The go command recognizes when a program named go_$GOOS_$GOARCH_exec
is in PATH. There are two such programs living in GOROOT/misc/wasm.
Like GOROOT/bin/{go,gofmt} and GOROOT/pkg/tool/**, these programs
need to have the executable bit set to do their job, so set it.
Comparing a distpack produced before and after this change shows that
the pack.go file is modified, the two go_{js,wasip1}_wasm_exec programs
have the new file mode, and there are no other changes, as expected.
The mode change is relevant to the binary and source distributions only.
No change to the module zip since it doesn't include GOROOT/misc at all,
so no effect on previously created toolchain modules whose checksums
are already recorded in the Go checksum database and cannot be changed.
(Other than by changing their "v0.0.1" version, but that's expensive.)

In racecallatomic, we do a load before calling into TSAN, so if
the address is invalid we fault on the Go stack. We currently use
a 8-byte load instruction, regardless of the data size that the
atomic operation is performed on. So if, say, we are doing a
LoadUint32 at an address that is the last 4 bytes of a memory
mapping, we may fault unexpectedly. Do a 1-byte load instead.
(Ideally we should do a load with the right size, so we fault
correctly if we're given an unaligned address for a wide load
across a page boundary. Leave that for another CL.)
Fix AMD64, ARM64, and PPC64. The code already uses 1-byte load
on S390X.
Should fix#60825.

Rather than using the external network and real-world chains for testing
the integrations with platform verifiers, use a synthetic test root.
This changes adds a constrained root and key pair to the tree, and adds
a test suite that verifies certificates issued from that root. These
tests are only executed if the root is detected in the trust store. For
reference, the script used to generate the root and key is attached to
the bottom of this commit message.
This change leaves the existing windows/darwin TestPlatformVerifier
tests in place, since the trybots do not currently have the test root in
place, and as such cannot run the suite. Once the builder images have
the root integrated, we can remove the old flaky tests, and the trybots
will begin running the new suite automatically.

The fix consist in implementing the fake network facility for udp and
unix addresses, preventing the assumed type assertion to TCPAddr from
triggering a panic. New tests are added to verify that using the fake
network from the exported functions of the net package satisfies the
minimal requirement of being able to create a listener and establish a

sort.Slice was being used to sort some newly added entries by name
to make the ctxt.Data slice reproducible, but some existing entries
have the same name, and the effect was to take the non-determinism
of the tail entries and scatter it into the earlier, deterministic section
when multiple entries had the same name.
The specific entries with the same name are type SDWARFVAR, which
all have an empty name but different relocations. If they are shuffled,
then the relocation symbols are visited in a different order, which
enters them into the string table in a different order, which results in
different object files, different object file hashes, and different build IDs
for the final executables.
Use sort.SliceStable to avoid reordering entries we don't mean to reorder.
Also add a simple test for scheduling-related non-determinism.
I debugged this originally using 'go install -race cmd/compile',
but that was slow and turned out not to be terribly reliable.
Using a few different GOMAXPROCS settings turns out to be a much more
effective (and faster) way to scramble scheduling decisions.

There is no guarantee that the user build cache will have
correct data if we are using a versioned build (with a VERSION file),
because that overrides the use of tool build IDs for staleness.
An earlier build might have run with a buggy compiler, and we don't
want those files lying around.

The go parser previously checked for invalid import paths, go/build,
seeing the parse error would put files with invalid import paths into
InvalidGoFiles. golang.org/cl/424855 removed that check from the
parser, which meant files with invalid import paths not have any parse
errors on them and not be put into InvalidGoFiles. Do a check for
invalid import paths in go/build soon after parsing so we can make
sure files with invalid import paths go into InvalidGoFiles.
This fixes an issue where the Go command assumed that if a file wasn't
invalid it had non empty import paths, leading to a panic.

To infer type arguments in an assignment of the form
var target func(t1, t2, ...) = g
where g is a generic function
func g[P1, P2, ...](p1, p2, ...)
the type checker used the synthetic function call
g(t1, t2, ...)
But because each argument (of type) t1, t2, ... is assigned to its
corresponding parameter p1, p2, ..., type inference uses assignment
rules ("inexact match") for unification.
As a result, types such as mystring and string match even though
they should not (they are not identical), yet function parameter
types must be identical to match.
This CL fixes this by constructing the synthetic call
g'(func(t1, t2, ...))
where g' is the generic function
func g'[P1, P2, ...](func(p1, p2, ...))
This mimics the function assignment directly by representing it as
a single argument passing (of a function-typed argument). Function
parameter types must now be identical to unify.
As an added benefit, the implementation is simpler.
As a consequence, when such an assignment is invalid because the
function types cannot possibly match, we now correctly get an
inference error. Without this change, in some cases unification
would succeed, only to lead to an assignment error afterwards.
While at it, update the date in the copyright notice of
testdata/manual.go so we don't need to fix it each time we copy
code from a test case in manual.go into a issueXXXXX.go file.
Fixes#60688.

Follow-up on CL 498955 which introduced a unification mode, to be used
to control the precision of unification of element types (CL 498895):
When unifying against core types of unbound type parameters, we must
use inexact unification at the top (irrespective of the unification mode),
otherwise it may fail when unifying against a defined type (core types
are always underlying types).
No specific test case (I have not been able to create one yet).
