[CIR] Support zero-result ops in clangir TableGen lowering (#202273)
### summary
This is follow-up to https://github.com/llvm/llvm-project/pull/199599
A CIR op can set the llvmOp field to have cir-tblgen auto-generate its
CIR→LLVM lowering instead of using a hand-written pattern.However, the
generated body forwards the result type via op.getType(), which only
compiles for single-result ops. As a result, ops with zero results could
not use this feature.
To fix this, teach CIRLoweringEmitter to emit an empty mlir::TypeRange{}
for zero-result ops. Then switch cir.lifetime.start and cir.lifetime.end
to use llvmOp (dropping their hand-written lowering). The lifetime.cir
test covers the generated path.
[SCEV] Speed up forgetLoop by avoiding def-use walk for loop-header PHIs (#201572)
Every cached SCEV varies with Loop `L` transitively contains an
`AddRec`, and every `AddRec` for the loop is recorded in `LoopUsers[L]`.
`forgetMemoizedResults` already closes this set transitively through
`SCEVUsers` and `ExprValueMap`.
Therefore `forgetLoop` does not need to walk the def-use chain starting
from header PHIs, it only needs to initialize `ToForget` with
`LoopUsers[L]` and explicitly remove each header PHI's entries from
`ValueExprMap` and `ConstantEvolutionLoopExitValue`, push its cached
SCEVs into `ToForget`.
As a side effect, cached SCEVs that reside in the loop body but do not
depend on any `AddRec` for the loop (e.g. a `SCEVUnknown` for an icmp)
are no longer invalidated.
chat/py-xmpppy: Update to 0.7.4
2026-06-09 0.7.4
================
- Fixed ``UnicodeDecodeError`` while logging large stanzas by using ``backslashreplace`` handler.
Thanks, @vthriller and @normanr.
- Improved compatibility with Python 2. Thanks, @vbontchev.
[NFC][clang-sycl-linker] Standardize error messages to LLVM coding style (#202767)
Follow LLVM coding standards for error messages: use lowercase first
letter and no trailing period. This matches the style used throughout
LLVM tools (llvm-objcopy, lld, etc.) and aligns with the official
guidance in llvm/docs/CodingStandards.rst.
Updated corresponding test assertions in basic.ll and triple.ll.
[SSAF] Let function parameters inherit linkage from their parent functions (#201946)
SSAF treats parameters as entities and may not always associate them
back to their parent functions. Therefore, it needs to identify
parameters of functions with external linkage across different TUs.
Treating them as having no linkage (as in C++) causes the same parameter
in different TUs to be assigned different EntityIDs. As a result, the
behavior of the parameter across multiple TUs cannot be correlated.

[RISCV] Adopt SpacemitX60's scheduling model for `-mtune=generic` (#167008)
Per our discussions in RISC-V roundtable during LLVM Dev Meeting 2025,
there has been a consensus to create a base / generic scheduling model
for the most common performance tuning usages. As the first step, we
agree to use SpacemitX60's scheduling model for that purpose for the
time being, with an expectation to create a standalone generic model
that could evolve independently in the future.
This patch sets `-mtune=generic` to use SpacemitX60's scheduling model,
and documents the rationale behind it, including the roadmap ahead as we
discussed.

Reset the task before dropping the slot instead of after, which was
causing out-of-bound memory accesses.
- Fix HA monitor synchronization and cleanup
Ensure synchronous cleanup for HA monitors by running timer callbacks
in RCU read-side critical sections and using synchronize_rcu() during
destruction.
- Avoid armed timers after tasks exit
Add automatic cleanup for per-task HA monitors to prevent timers from
firing after task exit.

[lld][MachO] Handle compact unwind entries with no matching symbol (#180009)
Context: This change is to support [MachO basic block hot-cold
splitting](https://discourse.llvm.org/t/rfc-support-fsplit-machine-functions-on-macho-arm64/89739)
- though it's presented below outside of this context.
Compact unwind entries can reference function addresses that have no
corresponding symbol in the object's symbol table (e.g. functions with
temporary local labels). Previously, this would trigger an assertion
failure in assert-enabled builds, or silently drop the unwind entry in
release builds, resulting in missing unwind info at runtime.
Fix this by synthesizing a local `Defined` symbol when no symbol exists
at the target address of a compact unwind entry, so that unwind info is
correctly emitted.
