Subject: [PATCH 02/41] [VPlan] Return cost of 0 for VPWidenCastRecipe without
underlying value.
In some cases, VPWidenCastRecipes are created but not considered in the
legacy cost model, including truncates/extends when evaluating a reduction
in a smaller type. Return 0 for such casts for now, to avoid divergences
between VPlan and legacy cost models.
Fixes https://github.com/llvm/llvm-project/issues/113526.

Subject: [PATCH 07/41] [libc++] Remove obsolete Solaris and Newlib support for
locales (#113721)
The solaris header file doesn't even exist, so that's definitely dead
code. The newlib header is empty, which means that localization can't
work on that platform. If someone is using libc++ with Newlib, they must
be providing LIBCXX_HAS_NO_LOCALIZATION today for anything to work, so
that header is basically dead code as well.

Subject: [PATCH 08/41] [WebAssembly] Enable nontrapping-fptoint and
bulk-memory by default. (#112049)
We were prepared to enable these features [back in February], but they
got pulled for what appear to be unrelated reasons. So let's have
another try at enabling them!
Another motivation here is that it'd be convenient for the [Lime1
proposal] if "lime1" is close to a subset of "generic" (missing only
for extended-const).
[back in February]:
https://github.com/WebAssembly/tool-conventions/issues/158#issuecomment-1931119512
[Lime1 proposal]: https://github.com/llvm/llvm-project/pull/112035

+Disabling and suppressing
+-------------------------
-In some circumstances, you may want to suppress error reporting in a specific scope.
+There are multiple ways to disable error reporting when using RealtimeSanitizer.
-In C++, this is achieved via ``__rtsan::ScopedDisabler``. Within the scope where the ``ScopedDisabler`` object is instantiated, all sanitizer error reports are suppressed. This suppression applies to the current scope as well as all invoked functions, including any functions called transitively.
+In general, ``ScopedDisabler`` should be preferred, as it is the most performant.

Each call to ``__rtsan_disable()`` must be paired with a subsequent call to ``__rtsan_enable()`` to restore normal sanitizer functionality. If a corresponding ``rtsan_enable()`` call is not made, the behavior is undefined.

+
+Suppressions specified in this file are one of two flavors.
+
+``function-name-matches`` suppresses reporting of any intercepted library call, or function marked ``[[clang::blocking]]`` by name. If, for instance, you know that ``malloc`` is real-time safe on your system, you can disable the check for it via ``function-name-matches:malloc``.
+
+``call-stack-contains`` suppresses reporting of errors in any stack that contains a string matching the pattern specified. For example, suppressing error reporting of any non-real-time-safe behavior in ``std::vector`` may be specified ``call-stack-contains:std::*vector``. You must include symbols in your build for this method to be effective, unsymbolicated stack traces cannot be matched. ``call-stack-contains`` has the highest run-time cost of any method of suppression.
+
+Patterns may be exact matches or are "regex-light" patterns, containing special characters such as ``^$*``.
+
+The number of potential errors suppressed via this method may be seen on exit when using the ``print_stats_on_exit`` flag.

Subject: [PATCH 10/41] [clang][modules] Only serialize info for
locally-included headers (#113718)
I noticed that some PCM files contain `HeaderFileInfo` for headers only
included in a dependent PCM file, which is wasteful.
This patch changes the logic to only write headers that are included
locally. This makes the PCM files smaller and saves some superfluous
deserialization of `HeaderFileInfo` triggered by
`Preprocessor::alreadyIncluded()`.

Subject: [PATCH 13/41] [SHT_LLVM_BB_ADDR_MAP][AsmPrinter] Add none and all
options to PGO Map (#111221)
This patch adds none and all options to the -pgo-analysis-map flag,
which do basically what they say on the tin. The none option is added to
enable forcing the pgo-analysis-map by overriding an earlier invocation
of the flag. The all option is just added for convenience.

Subject: [PATCH 17/41] X86: Improve cost model of fp16 conversion (#113195)
Improve cost-modeling for x86 __fp16 conversions so the SLPVectorizer
transforms the patterns:
- Override `X86TTIImpl::getStoreMinimumVF` to report a minimum VF of 4 (SSE
register can hold 4xfloat converted/stored to 4xf16) this is necessary as
fp16 stores are neither modeled as trunc-stores nor can we mark direct Xxfp16
stores as legal as we generally expand fp16 operations).
- Add missing cost entries to `X86TTIImpl::getCastInstrCost`
conversion from/to fp16. Note that conversion from f64 to f16 is not
supported by an X86 instruction.

Subject: [PATCH 19/41] [libc++] Bump `__cpp_lib_optional` and
`__cpp_lib_variant` (#113650)
In C++20 mode, `__cpp_lib_optional` and `__cpp_lib_variant` should be
`202106L` due to DR P2231R1.
In C++26 mode, `__cpp_lib_variant` should be bumped to `202306L` due to
P2637R3.
- Clang 16/17 shouldn't get this bumping (as member `visit` requires
explicit object parameters), but it's very tricky to make the bumping
conditionally enabled. I _hope_ unconditionally bumping in C++26 will be
OK for LLVM 20 when the support for Clang 17 is dropped.

Subject: [PATCH 21/41] [mlir] [memref] add more checks to the
memref.reinterpret_cast (#112669)
Operation memref.reinterpret_cast was accept input like:
%out = memref.reinterpret_cast %in to offset: [%offset], sizes: [10],
strides: [1]
: memref<?xf32> to memref<10xf32>
A problem arises: while lowering, the true offset of %out is %offset,
but its data type indicates an offset of 0. Permitting this
inconsistency can result in incorrect outcomes, as certain pass might
erroneously extract the offset from the data type of %out.
This patch fixes this by enforcing that the return value's data type
aligns
with the input parameter.

Subject: [PATCH 25/41] [ADT] Use data() and size() within StringRef (NFC)
(#113657)
This patch uses data() and size() within StringRef instead of Data and
Length. This makes it easier to replace Data and Length with
std::string_view in the future, which in turn allows us to forward
most of StringRef functions to the counterparts in std::string_view.

Subject: [PATCH 29/41] [MLIR][NVGPU] Fix nvgpu_arrive syntax in
matmulBuilder.py (#113713)
This patch updates the syntax for nvgpu_arrive Op
in matmulBuilder.py. This fixes the compilation
error for this test.
For the warp-specialized matmul_kernel implementation,
removing the WaitGroupSyncOp (after the mma-main-loop)
fixes the hang observed.
With these two fixes, the test compiles and
executes successfully on an sm90a machine.

Subject: [PATCH 30/41] [libc++][test] Make macro detection more friendly to
MSVC (#113633)
MSVC STL's test suite is a bit nervous about replacing non-macro-defined
identifiers with `0` (see also
https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-4-c4668?view=msvc-170).
On MSVC (and MS-compatible mode of other compilers), `long double` has
the same format (IEEE-754 binary64) as `double`, so it should be OK to
define `TEST_LONG_DOUBLE_IS_DOUBLE` when `_MSC_VER` is defined. Such
detection should be performed first.

Subject: [PATCH 34/41] [rtsan][llvm][NFC] Rename sanitize_realtime_unsafe attr
to sanitize_realtime_blocking (#113155)
# What
This PR renames the newly-introduced llvm attribute
`sanitize_realtime_unsafe` to `sanitize_realtime_blocking`. Likewise,
sibling variables such as `SanitizeRealtimeUnsafe` are renamed to
`SanitizeRealtimeBlocking` respectively. There are no other functional
changes.
# Why?
- There are a number of problems that can cause a function to be
real-time "unsafe",
- we wish to communicate what problems rtsan detects and *why* they're
unsafe, and
- a generic "unsafe" attribute is, in our opinion, too broad a net -
which may lead to future implementations that need extra contextual
information passed through them in order to communicate meaningful
reasons to users.
- We want to avoid this situation and make the runtime library boundary
API/ABI as simple as possible, and
- we believe that restricting the scope of attributes to names like
`sanitize_realtime_blocking` is an effective means of doing so.
We also feel that the symmetry between `[[clang::blocking]]` and
`sanitize_realtime_blocking` is easier to follow as a developer.
# Concerns
- I'm aware that the LLVM attribute `sanitize_realtime_unsafe` has been
part of the tree for a few weeks now (introduced here:
https://github.com/llvm/llvm-project/pull/106754). Given that it hasn't
been released in version 20 yet, am I correct in considering this to not
be a breaking change?

Transfer{Read|Write}DropUnitDimsPattern patterns (#112394)
Updates `TransferWriteDropUnitDimsPattern` and
`TransferReadDropUnitDimsPattern` to inherit from
`MaskableOpRewritePattern` so that masked versions of
xfer_read/xfer_write Ops are also supported:
```mlir
%v = vector.mask %mask {
vector.transfer_read %arg[%c0, %c0, %c0, %c0], %cst :
memref<1x1x3x2xi8, strided<[6, 6, 2, 1], offset: ?>>, vector<3x2xi8>
} : vector<3x2xi1> -> vector<3x2xi8>
```

Subject: [PATCH 36/41] [libc++] Split Apple and Freebsd locale support into
their own headers (#113737)
For now these headers don't provide much benefit, however as we refactor
the locale base API they will provide a location to specify the
localization interface on these platforms.

Subject: [PATCH 39/41] [LV][VPlan] Use VF VPValue in VPVectorPointerRecipe
(#110974)
Refactors VPVectorPointerRecipe to use the VF VPValue to obtain the
runtime VF, similar to #95305.
Since only reverse vector pointers require the runtime VF, the patch
sets VPUnrollPart::PartOpIndex to 1 for vector pointers and 2 for
reverse vector pointers. As a result, the generation of reverse vector
pointers is moved into a separate recipe.
