[SPIR-V] Simplify addrspacecast for null in composite constant preprocessing (#192030)
Fold addrspacecast(null) to a typed null pointer during composite
constant preprocessing so that null pointer members in structs and
arrays get the correct SPIR-V pointer type instead of being lowered as
integers. This fixes invalid SPIR-V where OpConstantNull had an integer
type instead of a pointer type, and where OpSpecConstantOp was
unnecessarily emitted for null casts

[llvm-readobj][ELF] Remove redundant error in reportWarning
If MapOrError contains no error, calling takeError() results in
undefined behavior and may crash the program.

[AArch64] Factor out handling of AUTRELLOADPAC addend in AsmPrinter (NFC) (#192076)
In `AArch64AsmPrinter`, move the emission of code that handles the
Addend operand of AUTRELLOADPAC from `emitPtrauthAuthResign` to a
separate function.
Make use of recently added helper functions and update the comments.
Refer to named `Pointer` and `Scratch` registers instead of
hardcoding X16 and X17.
[Object][ELF] Pass Error to WarningHandler
Warning consumers may need to handle errors based on their type. Pass
the Error object instead of a string representation to enable this. This
also brings WarningHandler in line with Support/WithColor.h.
[Support] Add WrappedError class
The error consumer filters duplicate errors based on a portion of the
error message. Introduce a new Error kind that carries a prefix string
to support this use case.

[llvm-readobj][ELF] Use WrappedError to filter duplicates
Switch from StringError to WrappedError. Errors of the form "Prefix:
Error" can now be filtered out based on the underlying error while
preserving distinct prefixes, resulting in clearer llvm-readobj output.
py-json5: updated to 0.14.0
0.14.0 (2026-03-27) This is really just a dependency bump release.
No (non-test) code changes.
Upgraded to latest packages for dev dependencies
Silenced a couple of warnings from the latest pylint where it can't deal with both unreachable code and a bad return value.
[FunctionAttrs] Don't infer noundef when return has nofpclass (#191822)
- Fixes: #191338
nofpclass violations on a return produce poison.
Poison returns marked noundef are UB.
This turns off noundef inference when nofpclass attributes are present.

[mlir][vector] Fold vector extract from insert when trailing unit dims (#192109)
Upstreamed from https://github.com/iree-org/iree/pull/23789
Folds vector.extract from vector.insert when the extract position is a
prefix of the insert position and the remaining (un-indexed) dimensions
of the extracted sub-vector are all size 1. In that case the extracted
value is fully determined by the inserted value.
Example:
%ins = vector.insert %s, %v [3, 0] : f32 into vector<16x1xf32>
%ext = vector.extract %ins [3] : vector<1xf32> from vector<16x1xf32>
folds to:
%ext = vector.broadcast %s : f32 to vector<1xf32>

[Clang][Hexagon] Use --cstdlib flag to choose Picolibc (#183257)
Update the Hexagon toolchain to use --cstdlib flag to allow users to
choose Picolibc as the C library.
This allows proper selection of C library when targeting
Hexagon environments.

[GlobalISel] Fix getShuffleDemandedElts input lanes in computeKnownFPClass (#192288)
The number of lanes needs to be for the input type, not the return, as
they can be different in GISel. This prevents an assert about invalid
shuffle mask constant from getShuffleDemandedElts.

[CIR] Implement LValue InitListExpr and FunctionalCastExpr lowering (#192298)
First, this fixes the InitListExpr lowering. This copies the same
implementation from classic-codegen, and adds some tests (this is
otherwise untested in classic codegen?).
Second, while I was writing tests for the above, I accidented into the
FunctionalCastExpr, which just calls emitCastLValue, so this fixes that
as well.
