[MC] emitCodeAlignment: take MCSubtargetInfo by reference. NFC (#205140)
The fragment member cannot be null, and the sibling streamer hooks
(emitInstruction, initSections, emitPrefAlign) already take it by
reference.
[RISCV] Add a Pass for adding %qc.access specifiers (#201938)
Qualcomm's ABI has Access Relocation Markers, which are used to enable
more linker relaxations. This change implements a pass which will
annotate loads and stores (accesses) which are the single user of a
`qc.e.li`-materialized address with these markers so they can be relaxed
in the linker.
This is a follow-up to #188671.
dns/bind: add SVCB record type to BIND record model (#5508)
Adds SVCB to the Record model OptionValues so RFC 9460/9461 SVCB records
(e.g. _dns DDR records for encrypted-DNS discovery) can be created via the
plugin GUI/API. BIND 9.18+ supports SVCB natively; the plugin validation
rejected the type before it reached named. One-line change, complements the
HTTPS record type (#5425).
[Clang][Sema] Add -Wstringop-overread warning for source buffer overreads (#183004)
This PR adds a new `-Wstringop-overread` warning that diagnoses calls to
memory functions where the specified size exceeds the size of the source
buffer, increasing parity with GCC's `-Wstringop-overread`.
The warning is emitted when the read size is a compile-time constant
that is greater than the size of the source buffer (when known
statically).
This check applies to the following functions:
- `memcpy`, `memmove`, `mempcpy` (and `__builtin_` / `__builtin___*_chk`
variants)
- `memchr`
- `memcmp`, `bcmp`
Some of the existing code for `-Wfortify-source` was refactored into a
helper class to make its lambdas accessible to other functions.

[libc++] std::abs support for _BitInt(N) and __int128 (#196532)
`std::abs` does not accept `__int128` or signed `_BitInt(N)`: the call
is ambiguous and fails to compile (#204212).
This adds an explicit `abs(__int128_t)` overload and an
`abs(_BitInt(N))` overload that deduces the width, so every signed
`_BitInt` gets a same-type result. `_BitInt` does not integer-promote,
so without this overload a narrow signed `_BitInt` would be an ambiguous
call against `abs(int/long/long long)` instead of promoting the way
`signed char` and `short` do. Standard narrow types are unchanged: they
still go through `abs(int)`.
Part of the [_BitInt(N) libc++
effort](https://discourse.llvm.org/t/bitint-n-support-in-libc-investigations-possible-improvements-looking-for-guidance/90063).

[yaml2obj][MachO] Fix byte order of the indirect symbol table (#205044)
This is a follow-up of PR #203680 that added the test case
`linkedit-alignment.test`, which currently fails on big-endian buildbots
(see: https://lab.llvm.org/buildbot/#/builders/98/builds/3084 and
https://lab.llvm.org/buildbot/#/builders/114/builds/906).
The failure seems to be on `yaml2obj`, where `writeDynamicSymbolTable`
emits an indirect symbol table in host byte order rather than the
specified object's byte order (i.e. the `IsLittleEndian` field value).
This PR adds the missing swap and a regression test that round-trips all
endian-sensitive fields with both endianness values.
openimageio: updated to 3.1.14.1
3.1.14.1
Note: This patch release only fixes a build break, which is only encountered if relying on the "auto-build" of dependency OpenColorIO if you don't already have it able to be found on your system. If you aren't encountering this problem, you do not need to upgrade from 3.1.14.0.
appstream: updated to 1.1.3
Version 1.1.3
Features:
* Officially support & read JXL images for icons, validate permitted filetypes
* meson: Allow disabling command-line tools
* news-convert: Recognize "=" as release block header
* news-convert: Handle extra linebreaks better and add support for issue-blocks
* compose: Create content hashes with Blake3 instead of MD5
* Update static data for category and license additions
* validator: Tags without namespace are an error
Specification:
* docs: Convert to Docbook 5
Bugfixes:
* yaml: Ensure certain values are always explicitly emitted as strings

[lldb][bazel] Add the Windows process plugin to the bazel build (#203146)
Add a cc_library for the native Windows process plugin
(ProcessWindowsCommon),
gated to @platforms//os:windows, and register it via the dedicated
@LLDB_PROCESS_WINDOWS_PLUGIN@ slot in the generated Plugins.def. This
mirrors the
CMake build, which special-cases ProcessWindowsCommon into that slot so
it is
initialized after all other process plugins but before ProcessGDBRemote.
With the help of claude.
Tested internally at Meta by converting Bazel -> BUCK and confirming
matches working BUCK contents for windows lldb build.
Class for checking floating-point properties
Applicability of a particular transformation to floating-point
expressions may depend on many parameters. Previously these parameters
were mainly represented by fast-math flags, and in some cases they were
supplemented by rounding mode and exception behavior, and all were
passed as separate arguments to the relevant functions. Implementing
more elaborated support of floating-point requires access to other
properties, including function attributes (such as denormal mode or sNaN
support). Passing these parameters as separate arguments is
inconvenient. To address this problem a special class that collects all
the necessary information is introduced in this commit.
The class is a wrapper over an integer value, where various bit fields
represent properties, that transformations may depend on. This allows
instances of the class to be passed by value. It incorporates fast-math
flags and borrows part of the FastMathFlags interface.
This change was intended to be NFC, but in some cases, the behavior

NAS-141457 / 26.0.0-RC.1 / V-series V2xx front-bay enclosure support
Adds enclosure2.query support for V2xx (V260/V280) front-bay drives,
which are served by a single Broadcom PEX89088 PCIe switch chip
partitioned into two SES VirtualSES enclosures (replacing V1xx's dual
9600w-12i4e SAS HBAs).
Key V2xx differences handled here:
- The two PEX89088 SES partitions advertise the SAME encid (SAS
address), so the V1xx encid-comparison disambiguation fails.
ses_enclosures2 now falls back to inspecting Array Device Slot element
descriptor labels ('slot01'..'slot12' identifies the NVME0 partition;
'slot13'..'slot24' identifies NVME8).
- V2xx slot indexing differs from V1xx: each partition exposes its 12
owned slots at libsg3 element keys 1-12 (NVME0) or 13-24 (NVME8),
with sysfs slot files matching the key 1:1. slot_mappings now branches
by enc.product so the V2xx table is picked for ECStream 4IXGA-SWp/s.

NAS-141457 / 26.0.0-RC.1 / V-series rear-bay enclosure support via bifurcated NTG SES partition
Adds enclosure2.query support for V-series rear bays (V140, V160, V260,
V280) served by the bay-serving half of the bifurcated PEX89032 NTG
chip. The other half has no drives and is dropped from enclosure2.query
— discriminated by Array Device Slot descriptor labels ('slot01'..'slot04'
identifies the bay-serving partition; '<empty>' identifies the no-drives
half). Both halves share the same vendor / product / encid, so descriptor
labels are the only discriminator.
Changes:
- ses_enclosures2 adds _VSERIES_REAR_PRODUCTS, the
_vseries_rear_partition_owns_bays discriminator, and
_initialize_v_series_rear_enclosures (picks the bay-serving partition,
tags it slot_designation='REAR', drops the no-drives partition).
get_ses_enclosures grows a deferred_rear bucket and dispatches via the
unified _initialize_v_series_enclosures wrapper.
