-----------
[SLP]Do not reuse transformed nodes in gathers emitted before their user
Gathers of the users with all scalars used outside the block are emitted
before the user, while the transformed nodes are emitted with the user.
Reusing such a transformed node postponed the gather and moved only the
last instruction of the transformed node buildvector, breaking dominance.

[SSAF] Extract the virtual method override relation per TU (#213316)
A virtual call may dispatch to any override of its callee, so a whole-program
analysis cannot reason about a method's parameters and return value in
isolation. It needs to know which method overrides which, and which slots
that relates. Collect this per TU, so a later pass can join the related
slots into families.
JSON serialization lands separately, so the summary is not writable via
`--ssaf-extract-summaries` yet.

[NFC][SLP][AMDGPU] Precommit a cross-block fmul fadd contraction test (#226609)
Two contract fmuls feed contract fadds in different successors. AMDGPU
sinks such an fmul into the block of its user and fuses the pair, so the
scalar form is one fma per path. Record the current behaviour, the pair
is kept scalar when the fmul is operand 0 of the fadd and paired when it
is operand 1.

Log Message:

[CIR][CUDA] Read fat binary in CIRGen and store its bytes on the module (#225971)
Two problems with the current implementation of GPU CIR:
1. `LoweringPrepare` read the fat binary from disk, via
`astCtx->getSourceManager().getFileManager().getVirtualFileSystem()`. A
transform pass should not do I/O, and this is one of the `ASTContext`
dependencies that keeps the post-CIRGen pipeline from being IR-to-IR.
Some of the related discussion on this has been done
[here](https://discourse.llvm.org/t/rfc-clangir-making-cir-pipeline-boundaries-first-class-driver-artifacts/90998)
and PR: #219048
2. `#cir.cu.binary_handle` stored the *file path*. That's a build input,
not a
property of the program: it bakes one machine's directory layout into a
`.cir`.
The PR removes the file path and adds an attribute
CIRGen now reads the file in and records the contents
as `#cir.cu.device_binary`, a `StringAttr` of raw bytes. The
attribute is deleted once LoweringPrepare "consumes" it.
A couple of notes:
1. The GPU dialect has a similar representation. We may want to move
towards that direction slowly, but I don't see any value doing this now.
It will confuse the direction of this PR.
2. The test `clang/test/CIR/Diagnostics/mlir-error-routing.cu` has
completely
changed, because it relied on an error occurring when the file attribute
was missing.
Since we deleted that attribute completely, the test was failing.

[Clang][OpenMP] Optimize `collapse` IV bit-width precision expression (#225612)
`collapse` used to build both a 32-bit and a 64-bit trip-count, then
keep one.
This patch does the same in `checkOpenMPLoop`:
If we know 32-bit is enough, build only 32-bit.
Else build 64-bit first.
Build 32-bit only when the product is a compile-time constant and fits.
Origin: `flatten` already builds only the width it keeps.

[libc++] Add static_assert diagnostics for LWG3133 named requirements (#212360)
Add a static_assert to both std::complex<T> and std::valarray<T>
requiring that T be a cv-unqualified object type that satisfies the
Cpp17DefaultConstructible, Cpp17CopyConstructible, Cpp17CopyAssignable,
and Cpp17Destructible named requirements, per the revised wording in
[numeric.requirements]. This mirrors the existing pattern already used
by std::optional<T>.
Non-_v (class-style) trait forms are used throughout so that the
assertion is well-formed even when <complex>/<valarray> are included in
C++03/11/14 mode.
Test coverage:
- A .verify.cpp for complex<T> and one for valarray<T>, each covering
six failure modes: cv-qualified types, and one type violating each of
the four named requirements individually.

[WebKit Checkers] Add built-in recognition for standard view types (#226350)
libc++ doesn't fully annotate `[[clang::lifetimebound]]` for all view
types. This results in false negatives in borrow checking.
Ultimately we need to fix this in libc++, but for now we can work around
the most common / most important false negatives. For example, borrow
checking can now check
for (auto& x : vector | std::views::reverse) { ... }

intended to be a NFC as-is, allowing it to be reused in global isel and
extended in the future to handle shuffles that are not part of the
shuffle table. The number of instructions generated can also be used for
costing shuffles, as we do for immediate generation.

[VPlan] Take wide induction wrap flags from the increment of the phi. (#226726)
The binary operator of an integer InductionDescriptor is the incoming
value from the latch, which is not required to have the phi as operand.
E.g. for
%x = add i32 %iv, 5
%iv.next = add nuw nsw i32 %x, 1
the flags only apply to %x + 1, while the induction step is 6, and %iv +
6 may wrap even though %iv.next does not. Determine the wrap flags from
the increment of the header phi instead, and only if it adds to or
subtracts from the phi directly.

https://github.com/llvm/llvm-project/pull/195823 added logic consider
vectorization of low trip count loops if there was no or a single
iteration remaining.
This causes loops to be vectorized with a VF where no scalar tail
remains, even if it is required for legality (loop with multiple
countable exits require scalar epilogue to pick the exit).
For now, limit to cases where there's a scalar iteration remaining.

[M68k] Finish implementation of `MOVX` (move and extend) pseudo-instructions and fix related errors (#218938)
This patch adds remaining addressing modes to the "move and extend"
pseudo-instructions, and fixes a few errors and inconsistencies in the
logic that caused inefficient code generation.
- Remaining addressing modes were implemented to match non-pseudo `MOVE`
instructions.
- Names of the pseudos now correctly reflect the register classes they
operate on, e.g. `MOVZXd32r16` for XR16 -> DR32.
- Fixed an issue where `MOVZX` could be allocated to an address
register, which has no way to zero-extend the result. (There were even
some of these in the test `register-spills.ll`, emitted as illegal
instructions, but the test doesn't have instruction verification
enabled, so it wasn't caught.)
- Fixed some `extload` patterns where the register was unnecessarily
extended to 32 bits before being truncated to its final size, causing
redundant instructions to be omitted.
- Fixed `anyext` patterns lowering to `MOVZX` instead of `MOVX`, causing
unnecessary zero-extensions.
- An inconsistency was fixed where the expansion logic would perform a
source-sized move when loading from memory, but a destination-sized move
when moving between registers. They now always perform a source-sized
move, which improves clarity in the assembly output and has more
opportunity for future optimizations.

[RISC-V][LTO] Add baseline tests for LTO inline assembly and mapping symbols (#225129)
No functional change intended here, just adding test coverage for RISC-V LTO
inline assembly ABI handling (following up on
https://github.com/llvm/llvm-project/pull/223606) and for the `$x<arch>` ELF
mapping symbols emitted for module and function target features.
The `TODO`s for `.lto_discard` dropping module inline asm target features and
for the missing/duplicate `$x<arch>` mapping symbols will be addressed in the
following commits.

[LTO] Preserve module inline asm target properties for .lto_discard and symvers (#225130)
Previously, LTO::addRegularLTO() and IRLinker::run() called
prependModuleInlineAsm() and appendModuleInlineAsm() with a plain string when
synthesizing `.lto_discard` and imported `.symver` directives, creating a new
GlobalAsmFragment with empty TargetCPU and TargetFeatures instead of preserving
the existing module inline asm's properties. Copy the front fragment's Props so
these synthesized directives are merged into the module's inline asm with the
same target features.

[RISC-V][MC] Fix mapping symbol section tracking on popSection() (#225131)
Previously, RISCVELFStreamer::changeSection() saved LastEMS and LastEmittedArch
under getPreviousSection().first instead of getCurrentSection().first. When
MCStreamer::popSection() switches back to a previous section,
getPreviousSection() already points to the destination section being restored
rather than the section being exited. This clobbered the destination section's
saved mapping symbol state and caused duplicate `$x<arch>` mapping symbols to
be emitted whenever returning to `.text`.
Use getCurrentSection().first instead, matching AArch64ELFStreamer and
ARMELFStreamer.

[RISC-V][MC] Update ELF streamer ArchString in setFlagsFromFeatures() (#225140)
During LTO, the TargetMachine subtarget is initialized with the linker's
default CPU (e.g. `generic-rv64`, `rv64i2p1`), while
RISCVAsmPrinter::emitStartOfAsmFile() reconstructs the module's actual ISA from
the `riscv-isa` module flag and calls RISCVTargetStreamer::setFlagsFromFeatures()
and RISCVTargetStreamer::emitTargetAttributes(). Because
RISCVTargetELFStreamer previously only initialized InitialArchString and
ArchString in its constructor rather than in setFlagsFromFeatures(), direct
object emission bypassed the update and tagged `.text` with `$xrv64i2p1`
instead of the module's full architecture string.
Move the InitialArchString and ArchString initialization into
RISCVTargetELFStreamer::setFlagsFromFeatures() and also call setArchString()
alongside emitTextAttribute(RISCVAttrs::ARCH, ...) in
RISCVTargetStreamer::emitTargetAttributes().

[RISC-V] Update streamer ArchString in emitTargetFeaturePush() (#225133)
Previously, RISCVAsmPrinter::emitTargetFeaturePush() only emitted `.option push`
and `.option arch` without updating the streamer's active ArchString. When
emitting an ELF object file directly (`-filetype=obj`),
RISCVTargetELFStreamer::emitDirectiveOptionArch() is a no-op while
emitTargetFeaturePop() resets ArchString back to the pushed ArchString, so
module-level inline assembly and functions with custom `target-features` failed
to emit updated `$x<arch>` mapping symbols.
Call RTS.setArchString() with the parsed ISA string in emitTargetFeaturePush()
so `-filetype=obj` records the active `$x<arch>` mapping symbol alongside
`.option arch`.

[orc-rt] Simplify ConnectorRegistry::connect and ogre setup. (#226772)
ConnectorRegistry::connect and ConnectorFn now take the Session and
BootstrapInfo directly, replacing the GetAttachInfo callback and the
AttachInfo struct. The callback let the Session be built lazily, after
the connector had validated its spec, but a connection can fail after
validation anyway, so callers already had to handle discarding a Session
built for a failed connection. Build the Session first, then connect.
ogre's setup is restructured to match: makeSession detects the process
info, builds a thread-pool dispatcher and the Session, adds the host
services, then connects; runOgre waits for the detach. Errors are
reported via Session::logErrors when logging is enabled.
SocketConnectorTest now connects a real Session. Its ownership test
adopts a non-stream socket, which the connector accepts and
createSimpleRemoteCAOverSocket then rejects, rather than relying on a
failing GetAttachInfo.

[clang-tidy] Fix redundant-branch-condition false positive in loops (#225827)
Fixes #205685.
`bugprone-redundant-branch-condition` decides whether the condition
variable changes between the outer and inner `if` by comparing source
positions. When a loop sits between the two, a mutation that comes after
the inner `if` in the source still runs before the inner condition is
evaluated again on the next iteration, so the check reports a redundant
condition that isn't, and the fix-it changes behavior.
The fix walks the parents of the inner `if` up to the outer `if` and
finds the outermost enclosing loop. If the variable is mutated anywhere
in that loop, the check does not warn. This follows NagyDonat's
suggestion in the issue: the existing check already covers mutations
between the outer condition and the loop, so only the loop itself needs
the extra query. The walk passes through declarations, so an inner `if`
inside a lambda stored in a variable is handled too, and it stops at the
enclosing function. I chose a syntactic walk instead of the CFG
(`utils::ExprSequence`), since it covers the range the issue asks for
without building a CFG on every match.
Tests cover `for`, `while`, `do`, and range-based `for`, a mutation in a
`do`/`while` condition, a lambda stored in a variable inside the loop,
and an inner loop whose enclosing loop does the mutation. Each of these
warns without the patch. Three positive cases confirm the warning is
kept when the loop never mutates the variable, when the mutation comes
after the loop, and when the loop encloses both `if` statements.
Limitations:
- Any mutation in the loop suppresses the warning, including one
followed by an exit from the loop (`break`, `return`, `throw`) or one
that cannot make the condition false. The inner condition is still
redundant in those cases; telling them apart needs the CFG. I added the
`break` case under Unhandled Cases. The change only removes warnings, so
it adds no new false positives.
- Loops built with `goto` and Objective-C `for ... in` loops are not
recognized, so the false positive remains there.
I used Claude to help write the code. I tested and reviewed all of it
myself, and worked through the approach and suggestions with Claude.

[TTI] Provide conservative legality + costs for @llvm.speculative.load. (#180036)
Add TTI support for @llvm.speculative.load, including cost and legaltiy
checking support.
The initial implementation for AArch64 checks if the loaded type is
<= 16 bytes, and only considers such cases legal due to MTE.

[DAG] Scalarise trivial splat operations (#226257)
This fixes an issue reported on #224255, where a single active lane
masked store is converted to a v1f16 extract_subvector, which becomes a
v1f16 splat, which fails to scalarize. Add the necessary trivial
scalarisation of the splat by using the f16 input operand.
(I was originally going to fix this by generating a scalar f16 extract
directly (which would have the benefit of treating f16 as legal), but
that seems to cause a regression in 2 x86 tests).

[libc++][docs] Convert documentation from reST to Markdown (batch 1) (#221513)
This is the first batch of changes to migrate libc++ documentation from
rst to markdown.
I use a local pixel diff tool to compare the rendered HTML, and all
diffs seem like fixes. They tend to fall into the following categories:
- dashed bullet lists were previously not rendered, but now they are
- extra indentation interpreted as blockquotes has been removed
- single backticks are now codefont spans, not italic spans
Tracking issue: #201242
See the [migration guide] for more information.
[migration guide]:
https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines
This is a stacked PR based on #221512, which will be a standalone commit
that
renames *.rst -> *.md before this PR lands for history preservation
purposes.

[SimplifyCFG] Cost speculated selects with their real scalar condition (#217664)
`validateAndCostRequiredSelects()` priced the selects that
`speculativelyExecuteBB()` would create using
`CmpInst::makeCmpResultType(PN->getType())` as the condition type. For a
vector phi, that asks the target for the cost of a per-lane vector
select, but the select actually created uses the branch condition, which
is always a scalar `i1`.
This only changes behaviour where a target's cost model distinguishes
the two condition types. Of the targets checked, only AArch64 does.
This may worsen the compiler's output in RISC-V, X86, ARM, so no
intention to merge soon before collecting more feedback on how the
different targets should communicate this property.

[libc++][AIX] Add system library path via blibpath for lldb (#223837)
On AIX some tools we use for testing libc++, like lldb, are linked
against the system libc++, which has additional members (e.g
`shr2_64.o`) that the newly built libc++.a doesn't have. But the current
test harness set the `LIBPATH` to point at the newly built libc++, which
can load break these tools.
This change removes the `LIBPATH` and instead sets the `blibpath`
(equivalent to rpath on other systems), which helps lldb find the system
libc++.a, while still running the tests against the libc++ build under
test.

InstExclusionSet, VPCSEDenseMapInfo, MachineInstrExpressionTrait --
keeps its own hash. Any other key hashes through a thunk, one per
(KeyT, KeyInfoT) whatever the map's value type.
SmallDenseMap's in-place rehash for remove_if shares the loop through
`rehashRelocatable`. It rehashes once rather than into a temporary map
and back, which can reorder a probe chain that wraps around the table.
Building clang takes 0.86% fewer instructions and the binary is 0.64%
smaller.

[libc++][format] Don't leave the output buffer full after a bulk write (#226791)
__output_buffer::push_back writes a code unit before it makes room, so
the buffer must always have a free one. __copy, __transform and __fill
write in chunks of the available space and could end with the buffer
full. Formatting into a back_insert_iterator of a string, vector or
deque goes through a 256 code unit buffer, so an argument or fill whose
length is a multiple of 256, followed by a literal, wrote that literal
past the end of the buffer.
Make room in a full buffer at the end of these functions, as push_back
does.

[flang][OpenMP] Support allocate clauses on scope constructs (#221229)
Flang already lowers OpenMP 5.2 `allocate` clauses on `scope` constructs
to `omp.scope`, but LLVM IR translation previously rejected them.
This change maps allocation operands to their corresponding private or
firstprivate slots and reuses the existing allocator-backed
private-storage and OpenMPIRBuilder allocation/free paths.
Support is currently limited to host-side fixed-size intrinsic scalar
private and firstprivate variables, including SAVE variables and
individually listed COMMON-block members. Arrays, descriptors, pointers,
allocatables, derived types, named COMMON-block list items, and
target/device allocation remain unsupported.

[ADT] Extract DenseMapStorage from DenseMap (NFC) (#226664)
This patch extracts the bucket and occupancy storage management from
DenseMap into a new helper class, densemap::detail::DenseMapStorage,
and updates DenseMap to use it via composition.
DenseMapBase::Rep is also moved to densemap::detail::StorageRep so
that DenseMapStorage::getRep() can return it directly.
This is part of the effort to replace CRTP in DenseMapBase with
composition (see #168255). I'm planning to post a similar patch for
SmallDenseMap before actually removing CRTP.

[libc] Migrate file I/O syscall wrappers to syscall_checked (#226477)
Migrate a batch of related file descriptor and core I/O syscall wrappers
to use syscall_checked instead of manual syscall_impl error checking.
While in there:
- update file headers to the new style
- reformat includes into a single block so clang-format can sort them

CodeGen: Fix SplitCriticalEdge using wrong VNInfo for subranges (#226214)
This fixes verifier errors when LiveIntervals is run before phi
elimination.
When extending a live interval across a newly split critical edge for a
PHI source operand, the subrange segments were added using the VNInfo of
the main range instead of the subrange's own value. Look up the
subrange's value at the predecessor's last index, as the other subrange
loop in the same function already does, and skip subranges with no value
there.

TargetMachine: Remove pointer-size query methods (#226404)
Remove the shim methods from the TargetMachine's copy of the DataLayout,
which will soon be eliminated. The Module owns the authoritative DataLayout,
so callers should read the value from the contextual Module.
Completely unreasonably, Mips's ABI name can change the pointer size which
we probably should just not support. Many other triple checks will never be
correct. This avoids potential mismatches in these contexts, but I still expect
this to be widely broken.
Some of the TargetLowering constructor changes and AMDGPULegalizerInfo
changes are kind of annoying. We could pass in the DataLayout through the
subtarget constructors but it didn't seem worth the effort and the information
should be derivable from the triple anyway.

[orc-rt] Add initial C addressing regression tests. (#226901)
Add tests that check that JIT'd C code can address data, both in the
same object and in other objects. Each test covers a single construct
(e.g. a load of static data, or a pointer to an array element in another
object stored in initialized data), since linker/loader bugs usually
crash the JIT'd program, and a crash identifies only the failing test.
Each test runs at -O0 and -O2.
To support multi-object tests, add a split-file substitution and lit
feature, and accept .test files in languages/c.
Update the README's test conventions to match: one construct per test,
"Check that" and "Stresses:" header comments, -O0 and -O2 RUN lines, and
guidance on keeping constructs alive under optimization without hiding
the optimized lowering.

SPSProxySpecTest). Also remove the blocking callWrapper convenience
methods, which have no remaining users.
Add a "How to call functions in the executor" section to
llvm/docs/ORCv2.md describing Proxy, controller-interface descriptors
and sps::ProxySpec, how lookupAndApply and recordProxy resolve proxies,
and how to migrate from callSPSWrapper.
Clients calling these methods directly should migrate to Proxy; see "How

[AMDGPU] Add wait states between different MFMAs sharing an accumulator (#218363)
A full-register src2/C read after an MFMA write emits no wait states,
relying on accumulator forwarding that only works while the chain stays
on one MFMA. Two different MFMAs sharing an accumulator instead need the
wait states of a partial overlap: on gfx950, v_mfma_f32_16x16x32_f16
then
v_mfma_f32_16x16x16_f16 on the same tuple needs 5 and got none. Compare
canonicalized opcodes so mac and register-bank forms still match.

#224360 made fixupDebugInfoPostExtraction reuse the existing

multiple times, as occurs with cold/hot code splitting.
This PR is the trivial fix of restricting this change to only apply if
there is a single user of the expression.
I've also added an additional verifier guard to capture these failures.
Fixes #226848
AI usage: Claude used to find a way to construct
dbg-value-arg-index-out-of-range.ll so that I could add a verifier guard
that bypassed the other existing verifier guards.

Reland [flang] Support scoped LICM and OpenACC capture provenance (#225401) (#226909)
Follow compute-region capture operands when checking whether scalar and
scalar-descriptor loads are safe to speculate. Preserve the existing
optional, array-element, and loop-modification safety checks.
Add an optional only-inside operation-name selector while retaining
function-scoped alias analysis. Resolve the name once per function and
compare interned operation names during ancestor traversal. The default
continues to select all loops. An explicit name selects loops with a
matching ancestor within the function, including the function itself.
Cover capture safety, host exclusion, non-OpenACC and nested scopes,
loop boundaries, unmatched names, and the function boundary.
The motivation for this is to allow running LICM only on device relevant
loop at O0.
Reland #225401 with CMakeFiles.txt change to fix shared library builds.

[X86] Select standalone ~(-1 << n) masks as BZHI (#226158)
InstCombine canonicalizes (1 << n) - 1 to xor (shl -1, n), -1. When that
mask feeds an AND, X86DAGToDAGISel::matchBitExtract folds the whole
expression into BZHI, and the add form is selected as BZHI even on its
own because Select enters matchBitExtract from ISD::ADD. The xor form on
its own is not: a mask that is returned, stored, or consumed by anything
but AND is selected as mov -1; shlx; not.
Enter matchBitExtract from ISD::XOR too under BMI2, so the standalone
mask becomes mov -1; bzhi. That is one instruction shorter and avoids
the shlx+not dependency chain. BMI1-only targets keep the shift form,
since BEXTR would need the count moved into bits 15:8 first.

[mlir][memref] Enforce consistent reinterpret_cast metadata (#217338)
This PR implements [[RFC] Clarify `memref.reinterpret_cast` Verification
of Dynamic
Metadata](https://discourse.llvm.org/t/rfc-clarify-memref-reinterpret-cast-verification-of-dynamic-metadata).
## Context
`memref.reinterpret_cast` describes its result through both its mixed
offset/size/stride metadata and its result `MemRefType`. Currently,
verification allowed a dynamic result-type correspond to static
operation metadata, introducing inconsistent descriptors.
For example, the verifier permits:
```mlir
%r = memref.reinterpret_cast %base
to offset: [0], sizes: [%n, 2], strides: [%s, 1] : memref<f32>
to memref<?x?xf32, strided<[?, ?], offset: ?>>
```
where the operation constructs a descriptor with a statically known
second size and stride, but the result type does not expose those facts.
## Changes
This PR consolidates the verifier to require `reinterpret_cast` result
type’s sizes, offset, and strides to exactly match the static/dynamic
representation and values of the operation metadata.
Transforms that create `memref.reinterpret_cast`, including GPU memref
decomposition and strided-metadata expansion for `subview` and
`collapse_shape`, now derive the result type from the final, potentially
folded descriptor instead of inheriting the original operation’s result
type.
When this descriptor-derived type differs from the original result type,
the rewrite inserts a `memref.cast` back to the original type. These
rewrites are not type-conversion patterns, so their existing
users—including function returns and calls—must retain their original
types. Identity stride layouts are canonicalized when possible to avoid
unnecessary explicit layouts and casts.
Tests are updated to use result types consistent with their
`reinterpret_cast` metadata. In the SPIR-V tests, the size `10` is
represented by an SSA value because those cases intentionally remain
dynamically shaped and lower to element pointers; making the size static
would change the SPIR-V pointee type and prevent the existing
`reinterpret_cast` lowering from applying.
A regression test also verifies that folded `subview` offsets and
strides are reflected in the generated `reinterpret_cast` type.

[mlir][tosa] Add assembly format for CONST (#226147)
This commit adds an assembly format for the TOSA CONST operation.
Previously, the generic assembly format was used while all other
operations had a custom format. It takes advantage of the incoming
textual format changes in #217291, to minimise impact to downstream
consumers.

[GVN] Decouple GVNValueTable and GVNPass (NFC) (#226232)
This is a first patch in series with the ultimate goal to move `GVNPass`
out of `GVN.h` and into `GVN.cpp`.
This is not straightforward because because of the rather tangled
dependencies between `GVNPass`, `GVNHoistPass`, `ValueTable`, and
`LeaderMap`.
The `GVNHoistPass` pass references `GVNPass::ValueTable`, by peeking
into `GVNPass`, resp. including `GVN.h`. Since `GVNHoistPass` does not
actually depend on `GVNPass` itself, but only on the `ValueTable` it
contains, it would make more sense to move `ValueTable` out of `GVN.h`
to its own header file, to be included by both `GVN.h` and
`GVNHoist.cpp.`
That's not entirely straightforward either since `ValueTable` has
several member functions taking a `GVNPass` reference as an argument.
This prevents moving `GVNPass` out of `GVN.h` and into an anonymous
namespace in `GVN.cpp`.
These `GVNPass` (in `ValueTable`) references are only used to access the
`LeaderMap`. Consequently, `LeaderMap` can be moved out of `GVNPass` and
into the `llvm` namespace and forward declared for its uses by
`ValueTable` (when `ValueTable` gets its own header).
This patch moves the `LeaderMap` out of `GVNPass`, into the `llvm`
namespace, and renames it to `GVNLeaderMap`.

[X86] Shrink i32 unsigned compares to i8/i16 when high bits are zero (#197801)
Shrink i32 compares to 8 or 16 bit for non-constant operands when high
bits are zero, following the precedent of i64 -> i32 case.
Fixes the cases in #196827 where both sides of the compare are
non-constants, as this allows the `and(X, mask) `to be eliminated
downstream in DAGCombine.
I believe we can extend to constant operands as long as the length
changing prefix problem for i16 immediates is accounted for - however:
1. it's not sufficient to fix the remaining cases in the motivating
issue alone: when the rhs is constant, InstCombine clear the bits in the
mask that does not affect the comparison result (`icmp (and X, 255),
123` -> `icmp (and X, 252), 123`), so the mask does not fill the full
width of the truncated type, making the analysis trickier.
2. it leads to a lot of check line drifts, i'm not sure if it's worth
the effort to account for all of them, even if most don't look like
regressions.

A call to a function without debug info does not need a debug location,

```
inlinable function call in a function with debug info must have a !dbg location

Before redirecting such a call, give it a line 0 location in the scope
of the caller, as `DwarfEHPrepare` does for the call to the rewind
function. This covers both ways calls are redirected:
`replaceDirectCallers()`, and `replaceAllUsesWith()` for `unnamed_addr`
functions.

[MLIR][NVVM] Add SM version requirements to mbarrier Ops (#224105)
The mbarrier Ops had no `NVVMRequiresSM` trait, so a `gpu.module`
targeting an older chip (e.g. `sm_75`) accepted them, and the error only
showed up later. This adds the trait to all 13 of them, same as #192257
and `mbarrier.check_layout` in #217252.
| floor | Ops |
|---|---|
| `sm_80` | `init`, `inval`, `arrive`, `arrive_drop`,
`arrive.nocomplete`, `arrive_drop.nocomplete`, `test.wait` |
| `sm_90` | `expect_tx`, `complete_tx`, `arrive.expect_tx`,
`arrive_drop.expect_tx`, `try_wait`, `try_wait.parity` |
The floors come from the Target ISA Notes in the [PTX ISA
8.5](https://docs.nvidia.com/cuda/pdf/ptx_isa_8.5.pdf) (section
9.7.12.15), and they match the backend: every Op that lowers to an
intrinsic fails to compile one arch below its floor and compiles at it.
`arrive_drop` at sm_80 relies on #222916.
Since the trait is per Op, some settings that need sm_90 still get
through on sm_80: an explicit `count`, `scope = cluster`, a
`shared::cluster` pointer, `relaxed = true`, or `layout` on `init`.
Catching those would mean the Ops implementing `getRequiredMinSMVersion`
themselves, which no Op does yet. Happy to add that if you'd like. PTX
version isn't covered either (#69448).
One behaviour change: `gpu-lower-to-nvvm-pipeline` and
`nvvm-attach-target` default to `sm_75`, so using mbarrier Ops with that
default now fails earlier, with a clear message. `verifyTarget = false`
turns the check off.
Tests are in `nvvm_check_target_sm.mlir`: one failing case per Op just
below its floor, plus passing cases at the floor, above it, and on
`sm_90a`.

Log Message:
-----------
[VPlan] Distribute execution frequencies with BlockFrequencyInfo's code. (#226841)
Instead of hand-rolling frequency propagating, manually construct BFI
and use BFI::distributeMass.
Adds a final step where frequencies are rounded up to at least one, to
distinguish between unreachable and almost never executed blocks. This
matches BFI behavior.
Note that we need to still track whether frequencies are from edges with
unknown profile info.
