[WebKit Checkers] Add alpha.webkit.UnborrowedLambdaCapturesChecker (#226288)
Like alpha.webkit.UnborrowedLocalVarsChecker, but for lambda captures.
This checker is pretty restrictive because, unlike a refcounted object,
a lifetime-dependent pointer/reference/view cannot be captured in an
escaping closure at all. Still, we permit capturing in a NOESCAPE
closure.
[CIR] Record -ffp-contract=fast as a per-op contract flag
Classic CodeGen stamps contract on floating-point instructions so a later
Standard-fusion backend can still form an FMA. CIR only fused within a
statement via cir.fmuladd, which dropped FFMA on the CUDA device default.

[clang][DepScan] Disable relocation checks (#225563)
This internally broke an incremental build. Disable while it gets
investigated.

tests: log in as admin, because root is disabled now
Both boot tests sent "root" with an empty password. nextbsd-overlays
f9dcd5b (#278) disabled root the way Darwin does -- its password field went
from empty to "*" -- so login rejects every password including the empty
one, and both stages failed with "Login incorrect".
Nothing was wrong with the image. The tests described an image that no
longer exists, and this branch is simply the first build since: overlays
landed that change on 2026-09-23 20:23 and this repo last built green on
2026-09-22 20:45.
That also explains the second failure. ROOT-NOATIME greps the transcript
for "on / (ufs, local, noatime", which `mount` prints -- and mount never
ran, because there was no shell. One cause, two red lines.
admin is the way in. nss_directory_services gives an account carrying
noPassword an EMPTY passwd field for a privileged caller
(dsdb_pack_passwd), and login is privileged, so an empty password is

[mlir][bufferization] Support matching permutation maps in Linalg analysis (#226079)
Generalize `LinalgOpInterface::bufferizesToElementwiseAccess` to
recognize participating tensor operands with identical permutation
indexing maps, instead of requiring identity maps.
This enables in-place bufferization after loop interchange. Projected
and mismatching maps, reduction iterators, and sparse operands remain
conservatively rejected.
The tests cover the analysis decision as well as end-to-end
bufferization without an allocation or copy.
[mlir][bufferization] Handle disjoint subsets in One-Shot Analysis (#224184)
Teach One-Shot Analysis to ignore RaW conflicts between provably
disjoint subset reads and writes. Trace aliasing reads back to subset
extraction ops to handle alias-only operations such as
tensor.extract_slice.
Add tensor and vector tests for disjoint, overlapping, and unknown
subsets.
rpi: boot normally, not verbose
The Pi boot partition shipped `FreeBSD: -v` in cmdline.txt, from when the
board was being brought up and its serial log was the only instrument
there was. That is no longer the right default, and leaving it was a trap
rather than a nicety.
The Pi rootfs carries nextbsd-overlays' loader.conf.d, so it already gets
boot_mutemsgs="YES" (#363). RB_VERBOSE is exactly what that mute exempts,
so a -v that arrived would turn the quiet console back off on this board
alone, while every other machine stayed quiet.
It does not arrive today: parse_fdt_bootargs() only parses when
fdt_get_chosen_bootargs() succeeds, and a tryboot with that line produced
a boot that was not verbose, so the firmware appears not to be writing
/chosen/bootargs at all (nextbsd-kernel#93). So the flag was inert -- and
would have started working silently, on every Pi image, the day that was
fixed. A latent regression rather than a current one.

[RISCV] Make the getJumpTableIndex search more structured. NFC (#226266)
Instead of recursively searching through instructions with certain
opcodes, look for the specific patterns we use for jump tables.
I've added a few TODOs for Zilx and SHXADD_UW.

Pull firewire fix from Takashi Sakamoto:
"Fix a race in the cdev layer that can cause a fw_iso_resource_auto
object to transition back to a previous state. This can happen when a
file descriptor is closed while the work item for the object is
running. The race can leak several memory objects, including client
object itself"

[RISCV][llvm-readobj] Treat RISC-V float ABI e_flags field as an enum (#226313)
EF_RISCV_FLOAT_ABI is a 2-bit field, not independent flag bits, so
printFlags needs to be told about the mask. Previously a quad-float ABI
object printed "single-float ABI, double-float ABI, quad-float ABI"
instead of just "quad-float ABI".

[mlir][tosa] Use optnone for compliance initialization under HWAsan (#226310)
Similar to #223586, compiling the file is very slow when we enable
HWAsan internally. Mark the constructor with optnone under
LLVM_HWADDRESS_SANITIZER_BUILD to skip expensive optimization and
register allocation passes, bringing compilation time from 10+m to ~30s.
