[flang][NFC] Converted five tests from old lowering to new lowering (part 4) (#174906)
From this point on, the conversion is done to HLFIR, not to FIR.
Tests converted in Lower: allocatables.f90,
allocate-source-pointers.f90, array-constructor-2.f90,
array-elemental-calls-3.f90, array-elemental-calls.f90
[lldb] Fix typed commands not shown on the screen (#174216)
The cause is that in `python3.14`, `fcntl.ioctl` now throws a buffer
overflow error
when the buffer is too small or too large (see
https://github.com/python/cpython/pull/132919). This caused the Python
interpreter to fail terminal detection and not properly echo user
commands back to the screen.
Fix by dropping the custom terminal size check entirely and using the
built-in `sys.stdin.isatty()` instead.
Fixes #173302
[llvm-readobj] Dump callgraph section info for ELF (#157499)
Introduce a new flag `--call-graph-info` which outputs callgraph ELF
section information to the console as a text output or as JSON output.
Attributor: Set up full SimplifyQuery for nofpclass (#174928)
This enables assumes to work. Somehow the most obvious example
I could think of does not work (return of assumed argument).
The context instruction for the return seems to be off by one.
[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.
