[flang] Added fir.create_box operation. (#210220)
This patch adds `fir.create_box` operation that allows
creating `!fir.box<>` values with arbitrary byte strides.
It can be used to recreate boxes describing non-contiguous
arrays from descriptor components (base_addr/lbs/extents/strides)
across offload regions.
This is just initial definition and code generation code.
The folders and passes producing this operation will be added
later.

waiting on CI to confirm bazel is correct as cannot build locally.
Can confirm this library will convert to BUCK internally at Meta and
build with buck2 where we do have in the default plugin list.

[lldb] Add SBProtocolServer to start protocol servers programmatically (#209923)
Starting a protocol server (such as MCP, and in the future potentially
DAP) is only possible from the command line today, via `protocol-server
start`. Add an SB API so an embedder can start one in its own process
and learn where to connect.
SBProtocolServer wraps ProtocolServer::GetOrCreate/Start/Stop and
exposes the listening connection URI. This lets a tool host the engine's
protocol server in-process and talk to it as a normal client, reusing
the server's tools rather than reimplementing them.

[NVPTX] Set default value of nvptx-allow-ftz-atomics to true (#206154)
This is a follow-up to https://github.com/llvm/llvm-project/pull/200732.
Setting the default value of nvptx-allow-ftz-atomics to true preserves
the status quo. It allows the NVPTX backend to emit native
floating-point atomic add instructions by default, rather than falling
back to the CAS loop required for strict FTZ compliance.
Correct FTZ handling forces a lot of existing code to emit CAS loops.
This introduces thread divergence, breaking code that relies on atomic
operations being non-divergent (for example, warp-wide atomic additions
followed by a load of the reduced value without explicit
synchronization).
While FTZ-correct atomic behavior is desirable as a long-term default,
introducing thread divergence into a common operation that previously
"happened to work" without synchronization is highly disruptive.
Defaulting to true makes the FTZ-correct behavior opt-in for now,
allowing users time to audit and adapt their code.
Test cases are updated to verify both enabled and disabled states of the
option, alongside the new default behavior.

[clang][analyzer] Fix assertion failure in StdLibraryFunctionsChecker with non-integral ssize_t (#209655)
In StdLibraryFunctionsCheckers' `RangeConstraint::checkSpecificValidity`
asserted that the constrained argument type is integral. When user code
typedefs `ssize_t` to a non-integral type (e.g. `float`) even though
this violates POSIX.1-2017, which requires `ssize_t` to be a signed
integer type, the signature still matches (same canonical type) and the
assertion fires during constraint validation. Remove it and let
`validateByConstraints` gracefully reject the summary by returning
false.

[SROA] Fix assertion failure when promoting self-referential load/store (#208826)
When LoadAndStorePromoter::run processes a block where a store's value
operand is defined by the load being promoted (a self-referential cycle
in unreachable code), it sets StoredValue to the load instruction. When
it then calls replaceAllUsesWith, the doRAUW assertion fires because the
replacement value contains the value being replaced.
The single-block promotion paths in promoteSingleBlockAlloca already
guard against this with a check for ReplVal == LI, replacing with poison
instead. This patch adds the same guard to the in-block load path in
LoadAndStorePromoter::run, which was missing it. Substituting poison is
correct here since this situation only arises in unreachable code.
The regression was introduced in #135609, which added the
propagateStoredValuesToLoads path in SROA that routes through
LoadAndStorePromoter::run. LoadStoreRewriter handles aggregates and is
unrelated to this path.
Fixes #204799

Tracking issue: #201242

[migration guide]:
https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines
This is a stacked PR based on #210208, which is the standalone rename
commit for this miscellaneous Markdown migration batch.
This was prepared with rst2myst plus LLM-assisted cleanup. LLDB man
pages are intentionally left as reStructuredText because LLDB man-page
building should not take on Markdown parser dependencies.
Unfortunately, many of these miscellaneous docs do not have working
standalone doc build targets, so I was not able to render HTML for all
of them. I think the scope is small enough that this is reviewable by
hand.

[HLSL] Enable frontend IR generation for SPIR-V in TypedBuffers-constructor.hlsl (#207421)
I found a stale `FIXME` marker while poking at SPIR-V resource lowering.
The test stated that SPIR-V codegen of
`llvm.spv.resource.handlefrombinding` and resource types was not
implemented. That codegen now exists in
`CommonSPIRTargetCodeGenInfo::getHLSLType`.
This change enables the test on SPIR-V and splits the tests to
distinguish DXIL and SPIRV expected IR patterns.

Gate this on a new global setting, diagnostics.collect-binaries, which

including them is opt-in.

[lldb] Truncate an over-wide symbol address in the IR interpreter (#210372)
IRInterpreter::ResolveConstantValue built a pointer-width APInt directly
from the address returned by FindSymbol. That address can be wider than
a target pointer, because lldb records extra information in the high
bits on some targets, such as the code/memory address-space tag on
WebAssembly.
A 32-bit pointer then cannot hold the tagged address and the APInt
constructor asserts, aborting the debugger when a function-valued
expression is evaluated (for example `expr main`).
Truncate to the pointer width instead of asserting, matching the idiom
already used in DWARFExpression. On targets whose addresses fit in a
pointer this is a no-op.

[CIR] Terminate conditional regions after creation; fix glvalue conditional with a throw arm (#210384)
Follow-up to #208850: @andykaylor's comments about
`CIRGenFunction::emitConditionalBlocks` also have a similar
insertion-point problem.
The PR addresses the two related problems found while looking into the
conditional branch emission path:
**1. Terminate conditional regions after creation instead of patching
yields**
`CIRGenFunction::emitConditionalBlocks` still had the save-and-patch
insertion-point machinery removed from the scalar path in #208850. The
path is unreachable, and its guard is saved only after
`cir.unreachable`, where a patched yield would generate the dead code.
The machinery is removed; regions are closed with
`terminateStructuredRegionBody` after creation.
The aggregate emitter had the reverse problem: an unconditional
cir.yield after each arm lands in the dead block a throw leaves behind
and keeps it in the final CIR:
```
struct test_s { int x; int y; };
void test_throw(bool flag) {
test_s a = flag ? throw 0 : test_s{1, 2};
}
mlir
cir.if %2 {
...
cir.throw %3 : !cir.ptr<!s32i>, @_ZTIi
cir.unreachable
^bb1: // no predecessors <-- dead block kept alive by the yield
cir.yield
} else {
...
}
```
The explicit yields are removed; `emitIfOnBoolExpr` already terminates
each region, adding a yield only where one is missing. Tests pin the
dead block's absence with CIR-NEXT after `cir.unreachable`.
**2. Fix glvalue conditionals with a throw arm using a region-local
pointer**
```
int &ref_cond(bool c, int &x) { return c ? x : throw 0; }
// error: operand #0 does not dominate this use
// fatal error: CIR module verification error
```
With one arm throwing, `emitConditionalOperatorLValue` returned the
surviving arm's LValue directly, valid in OG CodeGen's flat CFG, invalid
in CIR where the pointer is materialized inside the ternary's region:
```
%4 = cir.ternary(%3, true {
%8 = cir.load %1 ... // pointer loaded inside the region
cir.yield %8 : !cir.ptr<!s32i>
}, false { ... cir.unreachable })
cir.store %8, %2 ... // region-local %8 used outside the region
```
Existing tests missed it because a local's pointer is a function-entry
`alloca`, so dominance held by accident. The fix addresses the result
through the ternary's result value, which the yield carries out. New
tests cover a reference parameter, assignment via the conditional, and
member access, all of which previously failed verification.

[llvm-libtool-darwin] Ensure filelist buffer is null-terminated (#205115)
[llvm-libtool-darwin] Ensure filelist buffer is null-terminated
In llvm-libtool-darwin.cpp, `MemoryBuffer::getFileOrSTDIN` was
previously called to load the filelist with `RequiresNullTerminator` set
to `false`. However, the retrieved buffer is subsequently passed to
`llvm::line_iterator`.
Since `llvm::line_iterator` explicitly requires its underlying buffer to
be null-terminated, omitting this requirement can result in an
out-of-bounds read/buffer overrun when parsing the file list.
This change fixes the issue by requesting a null-terminated buffer
(`RequiresNullTerminator=true`).

[LLDB] Enable SBTypeSynthetic manipulation for SBValue instances (#209056)
Allow manipulating the scripted synthetic children frontend selection
process for individual `SBValue` instances.
The motivating use-case is supporting custom data structures, type
erasure systems, and facilitating debugging handle based C APIs. Below
is an example of such a use-case of an anonymized 3rd party C library:
```C
using ErrorCode = int;
using Handle = void*;
using FooHandle = Handle;
using BarHandle = Handle;
struct ArrayOfHandles {
int size;
Handle* data;
};
struct AllHandles {
ArrayOfHandles foos;
ArrayOfHandles bars;
};
ErrorCode GetAllHandles(AllHandles* into);
```
The current LLDB feature-set allows attaching a synthetic children
provider to `AllHandles`, but the scripted frontend has no chance to
select an appropriate alternative frontend implementation class for
`foos` and `bars` based on type information it is aware of.

[LFI][AArch64] Fix Segfault due to infinite recursion in LFI rewriter (#210267)
When emitting a deferred LR guard, if debug info is enabled, the
emission of the guard instruction can trigger temporary labels (e.g. for
DWARF line entries), which recursively calls onLabel. Since
DeferredLRGuard was only set to false after emission, the nested call
would re-emit the guard, causing infinite recursion which leads to a
SegFault due to stack overflow. This was detected compiling
ubsan_minimal_handlers.cpp in compiler-rt. I fixed it by using the
existing recursion guard (Guard).

[lldb] Add an artifact provider mechanism to Diagnostics (#210417)
Add a hook that lets a subsystem contribute a file to the diagnostics
bundle, without breaking layering and making Core depend on it. A plugin
registers an ArtifactProvider callback and a file name via AddArtifactProvider.
Providers run when a bundle is collected, and each one that yields
content is written into the bundle and recorded in the report's
attachments.
This restores, in a simpler form, the collection point that the removed
Diagnostics callback mechanism offered. The motivating consumer is the
downstream Swift health check, which registers a provider to write its
"swift-healthcheck.log" into the bundle. Unlike the old callback, a
provider does not open or write its own file: it just returns the
contents as a string and Diagnostics handles the rest.

must be indexed with the same bounds as the original array.
Carry the acc.bounds as optional operands on acc.reduction_init so this
indexing information is directly available. The operands are optional,
so scalar/whole-array reductions and existing IR are unaffected.

[CIR] Add x86_64 scalar calling-convention lowering (#209636)
CallConvLowering can already classify a function through the MLIR test
target or through a classification injected as an attribute, but it has
no
path to a real target ABI. This adds a `target=x86_64` mode that runs
the
LLVM ABI Lowering Library's System V x86_64 classifier: it maps CIR
types to
`llvm::abi` types, calls the classifier, and converts the result back
into
the `mlir::abi::FunctionClassification` that `CIRABIRewriteContext`
already
consumes.
To keep the first step small this handles scalar signatures only --
integer
up to 64 bits, pointer, bool, `f32`, and `f64`. Anything else (records,
arrays, vectors, `_Complex`, wide or uncommon floats, `_BitInt`,
`__int128`,
member pointers) is reported as not-yet-implemented through
`emitOpError`, so
an unsupported signature fails the pass instead of being silently
misclassified. Those types come in stacked follow-ups. The pass is still
only reachable from `cir-opt`; wiring it into the `-fclangir` pipeline
is a
later change.

[CIR] Add support for lowering __builtin_c23_va_start in ClangIR (#208741)
C23 `va_start `expands to `__builtin_c23_va_start`, which was previously
routed to the unimplemented-builtin NYI path in ClangIR. As a result,
variadic code failed to compile with -fclangir in -std=c23 mode.
This change lowers `__builtin_c23_va_start` the same way as
`__builtin_va_start`. For both builtins, the va_list operand is always
argument 0, so the existing lowering logic can be reused directly.

(`--ssaf-source-transformation=`,
`--ssaf-global-scope-analysis-result=`, `--ssaf-src-edit-file=`,
`--ssaf-transformation-report-file=`) under `SSAF_Group`, marshalled
into `FrontendOptions`. The compilation-unit identifier flag introduced
earlier is reused. The driver forwards all four flags to `cc1`.
Adds twelve `warn_ssaf_*` diagnostics under
`-Wscalable-static-analysis-framework` (`DefaultError`) covering the
orphan-flag matrix, unknown transformation names, unknown output
formats, WPA-suite read failures, and edit/report write failures.
Adds `clang::ssaf::SourceTransformationFrontendAction` — a
`WrapperFrontendAction` that, when any source-edit flag is set,
validates the CLI as a group, loads the WPASuite from the configured
path, instantiates the named transformation, and serializes the
accumulated edits and findings through the configured formats. The
action is wrapped in `ExecuteCompilerInvocation` after the existing
TU-summary wrap so both pipelines stack as independent `ASTConsumer`s on
the same translation unit; they exchange no data.

When used in sub builds like LLVM runtimes, it makes CMake to skip

[lldb/script] Add scripting extension template generator (#209647)
This patch adds a `scripting extension generate <ExtensionType>...`
command that introspects a Python extension base class and emits a
skeleton subclass with `# TODO: Implement` stubs for its abstract
methods (or, with `-a`, every method), then opens the result in an
editor.
Generated imports use `from <module> import <class>`, and the generated
`__init__` forwards its arguments to `super().__init__(...)` since every
base class relies on its constructor to set up attributes
(`self.target`, `self.process`, ...) that inherited, non-overridden
methods depend on. When the host can't open an external editor (e.g.
non-macOS), the command reports that as a message rather than an error,
since the file is already written.
To catch regressions in the generator itself instead of just checking
that a file was produced, this patch adds
`TestScriptingExtensionGenerate.py`, which generates a template for
every extension kind on the fly and drives it through a live lldb
session (`process launch -C`, `breakpoint set -P`, `target stop-hook add
-P`, etc.).

[CIR] Introduce loop cleanup regions (#210212)
For loops and while loops can create variables in their condition
regions that require per-iteration cleanup. The CIR dialect previously
had no clean way to represent these cleanups while maintaining a
separate condition region for the loop operation.
This change introduces an optional cleanup region to these loop ops and
updates the relevant region successor handling to reflect the insertion
of the cleanup region in the control flow when a non-empty cleanup
region is present.
The CFG flattening pass will handle routing the control flow through the
cleanup region in both the normal and EH unwind cases, but this is not
yet implemented. That will be added in a follow-up change, as will
creation of the cleanup region when it is needed during IR generation.

[lldb-dap][test] Avoid a hang on a test failure (#209988)
Tests in `TestDAP_server.py` create `DebugAdapterServer`, passing a
connection string. `DebugAdapterServer.__init__()` creates a socket and
passes the associated input and output streams to its parent class,
`DebugCommunication`. `DAPTestCaseBase.launch()`, which is called from
`TestDAP_server.run_debug_session()`, adds a teardown hook that
eventually calls `DebugCommunication.terminate()`. If the socket is not
closed when this hook executes, it waits indefinitely for the receiving
thread to join.
In the normal case, when a test passes, the connection is closed by
calling `self.dap_server.request_disconnect()` at the end of
`TestDAP_server.run_debug_session()`. If a test fails, the cleanup hook
is called while the connection is still active, which results in a hang.
This can be reproduced by removing the call to `request_disconnect()` or
by changing the condition in the `assertEqual()` on the previous line.
The fix passes the opened socket to 'DebugCommunication' and closes the
socket explicitly in 'DebugCommunication.terminate()'.

This PR upstreams the implementation and corresponding test suites for
X86 byte-shift intrinsics (pslldqi / psrldqi) spanning 128, 256, and
512-bit vector variants from the incubator.
I consolidated both left and right shifts into a single code path since
the underlying lane topology is identical, extracting the
direction-specific index arithmetic into clean variables at the top. Let
me know if you prefer this unified data-driven approach or if explicit
split functions for left/right shifts would be preferred for local
readability.
All integrated tests from the incubator have been upstreamed and are
currently passing.

[CycleInfo] Reference cycles by preorder index, not pointer. NFC (#210271)
The block-to-innermost-cycle map (BlockMap) and each cycle's parent link
hold a GenericCycle pointer. Store the cycle's preorder index instead,
so no raw cycle pointer remains in the stored representation: BlockMap
becomes a SmallVector<unsigned>, four bytes per block rather than eight,
and the parent link becomes ParentIndex.
The flat Cycles array does not exist during construction, so both hold
creation-order indices into the temporary forest until flatten()
resolves them to preorder indices.

[MLIR][WasmSSA] Instruction parser refactoring of WasmSSA importer (#195500)
Refactored WasmSSA importer mechanism to dispatch control flow to
relevant parser based on op code.
This is to prepare for instructions with multi-bytes opcodes (e.g.
vector instruction and some scalar instructions extensions) which will
be able to reuse the same mechanism.
It also replaces the bit tree to find the address by a jump table.

[SampleProfile] Support MD5-based ProfileSymbolList (#210235)
This patch speeds up sample profile loading by introducing an
MD5-based ProfileSymbolList (cold symbol list) in extensible binary
profiles.
The sample profile loader spends about a third of its time on loading
and decoding the symbol names in the Profile Symbol List section, yet
we use them only for membership checking purposes via
ProfileSymbolList::contains.
This patch teaches the writer to emit the section as an array of
64-bit GUIDs in the Eytzinger layout. The reader checks the
SecFlagMD5 section flag and sets up an EytzingerTableSpan
pointing into the mmap memory. This achieves both space efficiency
and runtime efficiency.
The new flag, md5-prof-sym-list, is off by default for now.
Profile merging is supported only from strings to an MD5-based
Eytzinger array.

[lldb][NativePDB] Fix width and signedness of enum constants (#210338)
Enumerator values aren't always encoded in the correct bit width and
signedness. This happens with both MSVC and Clang.
On MSVC, unsigned 64bit enumerators can be encoded as signed. For
example `ULONGLONG_MAX` will be encoded as `-1`.
Clang/LLVM will always encode the values as unsigned.
Example: https://godbolt.org/z/96YjGW48W.
I fixed this by setting the expected width and signedness when creating
the enumerator constant. We can't use a shell test like for the other
PDB tests, because no output shows the enum values.

[mlir][IR] Add SymbolUserTypeInterface (#198435)
This change adds SymbolUserTypeInterface, analogous to
SymbolUserAttrInterface, and extends SymbolTable verification to check
participating types.
Verification visits the types owned by an operation, (operand/result
types, block argument types, attribute-contained types, nested type
parameters) and checks each distinct type at most once, interrupting on
the first failure. Deduplication spans the whole symbol-table walk, so a
type used by multiple operations is checked only once.
Attribute (SymbolUserAttrInterface) verification also gets deduped the
same way.

Fixes #202782
When folding bufferization.to_buffer(bufferization.to_tensor(...)), only
create a memref.cast if the source and destination memref types are
cast-compatible.
This avoids asserting on unranked memrefs with different memory spaces
and leaves the original bufferization ops in place instead.

Refactor `AArch64AsmPrinter::emitPtrauthAuthResign` to improve

allowed to clobber address discriminator operands.
When resigning, do not clobber address discriminator register used for
authentication if it is also used for signing. Such clobbering would
prevent passing raw, 64-bit value as the new discriminator. Clarify
other corner cases of clobbering address discriminator operands.
Reuse `enum PtrauthCheckMode` instead of separate `ShouldCheck` and
`ShouldTrap` flags and drop its `Default` enumerator.

[orc-rt] Drop callManagedCodeAsync; tokens guard execution (#210508)
callManagedCodeSync is renamed to callManagedCode, and
callManagedCodeAsync is removed.
callManagedCodeAsync held a ManagedCodeTaskGroup token from the initial
call until the async continuation ran -- across the gap in which the
call is suspended and no managed code is executing. A token is meant to
guard managed code that is executing on a stack, so holding one across
that gap guards nothing while blocking shutdown.
callManagedCode holds a token only for the synchronous call to the
wrapped function, including anything the function runs inline on the
same thread before returning. An async function is called the same way,
with its continuation passed as an ordinary argument. Work deferred past
the function's return -- stashed, or handed to another thread -- runs on
a stack the token no longer guards; whoever later runs it is responsible
for ensuring a token covers it, acquiring one and aborting if the
acquire is denied.
See the new "Managed code execution and shutdown" section in
docs/Design.md for the full model (what a token guards, nested entries,
context-free acquire, and the abortability obligation).

[IR] Make semantics of strictfp consistent (#209465)
Although the section on constrainedfp in the LangRef clearly states "All
function definitions that use constrained floating point intrinsics must
have the strictfp attribute", indicating that a function with strictfp
calls must be marked with strictfp, the general description of strictfp
does not specify this. Refine its semantics and make it so, eliminating
the inconsistency.

[Support] Improve the logic for re-raising signals (#177864)
On most systems, checking `si_pid` is not actually valid unless
`si_code` equals one of the relevant signal codes (`SI_USER`,
`SI_QUEUE`, and on some OSs, `SI_LWP`), or the signal is `SIGCHLD`. So
on e.g. NetBSD, we would misinterpret the `SIGSEGV` fault address as the
sending PID and incorrectly conclude that the signal came from a
different process.
But as far as I can tell, there's not even a valid reason for us to be
checking `si_pid != getpid()`, because the signal could very well have
been explicitly sent by another thread in the current process. So we
really just need to check `si_code` for the aforementioned signal codes.
Darwin is the exception because it just doesn't set `si_code` at all in
the case of the `SI_*` signal codes. So keep the old logic there, even
though it misses the corner case of signals sent by a thread in the
current process.
While here, I also changed the error check for Linux
`rt_tgsigqueueinfo()` as it was not at all clear to me how we would ever
see `EPERM` from sending a signal to the current thread. Besides, it's
sensible to go to the `raise()` path as a last resort regardless of how
`rt_tgsigqueueinfo()` failed (e.g. `ENOSYS` on an old kernel).

[RISCV] Add packed narrowing convert intrinsics (#210389)
Add RISC-V P-extension packed narrowing convert header APIs for `pncvt`
and `pncvth`.
The new APIs lower through generic IR: RV32 uses truncate / logical
shift plus truncate forms, while RV64 uses existing packed unzip shuffle
forms. This reuses the existing backend lowering and TableGen aliases
rather than adding intrinsic-specific lowering.
Tests cover Clang IR generation and cross-project header assembly checks
for RV32/RV64 spec-listed mnemonics.

constructed on the stack first and then moved to its final place on the
heap. This is unnecessary -- directly construct the analysis result in
its final place. Consequently, analysis results can be immovable.

[libc][math] Implement half precision lgamma function (#192834)
The implementation uses three distinct paths based on $|x|$:
- Small ($|x| < 0.66$): Fits a degree-12 Chebyshev for $h(t) =
\frac{\text{lgamma}(t) + \log(t)}{t}$, recovering $\text{lgamma}(t) = t
\cdot h - \log(t)$.
- Medium ($|x| \in [0.66, 3.37]$): Fits a degree-20 Chebyshev for $g(t)
= \frac{\text{lgamma}(t)}{(t-1)(t-2)}$
- Stirling ($|x| > 3.37$): Uses $(x-0.5) \cdot \log(x) - x +
\frac{\log(2\pi)}{2}$ plus 1/2/4/8-term Bernoulli corrections by
sub-range.
Special cases: NaN, +/-Inf -> +Inf, +/-0 pole, negative integer pole,
lgamma(1) = lgamma(2) = 0 exactly, overflow for large positive x.
Exhaustive tests pass in all 4 rounding modes.

[AMDGPU] Run early-cse<memssa> at the end of the full-LTO pipeline (#208461)
The regular (non-LTO) and ThinLTO function simplification pipelines run
an
EarlyCSE-with-MemorySSA pass near the start of the function pass
sequence, but
the full-LTO postlink pipeline does not. Without it, a redundant
load/store
round-trip can survive all the way to codegen; the later GVN/DSE in the
LTO
pipeline do not catch this particular pattern.
Rather than touch the target-independent LTO pipeline, register
early-cse<memssa> through the AMDGPU FullLinkTimeOptimizationLast
extension
point, so it runs at the end of the full-LTO middle-end (before codegen)
only
for AMDGPU.

[MC] Pack scheduling class entry counts (#202649)
Generated scheduling classes currently use at most 20 write-resource
entries and 35 write-latency entries, while read-advance counts reach
504. Narrow the two write counts to `uint8_t`, order the three table
indices before the three counts, and emit target-specific compile-time
bounds assertions in generated subtarget source.
This reduces `sizeof(MCSchedClassDesc)` from 14 to 12 bytes in release
builds and from 20 to 16 bytes with debug fields. Fully stripped arm64
`llvm-mca` decreases by 544,896 bytes (1.49%), and the stripped
all-tools multicall binary decreases by 528,376 bytes (0.368%).

[mlir][bufferization] Fix stale BufferOriginAnalysis in BufferDeallocationSimplification (#210105)
Fixes #205228
This change fixes a use-after-free bug in the
BufferDeallocationSimplification pipeline caused by the greedy pattern
rewriter deleting operation tracked by the BufferOriginAnalysis.
BufferViewFlowAnalysis (internally used by BufferOriginAnalysis) creates
the dependencies map once during initialization. In this specific case,
the folder removed the `memref.cast` ops making later uses a
use-after-free bug.
Below is the snippet of running the pass using
`-debug-only=greedy-rewriter`. It erases a `memref.cast` and crashes in
RemoveDeallocMemrefsContainedInRetained.
```
...
[greedy-rewriter:1] //===-------------------------------------------===//
[greedy-rewriter:1] Processing operation : 'memref.cast'(0x654d43d18670) {
[greedy-rewriter:1] %4 = "memref.cast"(%3) : (memref<?x?xf32, 1>) -> memref<4x4xf32, 1>
[greedy-rewriter:1]
[greedy-rewriter:1] } -> success : operation was folded
[greedy-rewriter:1] //===-------------------------------------------===//
[greedy-rewriter:1] ** Replace : 'memref.cast'(0x654d43d18670)
[greedy-rewriter:1] ** Modified: 'scf.yield'(0x654d43c97bb0)
[greedy-rewriter:1] ** Erase : 'memref.cast'(0x654d43d18670)
...
[greedy-rewriter:1] Processing operation : 'bufferization.dealloc'(0x654d43cbd7d0) {
[greedy-rewriter:1] %5 = "bufferization.dealloc"(%4#0, %1, %3) <{operandSegmentSizes = array<i32: 1, 1, 1>}> : (memref<f32, 1>, i1, memref<4x4xf32, 1>) -> i1
[greedy-rewriter:1]
[greedy-rewriter:1]
[greedy-rewriter:1] * Pattern (anonymous namespace)::RemoveDeallocMemrefsContainedInRetained : 'bufferization.dealloc -> ()' {
```
The fix is to disable folding and split the canonicalization patterns to
run separately. This way, the patterns that rely on BufferOriginAnalysis
still work because folding was disabled and BufferOriginAnalysis never
invalidated. Then, the canonicalization patterns still benefit from
folding.

[X86][APX] Reuse EFLAGS across multi-predecessor blocks via NF in optimizeCompareInstr (#208184)
Extend optimizeCompareInstr to reuse EFLAGS produced in predecessor
blocks (including via NF variants) when a compare is redundant, covering
multi-predecessor, dominating, and cyclic CFGs. Share the NF-clobber
removal helper with FlagsCopyLowering, correctly handle swapped and
immediate-adjusted flag reuse, and simplify EFLAGS live-in marking.
Adds MIR tests exercising multi-predecessor reuse over cyclic and
dominating CFGs, including a multi-level idom walk.

[AA] Use the cmpxchg merged ordering in getModRefInfo (#210545)
When a cmpxchg's address is NoAlias with the queried location,
getModRefInfo still reports sync effects if the cmpxchg is stronger than
monotonic, since an ordered operation constrains code motion around
locations it never accesses.
But a cmpxchg op has two atomic orderings, and getModRefInfo looked
only at one of them.
Change it so we check the merged ordering, i.e. the stronger of the two.

[orc-rt] Replace RunWrapperCall with generalized Dispatch (#210591)
RunWrapperCall dispatched wrapper-function calls, but the Session also
needs to dispatch continuations for results returned by the controller.
Replace it with a generalized Dispatch mechanism (DispatchFn) that is
handed an opaque Task for each unit of work, covering both.
QueueingRunner is correspondingly simplified: it no longer knows
anything about wrapper functions and just enqueues the Task it is given.
Tests and the noDispatch helper are updated to the new interface.

[InstCombine] Fix invalid fshl -> lshr fold when shift is vector with constant zero lane (#210606)
For vectors, this is not valid if a subset of the lanes are constant
zero. Doing this fold introduces poison in those lanes. A similar fix
was done for fshr in 46957a138dea339799059ea5bf032e40042ff185 however
the same issue seems to apply to fshl
