5dceddfe7c runtime: use channels in gcBgMarkStartWorkers
gcBgMarkStartWorkers currently starts workers one at a time, using a
note to communicate readiness back from the worker.

However, this is a pretty standard goroutine, so we can just use a
channel to communicate between the goroutines.

In addition to being conceptually simpler, using channels has the
additional advantage of coordinating with the scheduler. Notes use OS
locks and sleep the entire thread, requiring other threads to run the
other goroutines. Waiting on a channel allows the scheduler to directly
run another goroutine. When the worker sends to the channel, the
scheduler can use runnext to run gcBgMarkStartWorker immediately,
reducing latency.

We could additionally batch start all workers and then wait only once,
however this would defeate runnext switching between the workers and
gcBgMarkStartWorkers, so in a heavily loaded system, we expect the
direct switches to reduce latency.

8e02e7b26a go/types, types2: use existing case-insensitive lookup (remove TODO)
Rather than implementing a new, less complete mechanism to check
if a selector exists with different capitalization, use the
existing mechanism in lookupFieldOrMethodImpl by making it
available for internal use.

Pass foldCase parameter all the way trough to Object.sameId and
thus make it consistently available where Object.sameId is used.

From sameId, factor out samePkg functionality into stand-alone
predicate.

Do better case distinction when reporting an error for an undefined
selector expression.

Cleanup.

09ed9a6585 cmd/compile: implement float min/max in hardware for riscv64
CL 514596 adds float min/max for amd64, this CL adds it for riscv64.

The behavior of the RISC-V FMIN/FMAX instructions almost match Go's
requirements.

However according to RISCV spec 8.3 "NaN Generation and Propagation"
>> if at least one input is a signaling NaN, or if both inputs are quiet
>> NaNs, the result is the canonical NaN. If one operand is a quiet NaN
>> and the other is not a NaN, the result is the non-NaN operand.

Go using quiet NaN as NaN and according to Go spec
>> if any argument is a NaN, the result is a NaN

This requires the float min/max implementation to check whether one
of operand is qNaN before float mix/max actually execute.

This CL also fix a typo in minmax test.

This change updates the testenv tests to correctly match on future LUCI

those haven't been set up yet, but the builder names are structured and
it's clear where the modifiers will appear. Might as well set them up
now.

93f0c0b25e internal/testenv: allow "-noopt" anywhere in builder name in test
testenv's TestHasGoBuild test is supposed to allow noopt builders to not
have go build, but the pattern match is failing on the LUCI builders
where a test shard might have an additional "-test_only" suffix in the
builder name. Furthermore, in the LUCI world, "run mods" (the builder
type suffixes) are supposed to be well-defined and composable, so it
doesn't make sense to restrict "-noopt" to the builder suffix anyway.

This change modifies the test to allow "-noopt" to appear anywhere in
the builder name when checking if it's running on a noopt builder.

e85968670e go/types, types2: better error msg when type inference fails in a call
In Checker.infer, report an error through an (incoming) *error_
so that the error can be reported as desired where infer is called.
Checker.infer is now a pure function.

Fixes #60543.

At call sites of Checker.infer, pass in an *error_ and use it to
report inference errors, together with additional information as
desired.

Fixes #60542.

In go/types, in error_.errorf, pass in a positioner rather than
a token.Pos. Also, introduce noposn, the positioner equivalent
for nopos. Adjust call sites as needed.

5000b51680 Revert "archive/tar: add FileInfoNames interface"
This reverts CL 514235. Also reverts CL 518056 which is a followup
fix.

Reason for revert: Proposal #50102 defined an interface that is
too specific to UNIX-y systems and also didn't make much sense.
The proposal is un-accepted, and we'll revisit in Go 1.23.

Fixes (via backport) #65245.
Updates #50102.

749ebaa446 net: ignore Dial errors in TestAcceptTimeout
Also use DialContext instead of just Dial so that we can ensure
the call returns before we close the listener.

The Dial in this test is intended to complete before the call to
Accept, but there is no synchronization to ensure that and sometimes
it doesn't happen. That's ok and mostly immaterial to the test, but it
does mean we need to ignore Dial errors (which can happen when the
listener is closed), and we need to be a little more careful about not
dialing a port that may have already been reused by some other test.

Fixes #65240.
Updates #17948.

66b776b025 runtime: short path for equal pointers in arm64 memequal
If memequal is invoked with the same pointers as arguments it ends up
comparing the whole memory contents, instead of just comparing the pointers.

This effectively makes an operation that could be O(1) into O(n). All the
other architectures already have this optimization in place. For
instance, arm64 also have it, in memequal_varlen.

Such optimization is very specific, one case that it will probably benefit is
programs that rely heavily on interning of strings.

Add a test that every file in api/next has corresponding
release note fragments.

Vendor in golang.org/x/build/relnote, which brings along some other

b4e7d630bc cmd/go: add GORISCV64 environment variable
The variable represents the RISC-V user-mode application profile for
which to compile.  Valid values are rva20u64 (the default) and
rva22u64.

Setting GORISCV64=rva20u64 defines the riscv64.rva20u64 build tag,
sets the internal variable buildcfg.GORISCV64 to 20 and defines the
macro GORISCV64_rva20u64 for use in assembly language code.

Setting GORISCV64=rva22u64 defines the riscv64.rva20u64 and
riscv64.rva22u64 build tags, sets the internal variable
buildcfg.GORISCV64 to 22 and defines the macro GORISCV64_rva22u64
for use in assembly language code.

This patch only provides a mechanism for the compiler and hand-coded
assembly language functions to take advantage of the RISC-V
extensions mandated by the application profiles.  Further patches
will be required to get the compiler/assembler and assembly language
functions to actually generate and use these extensions.

Fixes #61476

b3acaa8230 cmd/go/internal/str,cmd/go/internal/work: remove redundant Contains
"cmd/go/internal/str.Contains" does the same thing as the "slices.Contains".

The name "str.Contains" is also easily confused with "strings.Contains".

Given that the slices package is already used in the package,
replace "str.Contains" with "slices.Contains".

"str.Contains" is no longer used so just remove it.

1a07550962 net: unskip and attempt to deflake TestAcceptTimeout
This test has been unconditionally skipped for over five years.
It may be that whatever was causing it to flake has been fixed.
And if it hasn't been fixed, it isn't providing any value.
Let's unskip it for the Go 1.23 development cycle and see what happens.

Let's also use a separate listener for each test case, so that a
leaked Dial goroutine from one case won't interfere with the other.

Fixes #17948 (maybe).

valueInterface not copy result in the follow incorrect behavior
w1.  x := ValueOf(&v).Elem()
r1.  iface := Value.Interface()
w2.  x.Set() or x.SetT()

The write operation of W2 will be observed by the read operation of r1,
but the existing behavior is not.

The valueInterface in deepValueEqual can, in theory, pass safe==true to not copy the object,
but there is no benchmark to indicate that the memory allocation has changed,
maybe we don't actually need safe==true here.

d0dc93c8e1 runtime,internal/poll: move websocket handling out of the runtime on Windows
On Windows, the netpoll is currently coupled with the websocket usage
in the internal/poll package.

This CL moves the websocket handling out of the runtime and puts it into
the internal/poll package, which already contains most of the async I/O
logic for websockets.

This is a good refactor per se, as the Go runtime shouldn't know about
websockets. In addition, it will make it easier (in a future CL) to only
load ws2_32.dll when the Go program actually uses websockets.
