[SPIR-V] Always reject OpTypeVector with a non-standard width (#212685)
SPV_EXT_long_vector does not widen OpTypeVector past 4 components. Those
widths need OpTypeVectorIdEXT, so requesting the extension here was
wrong
[ADT][TableGen] Add UniquingSet, a FoldingSet with typed keys (#219630)
FoldingSet serializes a key into a FoldingSetNodeID to look a node up
and rebuilds the stored node's profile to compare against it. Where a
key can be read out of a node, neither is necessary.
UniquingSet reuses FoldingSetBase's storage, growth, removal and insert
token and replaces only the key: the node's `getKey()` supplies it, the
key type's `operator==` compares it, and DenseMapInfo hashes it inline.
An Info parameter overrides the key type or its hash. The hash cached on
each node keeps growth and erasure from calling `getKey()`, which a
DenseSet cannot avoid.
Prefer `UniquingSet` where a key can be read out of a node in O(1) and
the lookup key is built beside `getKey()`; keep FoldingSet for keys that
are wide, polymorphic or assembled at many call sites, where one Profile
helper keeps both sides consistent. insert asserts that a node hashes as
its lookup did.

[clang][docs] Suppress Sphinx highlighting failure warnings in conf.py (#220118)
Following the upgrade to Sphinx 8.2 (#219299), Pygments syntax
highlighting fallbacks (e.g. on custom C++ attribute syntaxes like
`[[clang::...]]`) emit `[misc.highlighting_failure]` warnings when
retrying in relaxed mode. Because sphinx-build runs with `-W`, these
warnings abort the documentation build.
Mirror the configuration in `llvm/docs/conf.py` by setting
`suppress_warnings = ["misc.highlighting_failure"]`.

[lld][MachO] Compare referent offsets in ICF (#219960)
ICF::equalsConstant() compared only the addends of relocations that
reference symbols in ConcatInputSections, not the symbols' offsets
within their sections. The ICF hash merely sums the referent symbols'
offsets, so two code sections whose relocations reference the same input
section at swapped offsets have equal hashes, pass both the constant and
the variable comparison, and are folded together even though they
reference different data.
Compare the symbol value plus the addend instead, as the ELF backend
does.
This issue was found by LLM while investigating why identical LSDAs were
not being folded. It has not been observed in a real-world link, and the
regression test is synthetic.

Pull forgotten EDAC updates from Borislav Petkov:
"Somewhat belated (and forgotten :-\) EDAC updates lineup for v7.3:
- Mark the mpc85xx and ThunderX EDAC drivers as orphaned due to lack
of access to hardware
- Remove the unused fake error injection interface from the EDAC
debugfs code due to potential races between logging a fake and a
real hw error
- edac_mc_sysfs: Use sysfs_emit_at() for proper bounds checking
- Remove Mark Gross from maintainer entries and move him to CREDITS
- Load the AMD address translation library only on systems which can
actually make use of it (have ECC memory) instead of on every AMD
Zen system out there

[flang][cuda] Propagate CUDA attrs from parent variable to component deallocs (#220059)
This is a follow up to
[#206614](https://github.com/llvm/llvm-project/pull/206614), which made
`allocate(foo(i)%arr(...))` inherit `foo`'s CUDA memory attribute, but
did not add the equivalent inheritance for `deallocate(foo(i)%arr)`. The
deallocation still lowered to an inlined `fir.freemem`, so memory
obtained from a CUDA allocator was released with libc `free()`.
The allocate side already walked the `DataRef` chain for a
CUDA-attributed parent, but the helpers were private to
`AllocateStmtHelper` and unreachable from the deallocate path. This
patch hoists `findCUDAAttrInDataRef` to file scope, adds
`getCUDAAttrParentSymbol(AllocateObject)` beside it, and reduces the
existing member to a thin wrapper. The allocate behavior is unchanged.
`genDeallocate` gains an optional `cudaSymbol` used only for the CUDA
decisions (`isCudaSymbol` and the `genCudaDeallocate` call).
`genDeallocateStmt` supplies the parent symbol, which is non-null only

Fixes:
- Fixed SIGINT handling.
[SelectionDAG] Fix CSE keys that disagree with SDNode::Profile (#219911)
A getNode helper builds its lookup ID by hand; matching it later
rebuilds one from the node with AddNodeIDCustom. Where the two disagree
the compare always fails and the node never CSEs. Fix whichever side is
wrong: the labels, DEACTIVATION_SYMBOL, GET/SET_FPENV_MEM and
EXPERIMENTAL_VECTOR_HISTOGRAM have no case; getLifetimeNode keys on a
frame index operand 1 already carries, getStridedLoadVP on the result
type instead of the memory type, and getPseudoProbeNode drops the
attributes its case profiles.
Ask AtomicSDNode instead of an opcode list stale since ATOMIC_LOAD_FADD,
and add the two opcodes its own classof was missing.
AddNodeIDCustom now takes the opcode to profile under, so MorphNodeTo's
pre-morph lookup keys on what the morph produces. Machine opcodes
profile nothing: the morph overlays MachineSDNode's memory references on
the fields the MemSDNode checks read.

[NFC][HLSL] Refactor texture type declaration (#219561)
Fixes https://github.com/llvm/llvm-project/issues/219542
Refactors texture type declaration in `HLSLExternalSemaSource.cpp` so
that new
texture types can more easily be added without adding a bunch of new
helper
functions.
This is accomplished with the introduction of a new `TextureTypeInfo`
struct
to record the properties of each texture type, as well as its
capabilities
indicated by the `TexCap` bitmask enum.
Adding a new texture type to be declared should, in most cases, only
require
appending a new entry to the static `TextureTypes` array of

[CSSPGO] Don't let pseudo probes block early-exit vectorization (#219872)
llvm.pseudoprobe is modeled as accessing inaccessible memory, so
mayReadFromMemory()/mayWriteToMemory() return true even though the
intrinsic
carries no real memory dependence. An otherwise vectorizable early-exit
loop
is therefore rejected as soon as it contains a pseudo probe.
This patch skips pseudo probes in isVectorizableEarlyExitLoop(),
isReadOnlyLoop() and
areAllLoadsDereferenceable() so the three checks agree and such loops
vectorize as they would without pseudo probe instrumentation.

[Clang] Honor -Xarch_gfx* when linking the UBSan offload runtime
Empty bound architecture misses per-GPU sanitizer flags, so inspect each
offload arch when deciding whether the host interceptor is required.
[Clang] Enable UBSan for AMDGPU device offload
Summary:
This enables the device UBSan runtime for AMDGPU decides. Primarily this
required modifications to the `addSanitizerRuntime` interface so we can
query the compilation's offload status. Also need to forward it through
the linker wrapper interface. Works on all AMDGPU offload, slight hacks
around the other targets as they do not advertise sanitizer
runtimes properly.
This is linked in via a new `-u __ubsan_device_initialize` hook to pull
in the side library. This is standard behavior and keeps the core logic
mostly unchanged and re-used.
