Git commit e2c8f57f00971712c1732b137a9afc539e38ff37 by GitHub (on behalf of Robert Imschweiler) on 03/08/2026 at 06:28..
[OpenMPOpt] Null generic-mode wrappers for SPMDized kernels (#207611)

If a kernel gets SPMDized, it doesn't need the wrapper function that is
passed to __kmpc_parallel_60. Keeping the dead wrapper function can lead
to lots of misleading "local memory global used by non-kernel function"
AMDGPU backend warnings.
Let OpenMPOpt null the wrapper argument such that DCE can then remove
the corresponding dead functions.

[flang-rt] enable IsNamelistNameOrSlash lookahead for scalar namelist items (#211224)

Resolves https://github.com/llvm/llvm-project/issues/211747

Problem
-------
An empty NAMELIST assignment on a scalar item — e.g. `l =` in

    &nml l= i_count=7 r_value=2.72/

— aborted at runtime with

fatal Fortran runtime error: Bad character 'i' in LOGICAL input field

Every EditIntegerInput / EditRealInput / EditLogicalInput /
EditCharacterInput function starts its list-directed arm with

    if (IsNamelistNameOrSlash(io)) return false;   // no value

which peeks ahead (via SavedPosition, no stream consumption) for a
`<name>=` / `<name>%` / `<name>(` shape or one of the terminators `/`
`&` `$`, letting the reader bail cleanly for empty values and
short-array ends. That helper's first line is

    if (!listInput || !listInput->namelistGroup()) return false;

InputNamelist however called ResetForNextNamelistItem with
`useDescriptor->rank() > 0 ? &group : nullptr`, so `namelistGroup_`
stayed null for scalars. The peek was silently disabled and the value
reader consumed the next namelist item's name as a bare token, producing
the abort above. Legacy nvfortran / gfortran accept empty scalar
assignments as "keep current value".

Solution
--------
Pass `&group` unconditionally to `ResetForNextNamelistItem`. Today
`IsNamelistNameOrSlash` uses `namelistGroup_` only as a boolean gate
(never as a lookup table), so widening it is a no-op for arrays and
enables the same empty-value / next-name detection for scalars.
NamelistTests.NanInputAmbiguity (which motivated the original pointer
form) still passes; three new tests cover the empty-scalar case, the
empty-array case, and an empty scalar surrounded by arrays.

Enforce single-operand form for llvm.loop.vectorize metadata (#210932)

This patch implements Phase 2 of the RFC "Enforce Single-Operand Format
for All .enable Metadata Nodes". Please refer to RFC:

https://discourse.llvm.org/t/rfc-enforce-single-operand-format-for-all-enable-metadata-nodes/90571/

The two-operand boolean form !{!"llvm.loop.vectorize.enable", i1 0/1} is
replaced by a single-operand enable/disable pair:

  !{!"llvm.loop.vectorize.enable"}    ; force vectorization
  !{!"llvm.loop.vectorize.disable"}   ; suppress vectorization

The Verifier rejects the two-operand form, AutoUpgrade rewrites old
bitcode (including the legacy llvm.vectorizer.enable tag), and the
readers and producers across LLVM, Clang, MLIR and Polly are updated.

[clang][ast][objc] Implement getNameForDiagnostic for ObjC{Method,Property}Decl (#213030)

This overrides `getNameForDiagnostic` to provide a qualified name
representation for Objective-C methods and properties in diagnostics.
When qualified is true, it formats them using the standard Objective-C
syntax, such as `-[Class selector]` or `+[Class property]`. Previously
these would be `Class::selector` or `Class::property`. If qualified is
false, it falls back to printName.

Note that I avoided modifying `NamedDecl::getQualifiedNameAsString()` or
`printQualifiedName()` which will continue to (unfortunately) return
`Class::method`, but this is intentional to attempt to avoid any
breakage downstream due to output changing.

Git commit 2354dce21ab107d0350cea741923bcffbeb14d91 by GitHub (on behalf of Ashutosh Nema) on 03/08/2026 at 08:02..
[Transforms][Utils] Add LoopSplitUtils for iteration-space loop splitting (#205995)

Introduce LoopSplitUtils, a utility that splits a counted loop into a
chain of per-partition sub-loops covering contiguous slices of the
original iteration space. Given a loop and a list of partition ranges,
it clones the body per partition, guards each with an entry check that
skips empty partitions, clamps each latch to its slice, and rebuilds SSA
for loop-carried and live-out values so the result is
behaviour-preserving.

Key properties:
- Supports ascending (+1) and descending (-1) unit-step inductions, in
both signed and unsigned iteration orderings, with direction-aware
guard/latch predicates and end clamps.
- Reuses the original loop for partition 0 and clones the rest, exposing
per-partition value maps via getPartitionValue()/getPartitionValueMap().
- Lets callers drop the entry guard for a partition proven non-empty via
avoidPartitionGuard(); provably-empty partitions are always skipped.
- Patches the dominator tree and LoopInfo incrementally rather than
rebuilding them.

How to use:

  LoopSplitUtils LSU(L, LI, SE, DT);
if (!LSU.isLegal()) // counted, bottom-tested, LCSSA, unit step
    return false;
  // Tile the iteration space in order; e.g. split [Start, End] at K:
  LSU.addPartition(Start, K - 1);   // partition 0: [Start, K-1]
  LSU.addPartition(K, End);         // partition 1: [K, End]
  LSU.split();
  // After split(), query a cloned value in a given partition:
  Value *V1 = LSU.getPartitionValue(Orig, /*PartitionIndex=*/1);

A new test pass, loop-split-test (opt -passes=loop-split-test with
-loop-split-points=...), drives the utility for testing. Adds lit tests
covering basic/multiple/four-partition splits, descending loops,
reductions, empty-leading partitions, optional guards, and the
per-partition value map.

[Driver][Hurd] Remove llvm_unreachable (#171077)

Remove the llvm_unreachable from getDynamicLinker(). The code path is
reachable. In the case of an unsupported architecture we're not worrying
about trying to actually determine the dynamic linker, and I don't think
it makes sense for the Driver to crash.

[ARM][MVE] Match canonical saturating negation patterns (#213085)

InstCombine pull request
https://github.com/llvm/llvm-project/pull/194519 canonicalized the
saturating negation idiom to
an llvm.ssub.sat operation. For the ARM backend we only recognized the
original
select and subtract pattern, causing vector absolute values to expand to
VQSUB
plus a compare and select instead of VQABS.

In this patch we teach the VQABS and VQNEG patterns to recognize this
ssub.sat
form.

[MLIR][Arith] Fix BitcastOp fold crashing on unhandled constant attributes (#212483)

`BitcastOp::fold` assumed any non-poison scalar operand attribute is a
`FloatAttr` or `IntegerAttr` and hard-casted it.
Constant attributes from other dialects, e.g. the `LLVM::UndefAttr`
produced by `llvm.mlir.undef`'s fold, hit the cast assertion.
This crashed SCCP on IR where `llvm.mlir.undef` feeds `arith.bitcast`.
Bail out on attributes and result types the fold does not handle.

[clang][AMDGPU] Clean-up handling of named barrier type (#207687)

- Allow the type in struct/classes in very limited circumstances. The
goal is to enable creating trivial wrappers around the named barrier
variable, but ensure we can't get into situations where things would get
awkward. Currently this means we only allow the named barrier in
RecordDecls with exactly 1 field, that have no base class, and are not
inherited.
- Use a `amdgpu_barrier` LangAS for this type that currently maps to the
local AS. This allows easy switching to the barrier AS in a future
patch.

[X86] Fix missing CFI after the Swift async context push (#202570)

The Swift async prologue pushes the context slot (pushq %r14 / $0) but
doesn't touch the CFA until the later .cfi_def_cfa_register %rbp. So the
CFA still describes the stack from before the push and stays stale all
the way through the leaq and the subq. If something unwinds in that
window (debugger, profiler, signal) it reads the wrong slot. Normal
execution is fine.

FIX: account for the push with .cfi_adjust_cfa_offset 8, then switch to
an %rbp-relative CFA (.cfi_def_cfa %rbp, 16) right after the leaq and
before the subq, so the rule is correct before rsp moves again.

Adds swift-async-cfi-prologue.ll (directives + .eh_frame rows, plus a
locals case for the subq) and updates swift-async.ll.

This addresses a test failure introduced in
4f6cf2c2072ccf5780ac30bf69ebf99b788dbd52.

`0x1122334455667788` is a non-canonical address on x86_64 (fails to
write to rsp) and gets its non-addressing bits masked off on read for
pc/lr/sp/fp on Darwin AArch64, so it doesn't round-trip on either. Zero
the top 20 bits to stay clear of both.

[mlir][bufferization] Handle arith.select-based deallocs in static memory planner (#209106)

The static memory planner currently skips any allocation that doesn't
have a direct `memref.dealloc` user. This is overly conservative, after
running `ownership-based-buffer-deallocation`, it's common to see
patterns like:

  `%2 = arith.select %c, %0, %1 : memref<1024xf32>`
  `memref.dealloc %2 : memref<1024xf32>`

where both `%0` and `%1` get skipped with `++numSkipNoDealloc` even
though their lifetimes are well-defined.

This patch teaches `collectCandidates` to follow `arith.select` chains
when looking for potential deallocs. We traverse the use-def graph
forward from each alloc, collecting any `memref.dealloc` ops reachable
through select results.

Since a single select-based dealloc can conditionally free one of
several allocs, we enforce a group constraint: all allocs that share a
dealloc via a select must either all go into the arena or all be
skipped. Without this, we could end up with a `memref.view` (an arena
slice) and a raw alloc being fed into the same select, making the
resulting dealloc invalid.

The group constraint is computed with a simple fixpoint iteration , if
any member of a group is ineligible, the whole group is dropped.

The lifetime indices (`timeStart`/`timeEnd`) in `buildAllocInfos` are
also fixed: the old code did one block scan per candidate (O(n×m)). This
replaces it with a single pass upfront using a `DenseMap`, and sets
`timeEnd` conservatively to the latest dealloc index across all
potential deallocs for an alloc.

Tests added for:
- Single alloc freed via a self-select dealloc
- Two allocs sharing one select-based dealloc (group constraint active)
- The two-select two-dealloc pattern from the design discussion

Reland [MachineLICM] Use `RegisterClassInfo::getRegPressureSetLimit` (#213584)

This relands #211715 which was reverted because of some failures
in experimental targets and one AMDGPU test `diverged-entry-basic.ll`.

Below is the original commit message.

----

This recommits #119826, which taught `MachineLICM` to use
`RegisterClassInfo` when computing register pressure limits so
reserved registers are accounted for (#118787).

The original change was reverted by eeac0ff because it increased
compile time by causing repeated `RegisterClassInfo` computations.

This PR is based on #210826, in which `MachineRegisterClassInfo`
analysis pass was added. `MachineRegisterClassInfo` is required
by `MachineLICM` now, but the intervening machine passes that do
not affect `RegisterClassInfo` now preserve it, so the analysis
is reused instead of recomputed.

Add FP min/max opcodes to the list of operations that can be folded into
write-masked instructions. This allows commuteSelect to recognize these
operations and invert the setcc condition to enable ISel to match fused
vminps/vmaxps {%k} patterns.

[Transforms][Utils] Preserve branch weights in LoopSplitUtils (#213626)

Carry the original latch's branch weights onto the clamped latch, and
mark the newly created partition-guard branches as having unknown
weights so profile-tracking passes are not misled.
