111ab75432 log/slog: use atomic.Pointer instead of atomic.Value
There is no need to use atomic.Value, atomic.Pointer should also
be more performant here.

eaae2d45c7 cmd: simplify some handling of package paths
We have obj.Link.Pkgpath, so we don't need to pass it redundantly in
places where we already have an *obj.Link.

Also, renaming the parser's "compilingRuntime" field to "allowABI", to
match the "AllowAsmABI" name used by objabi.LookupPkgSpecial.

Finally, push the handling of GOEXPERIMENT_* flags up to cmd/asm's
main entry point, by simply appending them to flags.D.

f7a87e3299 runtime: fix bp restoration in panic recovery for arm64
Previously, the frame pointer wouldn't be restored at all, which could
cause panics during frame pointer unwinding. As of CL 516157, the frame
pointer is restored, but it's restored incorrectly on arm64: on arm64,
the frame pointer points one word below SP, but here it's one below
panic.fp which is the stack pointer of the caller's frame (nothing to do
with the architectural bp).

For #61766.

19e2e3c291 cmd/internal/obj/arm64: avoid unnecessary pool literal usage for load/store pairs
Implement better classification for load and store pair operations. This in
turn allows us to avoid using pool literals when the offset fits in a 24 bit
unsigned immediate. In this case, the offset can be calculated using two
add immediate instructions, rather than loading the offset from the pool
literal and then adding the offset to the base register. This requires the
same number of instructions, however avoids a load from memory and does
not require the offset to be stored in the literal pool.

Updates #59615

9a1136a654 crypto/internal/edwards25519: shorten quick.Check tests in short mode
The edwards25519 tests can be quite slow on platforms without a
well-optimized implementation, especially if the race detector is also
enabled. Since these tests aren't checking for specific inputs anyway,
the extra coverage of a more aggressive quick.Config does not seem
worth wasting extra time on slow CI builders and TryBots.

For #60109.

faf564644d go/scanner: give specific error for curvy “abc” quotes
Code examples sometimes mistakenly use curvy quotes,
leading to hard-to-spot invalid token errors.
This change makes the error message explicit.

(An alternative change would be to accept them in place
of "abc" and emit an error, but the extra check would
likely add an unacceptable dynamic cost to string scanning.)

4f97a7e6ea cmd/compile/internal/ir: set Addrtaken on Canonical ONAME too
In CL 522879, I moved the logic for setting Addrtaken from typecheck's
markAddrOf and ComputeAddrtaken directly into ir.NewAddrExpr. However,
I took the logic from markAddrOf, and failed to notice that
ComputeAddrtaken also set Addrtaken on the canonical ONAME.

The result is that if the only address-of expressions were within a
function literal, the canonical variable never got marked Addrtaken.
In turn, this could cause the consistency check in ir.Reassigned to
fail. (Yay for consistency checks turning mistakes into ICEs, rather
than miscompilation.)

Fixes #62313.

Setting LD_LIBRARY_PATH when running "go test" for a package that uses
SWIG dates back to the initial introduction of SWIG support in
CL 5845071 in 2012. Back then SWIG worked by creating a shared library,
but in CL 6851 in 2015 we changed SWIG to generate cgo input files,
and no shared library was used. Since we no longer use a shared library,
we no longer need to set LD_LIBRARY_PATH.

e92c0f846c crypto/tls: QUIC: fix panics when processing post-handshake messages
The check for fragmentary post-handshake messages in QUICConn.HandleData
was reversed, resulting in a potential panic when HandleData receives
a partial message.

In addition, HandleData wasn't checking the size of buffered
post-handshake messages. Produce an error when a post-handshake
message is larger than maxHandshake.

TestQUICConnectionState was using an onHandleCryptoData hook
in runTestQUICConnection that was never being called.
(I think it was inadvertently removed at some point while
the CL was in review.) Fix this test while making the hook
more general.

This CL can and should be reverted once that issue is fixed properly.

24b9ef1a73 cmd/cgo: add #cgo noescape/nocallback annotations
When passing pointers of Go objects from Go to C, the cgo command generate _Cgo_use(pN) for the unsafe.Pointer type arguments, so that the Go compiler will escape these object to heap.

Since the C function may callback to Go, then the Go stack might grow/shrink, that means the pointers that the C function have will be invalid.

After adding the #cgo noescape annotation for a C function, the cgo command won't generate _Cgo_use(pN), and the Go compiler won't force the object escape to heap.

After adding the #cgo nocallback annotation for a C function, which means the C function won't callback to Go, if it do callback to Go, the Go process will crash.

92bbecc518 net/http: deflake TestRequestBodyLimit
This test can return with a Transport still processing
an in-flight request, resulting in a test failure due
to the leaked Transport.

Avoid this by waiting for the Transport to close the
request body before returning.

Fixes #60264

This CL changes NewAddrExpr to require its operand to always be
typechecked, so it can return an appropriately typechecked node and
mark Addrtaken as appropriate in the process.

b036d7e17f cmd/compile/internal/noder: avoid ir.Node temps in FixValue
Instead of constructing an untyped basic literal IR node, having
typecheck convert it and return a new one, only to extract the
constant.Value; just have typecheck export the underlying value
conversion function, so we can call it directly.

99ea5b9765 cmd/compile: remove ErrorfVers and base.Flag.Lang hack
ErrorfVers used to be used by typecheck to report when new language
functionality was used, but the -lang flag (from go.mod) was set to an
older version. However, all of the callers have been since removed,
now that this is handled by types2.

And for the same reason, we can stop changing base.Flag.Lang. This was
previously a workaround so that the unified frontend could generate
arbitrary IR without upsetting typecheck, at a time when typecheck was
itself a real frontend. Now it's just a glorified desugaring pass.

3b4d428ca0 encoding/json: modernize tests
There are no changes to what is being tested.
No test cases were removed or added.

Changes made:
* Use a local implementation of test case position marking. See #52751.
* Use consistent names for all test tables and variables.
* Generally speaking, follow modern Go style guide for tests.
* Move global tables local to the test function if possible.
* Make every table entry run in a distinct testing.T.Run.

The purpose of this change is to make it easier to perform
v1-to-v2 development where we want v2 to support close to
bug-for-bug compatibility when running in v1 mode.

Annotating each test case with the location of the test data
makes it easier to jump directly to the test data itself
and understand why this particular case is failing.

Having every test case run in its own t.Run makes it easier
to isolate a particular failing test and work on fixing the code
until that test case starts to pass again.

Unfortunately, many tests are annotated with an empty name.
An empty name is better than nothing, since the testing framework
auto assigns a numeric ID for duplicate names.
It is not worth the trouble to give descriptive names to each
of the thousands of test cases.

0a17b2c174 cmd/internal/obj/arm64: load large constants into vector registers from rodata
Load large constants into vector registers from rodata, instead of placing them
in the literal pool. This treats VMOVQ/VMOVD/VMOVS the same as FMOVD/FMOVS and
makes use of the existing mechanism for storing values in rodata. Two additional
instructions are required for a load, however these instructions are used
infrequently and already have a high latency.
