[AArch64] Skip FrameDestroy DW_CFA_AARCH64_negate_ra_state_with_pc (#198677)
The toggle semantics of DW_CFA_AARCH64_negate_ra_state_with_pc are
evaluated over a linear stream of CFI opcodes, rather than along control
flow edges, making it impossible to faithfully represent the RA state
across all CFG paths for functions with non-trivial block layouts (for
example hot-cold-splitting, or doubly-shrinkwrapped functions with
multiple independent frames).
libunwind works around this by recording the signing address at the
FrameSetup site, and not validating that the CFI state has toggled back
to "unsigned" after authentication. We can therefore omit the
FrameDestroy emission, treating the marker solely as a marker for the
signing site. This holds so long as each function has at most one
signing location, which is currently guaranteed since shrinkwrapping
does not yet create functions with more than one frame.
DW_CFA_AARCH64_set_ra_state is the correct long-term fix, but cannot be
used exclusively due to unwinder compatability concerns.

[CIR] Implement ArgKind::Expand in CallConvLowering
Struct arguments classified Expand were rejected with an errorNYI in
CallConvLowering; the System V x86-64 ABI passes small structs by
flattening them into one scalar register argument per field, so the
classifier produced Expand but the rewriter could not honor it.
Lower Expand on both sides of the call. buildNewArgTypes flattens the
struct wire type into one argument per member, and updateArgAttrs emits a
matching empty attribute dict per field. In the callee, insertArgCoercion
splits the single struct block argument into N scalar field block
arguments and stores each field straight into the parameter's own alloca
(the CIRGen spill slot), erasing the original whole-struct store so no
scratch alloca or reload is introduced; a parameter whose spill slot was
already removed by DCE is only reshaped, with no field stores. At the call
site,
rewriteCallSite decomposes the struct operand into its fields, reading each
member directly from the source alloca (get_member + load) when the operand
is a load of an alloca, and falling back to cir.extract_member on the value

clang: Replace getTargetID API with isProcessorName
The "target ID" naming is an AMDGPUism. Replace the getTargetID query
with an isProcessorName predicate so the target reports whether the
string should be considered a match. This makes alias handling more
natural than checking for exact match, and avoids an unnecessary
parse of the target ID.

[Instrumentor] Add subtype IDs to complement type IDs for vectors/arrays
If the type of an argument passed to the instrumentation is a vector or
array, we still want to filter on the underlying type, and the
instrumentation might also need to know. Thus, we can now pass a subtype
ID, which is -1 except if it's a vector or array, then it's the element
type ID. Structs need to be handled differently.

OFED: Various changes from Linux 4.19
Many of these changes deal with shifting from fetcing SGID attributes
via an index in drivers to including references to SGID attributes in
other structures passed to driver callbacks which can be used directly
avoiding the need for fetching attributes via lookup functions. I had
to fixup the ROCE GID management code directly as the version in
FreeBSD is very different from Linux.
I also tweaked the change from commit
475c8de7bf2dc86d9806709a04e9c8f524d4ec32 to use a goto to reduce diffs
with upstream to minimize conflicts when merging upstream changes.

Most of the changes involve renaming InfiBand address handles (AH) to

Address handles now also include type-specific fields and a set of
wrapper accessor functions for getting and setting fields. For some
of the type and function renames, drivers in sys/dev had to be updated
directly (typically via sed).

Optimize metaslab_set_selected_txg()
I don't think it makes much sense to choose for eviction between
metaslabs selected in the same TXG. Considering that we also don't
evict them for at least 32 TXG, the difference should be in a noise.
Just skip the metaslab bumping if we already done it in this TXG.

[docs] Create utils/docs (#203962)
llvm-project is home to many sphinx documentation sites, each with
configuration quirks and bespoke extensions.
The sphinx config model makes sharing code somewhat difficult. There
are options like sphinx-multiproject, but some of our docs builds are
out of the source tree while some are done out of the binary tree, so
the multiproject configuration itself would need to be generated. It
also would impose more uniformity around extensions than required.
This change instead creates a python package at utils/docs/llvm_sphinx
and makes it available to all sphinx-build processes via PYTHONPATH.
Each conf.py does not modify its own sys.path because not all builds are
out of the source tree, so there isn't a stable relative path to use to
refer to the utils/docs/ directory.
Type checking via pyright in new package is pinned to being python 3.8
compatible.

NAS-141545 / 27.0.0-BETA.1 / proxy nginx-middleware over a private unix socket (#19189)
This commit changes our proxy settings for nginx so that UI / API

Connections on the unix socket are classified as TCP origins from the
