This benchmark is added to test improvements in memclr_amd64.
As it is stated in Intel Optimization Manual 15.16.3.3, AVX2-implemented
memclr can produce a skewed result with the branch predictor being
trained by the large loop iteration count.
This benchmark generates sizes between some specified range. This should
help to measure how memclr works when branch predictors may be incorrectly
trained.

Make sure that all the targets of 64-bit atomic operations
are actually aligned to 8 bytes. This has been a source of
bugs on 32-bit systems. (e.g. CL 399754)
The strategy is to have a simple test that just checks the
alignment of some explicitly listed fields and global variables.
Then there's a more complicated test that makes sure the list
used in the simple test is exhaustive. That test has some
limitations, but it should catch most cases, particularly new
uses of atomic operations on new or existing fields.
Unlike a runtime assert, this check is free and will catch
accesses that occur even in very unlikely code paths.

The "simplify" feature used go/ast's object tracking in only one place -
to replace s[a:len(s)] with s[a:].
Using go/ast.Object did allow us to not simplify code like:
len := func(s []int) int { ... }
s = s[a:len(s)]
The existing code already noted the limitation with that approach,
such as "len" being redeclared in a different file in the same package.
Since go/ast's object tracking is file-based and very basic,
it wouldn't work with edge cases like those.
The reasoning is that redeclaring len and abusing it that way is
extremely unlikely, and hasn't been a problem in about a decade now.
I reason that the same applies to len being redeclared in the same file,
so we should be able to safely remove the use of go/ast.Object here.
Per https://go.dev/cl/401454, this makes "gofmt -s" about 5% faster.
If we ever wanted to truly get rid of false positive simplifications,
I imagine we'd want to reimplement the feature under go/analysis,
which is able to fully typecheck packages and suggest edits.
That seems unnecessary at this point, but we can always course correct
in the presumably unlikely scenario that users start reporting bugs.
See #46485.

Because both of these traces are printing stats from the previous cycle

The fix for #19534 (in CL 40994) adjusted escaping in the
dynamically-linked name lookup logic for the plugin package. However,
the regression test added for it incorrectly included quotes within
the -ldflags flag, causing the flag to inadvertently be ignored.
Possibly in that same CL or possibly at some other point, the
condition that the test thought it was checking stopped working: the
dynamic lookup used the path passed to ldflags, but the object file
actually contained the symbol indexed by the original package name.
Ideally we should stop mucking around with ldflags in this test and
run 'go build' from a suitably-named directory instead, to mimic the
actual conditions in which the original bug was reported. For now, as
a more targeted fix, we can pass the '-p' flag to the compiler to
adjust the package path used at compile time to match the one that
will be set at link time.

The test checks that the scheduling of the goroutines are within
a small factor, to ensure the scheduler handing off the P
correctly. There have been flaky failures on the builder (probably
due to OS scheduling delays). Increase the threshold to make it
less flaky. The gap would be much bigger if the scheduler doesn't
work correctly.
For the long term maybe it is better to test it more directly
with the scheduler, e.g. with scheduler instrumentation.
May fix#52207.

As required by RFC 8446, section 4.6.1, ticket_age_add now holds a
random 32-bit value. Before this change, this value was always set
to 0.
This change also documents the reasoning for always setting
ticket_nonce to 0. The value ticket_nonce must be unique per
connection, but we only ever send one ticket per connection.

A composite literal assignment
x = T{field: v}
may be compiled to
x = T{}
x.field = v
We already do not use this form is RHS uses LHS. If LHS is
address-taken, RHS may uses LHS implicitly, e.g.
v = &x.field
x = T{field: *v}
The lowering above would change the value of RHS (*v).

A set domain attribute in a cookie in a Set-Cookie header is intended to
create a domain cookie, i.e. a cookie that is not only sent back to the
domain the Set-Cookie was received from, but to all subdomains thereof
too. Sometimes people set this domain attribute to an IP address. This
seems to be allowed by RFC 6265 albeit it's not really sensible as there
are no "subdomains" of an IP address.
Contemporary browsers allow such cookies, currently Jar forbids them.
This CL allows to persist such cookies in the Jar and send them back
again in subsequent requests. Jar allows those cookies that all
contemporary browsers allow (not all browsers behave the same and none
seems to conform to RFC 6265 in regards to these cookies, see below).
The following browsers in current version) were tested:
- Chrome (Mac and Windows)
- Firefox (Mac and Windows)
- Safari (Mac)
- Opera (Mac)
- Edge (Windows)
- Internet Explorer (Windows)
- curl (Mac, Linux)
All of them allow a cookie to be set via the following HTTP header if
the request was made to e.g. http://35.206.97.83/ :
Set-Cookie: a=1; domain=35.206.97.83
They differ in handling a leading dot "." before the IP address as in
Set-Cookie: a=1; domain=.35.206.97.83
sets a=1 only in curl and in Internet Explorer, the other browsers just
reject such cookies.
As far as these internals can be observed the browsers do not treat such
cookies as domain cookies but as host cookies. RFC 6265 would require to
treat them as domain cookies; this is a) nonsensical and b) doesn't make
an observable difference. As we do not expose Jar entries and their
HostOnly flag it probably is still okay to claim that Jar implements a
RFC 6265 cookie jar.
RFC 6265 would allow cookies with dot-prefixed domains like
domain=.35.206.97.83 but it seems as if this feature of RFC 6265 is not
used in real life and not requested by users of package cookiejar (probably
because it doesn't work in browsers) so we refrain from documenting this
detail.

When running TestHostname, the location of the hostname binary
is hardcoded as /bin/hostname. However, on some systems the actual
location is /usr/bin/hostname.
Change this behaviour to perform a lookup for hostname in PATH,
and skip the test when it cannot be found there.

As discussed in CL 401434 there are substantial misuses of these in the
wild, and they are a potential source of unsafety even for code that
does not use them directly.
We should either keep them as-is and document when/how they can be used
safely, or deprecate them so that uses will eventually die out.
After some discussion, it was decided to deprecate them outright.
Since the docs already mentioned that they may be unstable across
releases, it should be possible to get rid of them completely later on.

In TestCgoPprofThread, the (fake) cgo traceback function pretends
all C CPU samples are in cpuHogThread. But if a profiling signal
lands in C code but outside of that thread, e.g. before/when the
thread is created, we will get a sample which looks like Go calls
into cpuHogThread. This CL makes the cgo traceback function only
return cpuHogThread PCs when a signal lands on that thread.

Historically, Objects in go/types were canonical, meaning each entity
was represented by exactly one variable and could thus be identified by
its address. With object instantiation this is no longer the case: Var
and Func objects must be copied to hold substituted type information,
and there may be more than one Var or Func variable representing the
same source-level entity.
This CL adds Origin methods to *Var and *Func, so users can efficiently
navigate to the corresponding canonical object on the generic type.
