[libc++][NFC] Move __memory/aligned_alloc.h into src/ (#166172)
This header is only ever used inside `src/`, so we might as well move it
there. As a drive-by this also removes some dead code.
Fix NVMe-oF failover test reliability and add diagnostics
- Fix flush method: send_flush() -> flush_namespace()
- Add read retry loop for namespaces not ready after failover
- Increase teardown sleep from 5s to 15s for cleanup
- Add fixture lifecycle logging to diagnose teardown issues
- Verify service state and port release after stop
NAS-138680 / 26.04 / Fix NFS share alert test (#17703)
The temporary dataset and share were re-using names of existing datasets
and shares causing the test to fail.
This also occurs in Goldeye.
The test fails only when run with the other tests in the test_300_nfs.py
module.
This PR makes the names unique and allows the test to pass.

[lldb] Add mock dwarf delegate for testing dwarf expressions (#168468)
This commit adds a `MockDwarfDelegate` class that can be used to control
what dwarf version is used when evaluating an expression. We also add a
simple test that shows how dwarf version can change the result of the
expression.
[libcxx] [test] Fix the gets-removed.verify.cpp test with Clang 21 (#169235)
This fixes test errors like this, at least for a mingw target, if
building with Clang 21 instead of Clang 20, as in the CI environment:
# .---command stderr------------
# | error: 'expected-error' diagnostics seen but not expected:
# | File C:\a\llvm-mingw\llvm-mingw\llvm-project\libcxx\test\std\input.output\file.streams\c.files\gets-removed.verify.cpp Line 16: cannot initialize a parameter of type 'char *' with an lvalue of type 'const char *'
# | 1 error generated.
# `-----------------------------
# error: command failed with exit status: 1
This extra, unexpected diagnostic appears in Clang 21, since commit
9eef4d1c5fa6b1bcbbe675c14ca8301d5d346f7b ("Remove delayed typo
expressions"). Before this, we got the expected diagnostic `error: no
member named 'gets' in namespace 'std'`, with the typo correction hint
`did you mean 'puts'?`. After this change, we get the typo correction
hint `did you mean simply 'gets'?` instead. And with the typo correction
finding `::gets`, it goes on to produce a second diagnostic about

[OpenMP][flang] Lowering of OpenMP custom reductions to MLIR (#168417)
This patch add support for lowering of custom reductions to MLIR. It
also enhances the capability of the pass to automatically mark functions
as "declare target" by traversing custom reduction initializers and
combiners.
CodeGen: Add LibcallLoweringInfo analysis pass
The libcall lowering decisions should be program dependent,
depending on the current module's RuntimeLibcallInfo. We need
another related analysis derived from that plus the current
function's subtarget to provide concrete lowering decisions.
This takes on a somewhat unusual form. It's a Module analysis,
with a lookup keyed on the subtarget. This is a separate module
analysis from RuntimeLibraryAnalysis to avoid that depending on
codegen. It's not a function pass to avoid depending on any
particular function, to avoid repeated subtarget map lookups in
most of the use passes, and to avoid any recomputation in the
common case of one subtarget (and keeps it reusable across
repeated compilations).
This also switches ExpandFp and PreISelIntrinsicLowering as
a sample function and module pass. Note this is not yet wired
up to SelectionDAG, which is still using the LibcallLoweringInfo
constructed inside of TargetLowering.
AMDGPU: Fix a comment (#169403)
This verifier check will complain if there aren't enough implicit
operands -- so it doesn't *allow* those operands, it *requires* them.
[ADT] Fix implicit reliance on cassert in StringTable.h (#169324)
Adds an explicit include of `<cassert>` in StringTable.h rather than
relying on the one in StringRef.h. Fixes potential compile errors if
assert() was undef'ed between StringRef.h and StringTable.h inclusion.

setcred(): Remove an optimization for when cr_groups[0] was the egid
Because setcred() has (always) treated the effective GID separately from
the supplementary groups, when cr_groups[0] was storing the effective
GID, it internally needed to build an array containing both the
effective GID and the specified supplementary groups to eventually call
crsetgroups_internal().
As kern_setcred() was only used to actually implement
user_setcred()/sys_setcred(), which need to allocate a buffer to copy in
the userland groups array into, some optimization was put in place where
these would allocate an array with one more element than
'wc_supp_groups', copyin() the latter into the subarray starting at
index 1 and pass the pointer to the whole array to kern_setcred() in
'preallocated_groups'. This would allow kern_setcred() not to have to
allocate memory again to make room for the additional effective GID.
Since commit be1f7435ef21 ("kern: start tracking cr_gid outside of
cr_groups[]"), crsetgroups_internal() only takes supplementary groups,

mdo(1): Avoid calling getgroups() in some unnecessary cases
If the basis for supplementary groups are the current ones, we do not
need to fetch them when they are to be replaced entirely (which we
already have been doing), as in the '!start_from_current_groups' case,
but specifically also when they are not going to be touched at all.
This change in passing makes the modified code block's comment saying
that SETCREDF_SUPP_GROUPS need not be set here correct.

[Flang][OpenMP][MLIR] Initial declare target to for variables implementation (#119589)
While the infrastructure for declare target to/enter and link for
variables exists in the MLIR dialect and at the Flang level, the current
lowering from MLIR -> LLVM IR isn't in place, it's only in place for
variables that have the link clause applied.
This PR aims to extend that lowering to an initial implementation that
incorporates declare target to as well, which primarily requires changes
in the OpenMPToLLVMIRTranslation phase. However, a minor addition to the
OpenMP dialect was required to extend the declare target enumerator to
include a default None field as well.
This also requires a minor change to the Flang lowering's
MapInfoFinlization.cpp pass to alter the map type for descriptors to
deal with cases where a variable is marked declare to. Currently, when a
descriptor variable is mapped declare target to the descriptor component
can become attatched, and cannot be updated, this results in issues when
an unusual allocation range is specified (effectively an off-by X

[MLIR][OpenMP] Introduce overlapped record type map support (#119588)
This PR introduces a new additional type of map lowering for record
types that Clang currently supports, in which a user can map a top-level
record type and then individual members with different mapping,
effectively creating a sort of "overlapping" mapping that we attempt to
cut around.
This is currently most predominantly used in Fortran, when mapping
descriptors and there data, we map the descriptor and its data with
separate map modifiers and "cut around" the pointer data, so that wedo
not overwrite it unless the runtime deems it a neccesary action based on
its reference counting mechanism. However, it is a mechanism that will
come in handy/trigger when a user explitily maps a record type (derived
type or structure) and then explicitly maps a member with a different
map type.
These additions were predominantly in the OpenMPToLLVMIRTranslation.cpp
file and phase, however, one Flang test that checks end-to-end IR
