[SelectionDAG] Don't over-claim alignment on vector splice/compress stack MMOs (#200622)
expandVectorSplice and expandVECTOR_COMPRESS allocate their scratch slot
on the stack with getReducedAlign, but the memory accesses they generate
touching this slot use the type's natural alignment, which may be
larger!
[llvm-debuginfo-analyzer] Add support for LLVM IR format. (#200603)
llvm-debuginfo-analyzer is a command line tool that processes debug
info contained in a binary file and produces a debug information
format agnostic “Logical View”, which is a high-level semantic
representation of the debug info, independent of the low-level format.
Add support for the LLVM IR format and be able to generate logical
views. Both textual representation (.ll) and bitcode (.bc) formats
are supported.
This relands https://github.com/llvm/llvm-project/pull/135440, which was
reverted in https://github.com/llvm/llvm-project/pull/199890.
It includes the fixes for the buildbots problems.
[CIR][AMDGPU] Implement lowering for __builtin_amdgcn_dispatch_ptr (#199880)
Port `emitAMDGPUDispatchPtr` from OGCG. Emits the `amdgcn.dispatch.ptr`
intrinsic and inserts an address-space cast when the builtin's expected
return type differs.
[CIR] Fix cir.call_llvm_intrinsic lowering for 0-result ops (#199516)
`cir.call_llvm_intrinsic` declares `Optional<CIR_AnyType>:$result`, but
the lowering indexed `op->getResultTypes()[0]` unconditionally and OOBed
on void calls.
Guard with `getNumResults()` and pick the void overload of
`LLVM::CallIntrinsicOp::create` in `createCallLLVMIntrinsicOp`.
[clang][bytecode] Improve `getType()` (#200342)
We previously often fell back to the type of the declaration, which is
wrong if we're pointing e.g. to a nested array.
Add a new unit test to vaildate this.
Merge tag 'for-7.1/dm-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fix from Mikulas Patocka:

Add todo guard for declarative construct
Metadirective variants are lowered through genOMPDispatch, which
only handles executable constructs. If the generated construct
queue contains a declarative directive, route it to the existing
TODO path instead of dispatching it.
[ORC] Simplify DylibManager::lookupSymbols, remove LookupRequest. (#195954)
DylibManager::lookupSymbols used to take an array of LookupRequests,
where each request specified a handle and list of symbols to lookup
within that handle.
This commit replaces the array of lookup requests with a single handle
and list of symbols passed directly to lookupSymbols.
In practice all clients were passing a singlton array anyway, and
simplifying this signature significantly simplifies implementations.
Merge tag 'auxdisplay-v7.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-auxdisplay
Pull auxdisplay updates from Andy Shevchenko:
- Fix potential out-of-bound access in line-display library
- Miscellaneous refactoring and cleaning up
[ Andy says this could easily be delayed until 7.2, but it's _so_ tiny
that it's more work for me to schedule it for later than to just take
it now, and just doesn't seem worth delaying - Linus ]
* tag 'auxdisplay-v7.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-auxdisplay:

[SandboxVec][LoadStoreVec][AMDGPU] Remove early reject of mixed types (#200523)
Up until now mixing floats and non-floats was disabled in the legality
checks. This patch changes this. We are now eagerly vectorizing mixed
types, but we are also checking the cost model to make sure we don't
regress on targets where this is expensive.
[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
Fixes #8740
Fixes #61818
Fixes #190388
[clang-tidy] Add `bugprone-missing-end-comparison` check (#182543)
This PR introduces a new check `bugprone-missing-end-comparison`.
It detects instances where the result of a standard algorithm is used
directly in a boolean context without being compared against the
corresponding end iterator.
Currently the check can't handle algorithms returning `std::pair` and
`std::ranges::mismatch_result`, but it should be a good enough starting
point for future improvements.

documentation and some code refactor/cleanup)

[RISCV] Disable Zilsd CSR-pair generation when push/pop or save-restore is enabled (#200623)
We were generating duplicate/worse code due to the generation of the
`Zilsd` load/store doubles for handling `CSR's` when `Zcmp/Xqccmp` or
`Save/Restore Libcalls` were enabled.

[clang-tidy] Fix false positive in bugprone-use-after-move for std::tie (#192895)
std::tie(a, b) = expr reinitializes all variables passed to std::tie
because the tuple assignment operator writes back through the stored
references. The check was not recognizing this pattern, causing a false
positive on the second std::tie assignment in loops like:
std::tie(a, b) = foo(std::move(a), std::move(b));
std::tie(a, b) = foo(std::move(a), std::move(b)); // false positive
Add std::tie assignment as a reinitialization case in
makeReinitMatcher().
Fixes #136105.
