[LV] Add select instruction to VPReplicateRecipe::computeCost (#186825)
I've added the Instruction::Select opcode to the existing list of
opcodes that call getCostForRecipeWithOpcode. There are currently 5
tests that ask for the cost of the select:
Transforms/LoopVectorize/AArch64/widen-gep-all-indices-invariant.ll
Transforms/LoopVectorize/first-order-recurrence-with-uniform-ops.ll
Transforms/LoopVectorize/narrow-to-single-scalar.ll
Transforms/LoopVectorize/replicate_fneg.ll
Transforms/LoopVectorize/single-scalar-cast-minbw.ll
The fact they all pass with this change is hopefully proof enough that
the costs are correct.
libclc: Use small trig reduction for nan (#186983)
Nan should work on either path, but the small reduction
path is smaller. There's also possible codegen benefits to
knowing the large reduction will not need to handle nans.

libclc: Move edge case handling of trig functions (#186429)
The explicit handling of nan is unnecessary. Clamp infinities
to nan at the input. This allows optimizations of the following
implementation code to take advantage of the knowledge that it
does not need to handle infinities.
[VPlan] Factor collectGroupedReplicateMemOps (NFC) (#186820)
Factor out a collectGroupedReplicateMemOps from
collectComplementaryPredicatedMemOps, so it can be re-used in other
places.
[OpenMP][OMPT] Add missing `error` entry to device tracing record union (#185683)
While `omp-tools.h` already includes the `ompt_record_error_t` struct,
the corresponding union entry was missing from `ompt_record_ompt_t`.
This commit adds the missing entry.
Note that this does not enable any functionality for device tracing
records.
This only aligns the struct with OpenMP v5.1 and newer. OpenMP v5.0 did
not contain the `error` directive.

[DA] Add test for the Weak Crossing SIV test misses dependency (NFC) (#186355)
Add a test case where the value of `Delta` in the Weak Crossing SIV test
becomes the signed minimum, causing the test to miss the dependency.
[clang][ssaf] Add --ssaf-list-{extractor,format} flags (#185428)
These flags only work with the `clang` driver.
The `cc1` driver would ignore these flags.
Probably it could be implemented differently, but it's already better
than having nothing.
[llvm-link] Add more detail to `--internalize` description (#170397)
While the functionality of this flag is obvious in the implementation,
tool users may not know what it does with the short description
provided. Notably, it is not obvious from the short description that:
* Functions provided will be converted to internal linkage (and thus
discarded if unused) even if unreferenced.
* Functions in the first file will not be internalized, even if
referenced by a later one.
The Rust for Linux project has [found use for this
flag](https://lore.kernel.org/all/20251202-inline-helpers-v1-0-879dae33a66a@google.com/)
to support inlining `static inline` functions in C into code compiled by
Rust when `rustc` and `clang` share a LLVM.
[clang][PAC] add support for options parameter to __ptrauth
This PR adds support for an 'options' parameter for the __ptrauth
qualifier.
The initial version only exposes the authehntication modes:
* "strip"
* "sign-and-strip"
* "sign-and-auth"
We also support parsing the options but not yet the implementation
* "isa-pointer"
* "authenticates-null-values"
The initial support for authentication mode controls exist to support
ABI changes over time, and as a byproduct support basic initial tests
for option parsing.
Reland "[lldb] Initial plugin and test for SymbolLocatorSymStore" (#185658)
Minimal infrastructure for a the SymbolLocator plugin that fetches debug
info from Microsoft SymStore repositories. This can work cross-platform
and for various debug info formats in principle, but the current plan is
focussed on PE/COFF on Windows with debug info in PDB files. Once we
have a stable first version, we'd like to add features like download,
environment variables, caching and progress feedback for users.
SymbolVendorPECOFF was tailored towards DWARF debug info so far. I added
code to load the PDB path from the executable (it only checked
gnu_debuglink so far) and not bail out if DWARF sections are missing, so
that in the PDB case we still call AddSymbolFileRepresentation() in the
very end of CreateInstance().
The API test in this patch mocks the directory layout from SymStore, so
it doesn't depend on SymStore.exe from the Windows SDK. It runs on all
platforms that link debug info in a PDB file, which is still just
Windows, but it could be cross-platform in principle.
