[AArch64] Fix DUP-of-extload combine to ignore chain uses (#201351)
The original combine bailed when the load had more than one use, but
counted chain uses too.
[orc-rt] Make NativeDylibManager::lookup return optional addresses. (#201519)
NativeDylibManager::lookup used to return (asynchronously) a vector of
void *s where null represented not-present. This commit updates it to
return a vector of std::optional<void *>s where std::nullopt represents
not-present and an address of zero indicates that the symbol is present
with an address of zero.
This matches the resolve semantics of SimpleExecutorDylibManager,
completing the alignment of the two implementations after the earlier
additions of the Mode argument to load() and the
required/weakly-referenced flag on lookup symbols.
[MLIR][XeGPU] Extend op definitions to support 3D+: dpas, dpas_mx (#199809)
**Summary**
Extend xegpu.dpas and xegpu.dpas_mx operations to support 3D and 4D
operands with batch dimensions, enabling batched matrix multiplication
workloads like [4, 128, 512] x [4, 512, 128] -> [4, 128, 128].
**Changes**
- Type definitions: Extended XeGPU_DpasOprType and XeGPU_DpasResType to
support rank 3-4 (previously 1-3 and 1-2)
- Op definitions: Extended dpas_mx scale operands to support rank 3-4
vectors
- Verifiers: Updated verifyDpasDimensions() to validate batch dimensions
across A, B, and result operands; updated DpasMxOp::verify() for
batch-aware scale dimension checks
- Documentation: Added comprehensive documentation explaining batch
dimensions, microarchitecture-specific matrix sizes, and 3D/4D usage

smtpd was already fork+exec privsep, and starts 6 copies which are
the same binary.
I first decided to random-relink smtpd because of some recent close
calls (in the IPC codepaths, which could have played part in lateral
movement following a primary hole). Then it dawned on me that I can
random relink each of the privsep binaries to be unique, in the same
style as sshd.
Each binary now contains a lot of code it does not need (and is not
reached, but the code remains). That can be refactored as a later
step.
The new /etc/rc relink code will automaticall pick these up.
vague approval martijn, gilles, millert
httpd worries me a bit, so I want to random-relink it at boot.
The new /etc/rc relinking components will automatically pick up this
new directory and process it.
[MLIR][XeGPU] Extend op definitions to support 3D+: load_nd, store_nd, prefetch_nd (#199811)
**Summary**
Extend xegpu.load_nd, xegpu.store_nd, and xegpu.prefetch_nd operations
to support 3D and higher-dimensional tensor descriptors with batch
dimensions, enabling batched memory operations for workloads like [4, 8,
16] tensor loads/stores.
**Changes**
- Verifiers: Removed rank > 2 checks in LoadNdOp::verify() and
StoreNdOp::verify() to allow 3D+ tensor descriptors
- Documentation: Added comprehensive documentation explaining: Tensor
descriptors can be 1D, 2D, 3D, or higher dimensional; Batch dimensions
(leading dimensions) are unrolled to unit dimensions during lowering;
Operations execute at 2D granularity at subgroup level to match 2D block
IO hardware; Examples of 3D operations
- Tests: Added unit tests for 3D operations (load_nd_3d, store_nd_3d,
prefetch_nd_3d)

pci: bcm2838: cleanup on attach failure to fix devmatch panic
Specifically on the RPi CM4, we currently don't set the controller up
right and it never moves into the ready state (we don't observe the link
active bit). Failure to cleanup here actually results in a panic not
long after, due to a use-after-free in the rman bits. Further down in
pci_host_generic, we have some rman stashed in the softc that are
initialized and placed onto the rman tailq, then the softc is later
freed without an rman_fini() to pull them off of the tailq properly.
Note that PCIe on this board won't come up at boot without something
plugged in, so it currently can't be booted with an empty slot with the
intent to hotplug a supported card. Some issues with controller startup
have been observed with Broadcom NICs in the wild, but no problems have
been observed with other NICs and a variety of different PCIe cards.
Shout-out to Vince <git at darkain.com> for the extensive debugging and
analysis to arrive at this conclusion.

pci: pci_host_generic: provide cleanup methods outside of detach
If device_attach() fails, we're expected to actually cleanup after
ourselves because device_detach() will not be called. Factor out the
cleanup bits that don't rely on attach having actually succeeded so
that we can cleanup properly in bcm2838_pci.

[LoopInterchange] Check all inner-exit LCSSA PHIs (#200860)
areInnerLoopExitPHIsSupported() returned true as soon as it saw the
reduction LCSSA PHI, skipping the user-check for any later LCSSA PHIs.
If one had a non-PHI user, legality wrongly succeeded and the transform
hit a cast<PHINode> assertion. Use continue so the remaining PHIs are
still validated.
Fixes #200811.

[CodeGen][AMDGPU] Remove premature empty subrange elimination (#201263)
This commit removes a call to `removeEmptySubRanges` inside
`SplitEditor::rewriteAssigned` which removes empty subranges that may be
expected at a later stage. The empty subranges are eliminated by a later
call to `removeEmptySubRanges`.
Fixes https://github.com/llvm/llvm-project/issues/199337.

[ORC] Replace ExecutorSymbolDef with ExecutorAddr in remote lookup. (#201492)
Update DylibManager and associated interfaces to return ExecutorAddrs
for remote symbols, rather than ExecutorSymbolDefs. No clients were
using the flags component of ExecutorSymbolDef, and this brings the
SimpleExecutorDylibManager implementation in OrcTargetProcess into
closer alignment with the NativeDylibManager implementation in the new
ORC runtime.
