[OpenCL] Diagnose error for zero-length array (#193163)
OpenCL C is based on C99 and C11, which don't support zero-length array.
Update clang/docs/ReleaseNotes.rst for potential breaking change.
[Clang][CodeGen] Fix sret lifetime marker AS mismatch after #186275 (#193850)
After #186275, the sret address space can differ from the alloca address
space (e.g., AS 0 vs AS 5 on AMDGPU). In CGCall.cpp EmitCall(), when a
discarded-value sret temporary is created, SRetPtr is allocated in the
alloca AS and a lifetime.start is emitted. The pointer is then
addrspacecast'd to match the sret AS, but the CallLifetimeEnd cleanup
was using the addrspacecast'd pointer, triggering an assertion in
EmitLifetimeEnd ("Pointer should be in alloca address space").
Saves the original alloca pointer before the addrspacecast and uses it
for the lifetime-end cleanup.

[libclc] Allow testing unresolved symbols on multiple libraries (#193647)
Our downstream generates multiple libraries for a single target. This
change allows testing multiple libraries.
[libclc][CMake] Remove CMAKE_C_COMPILER_ID check (#186717)
When LLVM_TARGETS_TO_BUILD does not contain the host target, runtime
build can not identify a compatible target triple for the host compiler.
CMAKE_C_COMPILER is set to clang, and CMAKE_C_COMPILER_ID is empty
although the compiler is functional.
Remove CMAKE_C_COMPILER_ID check. CMakeTestCLCCompiler.cmake already
provides a real functional guard.
This change ensures valid configurations can proceed, e.g.:
LLVM_TARGETS_TO_BUILD=AMDGPU;
RUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc;
LLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm".
Note CMAKE_C_COMPILER_WORKS is always true after `project(Runtimes C CXX
ASM)` in runtimes/CMakeLists.txt.
[LazyValueInfo] Support vector types in ICmp condition handling (#192900)
Use m_APInt matcher instead of ConstantInt dyn_cast so splat vector
constants are handled, and relax the integer type check to accept
integer vector types.
Fixes https://github.com/llvm/llvm-project/issues/192094
[NFC][Clang][Sema] Apply rule of three to Sema helper classes (#193835)
Static analysis flagged these classes. They declared a destructor but
not copy constructor or copy assignment. Since these classes don't need
them, this change declares them deleted.

[clang] NFC: Add test case for #178324 and mark it as fixed (#190490)
Issue #178324 was actually fixed by #187755
We lost the "declaration does not declare anything" warning since the
regression was introduced, but that was because:
1) Since #78436 we treat __builtin_FUNCSIG in a dependent context
effectivelly as if it contained a template parameter.
2) Our decltype implementation treats eexpressions containing template
parameters as if they were completely opaque (but alas this goes against
the spec, which says in [temp.type]p4 this should be looking only at
type dependence).
3) Since the decltype is opaque, we don't know what lookup will find, so
we can't issue the warning because we don't know if we are going to end
up with a type or an expression.

Pull networking fixes from Jakub Kicinski:
"Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
weeks before the merge window. Lots of AI-aided bug discovery. A newer
big source is Sashiko/Gemini (Roman Gushchin's system), which points
out issues in existing code during patch review (maybe 25% of fixes
here likely originating from Sashiko). Nice thing is these are often
fixed by the respective maintainers, not drive-bys.
Current release - new code bugs:
- kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
Previous releases - regressions:
- add async ndo_set_rx_mode and switch drivers which we promised to

[CIR] Add coroutine cleanup handling and update co_return semantics (#189281)
This PR adds cleanup handling for coroutine frame destruction. The
cleanup is emitted as a conditional that checks the result of the
`coro.free` builtin, which is used to determine whether the coroutine
frame was heap-allocated, if the returned pointer is null, no
destruction is performed. Additionally, this PR changes how co_return is
represented: previously, it was lowered directly into a branch to the
block containing the final suspend logic, but now a new `cir.coro.body`
operation is introduced to represent the user-written coroutine body.
Inside this region, `cir.co_return` operations mark exits from the
coroutine body and represent structured control flow that transfers
execution to the final suspend point. The lowering of this structured
control flow into explicit branches is deferred to a future PR in the
FlattenCFG pass.
