<p>
-Note that the prohibition on introducing data races
-does not apply if the compiler can prove that the races
-do not affect correct execution on the target platform.
-For example, on essentially all CPUs, it is valid to rewrite
-</p>
-
-<pre>
-n := 0
-for i := 0; i < m; i++ {
-	n += *shared
-}
-</pre>
-
-into:
-
-<pre>
-n := 0
-local := *shared
-for i := 0; i < m; i++ {
-	n += local
-}
-</pre>
-
-<p>
-provided it can be proved that <code>*shared</code> will not fault on access,
-because the potential added read will not affect any existing concurrent reads or writes.
-On the other hand, the rewrite would not be valid in a source-to-source translator.
-</p>
-
-<h2 id="conclusion">Conclusion</h2>
-
-<p>
-Go programmers writing data-race-free programs can rely on
-sequentially consistent execution of those programs,
-just as in essentially all other modern programming languages.
-</p>
-
-<p>
-When it comes to programs with races,
-both programmers and compilers should remember the advice:
-don't be clever.

+This directory holds build scripts for unofficial, unsupported
+distributions of Go+BoringCrypto.
+
+## Version strings
+
+The distribution name for a Go+BoringCrypto release has the form `<GoVersion>b<BoringCryptoVersion>`,
+where `<GoVersion>` is the Go version the release is based on, and `<BoringCryptoVersion>` is
+an integer that increments each time there is a new release with different BoringCrypto bits.
+The `<BoringCryptoVersion>` is stored in the `VERSION` file in this directory.
+
+For example, the first release is based on Go 1.8.3 is `go1.8.3b1`.
+If the BoringCrypto bits are updated, the next would be `go1.8.3b2`.
+If, after that, Go 1.9 is released and the same BoringCrypto code added to it,
+that would result in `go1.9b2`. There would likely not be a `go1.9b1`,
+since that would indicate Go 1.9 with the older BoringCrypto code.
+
+## Releases
+
+The `build.release` script prepares a binary release and publishes it in Google Cloud Storage
+at `gs://go-boringcrypto/`, making it available for download at
+`https://go-boringcrypto.storage.googleapis.com/<FILE>`.
+The script records each published release in the `RELEASES` file in this directory.
+
+The `build.docker` script, which must be run after `build.release`, prepares a Docker image
+and publishes it on hub.docker.com in the goboring organization.
+`go1.8.3b1` is published as `goboring/golang:1.8.3b1`.
+
+## Release process
+
+Development is done on the dev.boringcrypto branch, which tracks
+master. Releases are cut from dev.boringcrypto.go1.X branches,
+which are BoringCrypto backported to the Go 1.X release branches.
+To issue new BoringCrypto releases based on Go 1.X:
+
+1. If the BoringCrypto bits have been updated, increment the
+   number in `VERSION`, send that change out as a CL for review,
+   get it committed to dev.boringcrypto, and run `git sync`.
+
+2. Change to the dev.boringcrypto.go1.X branch and cherry-pick
+   all BoringCrypto updates, including the update of the
+   `VERSION` file. If desired, merge release-branch.go1.X into
+   dev.boringcrypto.go1.X. Mail them out and get them committed.
+
+3. **Back on the dev.boringcrypto branch**, run `git fetch`,
+   `make.bash` and then `build.release dev.boringcrypto.go1.X`.
+   The script will determine the base Go version and the
+   BoringCrypto version, build a release, and upload it.
+
+4. Run `build.docker`, which will build and upload a Docker image
+   from the latest release.
+
+5. Send out a CL with the updated `RELEASES` file and get it
+   committed to dev.boringcrypto.
+
+## Building from Docker
+
+A Dockerfile that starts with `FROM golang:1.8.3` can switch
+to `FROM goboring/golang:1.8.3b2` (see [goboring/golang on Docker Hub](https://hub.docker.com/r/goboring/golang/))
+and should need no other modifications.
+
+## Building from Bazel
+
+Starting from [bazelbuild/rules_go](https://github.com/bazelbuild/rules_go)
+tag 0.7.1, simply download the BoringCrypto-enabled Go SDK using
+`go_download_sdk()` before calling `go_register_toolchains()`.
+
+For example, to use Go 1.9.3 with BoringCrypto on Linux, use the following lines
+in `WORKSPACE`:
+```python
+load("@io_bazel_rules_go//go:def.bzl", "go_rules_dependencies", "go_download_sdk", "go_register_toolchains")
+
+go_rules_dependencies()
+
+go_download_sdk(
+    name = "go_sdk",
+    sdks = {
+       "linux_amd64": ("go1.9.3b4.linux-amd64.tar.gz", "db1997b2454a2f27669b849d2d2cafb247a55128d53da678f06cb409310d6660"),
+    },
+    urls = ["https://storage.googleapis.com/go-boringcrypto/{}"],
+)
+
+go_register_toolchains()
+```
+
+**Note**: you must *not* enable `pure` mode, since cgo must be enabled. To
+ensure that binaries are linked with BoringCrypto, you can set `pure = "off"` on
+all relevant `go_binary` rules.
+
+## Caveat
+
+BoringCrypto is used for a given build only in limited circumstances:
+
+  - The build must be GOOS=linux, GOARCH=amd64.
+  - The build must have cgo enabled.
+  - The android build tag must not be specified.
+  - The cmd_go_bootstrap build tag must not be specified.
+
+The version string reported by `runtime.Version` does not indicate that BoringCrypto
+was actually used for the build. For example, linux/386 and non-cgo linux/amd64 binaries
+will report a version of `go1.8.3b2` but not be using BoringCrypto.
+
+To check whether a given binary is using BoringCrypto, run `go tool nm` on it and check
+that it has symbols named `*_Cfunc__goboringcrypto_*`.
+
+The program [rsc.io/goversion](https://godoc.org/rsc.io/goversion) will report the
+crypto implementation used by a given binary when invoked with the `-crypto` flag.
