a42573c2f1 net: avoid darwin/arm64 platform bug in TestCloseWrite
On darwin_arm64, reading from a socket at the same time as the other
end is closing it will occasionally hang for 60 seconds before
returning ECONNRESET. (This is a macOS issue, not a Go issue.)

Work around this condition by adding a brief sleep before the read.

Fixes #49352 (we hope).
Updates #37795.

c3bea70d9b cmd/link: link against libsynchronization.a for -race on windows
As of LLVM rev 41cb504b7c4b18ac15830107431a0c1eec73a6b2, the
race detector runtime now refers to things in the windows
synchronization library, hence when doing windows internal
linking, at that library to the list of host archives that
we visit. The tsan code that makes the reference is here:

41cb504b7c/compiler-rt/lib/sanitizer_common/sanitizer_win.cpp (L48)
41cb504b7c/compiler-rt/lib/sanitizer_common/sanitizer_win.cpp (L834)

Note that libsynchronization.a is not guaranteed to be available on
all windows systems, so in the external linking case, check for its
existence before adding "-lsynchronization" to the external linker
args.

Updates #53539.

666d736ecb cmd/compile: do branch/label checks only once
The previous change implemented the missing fallthrough checking
in the parser. Therefore we can now disable the duplicate check
in the type checker:

- rename (types2.Config.)IngoreLabels to IgnoreBranches to more
  accurately reflect its functionality

- now also ignore break/continue/fallthroughs, not just labels

The IgnoreBranches flag only exists for types2, for use with
the compiler. There's no need to port this code to go/types.

Note: An alternative (and perhaps better) approach would be
to not use the the parser's CheckBranches mode and instead
enable (i.e. not disable) the branch/label checking in the
type checker. However, this requires a bit more work because
the type checker's error messages about goto's jumping over
variables don't have access to the variable names, which are
desired in the error messages.

Fixes #51456.

Follow rename of trace-internal tests from "Span" to "Region". Update

http_1_5_good behavior (about 7ms of total run time and trace file size
under 50kB).

bdab4cf47a cmd/go, cmd/link: support failure to create _cgo_import.go
For a package that uses cgo, the file _cgo_import.go is created to
record information required for internal linking: the non-Go dynamic
symbols and libraries that the package depends on. Generating this
information sometimes fails, because it can require recreating all the
dependencies of all transitively imported packages. And the
information is rarely needed, since by default we use external linking
when there are packages outside of the standard library that use cgo.

With this CL, if generating _cgo_import.go fails, we don't report an
error. Instead, we mark the package as requiring external linking, by
adding an empty file named "dynimportfail" into the generated archive.
If the linker sees a file with that name, it rejects an attempt to use
internal linking.

aca37d16a5 cmd/go: avoid indexing modules in GOROOT
Scanning GOROOT modules for changes appears to be causing Windows
builders to time out in x/tools tests. We may try a per-package index
instead, but for now just skip GOROOT modules (as we do for main
modules).

Fixes #53493.

b004c739b5 go/types, types2: fix parameter order dependence in type inference
If we have more than two function arguments to a generic function,
we may have arguments with named and unnamed types. If that is the
case, permutate params and args such that the arguments with named
types are first in the list. This way, independent of parameter
ordering, the type inference will produce the same result.

This extra step is not explicitly outlined in the spec yet but we
all agree that (parameter) order independence is an invariant that
we should uphold for type inference. As we move towards less
operational and more descriptive rules for type inference, we will
incorporate this property as well.

The actual fix for this bug existed before 1.18 but was not enabled.
This CL merely enables the fix (switches a flag) and adjusts some
tests.

Fixes #43056.

f2c7e78592 spec: document operations which accept []byte|string constrained types
Pre-1.18, as special cases, the built-in operations append and copy
accepted strings as second arguments if the first argument was a byte
slice. With Go 1.18, these two built-ins as well as slice expressions
rely on the notion of core types in their specification.

Because we want to permit slice expressions, append, and copy to
operate on (1st or 2nd operands) that are type parameters restricted
by []byte | string (and variations thereof), the simple notion of
core type is not sufficient for these three operations. (The compiler
already permits such more relaxed operations).

In the section on core types, add a paragraph and examples introducing
the (artificial) core type "bypestring", which describes the core type
of type sets whose underlying types are []byte or string. Adjust the
rules for slice expressions, append, and copy accordingly.

Also (unrelated): Adjust prose in the only paragraph where we used
personal speech ("we") to impersonal speech, to match the rest of
the spec.

Fixes #52859.

ab422f2749 runtime/trace: ignore fallback stacks in test
When runtime.sigprof encounters a stack that gentraceback is unable to
process, it synthesizes a call stack with a sentinel function (such as
runtime._System) at the leaf.

The test to confirm that runtime/trace and runtime/pprof have similar
views of CPU profile samples has trouble with those stacks. The test
confirms that the samples match by confirming that their symbolized
forms match, and the symbolization procedure is very different for the
two packages.

Skip the samples that the CPU profiler's view symbolizes to include one
of runtime.sigprof's sentinel functions at the leaf. (The test design
expects the CPU profiler to under-report samples relative to the
execution tracer.)

530511bacc cmd/go/internal/modindex: avoid walking modules when not needed
Due to a missed condition in CL 412394, we were walking all modules
(instead of just the ones contained in GOROOT) at each invocation of a
devel version of cmd/go.

Moreover, while we were running cmd/go tests, we were re-walking
GOROOT at each 'go' invocation in the test even though we expect
GOROOT to be stable within a test run.

This change always avoids walking non-GOROOT modules, and also adds a
salt (configurable via GODEBUG) and uses it to avoid walking GOROOT
modules when GOROOT is known to be stable (such as over the course of
a 'cmd/go' test run).

This should fix the cmd/go test timeouts that are currently occurring
on the dragonfly-amd64 builder, such as this one:
https://build.golang.org/log/21c01c3ae5490d387d84abeaf872b3a0a76ab8e5
