[MLIR][XeGPU] Propagate layout from anchor ops before Wg To Sg & Blocking Pass (#179490)
This PR calls recoverTemporaryLayout before the XeGPUWgtoSgDistribute &
XeGPUBlocking Pass to recover all the temporary operand layout which
might be required by the transformation patterns for checks and
verification

[CIR] Implement initial flattening of cleanup scope ops (#180063)
This implements flattening of `cir.cleanup.scope` operations that have a
single exit, and introduces checks to detect multiple exit cases and
report an error when they are encountered. At this point, only normal
cleanups are flattened. EH cleanup handling will be added in a future
change.
Substantial amounts of this PR were created using agentic AI tools, but
I have carefully reviewed the code, comments, and tests and made changes
as needed.
net/mosquitto: Fix websockets options
Rename WEBSOCKET to WEBSOCKETS to match the cmake options. Add
WEBSOCKETS_BUILTIN option. I'd like to have WEBSOCKETS control if
websockets is supported at all and WEBSOCKETS_BUILTIN switch between
the bundled and ports versions but the latter doesn't build so mark
BROKEN and open an upstream issue:
https://github.com/eclipse-mosquitto/mosquitto/issues/3478
One effect of these changes is that libwebsockets is no longer a
LIB_DEPENDS for the port; this will become a possibility once
WEBSOCKETS_BUILTIN OFF works again.

[libcxx] Rename `__split_buffer` alias template to `_SplitBuffer` (#180284)
`-Wchanges-meaning` is a GCC warning that catches shadowing in more
contexts. While a bit annoying here, it's a helpful warning. As such, we
need to rename the `__split_buffer` alias template in `std::vector` so
that we don't trip it up.
expose getObjCDirectMethodCallee for swift
Swift may need to emit calls to thunks as well. Instead
of letting swift rewrite the thunk generation logic, we
might as well expose the method.
[MLIR][XeGPU] Fixing PR179016 minor issues (#180295)
Fix two issues brough by PR179016:
1. unused variable if build the option with
"DLLVM_ENABLE_ASSERTIONS=OFF"
2. Recover modification to recoverTemporaryLayouts() brought by
PR176737. Unintentionally lost during the merging process.

[clang] Canonicalizing `-include-pch` input in the Frontend (#180065)
This patch adds logic to canonicalize `-include-pch`'s input in the
frontend. This way, the `ASTWriter` always serializes the canonicalized
path to the included pch file whether the input is an absolute path or a
relative path.
Fixes rdar://168596546.
kernel - Fix serious root vulnerabilities in the caps code
* The caps code was inadvertently allowing many root-only operations
to be run from user mode, particularly mount/umount ops by assuming
a root creds check that was not taking place in some of the API
calls, but was taking place in others.
* All API calls now check root creds by default unless passed the
appropriate flag.

[LifetimeSafety] Treat std::unique_ptr::release() as a move operation (#180230)
Add support for `std::unique_ptr::release()` in lifetime analysis to
avoid false positives when ownership is manually transferred via
`release()`.
- Added a new function `isUniquePtrRelease()` to detect when
`std::unique_ptr::release()` is called
- Modified `handleInvalidatingCall()` to mark the unique_ptr as moved
when release() is called
When manually transferring ownership using `std::unique_ptr::release()`,
the lifetime analysis would previously generate false positive
use-after-free warnings. This change treats `release()` as a move
operation, correctly modeling the ownership transfer semantics and
reducing false positives in code that manually manages ownership.
kernel - Fix overflow in alist and blist code
* This code tracks swap space and large blocks of contiguous DMA memory.
* Fix overflows in array size calculations that did not take into
account terminator entries.
(a) Remove terminals from alists entirely.
(b) Account for space used by the terminator in blists.

[Clang] Mark this pointer in destructors dead_on_return (#166276)
This helps to clean up any dead stores that come up at the end of the
destructor. The motivating example was a refactoring in libc++'s
basic_string implementation in 8dae17be2991cd7f0d7fd9aa5aecd064520a14f6
that added a zeroing store into the destructor, causing a large
performance regression on an internal workload. We also saw a ~0.2%
performance increase on an internal server workload when enabling this.
I also tested this against all of the non-flaky tests in our large C++
codebase and found a minimal number of issues that all happened to be in
user code.
