ea2c27fe82 cmd/compile: package-annotate structs when error would be ambiguous
Before emitting a "wanted Foo but got Bar" message for an interface
type match failure, check that Foo and Bar are different.  If they
are not, add package paths to first unexported struct field seen,
because that is the cause (a cause, there could be more than one).

Replicated in go/types.

Added tests to go/types and cmd/compile/internal/types2

Fixes #54258.

dccc58e1b9 cmd/go: don't report non-go files in CompiledGoFiles
We save non-go files in the cached srcfiles file because we want the

7161fc737d cmd/go/internal/script: check lack of error for non-waiting cmds
In the script engine, if a command does not return a Wait function and
it succeeds, we won't call checkStatus. That means that commands that
don't have a wait function, have a "!" indicating that they are
supposed to fail, and then succeed will spuriously not fail the script
engine test even they were supposed to fail but didn't.

e18d07ddc5 runtime: optimise memmove on riscv64
Implement a more optimised memmove on riscv64, where up to 64 bytes are moved
per loop after achieving alignment. In the unaligned case, memory is moved at
up to 8 bytes per loop.

This also avoids doing unaligned loads and stores, which results in kernel
traps and a significant performance penality.

Fixes #48248.

1ed636dc97 cmd/link/internal/ppc64: fix trampoline reuse distance calculation
If a compatible trampoline has been inserted by a previously laid
function in the same section, and is known to be sufficiently close,
it can be reused.

When testing if the trampoline can be reused, the addend of the direct
call should be ignored. It is already encoded in the trampoline. If the
addend is non-zero, and the target sufficiently far away, and just
beyond direct call reach, this may cause the trampoline to be
incorrectly reused.

This was observed on go1.17.13 and openshift-installer commit f3c53b382
building in release mode with the following error:

github.com/aliyun/alibaba-cloud-sdk-go/services/cms.(*Client).DescribeMonitoringAgentAccessKeyWithChan.func1: direct call too far: runtime.duffzero+1f0-tramp0-1 -2000078

0613418c98 cmd/internal/obj/arm64: mark branch instructions in optab
Currently, we judge whether we need to fix up the branch instruction
based on Optab.type_ field, but the type_ field in optab may change.
This CL marks the branch instruction in optab, and checks whether to
do fixing up according to the mark. Depending on the constant parameter
range of the branch instruction, there are two labels, BRANCH14BITS,
BRANCH19BITS. For the 26-bit branch, linker will handle it.

Besides this CL removes the unnecessary alignment of the DWORD
instruction. Because the ISA doesn't require it and no 64-bit load
assume it. The only effect is that there is some performance penalty
for loading from DWORDs if the 8-byte DWORD instruction crosses the
cache line, but this is very rare.

d6171c9be2 runtime: fix conflict between lfstack and checkptr
lfstack does very unsafe things. In particular, it will not
work with nodes that live on the heap. In normal use by the runtime,
that is the case (it is only used for gc work bufs). But the lfstack
test does use heap objects. It goes through some hoops to prevent
premature deallocation, but those hoops are not enough to convince
-d=checkptr that everything is ok.

Instead, allocate the test objects outside the heap, like the runtime
does for all of its lfstack usage. Remove the lifetime workaround
from the test.

1f4394a0c9 runtime: work around Apple libc bugs to make exec stop hanging
For a while now, we've had intermittent reports about problems with
os/exec on macOS, but no clear way to reproduce them. Recent changes
in the os/exec package test seem to have aligned the stars just right,
at least on my two x86 and ARM MacBook Pro laptops, to make the
package test hang with roughly 50% probability. When it does hang, the
stacks I see in the hung process match the ones reported for the
Go-based hangs in #33565. (They do not match the ones reported in the
so-called C reproducer in that issue, but I think that reproducer is
actually reproducing a different race, between fork and exit.)

The stacks obtained from the hung child processes are in
libSystem_atfork_child, which is supposed to reinitialize various
parts of the C library in the new process.

One common stack dies in _notify_fork_child calling _notify_globals
(inlined) calling _os_alloc_once, because _os_alloc_once detects that
the once lock is held by the parent process and then calls
_os_once_gate_corruption_abort. The allocation is setting up the
globals for the notification subsystem. See the source code at [1].
To work around this, we can allocate the globals earlier in the Go
program's lifetime, before any execs are involved, by calling any
notify routine that is exported, calls _notify_globals, and doesn't do
anything too expensive otherwise. notify_is_valid_token(0) fits the bill.

The other common stack dies in xpc_atfork_child calling
_objc_msgSend_uncached which ends up in
WAITING_FOR_ANOTHER_THREAD_TO_FINISH_CALLING_+initialize. Of course,
whatever thread the child is waiting for is in the parent process and
is not going to finish anything in the child process. There is no
public source code for these routines, so it is unclear exactly what
the problem is. However, xpc_atfork_child turns out to be exported
(for use by libSystem_atfork_child, which is in a different library,
so xpc_atfork_child is unlikely to be unexported any time soon).
It also stands to reason that since xpc_atfork_child is called at the
start of any forked child process, it can't be too harmful to call at
the start of an ordinary Go process. And whatever caches it needs for
a non-deadlocking fast path during exec empirically do get initialized
by calling it at startup.

This CL introduces a function osinit_hack, called at osinit time,
which calls notify_is_valid_token(0) and xpc_atfork_child().
Doing so makes the os/exec test pass reliably on both my laptops -
I can run it successfully hundreds of times in a row when my previous
record was twice in a row.

Fixes #33565.
Fixes #56784.

6e0e492e12 cmd/compile/internal/pgo: count only the last two frames as a call edge
Currently for every CPU profile sample, we apply its weight to all
call edges of the entire call stack. Frames higher up the stack
are unlikely to be repeated calls (e.g. runtime.main calling
main.main). So adding weights to call edges higher up the stack
may be not reflecting the actual call edge weights in the program.
This CL changes it to add weights to only the edge between the
last two frames.

Without a branch profile (e.g. LBR records) this is not perfect,
but seems more reasonable.

3f1bcc58b3 cmd/compile: simplify PGO hot caller/callee computation
Currently, we use CDF to compute a weight threshold and then use
the weight threshold to determine whether a call site is hot. As
when we compute the CDF we already have a list of hot call sites
that make up the given percentage of the CDF, just use that list.

Also, when computing the CDF threshold, include the very last node
that makes it to go over the threshold. (I.e. if the CDF threshold
is 50% and one hot node takes 60% of weight, we should include that
node instead of excluding it. In practice it rarely matters,
probably only for testing and micro-benchmarks.)

For implementing interface to empty interface conversion, the compiler
generate code like:

	var res *uint8
	res = itab
	if res != nil {
		res = res.type
	}

However, itab has type *uintptr, so the assignment is broken. The
problem is not shown up, until CL 450215, which call typecheck on this
broken assignment.

To fix this, just cast itab to *uint8 when doing the conversion.

5f7abeca5a cmd/compile: teach regalloc about temporary registers
Temporary registers are sometimes needed for an architecture backend
which needs to use several machine instructions to implement a single
SSA instruction.

Mark such instructions so that regalloc can reserve the temporary register
for it. That way we don't have to reserve a fixed register like we do now.

Convert the temp-register-using instructions on amd64 to use this
new mechanism. Other archs can follow as needed.

CL 450136 made the compiler to be able to handle simple inlined calls in
staticinit. However, it's missed a condition when checking substituting
arg for param. If there's any non-trivial closures, it has captured one
of the param, so the substitution could not happen.

5c834a2eb0 go/types, types2: implement type checking of "clear" built-in
Will become available with Go 1.21.

Recognizing the `clear` built-in early is not causing any problems:
if existing code defines a `clear`, that will be used as before. If
code doesn't define `clear` the error message will make it clear
that with 1.21 the function will be available. It's still possible
to define a local `clear` and get rid of the error; but more likely
the name choice should be avoided going forward, so this provides a
useful early "heads-up".

For #56351.

cafb49ac73 go/parser: allow trailing commas in embedded instantiated types
go/parser can correctly parse interfaces that instantiate and embed
generic interfaces, but not structs. This is because in the case of
structs, it does not expect RBRACK as a token trailing COMMA in the type
argument, even though it is allowed by the spec.

For example, go/parser produces an error for the type declaration below:

type A struct {
    B[byte, []byte,]
}

42d975e5fe time: avoid creating a parse error from the next chunk of the value
When it reports a parse error, it uses the "value" variable as the
value element of the parse error. Previously, in some of the cases,
the "value" variable is always updated to the next chunk of the value
to be parsed (even if an earlier chunk is invalid). The reported
parse error is confusing in this case.

This CL addresses this issue by holding the original value, and when
it fails to parse the time, use it to create the parse error.

Fixes #56730.

44edc5d787 cmd/dist: skip non-race tests
In -race mode, the dist test command only registers the std, race,
osusergo, and amd64ios tests before returning early from
(*tester).registerTests. Prior to CL 450018, the osusergo and amd64ios
tests weren't even affected by -race mode, so it seems their inclusion
was unintentional. CL 450018 lifted the logic to run tests in race
mode, which means these tests went from running without -race to
running with -race. Unfortunately, amd64ios is not compatible with
-race, so it is now failing on the darwin-amd64-race builder.

Fix this by omitting the osusergo and amd64ios tests from -race mode,
since it seems like they were really intended to be included anyway.

This should fix the darwin-amd64-race builder.

Updates #37486.

We were using a RWMutex RLock around a single memory load,
which is not a good use of a RWMutex--it introduces extra work
for the RLock but contention around a single memory load is unlikely.
And, the tryUpdate method was not acquiring the mutex anyhow.

The new atomic.Pointer type is type-safe and easy to use correctly
