Static init inliner is using typecheck.EvalConst to handle string
concatenation expressions. But static init inliner may reveal constant
expressions after substitution, and the compiler needs to evaluate those
expressions in non-constant semantic. Using typecheck.EvalConst, which
always evaluates expressions in constant semantic, is not the right
choice.
For safety, this CL fold the logic to handle string concatenation to
static init inliner, so there won't be regression in handling constant
expressions in non-constant semantic. And also, future CL can simplify
typecheck.EvalConst logic.

For #57001, enforce the go line as declaring the minimum required
version of Go that can compile a module.
Modules that maintain compatibility with old versions of Go
but want to make use of new features in //go:build-constrained files
will be able to do so: the //go:build constraint will be interpreted
as changing the minimum Go version for that file and will unlock
the Go features allowed in that version.

For #57001, compilers and others tools will need to understand that
a different Go version can be used in different files in a program,
according to the //go:build lines in those files.
Update go/types and cmd/compile/internal/types2 to track and
use per-file Go versions. The two must be updated together because
of the files in go/types that are generated from files in types2.
The effect of the //go:build go1.N line depends on the Go version
declared in the 'go 1.M' line in go.mod. If N > M, the file gets go1.N
semantics when built with a Go 1.N or later toolchain
(when built with an earlier toolchain the //go:build line will keep
the file from being built at all).
If N < M, then in general we want the file to get go1.N semantics
as well, meaning later features are disabled. However, older Go 1.M
did not apply this kind of downgrade, so for compatibility, N < M
only has an effect when M >= 21, meaning when using semantics
from Go 1.21 or later.

compiler code and the standard library are updated because the new
restrictions require modifying the use of go:wasmimport in the

In preparation of enabling packages outside of the standard library
to use the go:wasmimport directive, the error messages are modified

tparamIndex returns the index of a type parameter given the type
parameter and a list of type parameters. If an index >= 0 is returned,
it is the index assigned to the type parameter (TypeParam.index), and
the index of the type parameter in the provided list of parameters.
For it to work correctly, the type parameter list must be from a single
type parameter declaration.
To allow for lists of arbitrary type parameters (from different generic
signatures), change the implementation to do a linear search. The result
is the index of the type parameter in the provided type parameter list,
which may be different from the index assigned to the type parameter.
The linear search is likely fast enough since type parameter lists tend
to be very short.

Due to a missing "&& !alias" check, the unified linker was treating
type aliases the same as defined types for the purpose of exporting
method bodies. The methods will get exported anyway alongside the
aliased type, so this mistake is normally harmless.
However, if multiple type aliases instantiated the same generic type
but with different type arguments, this could result in the
same (generic) method body being exported multiple times under
different symbol names. Further, because bodies aren't expected to be
exported multiple times, we were sorting them simply based on index.
And consequently, the sort wasn't total and is sensitive to the map
iteration order used while ranging over linker.bodies.
The fix is simply to add the missing "&& !alias" check, so that we
don't end up with duplicate bodies in the first place.
Thanks rsc@ for providing a minimal repro case.

Before slog.SetDefault is called the first time, calls to slog's
default Logger invoke log's default Logger.
Originally, this was done by calling log.Output. This caused source
line information to be wrong sometimes, because log.Output requires a
call depth and the code invoking it could not know how many calls were
between it and the original logging call (slog.Info, etc.). The line
information would be right if the default handler was called directly,
but wrong if it was wrapped by another handler. The handler has the pc
of the logging call, but it couldn't give that pc to the log package.
This CL fixes the problem by adding a function in the log package
that uses the pc instead of a call depth, and making that function
available to slog.
The simplest way to add pc functionality to the log package is to add
a pc argument to Logger.output, which uses it only if it's not zero.
To make that function visible to slog without exporting it, we store
the function in a variable that lives in the new log/internal package.

This also removes a racy Parallel call I added in CL 476036, which was
flagged by the race detector in the duplicate-suppression check.
(I hadn't considered the potential interaction with the leak checker.)
For #59526.
Updates #56421.

This CL adds support for os.File.Chdir() on Windows by implementing
syscall.Fchdir, which is internally used by Chdir.
Windows does not provide a function that sets the working directory
using a file handle, so we have to fallback to retrieving the file
handle path and then use it in SetCurrentDirectory.

Pull in CL 483375. This also updates golang.org/x/sys to v0.7.0 and thus
we also need to update it to that version in cmd to keep
TestDependencyVersionsConsistent happy.

We want to enable others to reproduce the exact distribution archives
we are serving on go.dev/dl. Today the code for building those
archives lives in golang.org/x/build, which is fundamentally tied to
running on the Go team build infrastructure and not easy for others to
run. This CL adds a new flag -distpack to cmd/dist, usually invoked as
make.bash -distpack, to build the distribution archives using code in
the main repository that anyone can run. Starting in Go 1.21,
the Go team build infrastructure will run this instead of its current
custom code to build those archives.
The current builds are not reproducible even given identical
infrastructure, because the archives are stamped with the current
time. It is helpful to have a timestamp in the archives indicating
when the code is from, but that time needs to be reproducible.
To ensure this, the new -distpack flag extends the VERSION file to
include a time stamp, which it uses as the modification time for all
files in the archive.
The new -distpack flag is implemented by a separate program,
cmd/distpack, instead of being in cmd/dist, so that it can be compiled
by the toolchain being distributed and not the bootstrap toolchain.
Otherwise details like the exact compression algorithms might vary
from one bootstrap toolchain to another and produce non-reproducible
builds. So there is a new 'go tool distpack', but it's omitted from
the distributions themselves, just as 'go tool dist' is.
make.bash already accepts any flags for cmd/dist, including -distpack.
make.bat is less sophisticated and looks for each known flag, so this
CL adds an update to look for -distpack. The CL also changes make.bat
to accept the idiomatic Go -flagname in addition to the non-idiomatic
(for Go) --flagname. Previously it insisted on the --flag form.
I have confirmed that using make.bash -distpack produces the
identical distribution archives for windows/amd64, linux/amd64,
darwin/amd64, and darwin/arm64 whether it is run on
windows/amd64, linux/amd64, or darwin/amd64 hosts.
For #24904.

forkAndExecInChild1 func must not acquire any locks in child, because
they might have been locked at the time of the fork. This implies to
no rescheduling, no malloc calls, and no new stack segments.
So, doing a "checkptrAlignment" is bad here, because checkptr
functions added by the instrumentation could grow the stack, which
should not be done between fork and exec calls.
Hence using a Go directive "go:nocheckptr" to forkAndExecInChild1
func,so that the compiler should not do "checkptrAlignment" when
functions marked with "go:norace".
This race detection bug was caught in go 1.21 on s390x.
Running a "./race.bash" script from "go/src" directory failed and the
bug details are provided in issue link mentioned below.
