[GlobalISel] Fix -Wunused-variable (#193009)
These variables are only used in assertions and set outside of the
variable definition, so mark them [[maybe_unused]].
[VectorCombine] Fix transitive Uses in foldShuffleToIdentity (#188989)
The Uses in foldShuffleToIdentity is intended to detect where an operand
is used to distinguish between splats, identities and concats of the
same value. When looking through multiple unsimplified shuffles the same
Use could be both a splat and a identity though. This patch changes the
Use to a Value and an original Use, so that even if we are looking
through multiple vectors we recognise the splat vs identity vs concat of
each use correctly.
Fixes #180338

[NFC][test] Precommit test for pr188989 (#188667)
Precommit test for #188989.
This test case covers a scenario in the vector combine
foldShuffleToIdentity function where incorrect folding was caused when
different shuffle sequences shared the same initial Use *. This issue
may be due to cost model differences and currently reproduces only on
LoongArch for this test case.

[X86] Fix missing ByValTemporaries update in CopyViaTemp path for musttail calls (#190540)
This fixes a miscompilation in musttail calls with byval arguments on
X86.
In the CopyViaTemp path, a temporary stack object is created and the
argument is copied into it.
However, the temporary is not recorded in ByValTemporaries,
so the final lowering phase does not emit the copy to the real outgoing
argument slot.
As a result, the callee may read incorrect values from the stack.
Fix this by recording the temporary in ByValTemporaries so that the
final lowering step correctly copies the argument to the expected stack
location.

[libsycl] Fix _LIBSYCL_EXPORT placement (#192243)

[PatternMatchHelpers] Factor deferred and bind matchers (NFC) (#191373)

[lldb][docs] Add conference talks to the links page (#192724)
At EuroLLVM, I mentioned a previous LLDB talk and realized they would be

[LV][NFC] Rename PreferPredicateOverEpilogue to TailFoldingPolicy (#191803)
Rename the -prefer-predicate-over-epilogue flag and its associated
enum values to use 'TailFold' terminology instead of 'Predicate'. The
term 'Predicate' is overloaded in the vectorizer context and would
cause further confusion as more tail-folding styles are added.
[VPlan] CSE ScalarIVSteps recipes (#191307)
Extend getOpCodeOrIntrinsicID to return a pseudo opcode for

InductionOpcode.
[lldb] Fix crash when evaluating expressions in Wasm targets (#192893)
LLDB crashes with "LLVM ERROR: Incompatible object format!" when
evaluating expressions while debugging WebAssembly because ProcessWasm
never disables JIT. RuntimeDyld only supports ELF, MachO, and COFF
object formats, so attempting to JIT-compile an expression for a Wasm
target produces the aforementioned fatal error.
This PR avoids the crash by calling `SetCanJIT(false)` in the
`ProcessWasm` ctor. Simple expressions will still work via the IR
interpreter, while expression requiring the JIT now show a proper error
message instead of crashing.
Fixes #179915
libvmmapi: Check for allocation failure in vm_vcpu_open()
vm_vcpu_open() really should check the value returned from malloc() and
return NULL on failure. Also, all users of vm_vcpu_open() need to check
the returned value for NULL, too.

tests/socket_afinet: Fix the bind_connected_port test
The test verifies that a socket can bind to a local address assigned by
connect(2) to a different socket. It was however trying to bind to the
wrong address, and the check of the result was inverted, so this went
unnoticed. It also needs to set SO_REUSEADDR for this to succeed.

[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.

security/openvpn-devel: Update 2.7_rc6 -> post-2.7 commit 38243844
OpenVPN 2.7.0 has been released and will show up as "security/openvpn"
soon.
This port skips 2.7.0 release and continues to track development versions,
which will focus on code cleanup / refactoring for the next few months.
Use this opportunity to bring option and dependency handling more in
line with main port
- X509ALTUSERNAME is gone (always-on now in upstream source)
- ASYNC_PUSH added, with freebsd-version dependent handling of
libinotify dependency (see PR 293176)
- UNITTEST added, with libcmocka dependency if unit tests are desired
[SPIR-V] Handle [N x i8] byte addressing in SPIRVEmitIntrinsics
LLVM started generating [N x i8] types on array indexing GEPs. Emit
intrinsiscs did not know what to do with it so it was generating a
cast to [N x i8] to perform the GEP. This does not work in logical
addressing.
The handle this, we expand the `i8` gep handling for logical addressing
mode to work for arbitrary size byte addressing.
[VPlan] Remove dead partial reduction case in addReductionResultComputation. NFCI (#192985)
Partial reductions don't exist until createPartialReductions, which is
