0def9d5c02 cmd/internal/obj/arm64: Enable arm64 assembler tests for cross-compiler builds
Some of the tests for the arm64 assembler are not running for
cross-compiled arm64 builds with GOARCH=arm64. This patch allows the
tests to run for all architectures and moves the test that can only run on
arm64 into its own conditionally compiled file.

Updates #44734

e8ee1dc4f9 cmd/link/internal/ld: handle "\r" in MinGW "--print-prog-name" output
Fix the "gcc --print-prog-name" output parser to handle "\r\n", not only
"\n". The MinGW compiler on Windows uses "\r\n" as line endings, causing
the existing parser to create paths like
".../x86_64-w64-mingw32/bin/ar.exe\r", which is not correct. By trimming
the "\r\n" cutset, both types of line endings are handled correctly.

Fixes #68121

44f1870666 cmd/link: handle dynamic import variables on Darwin in plugin mode
CL 501855 added support for cgo_dynamic_import variables on Darwin.
But it didn't support the plugin build mode on amd64, where the
assembler turns a direct load (R_PCREL) to a load via GOT
(R_GOTPCREL). This CL adds the support. We just need to handle
external linking mode, as this can only occur in plugin or shared
build mode, which requires external linking.

Fixes #67976.
Updates #50891.

 - remove localTmp;
 - remove newDir, replacing calls to it with t.TempDir;
 - remove repeated comments about NFS.

2. Use t.Name, t.Cleanup and t.Helper to improve newFile and simplify
   its usage. Ensure the cleanup reports all errors.

4f77a83589 internal/syscall/unix: fix UTIME_OMIT for dragonfly
CL 219638 added UTIME_OMIT values for various systems. The value for
DragonFly BSD appears to be incorrect.

The correct value is -2 (see references below), while -1 is used for
UTIME_NOW. As a result, timestamp is changed to the current time instead
of not touching. This should have been caught by the accompanying test
case, TestChtimesWithZeroTimes, but its failures are essentially skipped
on dragonfly (this is being fixed separately in a followup CL 591535).

Improve formatting while at it.

879ace1434 net/http: keep Content-Encoding in Error, add GODEBUG for ServeContent
This reverts the changes to Error from CL 571995, and adds a
GODEBUG controlling the changes to ServeContent/ServeFile/ServeFS.

The change to remove the Content-Encoding header when serving an error
breaks middleware which sets Content-Encoding: gzip and wraps a
ResponseWriter in one which compresses the response body.

This middleware already breaks when ServeContent handles a Range request.
Correct uses of ServeContent which serve pre-compressed content with
a Content-Encoding: gzip header break if we don't remove that header
when serving errors. Therefore, we keep the change to ServeContent/
ServeFile/ServeFS, but we add the ability to disable the new behavior
by setting GODEBUG=httpservecontentkeepheaders=1.

We revert the change to Error, because users who don't want to include
a Content-Encoding header in errors can simply remove the header
themselves, or not add it in the first place.

4cf2b02548 misc/ios: rework exec wrapper to only support simulator
This updates the tools used to execute Go binaries on the Apple iOS
Simulator to (a) work with newer arm64 macOS, (b) remove support
for running binaries on physical devices, and (c) remove the reliance on
LLDB and third-party Python packages. This makes the wrapper somewhat
simpler, and easier to understand and maintain. Additionally
clangwrap.sh is updated to reflect dropping support for targeting
physical devices.

This smoothes out the path for #66360.

77cc7fbc84 doc/next: add motivation and details links for range-over-func iterators
The "Changes to the language" section at the top of the release notes
will likely ultimately include more explanation about iterators, or at
least, the Go project will likely publish additional introductory
material on iterators on the blog and so on.

As a perhaps temporary step given current interest, this CL updates the
release notes with two additional links for details and motivation.

The new package documentation for the iter package is up-to-date,
precise, and also more accessible than the language spec, while the 2022
pre-proposal GitHub discussion starts with perhaps the most compelling
motivation writeup so far. (We purposefully include "2022" in the text
to help illustrate this was not the result of an overly hasty process).

We also update the target of the existing language spec reference to be
closer to the new material.

For #61405.

8f5c6904b6 syscall: selectively update zerrors_* on openbsd/386, openbsd/arm and openbsd/amd64
The EBADMSG, ENOTRECOVERABLE, EOWNERDEAD and EPROTO Errno are missing
on openbsd/386, openbsd/arm and openbsd/amd64. These are the earliest
OpenBSD ports and they did not exist in the system headers when the
relevant zerror_* file was generated.

These exist for all other ports, hence it makes sense to add them
for consistency. Update error and signal strings so that they are
also consistent across OpenBSD ports.

a85b8810c4 cmd/go: fix problems with coverage percentage reporting w/ -coverpkg
This patch resolves a set of problems with "percent covered" metrics
reported when the "-coverpkg" is in effect; these bugs were introduced
in Go 1.22 with the rollout of CL 495452 and related changes.
Specifically, for runs with multiple packages selected but without
-coverpkg, "percent covered" metrics were generated for package P not
based just on P's statements but on the entire corpus of statements.

Fixes #65570.

whose Mode field was not "build". Update the code that constructs deps

69e7b2bcd6 go/types, types2: typecheck cases even if switch expression is invalid
Rather than returning right away when the switch expression is invalid,
continue type checking the type switch case.

The code was already written to be able to deal with an invalid switch
expression but it returned early nevertheless. Remove the early return
and rewrite the switch expression test slightly to better control the
scope of the x operand, leading to cleaner code.

In the process replace a tricky use of the x operand with a use of the
sx operand (plus guard, since sx may be nil if invalid).

Fixes #67962.

dbe03e4831 cmd/go: call telemetry.MaybeChild at start of go command
Call the new telemetry.MaybeChild function at the start of the go
command so that the child process logic can be run immediately without
running toolchain selection if this is the child process.

The Start function in the telemetry shim package has been renamed to
OpenCounters to make it clear that that's its only function.

The StartWithUpload function in the telemetry shim package has been
renamed to MaybeParent because that's its actual effective behavior in
cmd/go, the only place it's called: it won't run as the child because
MaybeChild has already been called and would have run as the child if
the program was the telemetry child, and it won't open counters because
telemetry.Start has been called. Checks are added that those functions
are always called before so that the function name and comment are
accurate.

It might make sense to add a true telemetry.MaybeParent function that
doesn't try to start the child or open counters to make things a little
simpler.

956f8a67dd internal/coverage/cfile: harden the coverage snapshot test
The existing testpoint TestCoverageSnapshot will fail if we happen to
be selecting a set of packages for inclusion in the profile that don't
include internal/coverage/cfile. Example:

 $ cd `go env GOROOT`
 $ cd src/internal/coverage
 $ go test -coverpkg=internal/coverage/decodecounter ./...
 ...
  --- FAIL: TestCoverageSnapshot (0.00s)
      ts_test.go:102: 0.276074 0.276074
      ts_test.go:104: erroneous snapshots, C1 >= C2 = true C1=0.276074 C2=0.276074

To ensure that this doesn't happen, extract the test in question out
into a separate file with a special build tag, and then have the
original testpoint do a "go test -cover -tags ... " run to make sure
that for that specific test run the cfile package is instrumented.

Fixes #67951.

7bfc82429c cmd/link: use path from "cc --print-prog-name ar" for c-archive buildmode
[This is a roll-forward of CL 479775, which had to be rolled back due
to bad interactions with the wrappers used by the ios-arm64-corellium
builder. ios-arm64-corellium is no longer being maintained AFAICT,
meaning that it should be ok to move ahead with this patch again].

When external linking with -buildmode=c-archive, the Go linker
eventually invokes the "ar" tool to create the final archive library.
Prior to this patch, if the '-extar' flag was not in use, we would
just run "ar". This works well in most cases but breaks down if we're
doing cross-compilation targeting Windows (macos system "ar"
apparently doesn't create the windows symdef section correctly). To
fix the problem, capture the output of "cc --print-prog-name ar" and
invoke "ar" using the path returned by that command.

Fixes #59221.
