[llubi] Return void for `InstExecutor::visit*` methods. NFC. (#181421)
The status is now maintained inside of `setResult` and other helper
functions. So we don't need to propagate the error.
This patch was part of https://github.com/llvm/llvm-project/pull/181393.
[clang][deps] Extract service config into a struct (#181405)
Adding new configuration knobs in the scanner is fairly painful now,
especially with a diverging downstream. This patch extracts what was
previously passed into the service constructor into a struct. This
encourages one knob customization per line, reduces difficult merge
conflicts, `/*ArgName=*/`-style comments with copy-pasted defaults, etc.
[RISCV] Combine ADDD(lo, hi, x, 0) -> WADDAU(lo, hi, x, 0). Combine WADDAU (WADDAU lo, hi, x, 0), y, 0 -> WADDAU lo, hi, x, y (#181396)
WADDAU is rd += zext(rs1) + zext(rs2)
If we only have 1 32-bit input can force rs2 to avoid zeroing the upper
part of a register pair to use ADDD.
Unfortunately, WADDAU clobbers rd so it might need a GPRPair copy
if we need the old value of rd. We might need to look into that in
the future. Maybe we could have convertToThreeAddress could turn
it back into ADDD+WADDU or ADDD+LI.

[VPlan] Compute NumPredStores for VPReplicateRecipe costs in VPlan.
Compute the number of predicated stores directly in VPlan instead of
using CM.useEmulatedMaskMemRefHack(), which will only account for the
number of predicated stores for the last VF the legacy cost model
considered.

[NFC][analyzer] Remove NodeBuilder::iterator (#181381)
This iterator class was used only once and even there it was easily
replaced by a more appropriate solution.
This commit is motivated by the fact that my recent commit
320d0b5467b9586a188e06dd2620126f5cb99318 turned
`IndirectGotoNodeBuilder` and `SwitchNodeBuilder` into subclasses of
`NodeBuilder` and those classes have their own (slightly more useful)
`::iterator`s with very different behavior.
[ASan][Windows] Fix false positive for zero sized rtl allocations (#181015)
This is a follow up to #155943
On Windows, ASan's allocator internally upgrades zero-size allocation
requests to size 1 (since malloc(0) must return a unique non-NULL
pointer). However, when the user queries the allocation size through
Windows heap APIs (RtlSizeHeap, HeapSize, \_msize, GlobalSize,
LocalSize), ASan reports the internal size (1) instead of the originally
requested size (0).
This causes false positive heap-buffer-overflow errors in a common
pattern:
```c++
void *buf = HeapAlloc(GetProcessHeap(), 0, 0);
SIZE_T size = HeapSize(GetProcessHeap(), 0, buf); // Returns 1, should be 0
if(size > 0) // could remove this and still be correct
memset(buf, 0, size); // ASan reports heap-buffer-overflow

[Support] Support 5-component VersionTuples (#181275)
LLDB parses compiler versions out of DW_AT_producer DWARF attributes
into a VersionTuple. The Swift compiler recently switched to 5-component
version numbers. In order to support this version scheme without growing
the size of VersionTuple, this patch dedicates the last 10 bits of the
build version to a 5th "sub-build" component. The Swift compiler
currently uses 1 digit for this and promises to never use more than 3
digits for the last 3 components.
This patch still leaves 6 decimal digits for the build component for
other version schemes.

[RFC][Docs][Clang][AMDGPU] Add AMDGPU builtins documentation
Add comprehensive documentation for AMDGPU target-specific builtins
(`AMDGPUBuiltins.rst`) covering argument semantics, restrictions, and
lowering notes for all builtin families.
This documentation was generated by AI (Claude) by cross-referencing:
- `clang/include/clang/Basic/BuiltinsAMDGPU.td` (builtin definitions)
- `llvm/include/llvm/IR/IntrinsicsAMDGPU.td` (intrinsic definitions)
- `clang/lib/Sema/SemaAMDGPU.cpp` (argument validation/constraints)
- `clang/lib/CodeGen/TargetBuiltins/AMDGPU.cpp` (lowering logic)
I did my best to proofread the parts I'm familiar with, but it would be greatly
appreciated if more people could help review it as well.

NAS-139300 / 26.0.0-BETA.1 / Add dataset and relative_path fields to share entries (#18021)
This represents the first change for
[NAS-137337](https://ixsystems.atlassian.net/browse/NAS-137337). We may
choose to do something similar for other services that use dataset
paths.
* Add "dataset" field which is calculated on create and update based on
"path"
* Add "relative_path" field which is calculated on create and update
based on "path"
* Keep "path" field to avoid concatenating the fields and prepending
"/mnt/" when the full path is required
* No extra mess in `extend` and `compress`
1. Alembic migration adds columns to all `SharingServiceTask` services.
2. migration/0018 attempts to populate the columns based on the existing
path fields.
3. `pool.import` and `pool.dataset.unlock` call hooks to query

timeout: Clean up
* Annotate logv() and fix format string bug.
* Don't reinvent str2sig(3).
* Reorganize kill_self() so we unblock signals as late as possible, and
use raise(2) instead of kill(2).
* Explicitly close unused pipe descriptors.
* Use correct type to collect result of read(2) and write(2).
* Compare return values to 0, not -1.
* Sort local variables according to style(9).
* Reduce unnecessary nesting.

diff: Tweak recursion tests
The -r flag is not required to compare two directories; it is only
required to compare them recursively, i.e. descend into their common
subdirectories. Adjust tests that use -r needlessly, and adjust the
dirloop test to verify that these two cases remain distinct.

diff: Tweak range of -C and -U arguments
POSIX uses the terms “positive decimal integer” for -C and “non-negative
decimal integer” for -U, which translates into lower bounds of 1 for -C
and 0 for -U.
POSIX does not specify a minimum upper bound for either mode, but as of
5fc739eb5949 both our backends support context sizes up to and including
INT_MAX, so use that.
Having had the opportunity to consult the Unix System Test Suite, the
diff test cases found therein happen to precisely match these bounds.
While here, switch to using strtonum() to parse numerical arguments, and
try to be more consistent in how we report usage errors.

[lldb/Breakpoint] Fix condition hash after updating condition text (#181409)
StopCondition::SetText was computing the hash from the moved-from text
parameter instead of the stored m_text member. After std::move(text),
the source parameter becomes empty, causing the hash to always be
computed from an empty string.
This caused breakpoint condition updates to fail silently. When a user
modified a condition (e.g., from "x == y" to "x > y"), the hash remained
unchanged. Breakpoint locations use this hash to detect when conditions
need re-evaluation, so with a stale hash they would continue using
cached state for the old condition, triggering at incorrect locations.
The patch fixes this issue by computing the hash from m_text after the
move operation, ensuring it reflects the actual stored condition text.
It also adds API test that updates a breakpoint condition and verifies
the new condition is properly evaluated.
