Michael Anthony Knyszek d62154db83 weak: don't panic when calling Value on a zero Pointer
Currently weak.Pointer.Value will panic if the weak.Pointer is
uninitialized (zero value) which goes against it's documentation. Fix
this and add a test. While we're here, also add a test to ensure
weak.Make[T](nil) is equivalent to the zero value of weak.Pointer[T].

Fixes #71153.

This case is not properly handled by the type checkers (see issue)

Robert Griesemer 1d20bce981 go/types, types2: expand documentation for Info.Types map
Function types for function (and method) declarations do not
appear in Info.Types maps, only Info.Defs maps, because the
function type is implicit in the declaration and not a proper
(function) type expression. This is true even though the AST
represents these types via an (artificial) FuncType node.

Document this explicitly in the API.

No functional code changes.

Fixes #70908.

Joel Sing d8ad4af78b cmd/internal/disasm: correct instruction length handling for riscv64
disasm_riscv64 currently always returns an instruction length of four,
which is not correct if compressed instructions are in use. Return the
length of the decoded instruction, defaulting to two bytes if the
instruction is unknown.

With this change it is possible to correctly objdump a binary that is
written in C and includes compressed instructions:

$ go tool objdump ./hello

Filippo Valsorda a76cc5a4ec crypto/rsa: use λ(N) instead of φ(N)
This has no practical advantage, and requires extra variable time code,
but is an explicit FIPS 186-5 requirement.

Note that the new behavior is consistent with Go+BoringCrypto, but not
with Go 1.23. The resulting keys are essentially interchangeable, but
it's not impossible for applications to notice (google/go-tpm#383).

gcd_lcm_tests.txt is from BoringSSL.

Michael Anthony Knyszek 3f002abb60 internal/sync: add test from issue 70970
This test checks a use-case of sync.Map that's expected to be more
common in Go 1.24 and beyond, as a concurrent weak cache.

The test will also fail if CompareAndSwap is not properly atomic with
CompareAndDelete, which is what #70970 is actually about. We should have
more explicit tests checking mutual atomicity of operations, but
for now this is OK, and still useful.

For #70970.

Damien Neil f966695cce context: use "canceled" in docs to refer to timed-out contexts
In documentation, we've usually but not always referred to a
context with a closed Done channel as "done" rather than
"canceled", to avoid ambiguity between a context canceled
by calling a CancelFunc and one past its deadline.

This actually adds ambiguity, however, since it's common to
see references to a "canceled context" that are intended to
cover contexts past their deadline. If you see "function F
returns if its context is canceled", you can reasonably
assume that F will return if its context passes its
deadline, unless something says otherwise.

Update the context package docs to explicitly state that
a context is canceled when its deadline passes. Drop references
to contexts becoming "done" and just use "canceled" throughout.

Add a section on the representation of values:
distinguish between values that are self-contained
and values that contain references while avoiding
the notion of "reference types" which is misleading.

Also, use "predeclared identifier nil" rather than
"predeclared value nil" because it is the identifier
that is predeclared.

It is not true that Unmarshal always treats a JSON null
as being equivalent to a no-op.
For bools, ints, uints, floats, strings, arrays, and structs,
it treats a JSON null as a no-op. However, for []byte, slice,
map, pointer, or interface, it zeros the underlying value.

Remove this suggestion as the actual behavior is inconsistent.

Note that the proposed behavior in v2 Unmarshal is to consistently
zero out the underlying value.

Pedro Tôrres e3cd55e9d2 cmd/go/internal/work: allow @ character in some -Wl, linker flags on darwin
The GNU linker interprets @file as "read command-line options from file".
Thus, we forbid values starting with @ on linker flags. However, this
causes a problem when targeting Darwin. @executable_path, @loader_path, and
@rpath are special values used in Mach-O to change the library search path
and can be used in conjunction with the -install_name and -rpath linker
flags. Since the GNU linker does not support Mach-O, targeting Darwin
implies not using the GNU linker. Therefore, we allow @ in the linker flags
if and only if cfg.Goos == "darwin".

Cherry Mui b9955f0ad9 cmd/link, runtime: apply a delta to RODATA->DATA relocations
On AIX, an R_ADDR relocation from an RODATA symbol to a DATA
symbol does not work, as the dynamic loader can change the address
of the data section, and it is not possible to apply a dynamic
relocation to RODATA. In order to get the correct address, we
apply the delta between unrelocated and relocated data section
addresses at run time. The linker saves both the unrelocated and
the relocated addresses, so we can compute the delta.

This is possible because RODATA symbols are generated by the
compiler and so we have full control of. On AIX, the only case
is the on-demand GC pointer masks from the type descriptors, for
very large types.

Perhaps there is a better way.

Fixes #70483.
