[clang] remove unused NestedNameSpecifier 'Invalid' constructor
These invalid NNS were used as thombstone keys for DenseMap, but
the DenseMap implementation changed and that's not needed anymore.
[FoldingSet] Assert inserted node's profile matches its lookup (#220166)
In FoldingSetImpl::insert, assert the node profile matches the insert
token. Otherwise, a memoized node can never be matched, leading to
missing hash consing.
This would catch SelectionDAG's and clang's missing CSE bugs (#219911,
#220168)
[clang][bytecode] Allocate EvalEmitter locals using InterpState allocator (#220922)
They have the same lifetime, so might as well use the existing
allocator.
[mlir][linalg] Preserve cast semantics in named contraction vectorization (#216283)
This patch fixes correctness issues in named contraction vectorization
of Linalg ops whose operands require conversion to an integer
accumulator type.
When `create_named_contraction` is enabled, an op such as `linalg.matmul
{cast = #linalg.type_fn<cast_unsigned>}` was lowered directly to a
mixed-width `vector.contract` without materializing the implied
`arith.extui`. Since `vector.contract` promotes mixed-width integer
operands using sign extension, an `i8 x i8 -> i32` matmul could
interpret unsigned inputs as signed values and produce incorrect
results.
Floating-point operands were similarly passed directly to
`vector.contract` without materializing the `arith.fptosi` or
`arith.fptoui` conversion implied by the Linalg cast semantics.
Materialize `arith.extui` for narrower unsigned integer inputs and

extend the "mcast" pledge to allow multicast tweaks on ethernet frame sockets.
this is for lldpd, which wants to receive lldp packets sent to a
multicast address on interfaces as they attach at runtime, which
currently isn't allowed by pledge.

[IR] Add source location filtering to pass dumps (#203393)
Large dumps from `-print-after-all` can be hard to use when only a few
source lines matter. Function filtering can still print too much and can
miss code after inlining.
Add `-filter-print-source-locs` to limit IR and machine-function dumps
to matching debug locations. The option accepts file names or paths with
selected lines and ranges. It also follows inlined locations and works
with legacy and new pass managers.
tighten pledge_sockopt()s level/optname checks for different types of sockets
tl;dr: the meaning of the setsockopt and getsockopt level and optname
arguments are dependent on the type of the socket you're working
with, they can't be safely understood without knowing the address
family and protocol.
i think we've been able to ignore to socket address family and
protocol so far by luck, particularly because openbsd (henning)
removed a bunch of address families like AF_IPX and AF_NETATALK.
like AF_INET and AF_INET6, they use values from the wire protocol
as identifiers in the ABI, particularly sub protocol numbers like
IPPROTO_TCP. there's no guarantee these numbers don't overlap with
a protocol from another address family. netipx used IPXPROTO_SPX
like how AF_INET uses IPPROTO_IP, but it's only luck that their
values don't collide with each other or another protocol. this
principle applies to all socktypes though.
this is also reflected in the way sockopts are handled by protocol

[CIR][OpenCL] Emit OpenCL language version metadata in CIR
Emit OpenCL and C++ for OpenCL language version attributes from CIRGen. Preserve the compatible OpenCL version and the C++ for OpenCL version separately so later lowering does not infer one from the other.

ixl: Reset VSI statistics after initial sampling
The initial statistics update runs before the PF VSI has obtained its
firmware-assigned statistics counter index. Discard that provisional
VSI baseline so the first update after initialization records the
correct hardware counter.
Without this reset, subtracting a larger provisional value from a newly
selected counter can be mistaken for a 32-bit wrap and report nearly
UINT32_MAX receive drops immediately after boot.

[LoongArch][MC] Add assembly syntax highlighting for LoongArch (#218946)
This PR adds color highlighting of registers and immediates in LoongArch
disassembly.
This is similar to #65853.
[RISCV] Andes: model fast unaligned accesses (#220756)
Mark the Andes 45 tuning profile as supporting efficient unaligned
scalar loads and stores. This lets fixed-size alignment-one copies lower
to scalar instructions instead of a memcpy call. On these in-order
cores, where performance is almost synonymous with instruction count,
this is a material win.
