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.

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.

Note: This CL doesn't yet plumb through the rtypes for variables that
escape to the heap. However, those rtypes are only used for calling
runtime.newobject, and the status quo as of Go 1.18 is already to use
shape rtypes for most runtime.newobject calls. (Longer term though, I
would like to get rid of shape rtypes altogether.)

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.

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.)

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:

Update the documentation to discourage use of sync.Cond, and point

help encourage behavior we want (less use of sync.Cond and more use of
channels), while also paving the way for, potentially, removing Cond

This test originally existed as two tests in test/locklinear.go, but
this checked against actual locks and was flaky. The test was checking
a property of a deep part of the runtime but from a much higher level,
and it's easy for nondeterminism due to scheduling to completely mess
that up, especially on an oversubscribed system.
That test was then moved to the sync package with a more rigorous
testing methodology, but it could still flake pretty easily.
Finally, this CL makes semtable more testable, exports it in
export_test.go, then writes a very direct scalability test for exactly
the situation the original test described. As far as I can tell, this is
much, much more stable, because it's single-threaded and is just
checking exactly the algorithm we need to check.
Don't bother trying to bring in a test that checks for O(log n) behavior
on the other kind of iteration. It'll be perpetually flaky because the
underlying data structure is a treap, so it's only _expected_ to be
O(log n), but it's very easy for it to get unlucky without a large
number of iterations that's too much for a simple test.

Unified IR records the inline nodes position right at the position of

We want to keep non-unified working up through go 1.20, thus this CL

For carrier symbols like type.*, currently we don't set its
alignment. Normally it doesn't actually matter as we still align
the inner symbols. But in some cases it does make the symbol table
a bit weird, e.g. on darwin/arm64,
0000000000070000 s _runtime.types
0000000000070001 s _type.*
The address of the symbol _type.* is a bit weird. And the new
darwin linker from Xcode 14 beta doesn't like that (see issue
53372).
This CL aligns them.

Since CL 410821 we were indexing these modules with a cache key based
on the mtimes of the files within the module. However, that seems to
be causing test failures (#53269 and maybe #53371).
In addition, indexing these modules caused a potentially-expensive
operation (re-indexing a whole module) whenever any individual file
within the module is changed, even if it isn't relevant to the
package(s) being loaded from that module. In some cases, that could
cause a significant performance regression for 'go' commands invoked
on a small subset of the packages in the module (such as running 'go
test' on a single changed package — a common case during development).
Instead, we now index only those modules found within the module cache
and within GOROOT.
In addition, we now check mtimes when indexing GOROOT modules if the
Go version begins with the string "devel ", which indicates a
non-released Go version that may include local file edits within GOROOT.
For #53371.
