[SPIR-V] Preserve offset alignment in pointer cast legalization (#209251)
Splitting a load/store into per-element accesses reused the original
alignment for every element, which could wrongly strengthen or discard
alignment
Compute each split access alignment via commonAlignment with its
DataLayout derived byte offset matching SPIRVLegalizerInfo.cpp
[SPIR-V] Remove dead typed pointer check in getArgSPIRVType (#209515)
Arg->getType() can never be a TypedPointerType since opaque pointers are
now the only pointer representation in LLVM IR
[CycleInfo] Remove GenericCycle::TopLevelCycle. NFC (#209677)
moveTopLevelCycleToNewParent maintains TopLevelCycle eagerly, rewriting
the whole re-parented subtree with depth_first. When discovery nests k
cycles one by one this is quadratic, and the df_iterator walk plus its
visited set dominate construction on deep nests (~78% of time on a
1500-deep nest).
Walk ParentCycle links in getTopLevelParentCycle instead and delete the
member. The walk is valid during construction too: parent links are
always current, and discovery queries blocks whose innermost cycle sits
at the top of the forest being merged, so the walk is short.

[libc] Remove #include <sys/whatever.h> (#209449)
and replace with granular includes of type/macro proxy headers -- where
those headers exist. I'm leaving the creation of new proxy headers for
another patch.

AMDGPU: Migrate CodeGen tests to amdgpu subarch triple (38)
Mechanically migrate the command-line target spelling on llc/opt RUN lines in
llvm/test/CodeGen/AMDGPU from -mtriple=amdgcn ... -mcpu=<gfx> to the folded
subarch triple form (e.g. -mtriple=amdgpu9.00-amd-amdhsa), dropping the
redundant -mcpu.

clang-linker-wrapper: Use AMDGPU::TargetID for image compatibilty (2) (#209563)
This reverts commit aa5960600ac38fcd923e69777bad1293f56658d7.
Before the first attempt, clang-linker-wrapper inconsistently
applied linker reasoning to the target ID feature modifiers, but
not the base processor. e.g., gfx90a was considered mergable
with gfx90a:xnack+.
The first attempt at this changed introduced and used
TargetID::isCompatibleWith, which applied full linking
compatibility logic. This broke tests which combined
generic and covered non-generic targets in the build (e.g.,
gfx9-generic and gfx900). The archives would both be treated
as compatible, resulting in multiple definition errors.
Split the TargetID compatibility checks into 2 different kinds:
1 for exact target match used for archives, and 1 for logical
compatibility usable for objects. For archive purposes, this stops

[RISCV][MC] Improve GPR Error Messages (#209669)

[Docs] Document Qualification WG artifacts and meeting archive (#209382)
# Summary
Update the LLVM Qualification Working Group page to point readers to the
group's directory in the `llvm-wgs` repository.
The new **Working Group artifacts** section explains that the directory
is the central location for the group's public technical outputs and
working materials, including qualification guidance, templates,
analyses, and proposals.
The **Meeting Materials** section is also updated to reflect the
migration of meeting materials, agendas, and minutes to the `llvm-wgs`
repository. The repository is presented as the long-term archive, while
the existing Discourse thread remains the location where upcoming
agendas and newly published minutes are shared.

[libc] Implement inet_ntoa (#208702)
Implement inet_ntoa, reusing the internal net::ipv4_to_str helper that
backs inet_ntop.
The result is stored in a *thread-local* static buffer. A thread-local
buffer is not required for POSIX conformance, but there is some
precedent for that, both in llvm libc (e.g. `strsignal`) and in glibc
(whose `inet_ntoa` uses it). I'm doing the same for maximum
compatiblity.

[mlir][linalg] Refine pack/unpack simplification checks (NFC) (#209522)
Update `isPackOn1D`, which is used by both
`SimplifyPackToExpandShape` and `SimplifyUnPackToCollapseShape`:
* Rename it to `isPackOnEffectively1D` to better reflect its
functionality: the underlying pack can be multi-dimensional.
* Add checks to ensure that the unique non-unit inner tile is used to
tile the unique non-unit unpacked dimension (that was previously
left as an unchecked assumption).
* Add comments to the test file for these patterns, grouping the tests
according to the functionality/cases being tested.
[libc][bazel] Add recently added sys/socket functions and syscall wrappers (#209457)
This patch adds the missing functions to BUILD.bazel:
- recvmmsg
- sendmmsg
- setsockopt
- shutdown
I also add the corresponding syscall wrapper libraries that these
functions depend on, along with a couple of additional type libraries.
I'm leaving the remaining sys/socket functions and test suites out for
now since some of them require additional infrastructure or type
definitions.

[libc][realpath][test] Create test files/directories
Follow-up PRs will add path validation etc to `realpath`, which will require paths to exist in the filesystem.
[libc][realpath] Validate path components.
This PR updates `realpath` to validate paths and return `ENOTDIR` or `ENOENT` according to https://pubs.opengroup.org/onlinepubs/9699919799/functions/realpath.html.
This PR also bumps the memory limit in `HermeticTestUtils.cpp`. The realpath unit tests allocate quite a few strings. Since memory in hermetic tests is never free'd, the unit test quickly reaches the limit.
