[mlir] Fix assertion crash in test-symbol-uses with nested modules (#185069)
The `SymbolUsesPass` walked all nested `SymbolOpInterface` ops in a
module, including those belonging to nested symbol tables (e.g., nested
modules). When an external `func.func` inside a nested module had no
uses in the outer module's body region, it was incorrectly added to
`deadFunctions` for erasure. Since the outer module's `SymbolTable` does
not contain the inner module's symbols, the subsequent
`table.lookup(name)` assertion would fail with:
Assertion `table.lookup(name) && "expected no unknown operations"`
failed.
Fix by only tracking functions that are direct children of the enclosing
module, skipping functions owned by nested symbol tables.
Fixes #60583

[Clang][ExprConst] Handle APValue::LValue in BitCast (#184865)
Instead of marking the branch unreachable, emit an unsupported type
diagnostic and return false when encountering `APValue::LValue` in
`APValueToBufferConverter`.
A good example of this is:
```
long fn() {
return __builtin_bit_cast(long, (long)&fn);
}
```
Although `&fn` itself is a pointer type, the cast `(long)` converts it
to an integer type, which passes `checkBitCastConstexprEligibilityType`.
Thus, eventually, we see it in Converter, which does not expect an
LValue.

[LLDB] Allow one-line summaries in the presence of synthetic child providers (#184926)
This is driven by the Swift language. In Swift many data types such as
Int, and String are structs, and LLDB provides summary formatters and
synthetic child providers for them. For String, for example, a summary
formatter pulls out the string data from the implementation, while a
synthetic child provider hides the implementation details from users, so
strings don't expand their children.

[clang] Fix filler handling for new expression with unspecified bound. (#182203)
Array new with a runtime bound requires an "array filler" to initialize
elements which aren't explicitly initialized. Array new with an
unspecified bound doesn't need this; the array length is a compile-time
constant. Make sure SemaInit doesn't confuse the two cases.
Fixes #81157.

This will allow us to unit-test it in a follow-up patch. We could test
`LocateExecutableScriptingResources` directly, but that requires a valid
`Module`/`ObjectFile`/`SymbolFile`. That's a lot of boilerplate/set to
ultimately just test the `dSYM` logic. The helper just takes
`FileSpec`s, which are much easier to construct in a test.

[CIR] Fix array constant initialization with trailing zeros (#184933)
If an array is explicitly initialized with more than eight non-zero
values followed by a number of explicit zero initializers, CIR generates
a constant record initializer with a constant array that is declared as
the size of the non-zero initializers but with the explicit zero
initializers included in the array initialization attribute. This
resulted in an error when we tried to lower that attribute to LLVM IR.
This patch fixes that problem and adds a verifier to ConstantArrayAttr
to check for that condition.

[Clang] Fix invalid sret addrspacecast for placement new on HIP (#183639)
When a HIP kernel uses placement new with a function returning an
aggregate via sret (e.g. `new (out) T(make_t())`), and the placement
destination is in global memory (addrspace 1), the sret pointer was
addrspacecast'd to addrspace 5 (private), producing an invalid pointer
that faults at runtime.
Instead of casting the caller's pointer directly, materialise a
temporary alloca in the callee's expected address space, pass that as
the sret argument, and copy the result back to the original destination
after the call.

[clang][diagnostics] Stable IDs for Clang diagnostics (#168153)
Part of the implementation of [[RFC] Emitting Auditable SARIF Logs from
Clang](https://discourse.llvm.org/t/rfc-emitting-auditable-sarif-logs-from-clang/88624)
SARIF diagnostics require that each rule have a stable `id` property to
identify that rule across runs, even when the compiler or analysis tool
has changed. We were previously setting the `id` property to the numeric
value of the enum value for that diagnostic within the Clang
implementation; this value changes whenever an unrelated diagnostic is
inserted or removed earlier in the list.
This change sets the `id` property to the _text_ of that same enum
value. This value would only change if someone renames the enum value
for that diagnostic, which should happen much less frequently than
renumbering.
For now, we will just assume that renaming happens infrequently enough
that existing consumers of SARIF will not notice. In the future, we
could take advantage of SARIF's support for `deprecatedIds`, which let a
rule specify the IDs by which it was previously known. This would let us
rename, split, or combine diagnostics while still being able to
correlate the new diagnostic IDs with older SARIF logs and/or
suppressions.
Nothing in this change affects how warnings are configured on the
command line or in `#pragma clang diagnostic`. Those still use warning
groups, not the stable IDs.
### Potential discussion topics
>From @AaronBallman on the RFC:
>We believe some open questions remain (things like whether a unique ID
is on the per-diagnostic level or on the diagnostic group level, whether
the ID is explicitly spelled in the .td file or implicitly generated,
whether we document the IDs, etc), but we think those questions are best
decided in PR discussions with interested parties rather than an RFC.
As a starting point, this PR proposes the following answers to those
open questions:
- _whether a unique ID is on the per-diagnostic level or on the
diagnostic group level_ - per-diagnostic level. For my justification,
see [this portion of the RFC
discussion](https://discourse.llvm.org/t/rfc-emitting-auditable-sarif-logs-from-clang/88624/11?u=dbartol.).
- _whether the ID is explicitly spelled in the .td file or implicitly
generated_ - Implicitly generated, but I'd be happy to have a way to
explicitly specify it. I just think that the in-code identifier is a
reasonable default, and manually reviewing the IDs of thousands of
existing diagnostics would add little benefit.
- _whether we document the IDs_ - For now, the IDs are only exposed to
the user (and other tools) in the SARIF file, so I don't think we need
to document these. We could certainly add this information to the output
of `diagtool` in the future if users find it relevant.

[clang][CodeGen] Fix size calculation in vbptr split memory region in EmitNullBaseClassInitialization (#184558)
When splitting memory stores around multiple virtual base pointers
(vbptrs)
in the Microsoft ABI, the calculation for the size of the memory region
after
each vbptr was incorrect.
The bug/old calculation: SplitAfterSize = LastStoreSize -
SplitAfterOffset
This subtracts an absolute offset from a relative size, causing
incorrect (too small) sizes after the second vbptr.
The correct size should be:
SplitAfterSize = (LastStoreOffset + LastStoreSize) - SplitAfterOffset
Since all store regions extend to the end of the non-virtual portion
(NVSize),
this patch uses the simplified form:
SplitAfterSize = NVSize - SplitAfterOffset
The bug causes the assertion failure: "negative store size!"

when landing the Mustache MD patch since this benchmark isn't tested.
Also added missing libraries in CMake that prevented me from building
the benchmark locally.

[CIR] Add MLIR ABI Lowering design document
Design document for MLIR dialect-agnostic calling convention
lowering that builds on the LLVM ABI Lowering Library
(llvm/lib/ABI/) as the single source of truth for ABI
classification. Dialects use the library via an adapter layer:
ABITypeMapper maps dialect types to abi::Type*, the library
classifies arguments and returns, and a dialect-specific
ABIRewriteContext applies the decisions back to IR operations.
Targets x86_64 and AArch64, with parity against Classic Clang
CodeGen validated through differential testing.

[CIR] Fix a crash when source location is unknown (#185059)
When we call `getLoc()` with an invalid `SourceLocation` and
`currSrcLoc` is also invalid, we were crashing or asserting. I tracked
down one case where this was happening (generating an argument in a
vtable thunk) and fixed that to provide a location. I also am updating
the `getLoc()` implementation so that it will use an unknown location in
release builds rather than crashing because the location isn't critical
for correct compilation.

[flang,acc] Support -ffp-maxmin-behavior option in lowering. (#184730)
This patch adds `flang -fc1` option `-ffp-maxmin-behavior` and
propagates it throughout Flang, so that semantics context,
lowering and the pass pipeline builder can use it.
MAX/MIN intrinsic and OpenACC max/min reduction lowering
are now controlled by the option.
I kept the `Legacy` mode, which is the default and matches the current
behavior. I am going to test and merge a follow-up patch that
replaces `Legacy` with `Portable`.

EmitAggregateCopy, which asserts that the type has a trivial copy/move

[MC][WebAssembly] Allow strings for import modules and names in asm (#182896)
Current tooling for the WebAssembly component model uses import modules
and names such as `$root` and `[thread-index]`. Importing these from
assembly files requires support for non-valid identifiers in
`.import_name` and `.import_module` directives. This PR adds support for
specifying those as strings, e.g.:
```asm
.import_module __wasm_component_model_builtin_thread_index, "$root"
.import_name __wasm_component_model_builtin_thread_index, "[thread-index]"

It was originally added in #67715 as a way to avoid the potentially

merge of #184441, the pass itself has been fixed to avoid this issue.
Given that, it is no longer necessary nor desirable to keep this switch.

[ASan][Windows] Fixing Windows shadow memory address for arm64 (#184902)
This is a prerequisite for full ARM64 Windows ASan support. The runtime
interception changes needed to make ASan functional end-to-end on ARM64
Windows will be opened separately.
Motivated by https://github.com/microsoft/STL/pull/6095 (more
specifically [this reference to
clang-cl](https://github.com/microsoft/STL/pull/6095#:~:text=Not%20enabling%20GH_002030_asan_annotate_string%20and%20GH_002030_asan_annotate_vector%20yet%20due%20to%20Clang%20issues.))
The latest MSVC toolset includes ARM64 AddressSanitizer support. This
change adds AArch64 to the Windows 64-bit shadow mapping condition when
compiling with `-fsanitize=address` with `clang-cl`. Without this,
consumers on Windows who target ARM64 with `clang-cl -fsanitize=address`
and then link with `link.exe` will see this at runtime:
```text
ERROR: AddressSanitizer: access-violation on unknown address
...
```
since the shadow memory offset is not properly assigned. Windows ARM64
uses the same dynamic shadow allocation strategy as x64 via
`__asan_shadow_memory_dynamic_address`.

[mlir][ODS] Fix notorious double-space bug in op printers (#184253)
When an op's assembly format prints an attribute via
`printStrippedAttrOrType`, two independent space-emission mechanisms
would fire: the op format generator emits a space before each argument,
and the attribute's generated `print` method also emits a leading space
(`shouldEmitSpace` initialized to true). This caused double spaces like
`gpu.shuffle xor`.
The usual workaround for this was to add double backticks to consume the
leading space.
Fixed by removing the leading space from generated attr/type `print()`
methods and compensating in the print dispatcher by conditionally adding
a space between the mnemonic and `print` call when the format starts
with a name or keyword rather than punctuation.
Also remove some workarounds for the double-spacing in op formats and
fix tests that now don't have leading spaces.

[HLSL][DirectX] Implement HLSL `mul` function and DXIL lowering of `llvm.matrix.multiply` (#184882)
Fixes #99138
- Defines a `__builtin_hlsl_mul` clang builtin in `Builtins.td`.
- Links the `__builtin_hlsl_mul` clang builtin with
`hlsl_alias_intrinsics.h` under the name `mul` for matrix cases
- Implement scalar and vector elementwise multiplication cases of the
`mul` function in `hlsl_intrinsics.h` and `hlsl_intrinsic_helpers.h`
- Adds sema for `__builtin_hlsl_mul` to `CheckBuiltinFunctionCall` in
`SemaHLSL.cpp`
- Adds codegen for `__builtin_hlsl_mul` to `EmitHLSLBuiltinExpr` in
`CGHLSLBuiltins.cpp`
- Vector-vector cases lower to `dot` (except double vectors, which
expands to scalar multiply-adds).
- Matrix-matrix, matrix-vector, and vector-matrix multiplication lower
to the `llvm.matrix.multiply` intrinsic
- Adds codegen tests to `clang/test/CodeGenHLSL/builtins/mul.hlsl`
- Adds sema tests to `clang/test/SemaHLSL/BuiltIns/mul-errors.hlsl`
- Implements lowering of the `llvm.matrix.multiply` intrinsic to DXIL in
`DXILIntrinsicExpansion.cpp`
Note: Currently the SPIRV backend does not support row-major matrix
memory layouts when lowering matrix multiply, and just assumes
column-major layout. Therefore this PR also makes the DirectX backend
only assume column-major layout. Implementing support for row-major
order shall be done in a separate PR. (Tracked by
https://github.com/llvm/llvm-project/issues/184906)

[AMDGPU][SIInsertWaitcnts][NFC] Simplify logic in GFX12Plus::applyPreexistingWaitcnts (#184925)
The loop is collecting the first instruction of each waitcnt kind and is
erasing the rest, with the exception of DEPCTR which needs more checks.
The existing code was factoring out the instruction deletion and the
setting of the collected instruction variables. But the special handling
for DEPCTR and the in-loop deletion of `S_WAITCNT_lds_direct` was just
complicating the logic.

[HLSL][Matrix] Make matrix truncation respect default matrix memory layout (#184280)
Fixes #183127 and #184371
This PR makes the matrix truncation cast implementation use the new
matrix flattened index helper functions introduced by #182904 so that it
reads elements from the source matrix using the default matrix memory
layout instead of always assuming column-major order.
This PR also fixes a bug where matrix truncation truncated the wrong
elements.
