Git commit 9410fc68c61057a493abd33c43fbcb8bae1f98e0 by GitHub (on behalf of Michael G. Kazakov) on 13/08/2026 at 11:13..
[libc++][pstl] Implementation of parallel uninitialized_default_construct, uninitialized_value_construct and uninitialized_fill (#214580)

This PR adds parallel versions of these functions:
- `std::uninitialized_default_construct`
- `std::uninitialized_default_construct_n`
- `std::uninitialized_value_construct`
- `std::uninitialized_value_construct_n`
- `std::uninitialized_fill`
- `std::uninitialized_fill_n`

They use parallel `for_each` under the hood and are effectively
one-liners, e.g.:
```c++
return ForEach()(policy, std::move(first), std::move(last), [&value](Ref element) {
    ::new (static_cast<void*>(std::addressof(element))) ValueType(value);
});
```

Fixes #134590.

Revert "[offload] Fix compatibility for level_zero 25.22.33944- #2142… (#216010)

…15 (#215977)"

This reverts commit 77c8ecd7a6b912b6c61665f623f864c4cba52a00.

Level zero approach to zex pointers is a little inconsistent and I need
to rework the PR. Some APIs such as
`zeCommandListAppendLaunchKernelWithArguments` would return `SUCCESS` on
older versions and provide a valid pointer to implemntation, but in more
recent versions of level zero you would get `ERR_INVALID_ARGUMENT`.

[RISCV] Fix prefetch ADDI-adjustment range upper bound (#215985)

SelectAddrRegImmLsb00000 folds a large constant offset into an ADDI plus
a simm12_lsb00000 prefetch immediate. The positive range [2017, 4065]
overflowed simm12 at the top end: CVal - 2016 reaches 2048/2049,
producing an invalid ADDI. Narrow it to 4063; 4064/4065 now fall through
to selectConstantAddr instead.

[APINotes] Strip selector volatile and nested nullability from parameter selectors (#215266)

Address @Xazax-hun's comments about volatile and nullability stripping
from
https://github.com/llvm/llvm-project/pull/213043#pullrequestreview-4830763715.

This strips top-level `volatile` like top-level `const` when building
`Where.Parameters` selector spellings, and recursively strips
nullability through pointer-like layers such as `int * _Nullable *
_Nullable`.

This is a prequel PR to
https://github.com/llvm/llvm-project/pull/213043.

[lldb-dap][NFC] Fix deprecated SB API usages (#216006)

lldb-dap has accumulated over time several calls to deprecated SB API
functions. Since #215818 we actually emit the missing deprecation
warnings which breaks the lldb-dap build with -Werror. This patch
replaces the deprecated functions with the equivalent non-deprecated
version.

Note that this patch is intentionally NFC and I just added TODOs for the
missing error handling.

[libc++][NFC] Update implementation strategy of the `operator()(I&& first, S last)` for `std::ranges::distance` (#215994)

This patch updates the implementation strategy for `ranges::distance(I&&
first, S last)` to match the exact wording from the Standard.

This implementation is NFC because the return type and the branching
condition will be the same after the change, and the tests present in
`libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/iterator_sentinel.pass.cpp`
are already covering the scenarios for such change.

[clang][LoongArch] Match GCC ABI handling of integer complex types (#215222)

GNU integer complex types such as `_Complex unsigned char` and `_Complex
unsigned short` were incorrectly recognized as eligible floating-point
ABI aggregates by `detectFARsEligibleStructHelper`. When used as a
member of a structure, this caused the real and imaginary parts to be
expanded into separate general-purpose argument registers.

Integer complex types are not floating-point complex types and should be
handled as ordinary aggregates. Restrict the complex-type expansion path
to elements with real floating-point types, allowing small integer
complex aggregates to be packed into a single general-purpose register,
consistent with GCC.

[lldb][test][lldb-dap] Use program path in TestDAP_runInTerminal.py (#216009)

On Linux if you run `INVALIDPROGRAM` it will look in PATH for it.
lldb-dap runs the program using execvp which has special behaviour for
the case where an entry in path cannot be accessed.

https://linux.die.net/man/3/execvp

> If permission is denied for a file (the attempted execve(2)
> failed with the error EACCES), these functions will continue
> searching the rest of the search path. If no other file is
> found, however, they will return with errno set to EACCES.

We have a downstream bot where the PATH was:
PATH=/root/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

The buildbot user is not root, so /root/.cargo/bin was not readable, and
so one test failed on this machine:
```
FAIL: test_FakeAttachedRunInTerminalLauncherWithInvalidProgram (TestDAP_runInTerminal.TestDAP_runInTerminal)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/davspi01/llvm-project/lldb/test/API/tools/lldb-dap/runInTerminal/TestDAP_runInTerminal.py", line 231, in test_FakeAttachedRunInTerminalLauncherWithInvalidProgram
    self.assertIn(
AssertionError: 'No such file or directory' not found in '{"kind":"error","value":"Permission denied"}\n'
```
It's saying permission denied for the PATH entry, rather than could not
find the program file.

You can reproduce this locally with:
$ mkdir /tmp/lldb-no-search
$ chmod 000 /tmp/lldb-no-search
$ env PATH="/tmp/lldb-no-search:$PATH" ./bin/lldb-dotest -p
TestDAP_runInTerminal.py

To fix this, I've changed the test case to use the full path to the
(non-existent) program file. As this test should not be depending on
PATH anyway.
