0e7c9846c4 cmd: don't require build tags in relnote pathnames
Due to a bug in golang.org/x/build/relnote, API features affecting
specific builds would need to include those build tags in relnote
pathnames.

This CL vendors in the fixed golang.org/x/build. (That caused other
modules to be vendored in as well.)

It also renames the syscall relnote file to remove the build tags
from its pathname.

For #64169.

faf2a8416a internal/poll: revise the determination about [handled] and improve the code readability for SendFile
There were a bit too many conditional branches in the old code,
resulting in a poor readability. It could be more concise by reducing
and consolidating some of the conditions.

Furthermore, how we've determined whether or not the data transimission
was handled by sendfile(2) seems inappropriate, because it marked the
operation as unhandled whenever any non-retryable error occurs from
calling sendfile(2), it doesn't look like a right approach, at least
this is an inconsistent behavior with what we've done in Splice.

8a0fbd75a5 encoding/xml: reject XML declaration after start of document
The XML specification requires an XML declaration, if present, to only
appear at the very beginning of the document, not even preceded by
whitespace. The parser currently accepts it at any part of the input.

Rejecting whitespace at the beginning of the file might break too many
users. This change instead only rejects an XML declaration preceded by
a non-whitespace token *and* allows the Encoder to emit whitespace
before an XML declaration. This means that a token stream produced by
the Decoder can be passed to the Encoder without error, while we still
don't emit clearly invalid XML.

This might break programs depending on Decoder allowing arbitrary XML
before the XML declaration.

Fixes #65691.

db57e5a040 go/types, types2: remove unreachable func (minor cleanup)
In some places we can't use unreachable() because it does
not terminate control flow and we need to resort to panic.
Be consistent and just use panic("unreachable") everywhere.
This also opens the door to reporting more specific panic
messages.

Mechanical change: s/unreachable()/panic("unreachable")/

Minor cleanup for better consistency.

638b9023e3 runtime: be careful about crash FD changes during panic
There are two separate cases here:

The base case is simple: a concurrent call to SetCrashOutput while
panicking will switch the crash FD, which could cause the first half of
writes to go to the old FD, and the second half to the new FD. This
isn't a correctness problem, but would be annoying to see in practice.
Since it is easy to check for, I simply drop any changes if panicking is
already in progress.

The second case is more important: SetCrashOutput will close the old FD
after the new FD is swapped, but writeErrData has no locking around use
of the fd, so SetCrashOutput could close the FD out from under
writeErrData, causing lost writes. We handle this similarly, by not
allowing SetCrashOutput to close the old FD if a panic is in progress,
but we have to be more careful about synchronization between
writeErrData and setCrashFD to ensure that writeErrData can't observe
the old FD while setCrashFD allows close.

For #42888.

750738b5d1 os: make use of pidfd on linux
Use Process.handle field to store pidfd, and make use of it. Only use
pidfd functionality if all the needed syscalls are available.

1. StartProcess: obtain the pidfd from the kernel, if available,
   using the functionality added by CL 520266. Note we could not modify
   syscall.StartProcess to return pidfd directly because it is a public
   API and its callers do not expect it, so we have to use ensurePidfd
   and getPidfd.

2. (*Process).Kill: use pidfdSendSignal, if the syscall is available
   and pidfd is known. This is slightly more complicated than it should
   be, since the syscall can be blocked by e.g. seccomp security policy,
   therefore the need for a function to check if it's actually working,
   and a soft fallback to kill. Perhaps this precaution is not really
   needed.

3. (*Process).Wait: use pidfdWait, if available, otherwise fall back to
   using waitid/wait4. This is also more complicated than expected due
   to struct siginfo_t idiosyncrasy.

NOTE pidfdSendSignal and pidfdWait are used without a race workaround
(blockUntilWaitable and sigMu, added by CL 23967) because with pidfd,
PID recycle issue doesn't exist (IOW, pidfd, unlike PID, is guaranteed
to refer to one particular process) and thus the race doesn't exist
either.

Updates #13987.

b27d02c07b runtime/debug: clarify SetCrashOutput dup behavior
SetCrashOutput dup's the input file for safety, but I don't think that
the docs are very clear about what the caller can/should do with f. "it
does not close the previous file" is particularly confusing, as it does
close the previous FD (but not the previous passed os.File).

Expand and attempt to clarify the explanation, borrowing wording from
net.FileConn, which also dup's the input os.File.

3f60da7944 cmd/go/internal/modcmd: correctly filter out main modules in verify
This change fixes a bug where we incorrectly filtered out the main
modules from the beginning of the build list before verifying them. We
made the assumption that the first MainModules.Len() entries of the
build list were the main modules, but now it can contain the go and
toolchain version entries, so removing the first MainModules.Len()
entries could leave main module names in the build list if any of
their names sorted after the string 'go'.

Fixes #62663

3580c212c2 cmd/asm, cmd/internal/obj: enable rounding mode suffix for riscv64
This CL adds rounding modes for riscv64 floating point conversion
instructions by suffix with 5 modes: RNE, RTZ, RDN, RUP and RMM.

For example, for round to nearest (RNE), we can use `FCVTLD.RNE`
According to RISCV manual 8.7 and 9.5, we changed these
conversion instructions:

FCVTWS
FCVTLS
FCVTWUS
FCVTLUS
FCVTWD
FCVTLD
FCVTWUD
FCVTLUD

Note: Round towards zero (RTZ) by default for all these instructions above.

2908352980 cmd/compile: make jump table symbol static
The jump table symbol is accessed only from the function symbol
(in the same package), so it can be static. Also, if the function
is DUPOK and it is, somehow, compiled differently in two different
packages, the linker must choose the jump table symbol associated
to the function symbol it chose. Currently the jump table symbol
is DUPOK, so that is not guaranteed. Making it static will
guarantee that, as each copy of the function symbol refers to its
own jump table symbol.
