[LegalizeTypes][RISCV] Don't widen expandload or compresstore with VP_LOAD/VP_STORE. (#193294)
We don't support expanding/compressing VP_LOAD/VP_STORE yet.
This probably crashes on scalable vectors, but that's better than
a silent miscompile.
Fixes #193277.
[libc] Improve lit test discovery and execution (#192993)
Updated LibcTest to support cross-compilation and custom test
directories:
* Passed localConfig to _isTestExecutable to check for emulator.
* Skipped host execution permission check if emulator is set.
* Supported tests in libc.test.shared and libc.test.utils.
* Handled fallback if @BINARY@ is missing in test command template.
* Removed UnitTest from excludes in lit site config.
[cross-project-tests] Add llvm-modextract as a dependency (#193296)
cross-project-tests/dtlto/multimodule.test uses it
Some precommit tests are failing because of this missing dependency,
e.g. https://github.com/llvm/llvm-project/actions/runs/24729694507
[Github] Bump Github Runner Version to 2.334.0 (#193318)
Release notes imply this probably shouldn't impact us. Update the runner
version in the containers so that we do not run past the support
horizon.
[lldb] Add synthetic variable support to Get*VariableList. (#181501)
This patch adds a new flag to the lldb_private::StackFrame API to get variable lists: `include_synthetic_vars`. This allows ScriptedFrame (and other future synthetic frames) to construct 'fake' variables and return them in the VariableList, so that commands like `fr v` and `SBFrame::GetVariables` can show them to the user as requested.
This patch includes all changes necessary to call the API the new way - I tried to use my best judgement on when to include synthetic variables or not and leave comments explaining the decision.
As a consequence of producing synthetic variables, this patch means that ScriptedFrame can produce Variable objects with ValueType that contains a ValueTypeExtendedMask in a high bit. This necessarily complicates some of the switch/case handling in places where we would expect to find such variables, and this patch makes best effort to address all such cases as well. From experience, they tend to show up whenever we're dealing with checking if a Variable is in a specified scope, which means we basically have to check the high bit against some user input saying "yes/no synthetic variables".
[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
Fixes #8740
Fixes #61818
Fixes #190388
[LifetimeSafety] Add support for `new`/`delete` (#192504)
This PR extends LifetimeSafety to also support heap allocations via
`new`/`delete`.
# Contents
* Adds a new warning that is emitted on use-after-free.
* Renames `reportUseAfterFree` to `reportUseAfterScope` due to the old
name being misleading (warnings are still called `use_after_scope`).
* Adds a new `AccessPath::Kind` value `NewAllocation` that is used for
loans issued from `new` allocations.
* Adds `VisitCXXNewExpr` and `VisitCXXDeleteExpr`, which handle loan
issuance / origin propagation for `new` / `delete`.

[Clang][AMDGPU] Use unsigned for D# (#193310)
The descriptor should be unsigned in the first place. Before we moved to
`_ExtVector`, everything just relied on implicit type conversion, so
this was never caught. CLR's implementation of D# uses unsigned as well.
Fixes ROCM-23449.
[flang][acc] Update fir.convert rematerialization handling (#193301)
As of https://github.com/llvm/llvm-project/pull/184218 fir.convert was
being treated as a rematerialization candidate always. However, the
primary problem intended to be solved were improper classification of
pointers due to being casted to integers. Thus use optionally
implemented interface instead to only handle this scenario.
[AArch64] Add more scalar testing for hadd patterns. NFC (#193313)
These are mostly taken from hadd-combine.ll, testing scalar instead of
vector
and checking a few extra variants.
[RISCV][GlobalISel] Lower G_MEMCPY_INLINE (#192671)
Before this, MIR that contained G_MEMCPY_INLINE has failed in the
lagalization stage.
This patch calls `lower` on G_MEMCPY_INLINE.
[Attributor] Use trivial no side effects check in isAssumedSideEffectFree (#193303)
This PR should not change any tests, which is the goal here. To use
`mayHaveSideEffects` is a shortcut to avoid expensive checks by pulling
in different kind of dependences.
That said, this PR doesn't really need a test.
Reapply "[JTS][Passes] Enable JTS By Default" (#193300)
Reverts llvm/llvm-project#192894
Remaining issues should be fixed by

[libc] Add wcsxfrm (#191692)
This patch adds wcsxfrm to LLVM libc.
It includes:
- wchar.yaml declaration
- implementation and header
- CMake wiring
- entrypoint registration
- unit tests
The current implementation provides C/POSIX-style behavior and does not
yet add locale-aware collation support.
Tested with:
- ninja libc.test.src.wchar.wcsxfrm_test
Notes:
- local full check-libc was blocked by unrelated pre-existing timeout

ix(4): Add support for firmware logging for E610 adapters
This is part 3 of the support for the new Intel Ethernet E610
family of devices
The ix driver now enables firmware logging on Intel E610 devices
for debugging with Customer Support. Logs are enabled by default
and generated in binary format that requires decoding by support
teams. The collected data is firmware and hardware related for
debugging purposes only.
When the driver loads, it creates a fw_log sysctl node under the
debug section. Events are organized into categories (modules) for
targeted logging, and users can adjust verbosity levels as needed.
This adds sysctl support for the firmware logging feature and
updates the ix(4) manual page with documentation.
