[IR] handle oversized constant alloca counts in getAllocationSize (#204540)
AllocaInst::getAllocationSize() unconditionally calls getZExtValue() for
array allocas, which asserts when the constant element count is wider
than 64 bits.
Use tryZExtValue() when reading the constant array size instead. If the
count cannot be represented in uint64_t, return std::nullopt rather than
asserting, matching the existing contract.

[X86] combineX86ShufflesRecursively - delay widening shuffle inputs. NFC. (#204931)
Perform resolveTargetShuffleInputsAndMask earlier as widening shouldn't
merge any inputs (we canonicalize small shuffle inputs earlier).
We should be able to move the widenSubVector calls inside
combineX86ShuffleChain in a future commit, but this patch should be NFC.
Convert support plugin to typesafe pattern
## Context
The support plugin was an old-style dict-based `ConfigService`. This converts it to the typesafe pattern: a lean `GenericConfigService[SupportEntry]` service class delegating to a `ConfigServicePart`, with `generic = True`, `check_annotations=True` on every public method, and typed `call2` for same-process calls.
## Solution
- **Package split**: `plugins/support.py` becomes `plugins/support/` with `__init__.py` (lean service), `config.py` (`SupportModel` + `SupportConfigServicePart` holding `do_update`/`validate`), and `execute.py` (the `post` helper plus the `similar_issues`/`new_ticket`/`attach_ticket` logic as `ServiceContext`-typed functions).
- **API models**: decoupled `SupportAttachTicketArgs` from `@single_argument_args` into an explicit `SupportAttachTicket` inner model plus a plain wrapper (wire shape unchanged) so the method param can be annotated and field-accessed under `check_annotations`; exported every directly-imported model in `__all__`.
- **Registration**: registered the service in `main.py`'s `ServiceContainer` and added the plugin dir to `mypy.yml`.
- **Internal consumers**: `alert/source/proactive_support.py`, `alert/runtime.py`, and `truenas/tn.py` now use attribute access on the returned `SupportEntry` and typed `call2`/`context.call2` (constructing `SupportNewTicketEnterprise`) instead of dict access and string `middleware.call`.
The public wire shape is unchanged; live verification on the test VM confirmed read-only outputs, the update round-trip, the required-field validation path, and the ProactiveSupport alert consumer all behave identically to before.

Apply ruff formatting to new support package files
## Context
ruff's `format --diff` CI check only runs on git-added files and, with no quote-style configured, enforces its default (double quotes), so the newly added `support/` package needs reformatting once committed.
## Solution
Ran `ruff format` on the three new files in `plugins/support/`; pure style changes (quote style and call-argument wrapping), no logic changes.
libc/dbm: Differentiate between uninitialized and end-of-db cursors
Commit `3a686b851f8f` fixed a `dbm_nextkey` edge case when using
the function after reaching the end of the database, but it inadvertently
broke the following `R_NEXT` behaviour:
"If the cursor is not yet set, this is the same as the R_FIRST flag."
Fix this by adding a new cursor constant that allows us to differentiate
between an unset cursor and a cursor that overflowed.

[Reassociate] Distribute multiply over add to enable factorization (#178201)
### This patch improves ReassociatePass to handle patterns like:
(x*C1) - ((y+x)*C2) → x*(C1-C2) - (y*C2)
The optimization consists of two changes:
1. Distribution pre-processing: Transform (A+B)*C → A*C + B*C when:
- The add has exactly one use (avoids code bloat)
- Both add operands are non-constant (avoids unprofitable cases)
This exposes common factors that would otherwise be hidden inside
the addition, enabling subsequent factorization.
2. Factorization heuristic: Prefer extracting non-constant factors
(Instructions/Arguments) over constant factors when occurrence
counts are equal. This enables better constant folding opportunities.
Note: undef is excluded from this preference to maintain existing
