[flang] Do not error on constant nonzero UB in substring of ZLA (#174511)
A substring reference where the lower bound is higher than the upper
bound is defined in 9.4.1 to be zero-length.
Thus, a reference to a substring of a CHARACTER*(0) string such as
string(foo():2)
cannot be a compile-time error since we do not know the return value of
foo().
We also should not error if the lbound > ubound at compile time.
[LLDB][NativePDB] NFC: Add language-agnostic interface to PdbAstBuilder (#173111)
This change implements part of
https://discourse.llvm.org/t/rfc-lldb-make-pdbastbuilder-language-agnostic/89117,
the goal of which is make `PdbAstBuilder` language-agnostic.
It adds several new interface methods to `PdbAstBuilder` which allow
`SymbolFileNativePDB` to interact with it without using Clang-specific
types. These new methods would make up much of the interface of a future
abstract `PdbAstBuilder`. `SymbolFileNativePDB` is updated to use these.
The old Clang-specific methods were renamed if used by
`UdtRecordCompleter` or internally, or removed where possible.
[NFC][lldb] fix docstring indentation (#175042)
This patch fixes the indentation of 2 docstrings in
`TestDAP_runInTerminal.py`.
Running `black` on that file with the default settings causes this
change. `darker` does not seem to catch it.
This is a prelude to https://github.com/llvm/llvm-project/pull/174635.
[lldb] Nominate Charles Zablit and Nerixyz as Windows maintainers (#175035)
As the lead maintainer, I've been asked by the project council to
confirm that we have an up-to-date list of active maintainers for LLDB.
In light of that, I'd like to nominate Charles and Nerixyz as Windows
maintainers.
As a reminder, our community policies regarding the responsibilities of
maintainers can be found here:
https://llvm.org/docs/DeveloperPolicy.html#maintainers.
[compiler-rt] [Darwin] Add darwin-remote feature for remote darwin test targets (#174905)
Some tests are already supported on "remote" devices and simulators.
However, there is currently no way to distinguish a remote macOS host
from a local one.
This adds the darwin-remote feature which is common to all test targets
which use a wrapper script (e.g. iossim_run.py).

[AArch64] Add intra-block CSINC optimization to AArch64ConditionOptimizer (#173734)
This patch extends the AArch64ConditionOptimizer pass to handle CSINC
instructions within a single basic block, complementing the existing
cross-block branch optimization.
The optimization finds two CMP+CSINC pairs comparing the same register
with immediates differing by 1, and adjusts one comparison to enable CSE
to eliminate the redundant CMP instruction.
Example transformation:
```
cmp w8, #10
csinc w9, w0, w1, gt ; w9 = (w8 > 10) ? w0 : w1+1
cmp w8, #9 ; Removed by CSE after adjustment
csinc w10, w0, w1, gt ; w10 = (w8 > 9) ? w0 : w1+1
```
After optimization:

[SPIR-V] Add builtin/intrinsic for subgroup ballot (#174862)
Summary:
This patch adds an LLVM intrinsic and lowering for a subgroup ballot and
a corresponding clang builtin. This uses the already present support but
provides in a way accessible to other targets. With this and
https://github.com/llvm/llvm-project/pull/174655 we should be able to
most of the basic functions, like shuffling, active masks, and
reductions. More work will be needed for canonicalizing / exposing the
SPIR-V functions, but these are the fundamental builtins I need.
