AMDGPU: Remove some assembler tests using dummy target (#212595)
In the future it will be illegal to do anything with a binary
without a specific subarch. Most of these were redundant with an
existing run line.

[mlir][MathToXeVM] Convert fastmath math ops on size-1 vectors (#211921)
SPIR-V has no size-1 vector type, so `convert-math-to-xevm` previously
rejected `math.exp fastmath<fast> : vector<1xf32>` (and the other native
OCL patterns), leaving them as unconverted `math.exp`. These degenerate
size-1 vectors are the result of the XeGPU pipeline distributing and
linearizing larger vectors down to a single element per lane, so in
practice fastmath exps in e.g. flash-attention softmax were never
lowered to `__spirv_ocl_native_exp`, hurting performance.
Handle size-1 vectors by unwrapping them to the scalar element type:
`vector.extract [0]` -> scalar native intrinsic -> `vector.broadcast`
back. `vector::ExtractOp`/`BroadcastOp` are marked legal in the
conversion target so the partial conversion does not roll back, and the
pass now depends on the Vector dialect.

NAS-141967 / 26.0.0-RC.1 / Fix termination of clustered secrets key names (by anodos325) (#19433)
This commit fixes an issue where the clustered secrets file entries were
being migrated with a terminated an extra null for their name. The
termination behavior depends on the particular tdb file in question in
samba / winbind.

AMDGPU: Eliminate old macro driven processor name parsing
Previously the generated inc file had a series of macros for use
with StringSwitch; now just directly scan the generated name table.

tcp: improve handling of stopped timers
When a TCP timer is stopped, t_timers[] is set to SBT_MAX. Adding the
corresponding t_precisions[], if it is not zero, would result in
overflows in tcp_timer_next(). To avoid this, skip stopped timers.
The problem was identified while debugging uperf by Lukas Book and
an initial patch was provided by him. The committed patch was
suggested by glebius.
The problem can be observed by running netstat -nxptcp and looking for
negative timer values and by observing very long running timers in
some cases.

AMDGPU: TableGen subarch to major subarch table
Replace the hand-written AMDGPUMajorFamilies array with a
generated lookup table. Adds a special case for the major
arches missing a concrete generic target definition (we probably
should just define those to avoid this).

[RISCV] Add macro fusion support for the Xqci extension instructions (#209542)
Add macro fusion definitions for the Qualcomm Xqci extension covering
movimm-alu, movimm-mul, movimm-ldst, movimm-jump, movimm-longlogical,
movimm-mov, mov-mov, mov-longlogical fusions.
The fusion definitions live in a new RISCVMacroFusionXQCI.td which is
included from RISCVMacroFusion.td. A MIR test and the feature list test
are updated accordingly.
To accomodate additional features, increased MAX_SUBTARGET_FEATURES to
448 (from 384).

[libc] Implement cpp::unique_ptr utility (#206701)
[libc] Implement cpp::unique_ptr utility
Implemented cpp::unique_ptr and cpp::default_delete in
libc/src/__support/CPP/unique_ptr.h for internal use within LLVM-libc.
* Added cpp::default_delete and its array specialization.
* Implemented cpp::unique_ptr with support for custom deleters and
array specialization.
* Applied LIBC_TRIVIAL_ABI to unique_ptr and LIBC_NO_UNIQUE_ADDRESS to
the
deleter to enable empty member optimization and register-passing ABI.
* Defined portable LIBC_NO_UNIQUE_ADDRESS and LIBC_TRIVIAL_ABI macros in
attributes.h.
* Included is_assignable.h in type_traits.h to support conversion
assignment constraints.
* Modernized template constraints using enable_if_t and
is_convertible_v.

[libc++] Require selecting a machine when dispatching the benchmark workflow (#212591)
This resolves a TODO to allow selecting which machine we're running on.
As I am working on automation to dispatch these benchmarking jobs, it
turns out that we always want to specify the machine, and we always want
to specify a single machine to run per workflow, since this is the only
way we can track which commits have been attempted (or are still in
flight) on a given machine.
Therefore, the ability to run benchmarks on all machines at once is
removed from this workflow (but not from the related PR A/B benchmarking
workflow).
This patch also includes the machine name and the commit being
benchmarked into the runs's name, which is necessary for automation to
know what the workflow was benchmarking.
[RISC-V] Do not emit cm.popret[z] with zicfiss (#196267)
When emitting shadow call stack protection instructions, the push/pop
optimization needs to be turned off because an sspopchk before a
cm.popret[z] is guaranteed to fail in a non-leaf function. In addition,
the sspopchk must be emitted after a cm.pop so that the ra has the
correct value when the check is performed.

kern_pdwait(): print the process pointer through pd
to avoid using uninitialized value in the KASSERT() statement on the first
iteration.
Also, do the assert under the proctree_lock, which is not critical but
satisfies the invariants.
