[dsymutil] Make --linker explicit in every test (#195293)
Pass `--linker classic` or `--linker parallel` on every `dsymutil`
invocation instead of relying on the implicit default. This preserves
the existing coverage in preparation for toggling the default in the
future.
Tests previously exercising only one linker now mirror the RUN block for
the other, sharing FileCheck prefixes. Not all tests are compatible, and
I've added a FIXME to make them easy to spot.
clang: Stop using replace_extension when there's no extension (#195335)
The offload case is building a fresh filepath and there's no file
extension to replace. Just directly append the file extension to avoid
clobbering part of the path name if the triple contains a period.
Avoids confusing test updates in future triple patch.
namei: Preserve ABI root for absolute symlinks before fallback
D40479 changed namei() so that an absolute symlink target
encountered during an ABI-root lookup restarts from the native root.
This helps the native fallback case, but it also makes successful
lookups inside an ABI root escape that root while following absolute
symlinks.
Only switch absolute symlink lookup to the native root after namei()
is already in the restarted/native fallback pass.
Do not mark the lookup as restarted merely because an absolute
symlink was encountered while still resolving inside the ABI root.
This preserves the intended native fallback behavior while keeping
absolute symlinks within a successfully resolved ABI-root path in
the ABI namespace.

[flang][OpenMP] Support loop-associated metadirective variants (part 3)
Enable metadirective lowering for loop-associated variants such as
`do`, `simd`, `parallel do`, and `do simd`.
When a metadirective resolves to a loop-associated directive, the
sibling DO evaluation is spliced into the metadirective's evaluation
list so existing loop lowering finds it. Loop IV data-sharing
attributes are marked at lowering time since semantic analysis cannot
know which variant will be selected. The DataSharingProcessor is also
extended to handle spliced evaluations.
This patch is part of the feature work for #188820 and stacked on top
of #194424.
Assisted with copilot and GPT-5.4
futex: Drop CLONE_THREAD requirement for private default hash alloc
Currently need_futex_hash_allocate_default() depends on strict pthread
semantics, abusing CLONE_THREAD. This breaks the non-concurrency
assumptions when doing the mm->futex_ref pcpu allocations, leading to
bugs[0] when sharing the mm in other ways; ie:
BUG: KASAN: slab-use-after-free in futex_hash_put
... where the +1 bias can end up on a percpu counter that mm->futex_ref
no longer points at.
Loosen the check to cover any CLONE_VM clone, except vfork(). Excluding
vfork keeps the existing paths untouched (no overhead), and we can't
race in the first place: either the parent is suspended and the child
runs alone, or mm->futex_ref is already allocated from an earlier
CLONE_VM.

security/libtatsu: initial import of package
Packaged in wip by wiz
Library handling the communication with Apple's Tatsu Signing Server (TSS).
This library is part of the libimobiledevice project. The main purpose of
this library is to allow creating TSS request payloads, sending them to
Apple's TSS server, and retrieving and processing the response.
The code was originally part of idevicerestore and has been split out to
its own library, while obviously idevicerestore will remain the main
consumer.
[llubi][NFC] Fix build with old GCC (#195327)
Using old GCC (7.5 in this case), we get a compile error about not being
able to deduce the template paramerter:
```
/llvm/llvm/tools/llubi/lib/Interpreter.cpp:770:14: error: no viable constructor or deduction guide for deduction of template arguments of 'std::vector'
770 | return std::vector(Vec.begin() + Offset, Vec.begin() + Offset + DstSize);
```
The error was introduced in
https://github.com/llvm/llvm-project/pull/194345.
Just specify the element type.

comms/libusbmuxd: import libusbmuxd-2.1.1 from wip
This project is a client library to multiplex connections from and to iOS
devices alongside command-line utilities. It is primarily used by
applications which use the libimobiledevice library to communicate with
services running on iOS devices.
The library does not establish a direct connection with a device but
requires connecting to a socket provided by the usbmuxd daemon.
The usbmuxd daemon is running upon installing iTunes on Windows and Mac OS
X. The libimobiledevice project provides an open-source reimplementation of
the usbmuxd daemon to use on Linux or as an alternative to communicate with
iOS devices without the need to install iTunes.

When a metadirective resolves to a loop-associated directive, the
sibling DO evaluation is spliced into the metadirective's evaluation
list so existing loop lowering finds it. Loop IV data-sharing

The DataSharingProcessor is extended to handle spliced evaluations:
the symbol visitor walks nested parse trees, symbol collection
includes nested evaluations, scope resolution walks ancestor scopes,
and lastprivate copy-back handles symbols without HostAssocDetails.

- Target constructs selected by metadirective (requires host-eval)
[libc] Implement sys/personality.h (#195065)
Added the personality() syscall wrapper, which sets or queries the
process execution domain. The function signature follows the Linux man
page: int personality(unsigned long persona).
New files:
* libc/include/sys/personality.{yaml,h.def}
* libc/src/sys/personality/ (implementation + linux/ syscall)
* libc/test/src/sys/personality/ (unit tests)
Registered the entrypoint and header for x86_64, aarch64, riscv, and
arm. The implementation includes <linux/personality.h> for the
kernel-defined constants (PER_LINUX, ADDR_NO_RANDOMIZE, etc.) following
the same pattern as sys/prctl.h.

[AMDGPU] Optimize DPP for fmin/fmax functions (#195282)
Summary:
These functions currently don't simplify in the optimistic (no-NaN) case
as their identity is not recognized by the optimizer. This PR simply
adds the -inf,+inf checks so these combine without the intermediate
moves.
net/libnfs: Import libnfs-6.0.2
Packaged in wip by PHO, with some modifications by vins.
LIBNFS is a client library for accessing NFS shares over a network.
LIBNFS offers three different APIs, for different use:
1, RAW: A fully async low level RPC library for NFS protocols
2, NFS ASYNC: A fully asynchronous library for high level vfs functions
3, NFS SYNC: A synchronous library for high level vfs functions
Fix dynamic metadirective candidate selection
- Use one scored candidate path for static and dynamic metadirective variants.
- Dynamic user conditions are statically filtered and scored using their
non-user traits, then guarded at runtime with fir.if.
- Keeps construct/device/implementation traits enforced for dynamic
candidates and lets higher-scored static candidates beat lower-scored dynamic
candidates.
- Add regressions for construct mismatch, score ordering, and
implicit-nothing tie-breaking.
