Wait for bdev to actually disappear after delete (#19042)
spdk_bdev_unregister's cb_fn (which sends the RPC reply) fires before
spdk_bdev_close(desc) in spdk_bdev_unregister_by_name, so
bdev_aio_delete can return while the underlying close(fd) on the zvol is
still pending.

[clang][SemaCXX] Fix crash caused by unresolved overloaded function type when using `__builtin_bit_cast` (#200574)
Resolves #200112
By early checking for placeholder expressions, crash can be avoided for
unreachable builtin type when fetching type info.
[X86] Fold XOR of VGF2P8AFFINEQB and its source (#198448)
Adds a optimization to fold XORs between `vgf2p8affineqb` and its
source. That XOR can done through the existing affine transformation by
XORing its matrix with the identity matrix. This patch:
- Folds XOR between `vgf2p8affineqb` and its source.
- Only occurs when the matrix is constant, ensuring that it can't
increase the dependency chain.
- Doesn't occur if the affine is multi use, preventing an increase in
code size.
- Includes test coverage for both positive and negative cases.
Fixes #184061
[AMDGPU] Replace relaxed-buffer-oob-mode feature with module flag (#160922)
Remove AMDGPU subtarget feature toggle for relaxed buffer OOB handling
and replace it with two explicit LLVM module flags:
- amdgpu.buffer.oob.relaxed for untyped buffer instructions
- amdgpu.tbuffer.oob.relaxed for typed buffer instructions
Each flag is modeled as i32 with Max merge behavior and validated as a
tri-state value, where 0 means Any/default, 1 means Relaxed and 2 means Strict.
The absence of the module flag implies the default mode, which is currently treated
as Strict by the backend.
[flang][lowering] Implement component-wise initialization for derived types (#187465)
Currently, the compiler defaults to a full `memcpy` when initializing
derived types.
This patch introduces component-wise initialization for pointer /
allocatable components, avoiding unnecessary initialization data
generation and redundant copies.
Ineligible cases continue to use the existing `memcpy` initialization
path.
RFC: https://discourse.llvm.org/t/rfc-automatic-static-promotion-of-large-local-variables-in-flang/89539
Key changes:
- In `flang/lib/Lower/ConvertVariable.cpp`:
- Add `genDerivedTypeComponentInit` for component-wise derived type
initialization.

workflows/release-binaries: Install LLDB test deps (#199900)
lldb-api tests are hitting:

[Clang] Profile the NNS of UnresolvedUsingType and CXXThisType correctly in concept hashing (#199617)
They were sometimes incorrect because the written type doesn't contain
an NNS which contains template parameters we're interested in.
No release note because the bug broke MS STL and I want to backport it
to the last 22.x release

[DA] Fix overflow in the Exact test (#200781)
In exactTestImpl, some computations using APInt could overflow, which
might lead to incorrect results.
This patch addresses the issue by replacing APInt with
OverflowSafeSignedAPInt, a class that is sensitive to overflow and
allows us to detect it properly.
Fixes #200766.
[GlobalISel] Do not depend on the RuleMatcher at MatchTable emission
Some PredicateMatchers/MatchAction/OperandRenderers relied on accessing
RuleMatcher at emission as a crutch.
Instead, make these classes collect all necessary information in the
constructor so the `emit` methods don't depend on RuleMatcher anymore.
The primary motivation for this is that I've been looking at ways to optimize the MatchTable better,
and the fact that Predicates/Actions/Renderers are not "pure" objects, in the sense that they keep
accessing a bunch of data all over the place even as late as emission, was a consistent pain.
This is NFCI. There are no changes to any of the match table for AMDGPU/AArch64 in this patch.
This patch has a bunch of noise due to function signature changes so I'll highlight the following interesting changes:
- `SameOperandMatcher` needed a bit of an update in its `canHoistOutsideOf` function. I had to rewrite it
but I think the end result is the same.
- `EraseInstAction` has been updated as well, and its users in both Combiner/ISel backends have been updated to.
Instead of ignoring this action if the Inst was already erased, it's now the responsibility of the
builder to never insert it in the first place. `BuildMIAction` had a small update because of that too.

ntpd: use the usual error check for timegm(3).
Straightforward change. The code could use some refactoring to avoid two
consecutive timegm(3) calls on tm_tls. The layering is a bit strange here.

[InstCombine][VectorCombine] Move bitcast vp.load fold into VectorCombine (#200321)
Fixes https://github.com/llvm/llvm-project/issues/199896
In #192173 we started folding bitcasts of vp.loads with an all ones mask
into a vp.load with the casted type. However on RISC-V a vp.load of an
i1 vector is illegal (since there's no masked variant of `vlm.v`), and
we have no way of checking this in InstCombine.
This moves the fold into VectorCombine so we can query TTI if the cost
is legal (and profitable)
As a side note, it may be possible to lower a vp.load of an i1 vector on
RISC-V to `vlm.v` **only** if the mask is all ones. But this means the
lowering would only be valid for certain values, which is difficult to
cost. And I'm not sure if it would be profitable anyway.
