[AsmParser] Apply deferred debug locations before intrinsic upgrade. (#200779)
Intrinsic upgrades may delete instructions, leaving dangling pointers
that may be accessed when applying deferred debug locations after
91b77dc (#200649).
Fix by applying deferred debug locations before intrinsic upgrade.

[mlir][bufferization] Implement e2e IR transformation for static memory planner
This adds the complete transformation pass that converts multiple
memref.alloc/dealloc pairs into a single arena with subviews.
The offset assignment is intentionally simple (just sequential) - this
establishes the e2e pipeline so we can add smarter bin-packing later.
Tests verify arena sizing, sequential offsets, and that dynamic shapes
or missing deallocations are correctly skipped.
[DA] Add test for the Exact test misses dependency due to overflow (NFC) (#200780)
This patch adds a test case that demonstrates that the Exact test misses
the dependency due to mishandling of overflow. The test case is taken
from #200766.
[AArch64] Lower scalable i64 CLMUL with SVE2/SME (#198999)
When AES or SSVE-AES are not available, but SVE2 or SME are,
clmul.nxv2i64 can benefit from a cross-byte CLMUL of .S precision. This
re-uses the functionality added for nxv8i16.
[Support] Take ArrayRef in convertWideToUTF8 (#200687)
`convertWideToUTF8` took a `std::wstring`, but it never modified its
data. An `ArrayRef` or `std::wstring_view` are sufficient here. I chose
`ArrayRef<wchar_t>` over `std::wstring_view`, because it can be
implicitly constructed from any range that provides `data()` and
`size()`. A second overload taking a `const wchar_t *` is provided to
convert null terminated wide C-strings.
[Liveness][analyzer] Fix handling of [[assume]] attributes (#198618)
Before this commit, if the analyzer encountered code like
```
int f(int a, int b) {
[[assume(a == 2), assume(b == 3)]];
return a + b;
}
```
it performed the following steps:
1. It visited the expression `a == 2` with `ExprEngine::Visit` (after
visiting its sub-expressions, within the regular visitation that visits
each statement of the `CFGBlock`). This triggered the `EagerlyAssume`
logic and separated two execution paths.
2. It discarded the result bound to `a == 2` from the `Environment`
because `a == 2` is not a direct child of the `AttributedStmt`.
3. Analogously, it visited an evaluated `b == 3`.
4. Analogously, it discarded the result bound to `b == 3`.
5. On each execution path `VisitAttributedStmt` was reached, it ran the

libheif: update to 1.23.0.
This is a smaller release that adds API functions to read and write metadata:
ambient viewing environment
nominal diffuse white luminance
It also adds a output_image_nclx_profile_passthrough option to
heif_decoding_options to pass through the input image NCLX without
doing any internal color conversion.

[libsycl] Add single_task (#192499)
Depends on liboffload PR:
https://github.com/llvm/llvm-project/pull/194333.
The approach with void sycl_kernel_launch(pack of arguments) implies
that
we can use or copy arguments only during that call. Since it pass only
kernel arguments as parameters and returns void - we have to split
setting
of extra kernel data like event dependencies and range and getting
result
event from arguments handling and direct kernel submision if it is
possible. Key stages: 1) passing to queue (or handler in future)
dependency
events and range (for parallel_for), saving them in queue (copy/move).
2)
wrapping kernel arguments into typeless wrappers (pointer based,

[LifetimeSafety] Add support for lifetime capture_by (#196884)
This PR implements support for the `[[clang::lifetime_capture_by(X)]]`
attribute within the lifetime-safety analysis.
The PR introduces a new helper in `FactGenerator.cpp` called
`handleLifetimeCaptureBy` which detects
`[[clang::lifetime_capture_by(X)]]` on parameters. If detected, the
analyzer now generates an `OriginFlowFact` ensuring that captured
dependencies are added to the capturer's state. The PR supports
capture_by params and `this` and currently doesn't implement attributes
on function declarations.
Example:
Integrate `[[clang::lifetimebound]]`: This existing Clang annotation is
crucial for specifying that the lifetime of a function's output is tied
to one of its inputs.
