[mlir][ABI] Add the nofreeobj param attr to the LLVM dialect (#222137)
Since #218404 clang marks every indirect argument nofreeobj rather than
nofree. LLVM allows it on returns too.

[libc++] Opt `std::*set` out of map key extraction optimization (#220452)
PR #154512 (relanded by #155565) removed `__can_extract_map_key`, which
had a blanket opt-out for `std::*set`s. The new logic does not have that
opt-out, leading to `std::set`s being incorrectly constructed.
The new regression tests demonstrate this, but essentially the idea is:
1. Have `std::set<T> foo;`
2. Call `foo.emplace(some_t,
arg_that_influences_comparisons_or_hashes);`
3. The emplace will internally search using `some_t` as the key, *not*
`T(some_t, arg_that_influences_comparisons_or_hashes);`
This opts out `std::*set` from this optimization to match previous
behavior.
Tests and fix were produced by an LLM. I reviewed them and they seem
reasonable to me, though I don't have a strong background in libc++
testing conventions.

[MLIR][CMake] Remove aggregate generated-header ordering

[MLIR][CMake] Add HEADER_LIBS and document CMake infrastructure
Add HEADER_LIBS as a flat list of literal library targets for generated headers
included without a link relationship. Resolve aliases and forward references,
accept imported libraries as already generated, follow nested HEADER_LIBS and
link interfaces, and reject missing, executable, utility, or generator-
expression entries with configure-time diagnostics. Represent header-only
edges in the common internal INTERFACE graph, including cyclic relationships.
Record links added by mlir_target_link_libraries for the same deferred ordering.
Add explicit, commented HEADER_LIBS edges for every audited header-only include
that is not covered by mlir-generic-headers, and keep this facility a rare
layering escape hatch.
Document dialects, interfaces, passes, PDLL, generated documentation, library
visibility, C API aggregation, tools, exports, standalone consumers, and the
generated-file model. Add a CMake fixture covering cycles, aliases, conditions,
LINK_ONLY, imported and ignored items, post-hoc links, and invalid providers.
Build each consumer independently from a clean state to verify transitive

[CMake] Propagate generated-header prerequisites through link dependencies
The goal is to simplify and make more robust the handling of generated-header
(TableGen) dependencies. Today these dependencies are managed manually, which
is fragile: missing edges often surface only in parallel builds, and sometimes
in incremental builds.
Record each llvm_add_library DEPENDS list independently from the cumulative
LLVM_COMMON_DEPENDS value, and mark public TableGen targets as generated-header
prerequisites. A deferred traversal follows every direct non-INTERFACE link and
transitive link interface, resolves aliases, and conservatively extracts target
candidates from generator expressions.
Represent generated-header prerequisites with internal INTERFACE libraries.
Let CMake propagate their utility dependencies through the header graph, and
reuse each provider's interface to handle cycles without computing closures.
Disabled generator-expression arms may generate extra headers, but cannot
introduce a provider library or object cycle.

[AMDGPU] Drop the redundant operand register-class verifier check
The generic MachineVerifier already rejects a register operand whose
class does not fit the instruction's operand class, for both virtual
(hasSuperClassEq / getMatchingSuperRegClass) and physical (contains)
registers, using the HwMode-resolved operand class. On subtargets that
require aligned VGPRs that class is the even-aligned one, so the generic
check catches a misaligned tuple on its own.
Remove SIInstrInfo::verifyInstruction's own alignment and physical
register-class checks and the now-unused getUnalignedEquivalentRC helper.
Misaligned tuples now report the generic "Illegal virtual/physical
register for instruction" instead of "Subtarget requires even aligned
vector registers"; a bad physical class reports the same instead of
"Operand has incorrect register class".
[MLIR] Fix and classify generated-header dependencies
List the TableGen targets owned by each affected library, and add the missing
LLVM generated-header, SPIR-V source-generation, OpenACC/OpenMP generated-input,
and CIR operation/type prerequisites found by clean dependency audits. Correct
two stale copy-paste dependencies and the duplicate CIR link entry.
The Transforms pass declarations and dialect inliner interface are independent
of any dialect. Classify both under mlir-generic-headers, and associate the
inliner interface with MLIRTransformUtils, which publishes InliningUtils.h.
This gives every MLIR library the required ordering without repeated
header-only edges.

[libc++] Backport resolution of LWG2187 to C++11 (#222006)
libc++ has LWG2187 implemented in
2d6e2834a8abcce862ef17c44f62e4de41662748 but only since C++14 mode.
Usually, resolution of an LWG issue should be treated as a Defect Report
and applied to old modes. In the case of LWG2187, the resolution should
be applied to C++11.

[orc-rt] Add Mangling.h with platform symbol name mangling (#222315)
This implements a cut-down version of the LLVM equivalent (in
llvm/include/llvm/ExecutionEngine/Orc/Shared/Mangler.h): SymbolNameSpec
pairs a name with a kind (assembly, C). Mangling functions
(withMangledNameDo, mangledCopy) apply mangling to SymbolNameSpecs based
on the symbol name kind.
These utilities will be used to report symbols (e.g. controller
interface symbols) in the platform's native mangling, so that linking
against them requires no special handling.

[MLIR][Remark] Import LLVM optimization remarks into the remark engine (#222300)
Collect LLVM side of remarks with MLIR's remark infra.
LLVM passes emit their own [optimization
remarks](https://llvm.org/docs/Remarks.html) and MLIR has own. This PR
bridges MLIR and LLVM remarks.
`ModuleToObject` installs a `remark::LLVMToMLIRDiagnosticHandler` on the
`llvm::LLVMContext` it compiles with, which imports these remarks into
the remark engine: the category is the LLVM pass name prefixed with
`llvm-`, the LLVM remark name becomes the name, the message is stored
under the `Remark` argument and the structured LLVM arguments are copied
as metrics. The remark filters therefore select LLVM remarks by pass
name, and `llvm-.*` selects all of them.

prerequisites. A deferred traversal follows every direct non-INTERFACE link and
transitive link interface, resolves aliases, and conservatively extracts target

Add only the resulting generated-header utility targets as compilation-order
prerequisites. Avoiding dependencies on provider libraries keeps mutually
linked static libraries acyclic and works across generators without waiting for
provider archives. Disabled generator-expression arms may generate extra
headers, but cannot introduce a library or object cycle.
Do not link provider libraries directly to object libraries. That approach was
reverted after an ODR regression when LLVM_LINK_LLVM_DYLIB was enabled. Cache
provider closures so repeated link relationships do not repeat the traversal.
