math/rand/v2: add ChaCha8
ChaCha8 provides a cryptographically strong generator
alongside PCG, so that people who want stronger randomness
have access to that. On systems with 128-bit vector math
assembly (amd64 and arm64), ChaCha8 runs at about the same
speed as PCG (25% slower on amd64, 2% faster on arm64).
Obviously all the claimed benchmark variation other than the
new ChaCha8 benchmark is a lie.

go/types, types2: implement Alias proposal (export API)
This CL exports the previously unexported Alias type and corresponding functions and methods per issue #63223. Whether Alias types are used or not is controlled by the gotypesalias setting with the GODEBUG environment variable. Setting gotypesalias to "1" enables the Alias types: GODEBUG=gotypesalias=1 By default, gotypesalias is not set. Adjust test cases that enable/disable the use of Alias types to use -gotypesalias=1 or -gotypesalias=0 rather than -alias and -alias=false for consistency and to avoid confusion. For #63223.

debug/elf,cmd/link: add additional relocations for loong64
The Linker Relaxation feature on Loong64 is already supported in binutils 2.41. The intermediate code generated after enabling this feature introduces three reloc types R_LARCH_B26, R_LARCH_ADD32 and R_LARCH_SUB32. The other relocation types are not currently used when running all.bash, but in order to avoid the host tool chain making the decision to use it we don't have to catch it every time.

math/rand/v2: delete Mitchell/Reeds source
These slowdowns are because we are now using PCG instead of the
Mitchell/Reeds LFSR for the benchmarks. PCG is in fact a bit slower
(but generates statically far better random numbers).

On the other hand, compared to the original "update benchmarks" CL,
the cleanups we've made more than compensate for PCG being a bit
slower than LFSR, at least on 64-bit x86. ARM64 (Apple M1) is a bit
slower: perhaps the 64x64→128 multiply is slower there for some reason.
386 is noticeably slower, but it's also a non-SSA backend.

math/rand/v2: add PCG-DXSM
For the original math/rand, we ported Plan 9's random number
generator, which was a refinement by Ken Thompson of an algorithm
by Don Mitchell and Jim Reeds, which Mitchell in turn recalls as
having been derived from an algorithm by Marsaglia. At its core,
it is an additive lagged Fibonacci generator (ALFG).
Whatever the details of the history, this generator is nowhere
near the current state of the art for simple, pseudo-random
generators.
This CL adds an implementation of Melissa O'Neill's PCG, specifically
the variant PCG-DXSM, which she defined after writing the PCG paper
and which is now the default in Numpy. The update is slightly slower
(a few multiplies and adds, instead of a few adds), but the state
is dramatically smaller (2 words instead of 607). The statistical
output properties are better too.
A followup CL will delete the old generator.
PCG is the only change here, so no benchmarks should be affected.
Including them anyway as further evidence for caution.

math/rand/v2: add, optimize N, UintN, Uint32N, Uint64N
Now that we can break the value stream, we can take advantage
of better algorithms that have been suggested since the original
code was written.
Also optimizes IntN, Int32N, Int64N, Perm (indirectly).
All the N variants (IntN, Int32N, Int64N, UintN, N, etc) now
return the same values given a Source and parameter n, so that
for example uint(r.IntN(10)) and r.UintN(10) and r.N(uint(10))
are completely interchangeable.
Int64N4e18 gets slower but that is a near worst case for
the algorithm and is extremely unlikely in practice.
32-bit Int32N variants got slower too, by 15-30%, in exchange
for speeding up everything on 64-bit systems and consistency
across the N functions.
Also rename previously missed benchmark
GlobalInt63Parallel to GlobalInt64Parallel.

math/rand/v2: change Source to use uint64
This should make Uint64-using functions faster and leave
other things alone. It is a mystery why so much got faster.
A good cautionary tale not to read too much into minor
jitter in the benchmarks.

math/rand/v2: rename various functions
Int31 -> Int32 Int31n -> Int32N Int63 -> Int64 Int63n -> Int64N Intn -> IntN The 31 and 63 are pedantic and confusing: the functions should be named for the type they return, same as all the others.

html/template: support parsing complex JS template literals
This change undoes the restrictions added in CL 482079, which added a blanket ban on using actions within JS template literal strings, and adds logic to support actions while properly applies contextual escaping based on the correct context within the literal. Since template literals can contain both normal strings, and nested JS contexts, logic is required to properly track those context switches during parsing. ErrJsTmplLit is deprecated, and the GODEBUG flag jstmpllitinterp no longer does anything.

syscall: add support to get pidfd from ForkExec on Linux
Add PidFD support, so that if the PidFD pointer in SysProcAttr is not nil, ForkExec (and thus all its users) obtains a pidfd from the kernel during clone(), and writes the result (or -1, if the functionality is not supported by the kernel) into *PidFD. The functionality to get pidfd is implemented for both clone3 and clone. For the latter, an extra argument to rawVforkSyscall is needed, thus the change in asm files. Add a trivial test case checking the obtained pidfd can be used to send a signal to a process, using pidfd_send_signal. To test clone3 code path, add a flag available to tests only. Updates #51246.

crypto/tls: add WrapSession and UnwrapSession
There was a bug in TestResumption: the first ExpiredSessionTicket was inserting a ticket far in the future, so the second ExpiredSessionTicket wasn't actually supposed to fail. However, there was a bug in checkForResumption->sendSessionTicket, too: if a session was not resumed because it was too old, its createdAt was still persisted in the next ticket. The two bugs used to cancel each other out.

crypto/tls: add SessionState and use it on the server side
This change by itself is useless, because the application has no way to access or provide SessionStates to crypto/tls, but they will be provided in following CLs.

crypto/tls: support QUIC as a transport
Add a QUICConn type for use by QUIC implementations. A QUICConn provides unencrypted handshake bytes and connection secrets to the QUIC layer, and receives handshake bytes.

slices: add sorting and comparison functions
Now that the `cmp` package exists, sorting and comparison functions from `x/exp/slices` can be ported to the standard library, using the `cmp.Ordered` type and the `cmp.Less` and `cmp.Compare` functions. This move also includes adjustments to the discussions in #60091 w.r.t. NaN handling and cmp vs. less functions, and adds Min/Max functions. The final API is taken from https://github.com/golang/go/issues/60091#issuecomment-1553850782 Updates #60091 Change-Id: Id7e6c88035b60d4ddd0c48dd82add8e8bc4e22d3 Reviewed-on: https://go-review.googlesource.com/c/go/+/496078 Reviewed-by: Ian Lance Taylor <iant@google.com> Reviewed-by: Eli Bendersky <eliben@google.com> Run-TryBot: Eli Bendersky <eliben@golang.org> TryBot-Result: Gopher Robot <gobot@golang.org> |

debug/elf: define R_PPC64_REL24_P9NOTOC
This relocation is not (yet?) defined in ELFv2, but has been added to gnu gas a couple years ago. It is the same reloc as R_PPC64_REL24_NOTOC, but hints power10 instructions should not be emitted.
