ministat: parse comma used as decimal delimiter
This allows to use output of '/usr/bin/time -ao foo' as direct input to
ministat(1).
While here make diagnostic message more verbose.
witness: fix operation without WITNESS_SKIPSPIN
Since malloc(9) even with M_NOWAIT is forbidden when we hold a spinlock,
we can't print detailed lock tree as the operation tries to allocate
memory.

[clang][CodeGen][X86_64] Honor per-function AVX ABI in C/C++ call paths, maintain old psABI for PlayStation. (#193298)
Fixes https://github.com/llvm/llvm-project/issues/64706
Wire per function x86 AVX ABI level into CodeGen arrangement methods so
__attribute(__target("avx"))) / __attribute(__target("avx512f"))) on
methods, ctors, and free-functions affects ABI lowering consistently.
Specifically:
- Added X86AVXABILevel member to CGFunctionInfo.
- Populated X86AVXABILevel member in CGFunctionInfo objects via
arrangement methods declared in CodeGenTypes.h.
- Respect CGFunctionInfo AVX Level in X86_64ABIInfo::computeInfo.
- Add/extend regression tests for:
- free-function target-attribute AVX ABI lowering
- C++ method/ctor target-attribute AVX ABI lowering
- PS4/PS5 legacy ABI behavior (no per-function AVX ABI change)

[AArch64][SVE] Support lowering masked loads/stores of <4 x bf16> and <8 x bf16> (#208744)
Add support for lowering masked loads/stores of <4 x bf16> and <8 x
bf16> when target features contain "+sve" and "+bf16".
Fixes: #201149
Don't bother with the "no disk label" message. It's not particularly
useful, and is downright confusing if the disk has some other sort of
partition scheme (such at GPT).
Add expression validation tests for DW_OP_swap (#210184)
Add DIExpression validation tests for DW_OP_swap that we noticed were
missing. The tests are based on the existing expression tests for
DW_OP_stack_value.
Tested via make check.

[lldb/script] Migrate frame recognizers onto ScriptedPythonInterface (#209805)
Give `frame recognizer add -l` a formal
ScriptedStackFrameRecognizerInterface, matching the architecture already
used by ScriptedProcess, ScriptedBreakpoint, etc.: a C++ interface
header, a Python-backed implementation built on
ScriptedPythonInterface's CreatePluginObject/Dispatch machinery,
PluginManager registration, and a generatable Python ABC template
(scripted_stackframe_recognizer.py).
get_recognized_arguments' documented contract returns a plain list of
lldb.SBValue (not an lldb.SBValueList), so it bypasses the generic
Dispatch<ValueObjectListSP>() extractor and calls the SWIG bridge
directly, matching the legacy behavior exactly.
ScriptedStackFrameRecognizer now holds a single interface object created
once in its constructor and reused across every RecognizeFrame() call,
same lifecycle as before.

[ThreadSafety] Add two-state semantics for handleCall in beta mode
Previous contributions added alias analysis and strengthened soundness by
invalidating out-parameters in beta mode. The latter feature introduced a
distinction between the contexts before and after a function call, because the
invalidation assumes that an argument passed by pointer or reference may be
changed by the function.
This requires two-state semantics for handling function attributes.
Specifically, AcquireCapability and AssertCapability, which both ensure that
some locks are held after the call, should be associated with the post-state.
Other function attributes, like RequireCapability or ReleaseCapability, are
associated with the pre-state.
This commit implements these semantics. This change only affects beta mode.
A previous discussion about these semantics:

[clang][ssaf] Add static-library create subcommand (#208799)
This change adds `clang-ssaf-linker static-library create` for bundling
TU summaries into a StaticLibrary archive. The linker has been
refactored to dispatch on `cl::SubCommand`; invocations without a
subcommand still run the existing linker pipeline unchanged for backward
compatibility.
