[PGO][ICP] Prevent indirect call promotion to functions with incompatible target features (#192142)
Profile-driven indirect call promotion was promoting indirect calls to
functions requiring advanced CPU features (e.g., AVX512) even when the
caller function did not support those features. When these promoted
calls were subsequently inlined, it could lead to invalid IR and
backend crashes during instruction selection because the target CPU
could not handle the advanced instructions.
This patch addresses the issue by adding a target feature
compatibility check to `llvm::isLegalToPromote` in
`CallPromotionUtils.cpp`. If the callee requires target features
(prefixed with `+`) that are not present in the caller's target
features, the promotion is skipped. By centralizing this check in
`isLegalToPromote`, we protect all passes relying on this utility
(such as `SampleProfileLoader` and `IndirectCallPromotion`) from
promoting to incompatible targets. This also prevents incorrect
inlining of `always_inline` functions that would otherwise be promoted
via indirect calls and then inlined.

[MLIR] Add HasAncestor op trait (#195447)
Add HasAncestor/AncestorOneOf traits that verify an operation has a
specific ancestor anywhere in the parent chain, unlike HasParent which
only checks the immediate parent.
bsdinstall: Always use pkg.FreeBSD.org
The FreeBSD-base bits are accessible via pkg.FreeBSD.org, even for
releases, so there is no need to point at pkgbase.FreeBSD.org.

ccache: updated to 4.13.6
Ccache 4.13.6
Bug fixes and improvements
Fixed a potential manifest/result cache key collision in MSVC depend mode when compiling a source file with no included files.
Improved robustness when parsing cache entry data structures.
Test improvements
Changed the remote_helper test suite to skip gracefully when the storage test helper is unavailable, avoiding failures when testing a system-installed ccache.
[orc-rt] Change SPS controller-interface naming conventions. (#195614)
This commit makes two changes to the naming conventions for SPS CI
symbols:
1. The orc_rt_sps_ci_ prefix is replaced with orc_rt_ci_sps_ (for SPS
wrapper functions) and orc_rt_ci_ (without the "sps_" suffix) for data
symbols.
2. The _sps_wrapper suffix is dropped from wrapper functions, since the
prefix now distinguishes between SPS-wrappers and data symbols.

audio/fasttracker2: Update to 2.19
Changes since 2.18:
v2.19 - 03.05.2026
* Set audio input/output device to default during config reset
* If audio input device was set to default, properly open default
audio input device before sampling audio.
In pmap_bootstrap1(), check to see if FIXEDVA entries in machine_bootmap[]
are covered by any existing page table range, and if not, allocate additional
page table ranges to cover them.
This does not impact the one current user of FIXEDVA -- hp300 -- which
uses it to map the last page of RAM VA==PA. In the hp300 case, this
was already covered by the PTs that map the alternate SYSMAP_VA that
the hp300 uses (precisely because it needs the last VA==PA mapping).
This will eventually be used to map the I/O region VA==PA for mac68k.
Normally, we might otherwies use a TT register for that, but mac68k
runs on 68020s, so we cannot.

openssl: centralize speed benchmark timer handling
The speed benchmark currently arms alarm() from print_message() and
pkey_print_message(), making the output helpers also control benchmark
lifetime. This hidden coupling makes the code harder to maintain and led to
missing alarm cleanup on Windows, as reported in #1245.
Move alarm setup and run-state initialization into speed-specific timer
helpers so benchmark timing is controlled explicitly at the start and stop
points.

[MLIR][Python] Add `ConditionallySpeculatable` interface and `Pure` specifier (#195505)
This PR brings two features: the `ConditionallySpeculatable` op
interface and the `Pure` specifier for Python-defined ops.
The result is that you can mark an op as pure like:
```python
class PureOp(
TestPure.Operation,
name="pure",
traits=[Pure] # just like in the ODS!
):
a: Operand[IntegerType[32]]
b: Operand[IntegerType[32]]
res: Result[IntegerType[32]] = infer_result()
```
Then this op is both `NoMemoryEffect` and `AlwaysSpeculatable`.

[IR] Add elementwise modifier to atomicrmw (#189517)
This PR implements the IR side modifications of [[RFC] Add elementwise
modifier to atomicrmw](https://discourse.llvm.org/t/rfc-add-elementwise-modifier-to-atomicrmw/90134).
Design Decisions:
- In the IR, the current atomicrmw record layout looks like: [ptrty,
ptr, valty, val, operation, vol, ordering, syncscope, align]. To encode
elementwise, I decided to pack it into the operation field, which also
contains the math op (i.e. fadd, fmin, add etc...). I could have changed
the record structure, but that would be slightly more complicated.
- elementwise vector atomics can be vectors of integers because we can always scalarize legally
- elementwise vector atomics need to have power of 2 size. We can potentially remove this restriction later.

[compiler-rt] Add MSVC CRT flags to ASan coverage test (#195719)
The ASan coverage test also links clang_rt.profile because it uses
-coverage. On Windows MSVC, this can fail if the test is linked with the
static CRT but clang_rt.profile was built with the dynamic CRT.
For example, a profile runtime that uses /MD may reference DLL CRT
symbols
such as __imp_* symbols. Add the same dynamic CRT flags directly to this
one test on Windows MSVC so it keeps linking when clang_rt.profile
changes.
