[AMDGPU] Classify generic-target features (#223179)
Classify features used by generic targets but absent from some covered
GPUs as AMDGPUGenericAnyFeature. This covers the gfx11 workarounds,
gfx12.5 register fixup and WMMA timing, and LDS size and bank count.
Derive the classified features directly from the SubtargetFeature
subclass and preserve their existing predicates. Keep RequiresCOV6
outside this policy because it is specific to generic targets and
absent from their covered GPUs.
Test the real target definitions, missing support for classified
features, and the existing all-member requirement for instruction
capabilities.

[NFC][AMDGPU] Add tests for fptrunc folded into V_MAD/FMA_MIX (#219723)
V_MAD/FMA_MIX{LO,HI} compute the multiply or multiply-add in f32, round
that to f32, and then convert the f32 result to the 16-bit destination.
That is the same pair of roundings the IR performs, so the instructions
are a bit-exact match for an fptrunc of an f32 multiply or multiply-add
and need no contract flag.
The tests pin that across gfx803, gfx900, gfx906, gfx90a and gfx1100
with +real-true16 for f16, and gfx1250 in both true16 modes for bf16.
Where a shape appears both unflagged and with contract, the two must
select the same instructions.

SwiftBuild passes -l to libtool, but I didn't catch it the first time
around because it's not in the xcspec. It is in the unit test though. Go
through all of the linker arguments and inputs and add the missing ones
supported by libtool.

-----------
[RISCV] Lower VECTOR_INTERLEAVE 4 and 8 with Zvzip via DAGCombiner (#223861)
This is the second take of #222432, and to some extent #222750
The full context of why moving to this implementation can be found here:
https://github.com/llvm/llvm-project/pull/222432#discussion_r3992576835
Basically, #222432 has the downside of generating redundant
vslideup/down, as no DAG combine would be run in between different
operation lowering. Although #222750 tried to address that problem, the
fact that it has to call RAUW in the middle of lowering might result in
unexpected result.
This iteration of approach use a DAG combine to break
vector_interleave4/8 into vector_interleave2 early in the ISel, so that
any redundant insert/extract_subvector or concat_vectors should be
cleaned up automatically. Though some redundant pairs of vslideup/down
still show up but they are relatively easy to clean up, which will be
done in the following patch.

[BOLT] Zero all stale bytes in reused file region (#222515)
`--use-old-text` reuses an input file region for new content. We have
only zeroed the padding that followed each newly written section in
#202375, which may leave stale bytes from input in front of the new
content. This could happen if the region is not on the new alignment
boundary, or when `--hot-functions-at-end` is used.
Replace the section name based forward scan with an interval coverage
over the region - collect the file extents of sections that contain
output bytes and then zero all the remaining holes.

[LLDB] Convert straightforward test launches to lldbutil (NFC) (#224404)
Replace the CreateTarget + breakpoint + LaunchSimple + stop-assert
boilerplate with the matching lldbutil.run_to_*_breakpoint helper at 35
call sites where the translation needs no extra arguments.
Besides being shorter, the helpers check that the breakpoint resolved to
at least one location and that the process stopped at that specific
breakpoint, which most of the original code did not do.
It also improves und unifies the error reporting when the launch fails.

[LLDB] Convert multi-threaded test launches to lldbutil (NFC) (#224415)
Replace the CreateTarget + breakpoint + LaunchSimple + stop-assert
boilerplate with the matching lldbutil.run_to_*_breakpoint helper at 7
call sites.
Besides being shorter, the helpers check that the breakpoint resolved to
at least one location and that the process stopped at that specific
breakpoint, which most of the original code did not do.
It also improves and unifies the error reporting when the launch fails.
Note for reviewers: These inferiors are multi-threaded and the original
code used get_stopped_thread(), which tolerates several threads stopping
at once. The helpers require exactly one by default, so every call here
passes only_one_thread=False to preserve the previous behavior. Without
it TestLLDBIterator fails with "Expected 1 thread to stop at breakpoint,
3 did" - but only under load, which makes this easy to miss when running
a single test.

Replace the CreateTarget + breakpoint + LaunchSimple + stop-assert
boilerplate with the matching lldbutil.run_to_*_breakpoint helper.
Besides being shorter, the helpers check that the breakpoint resolved to
at least one location and that the process stopped at that specific
breakpoint, which most of the original code did not do.
It also improves and unifies the error reporting when the launch fails.
Note for reviewers: These did not follow the common pattern and had to
be converted by hand, so they are worth a closer look than the earlier
batches:
- Five of them called get_threads_stopped_at_breakpoint() and indexed
the resulting list. The helper already returns the single stopped
thread, so the list, its length assertions and the [0] subscript all
collapse into it.
- TestSigtrampUnwind checked the stop state with an if/fail block rather
than an assertion.
- TestAddDsymDownload built its target from self.exe, which is just
getBuildArtifact("a.out"), so it needs no exe_name argument.
- TestThreadAPI looks up the thread inside a while loop, so only the
target creation and launch could be folded into the helper.

[compiler-rt] Fix the use of COMPILER_RT_BUILTINS_LIBRARY (#224681)
When `COMPILER_RT_BUILTINS_LIBRARY` is set and a path to the builtins
library is being provided, it is still not being used, causing an
error in the COMPILER_RT_TARGET_HAS_ATOMICS test:
```
ld.lld: error: undefined symbol: __aarch64_cas8_acq_rel
>>> referenced by src.cxx

ld.lld: error: undefined symbol: __aarch64_ldadd8_acq_rel

>>> referenced by src.cxx
>>> CMakeFiles/cmTC_7f91d.dir/src.cxx.o:(main)
clang++: error: linker command failed with exit code 1
```
Although it is visible in the
build/runtimes/runtimes-bins/CMakeFiles/CMakeConfigureLog.yaml log,
it is being ignored. This causes a cascade of subtle problems down the
line, including a faulty PGO instrumentation code being injected into
instrumented binaries, which causes race conditions whenever the
instrumented code is multi-threaded (a stub is being used instead of
the real atomics).

[CIR][EH] Implement codegen for dynamic exception specification (#224375)
This implements CIR generation for C++ functions with dynamic exception
specifications. The exception filter is implemented as a cir.try
operation that wraps the entire function body. CFG flattening and EH ABI
lowerting were implemented in previous changes, so they are already in
place.
This also adds an NYI diagnostic for functions marked `noexcept`. That
will be implemented in a follow-up change, but the new diagnostic forced
updates to a few tests that were using that form.

[CIR] Add object offset calculation for basic AA (#219047)
This adds code to compute the offset of a pointer into a base object
when the base object is computed by CIR's basic alias analysis. The
offset will be used in a future change to determine partial alias, but
at this point the analysis still reports MayAlias for objects with
different offsets.

[mlir][VectorToXeGPU] Lower out-of-bounds 1-D transfers (#220490)
A vector.transfer_read / vector.transfer_write whose vector is 1-D and
whose access is out of bounds was not lowered.
This PR now builds a real in-bounds mask instead of handing
xegpu.load/xegpu.store an all-ones one. An element is in bounds when its
index is still inside the memref dimension it reads, i.e. i < dim(d) -
indices[d], and dimensions the transfer already declares in-bounds are
left alone. Since masked-off lanes of an xegpu.load hold unspecified
values rather than zeros, a read adds an arith.select to fill them with
the transfer's padding.
It also lowers a transfer_read of a single-element vector (any rank) to
a scalar xegpu.load, when that vector is only ever extracted to a
scalar. The load takes a scalar offset and a scalar mask, and the mask
is what keeps an out-of-bounds transfer from touching memory; because a
masked-off load is unspecified, the padding is applied with an
arith.select, as the scattered path already does. This avoids
special-casing single-element vectors in layout propagation: a scalar
consumer requests no layout, so the one-lane xegpu.load would otherwise
be left without one.

[llvm-jitlink] Rework out-of-process launch/connect options (#224632)
Replace -oop-executor and -oop-executor-connect, which were mutually
exclusive and each parsed their own ad hoc connection syntax, with two
orthogonal options built on the shared ConnectionSpec parser:
-oop-launch [<path>] Launch an out-of-process executor (default:
llvm-jitlink-executor).
-oop-connect <spec> How to connect to the executor, whether or not
it was launched by llvm-jitlink.
Either may be used alone (matching the old -oop-executor and
-oop-executor-connect behavior) or combined, e.g. to have llvm-jitlink
bind and listen while the executor it launches dials back in:
llvm-jitlink -oop-launch -oop-connect=tcp:listen=127.0.0.1:0 a.o
Both llvm-jitlink and llvm-jitlink-executor now parse connection
descriptors with ConnectionSpec (<transport>[:<action>]=<descriptor>)
instead of bespoke per-side parsing, and support the same three specs in
both directions: fd=<sockfd>, tcp:connect=<host>:<port>, and
tcp:listen=<host>:<port>.
For the reverse-connect case (llvm-jitlink listens, the executor
connects back), llvm-jitlink binds and resolves the listening port
before launching the executor, so it can hand the executor the concrete
port -- including when an OS-assigned ephemeral port ("0") was
requested. The host in a tcp:listen spec is now also honored as the bind
address (previously always wildcard-bound); an empty host still requests
a wildcard bind.
These changes will be used to support interaction with, and testing of,
the ORC runtime's new OGRE (ORC General-purpose Runtime Environment)
executor.

[SanbdoxIR][SandboxVec] AuxPassArgs for auxiliary pass arguments (#224450)
This patch implements helper classes for handling the pass auxiliary
arguments. These classes handle the parsing of the auxiliary argument
string such that the passes themselves won't have to deal with it.
We currently only support boolean arguments that are false by default.
If an argument shows up in the string then it is set to true.
Example:
```
AuxPassArgsRegistry ArgsRegistry; // The "parent" of the arguments
AuxPassArg Arg1 = ArgsRegistry.createArg("arg1");
AuxPassArg Arg2 = ArgsRegistry.createArg("arg2");
...
ArgsRegistry.parse("arg1"); // From this point on (bool)Arg1 evaluates to true.
```
This patch is also removing the `cl::opt<std::string> CollectSeeds` for
the SeedCollection and replaces it with AuxPassArgs. So we are now
specifying the seeds in the pass pipeline like:
```
-sbvec-passes="seed-collection(loads,stores,enable-diff-types)"
```

[TargetLowering][COFF] Allow GlobalAlias in lowerRelativeReference (#220674)
In commit 2b321e2f293a (#203171), splitAndWriteThinLTOBitcode was
updated to create a GlobalAlias with external linkage for promoted
internal globals instead of renaming them directly.
When generating COFF object files on Windows (such as MSVC RTTI
CompleteObjectLocator structures), relative references against
@__ImageBase (e.g. sub (ptrtoint @alias to i64), (ptrtoint @__ImageBase
to i64))
are lowered to IMAGE_REL_AMD64_ADDR32NB (VK_COFF_IMGREL32) relocations
in TargetLoweringObjectFileCOFF::lowerRelativeReference.
Previously, lowerRelativeReference checked `!isa<GlobalObject>(LHS)`,
which rejected GlobalAlias instances. As a result,
lowerRelativeReference returned nullptr, and AsmPrinter fell back to
emitting a raw MC subtraction expression. This caused
WinCOFFObjectWriter
to fail with:
\"error: symbol '__ImageBase' can not be undefined in a subtraction
expression\"
because @__ImageBase is an undefined external symbol resolved at link
time.
Fix this by checking !LHS->getAliaseeObject() instead of
`!isa<GlobalObject>(LHS)`, allowing GlobalAliases whose underlying
aliasee is a GlobalObject to be lowered to VK_COFF_IMGREL32.

[LowerTypeTests] Reorder CFI jump table entries based on hotness (#221046)
Order CFI jump table entries by function hotness. We use `cfi.functions`
metadata in ThinLTO, or `BlockFrequencyInfo` / function entry counts in
full LTO.
We want the hottest function to be optimized by the last entry thing for
SHT_LLVM_CFI_JUMP_TABLE. The linker deletes the final branch in the jump
table and moves the table directly before that target function so it
falls through.
This also ensures the jump table lands in a hot section (.text.hot)
instead of a cold section (.text.unlikely). Type contiguity is
preserved.
This PR reliably improves the performance of our server binary by 0.2%,
and some smaller binaries up to 5%.

[Option] Emit the Info table from TableGen. NFC (#224508)
Each tool expands OPTION into an Info array and passes it with up to
five side tables to GenericOptTable or PrecomputedOptTable, so a new
side table touches every tool.
Emit the Info table from TableGen with numeric group and alias IDs and
bundle all tables into an OptTable::Tables aggregate under one
OPTTABLE_CODE block, so a tool just constructs OptTable(OptionTables).
Every table now uses the precomputed prefix union, which removes
GenericOptTable and PrecomputedOptTable.

[llvm][timing] Reset recycled timer with different names. (#218492)
Legacy pass-manager timers are keyed by the pass instance pointer and
the map entry outlives the pass, so a pass allocated at a recycled
address inherits the previous pass's timer and reports its time under
that pass's name. When a recycled instance which has different name can
end up having leftover name comes from whichever target ran before.
Re-create the timer when the name no longer matches.

[LFI][AArch64] Do not flush deferred LR guards on temporary labels (#224776)
In function epilogues with unwinding enabled, DWARF CFI directives
between restoring x30 and autiasp trigger
MCObjectStreamer::emitCFILabel, which emits temporary labels. onLabel
assumed all labels were branch targets and flushed DeferredLRGuard,
emitting `add x30, x27, w30, uxtw` before autiasp. Because w30
zero-extends, this stripped the PAC signature from x30 and caused PAC
exceptions on hardware with FEAT_FPAC.
Fix it by not flushing the deferred LR guard on temporary symbols in
onLabel. Also, update AArch64InstrInfo::getLFIInstSizeInBytes to return
8 for RET to fix the size assertion failure in +assertions builds, which
occurs because RET did not account for the deferred LR guard that can
precede the return instruction.

[lldb] Bound DataExtractor::PeekCStr to the data it reads from (#224452)
PeekCStr only validated the first byte without checking for a terminator.
Every caller then treated the result as a C string, so an unterminated
string table let strlen run past the mapping, causing a crash or
security bug.
Return an optional StringRef, produced only when the terminator lies
within the data. The length comes along with it, so callers no longer
rescan, and an absent string stays distinct from an empty one.
ValueObject was the only caller that wanted an unterminated buffer. It
scans fixed size chunks of inferior memory, so it now asks for bytes with
PeekData and bounds its own scan.

Derive the prefix union from the prefix table in the constructor and

carries all five. Move them to a deduplicated InfoExtra side table
reached by a 16-bit offset; row 0 serves options that set none. Narrow
Visibility to 16 bits; clang uses seven.
clang's table shrinks from 155 KB to 93 KB plus 4 KB of extras.

- Remove the warning message "warning: MIPS-I support is experimental" from

expect diagnostic output on stderr.
- Remove experimental / highly experimental from a few MIPS processors.
MIPS I is on track and the rest I wouldn't consider experimental anymore.

A StringTable is just a StringRef. Hold it by value and build it from
the storage array in optionTables(), so the generated OptionStrTable
object (16 bytes of .data.rel.ro and a relocation per table) is
unreferenced and discarded, and string lookups skip a load.

[SelectionDAG] Allow PARTIAL_REDUCE_SUMLA in getPartialReduceMLS (#220886)
foldPartialReduceMLAMulOp turns
partial_reduce_*mla(acc, neg(mul(sext(a), zext(b))), splat(1))
into a PARTIAL_REDUCE_SUMLA node and, because of the negation, builds it
through SelectionDAG::getPartialReduceMLS. That helper only accepted
UMLA
and SMLA, so the mixed-sign case hit its "Unexpected opcode" assertion
whenever the target marks SUMLA as legal or custom for the transformed
types. The loop vectorizer produces exactly this shape for a reduction
chain that mixes adds and subs, e.g.
acc += (int)s8_a[i] * (int)u8_b[i];
acc -= (int)s8_c[i] * (int)u8_d[i];
so this crashed at -O2 in builds with assertions enabled on AArch64 with
+dotprod, and since #205373 also on X86 with AVX512-VNNI (release builds
already generated correct code).
The identity used by getPartialReduceMLS,
partial_reduce_mls acc, lhs, rhs <=> -(partial_reduce_mla -acc, lhs,
rhs)
does not depend on the signedness of the inputs, so SUMLA can simply be
accepted. Add AArch64 tests for the SVE and NEON usdot forms, and for
the two-udot expansion used without +i8mm.

`populateRegionBranchOpInterfaceCanonicalizationPatterns` on downstream
control flow op with it resulted in broken IR. Update the segments sizes
if present.
Also fix LLVM dialect `CallOp` and `InvokeOp` `getArgOperandsMutable`
which were dropping segment sizes and a parser bug uncovered by the
tests.
Code was vibed and then edited, tests were vibed and not particularly
edited.

flattens a diamond merging a v4i16 but leaves the equivalent v4i32

We can create a conditional select similarly to how vector selects are
lowered in the backend by spreading the condition into an all-1's /
all-0's mask and use a bit select.

[X86] Prevent legalization cycles in lane-permute shuffle lowering (#224265)
When a cross-lane shuffle reproduces the original mask, trying a finer
sublane size can produce a decomposition that legalization transforms
back into the original shuffle. This causes legalization to cycle
indefinitely.
Stop trying finer sublane sizes when this condition is detected, and add
a regression test for the shuffle that previously caused `llc` to hang.

[analyzer] Confidently inline final methods (#224070)
When the analyzer sees a virtual method call, it usually splits two
execution paths: one where the method is inlined, and one where it is
evaluated conservatively (i.e. invalidates stuff and returns a conjured
symbol) to represent the possibility that an overriding method is called
from a more derived class.
This commit disables this logic in the case when the method
corresponding to the (static or known dynamic) type of the object is
`final` (or the type of the object is `final`), because in these cases
we can definitely know that it is the method that is actually called.
Fixes #222960.

We can directly use SubOverflow, avoiding the extra multiply operation
and potential overflow.
This improves results in some edge cases. I do not think it will trigger
in practice, but it is also simpler and cheaper.

[libc][math] Add code size optimized float-only options for exp*f funtions. (#224735)
- Add float-only implementations for expf, exp2f, and exp10f optimized
for code-size.
- Reorganize function selections:
- `src/__support/math/func.h` - select implementation
- `src/__support/math/func_<type>_eval.h` - implementation with `<type>`
as intermediate computational type.
- keep different `<type>-eval` in `type_eval` namespace, so that all
options are available to be tested.
- Update smoke, unit, exhaustive tests to test all variants.

[libc][math] Make pow function correctly rounded for all rounding modes. (#222827)
Fix overflow issues reported by Paul Zimmermann.
Algorithm overview:
Evaluate mainly as:
```
x^y = 2^(y * log2(x))
```
- Fast path:
- Compute `log2(x) = e_x + log2(m_x)` in double-double precision.
- Scale `y * log2(x)` and evaluate `2^(y * log2(x)) = 2^hi * 2^mid *
2^lo`
using a 64-entry lookup table for `2^mid` and a degree-5 polynomial
evaluated with Estrin's scheme for `2^lo`.
- Perform Ziv's rounding test.
- 128-bit accurate path (pow_accurate_128.h):
- If the fast path Ziv's test fails, recompute `log2` and `exp2` using
fixed-point arithmetic with Frac128 and Frac64.
- Evaluate degree-15 polynomial for `log2` and degree-11 polynomial for
exp2 with minimax coefficients generated by Sollya.
- Use Horner scheme in 2 steps: higher degree terms are evaluated
with 64-bit precision before combining into 128-bit precision.
- Detect exact and midpoint rounding boundaries using algorithm
described in
Lauter, C. and Lefevre, V., "Rounding Boundary Cases for Values of the
Exponential and Power Functions," IEEE Trans. Comput. 58(8):1063-1074.
- 256-bit accurate path (pow_accurate_256.h):
- If the 128-bit result fails the Ziv's test, recompute using 256-bit
fixed-point
arithmetic with Frac256.
- Evaluate degree-31 polynomial for `log2` and degree-21 polynomial for
`exp2` using Horner scheme in 3 steps (64-bit -> 128-bit -> 256-bit).
- Share the 64-entry table `EXP2_MID_FRAC256` with the 128-bit path.
- Add `Frac256` class in `libc/src/__support/frac256.h` for unsigned
256-bit
fixed-point arithmetic.

Add the reentrant group database lookup entrypoints getgrnam_r and

grp_utils.
Each lookup opens a ScopedFlatFileDatabase<struct group> stream so that
reentrant lookups do not disturb an in-progress getgrent iteration.
Track group_file_path alongside the iteration database so scoped streams
opened by reentrant lookups honour test path overrides.
* Add getgrnam_r and getgrgid_r entrypoints
* Add find_by_name and find_by_gid lookup helpers in grp_utils
* Define getgrnam_r and getgrgid_r in include/grp.yaml
* Add hermetic unit tests for getgrnam_r and getgrgid_r

[CodeGen] Reject undef tied use sharing a virtual register with another read (#222832)
A virtual use operand, tied to a def of a different register, sharing
the register with another read, carries obligation that is hard to
follow by passes. For example, twoaddressinstruction would use different
physical registers, breaking the expectation of the `IsUndef` flag:
```
define void @f() {
%y = freeze i32 undef
%m = mul i32 %y, %y
call void asm sideeffect "# use $0", "{cx}"(i32 %m)
ret void
}
%2 = IMUL32rr undef %1(tied-def 0), undef %1 ; before twoaddressinstruction
%2 = IMUL32rr undef %2(tied-def 0), undef %1 ; after
imull %eax, %ecx ; different regs
```
RegAllocFast had the same issue until #222249. Let's just reject the
shape to retire the obligation. `%0 = XOR undef %0, undef %0` stays
legal, since rewriting that tie changes nothing.
ProcessImplicitDefs and DetectDeadLanes stop producing the rejected
form: such reads keep their IMPLICIT_DEF. Physical registers are
unaffected, so post-RA expansions like Expand2AddrUndef keep
`$eax = XOR32rr undef $eax, undef $eax`.

ISD::SCALAR_TO_VECTOR documents its upper elements (1..N-1) as poison,
not undef. Update both helpers to use includesPoison(Kind) instead of
includesUndef(Kind) when those elements are demanded, so PoisonOnly
queries correctly report that the upper elements can create poison and
are not guaranteed to be poison-free.

possible, so whilst `sincos` itself is not (yet) a standard library
interface, it has to be handled as well. This extends the set of covered
intrinsics to include it.

[clang][bytecode] Notify bytecode interpreter after deserializing constant global declarations (#198062)
The problem looks something like this:
```c++
extern const int m;
constexpr int getm() { return m; }
const int m = 12;
static_assert(getm() == 12);
```
The generated bytecode for `getm()` references a global variable stored
in `interp::Program`. This variable is uninitialized when the bytecode
is generated, but since it's extern, that's not diagnosed (because it
might be initialized later).
When we parse the redeclaration of `m` on line 4, we evaluate its
initializer via `Expr::EvaluateAsInitializer`, which makes the bytecode
interpreter aware that `m` has been redeclared. It will create a new
global for the new declaration and make the previous global point to the
new one. When the bytecode is then evaluated in the `static_assert`,
there is no problem.
However, when the redeclaration isn't part of the TU but gets
de-serialized via a module (which is the case in
`test/Modules/redecl-add-after-load.cpp`), we don't call
`EvaluateAsInitializer`, we don't even necessarily de-serialize the
initializer expression at all. So the bytecode interpreter doesn't know
about the new declaration and the static_assert ultimately fails because
`m` is not initialized.
Marking this as a draft PR since I'm not sure this is the best way to do
this and if bytecode-specific things in other parts of the code base are
tolerated.

[SCEV] Increase RewriteMap default size (NFC). (#224864)
The old automatic default of 4 inline buckets meant that in practice we
were frequently hitting the grow path to 64 buckets, causing unnecessary
memory traffic.
SCEVRewriteVisitor is used each time loop guards are applied and the new
default improves compile-time slightly for SCEV-heavy workloads. Geomean
improves by -0.03%, but mafft and lencod see bigger wins:
https://llvm-compile-time-tracker.com/compare.php?from=7c55ad084c8b1503cafa42c60d88bff65919c9fa&to=c1f14fba38c4cd7b282709d8bd9481d28642b2c6&stat=instructions:u
It mostly makes applying loop guards cheaper, making it easier to use in
more places in the future.

[X86][APX] Fix EFLAGS reuse across cycles (#223613)
optimizeCompareInstr's multi-predecessor NF reuse (added in
ab39c491430e) did not scan the below-CmpInstr region of CmpMBB when
CmpMBB was on a CFG cycle: that region is on the back-edge path but is
scanned by neither the caller nor the helper's predecessor walk. A
non-NF-convertible EFLAGS clobber there (e.g. an unrelated CMP feeding a
JCC, as in the reproducer below with VUCOMISS/CTEST/COPY-\$eflags) still
let the helper delete the redundant compare and mark \$eflags live-in on
CmpMBB. That broke the reused EFLAGS on iteration 2+ and tripped
X86FlagsCopyLowering's SuccMBB == TestMBB self-loop check with a fatal
report_fatal_error when a preexisting COPY \$eflags save/restore sat in
the cycle.
Reproducer: https://godbolt.org/z/s58j5zxqd
Detect CmpMBB on a cycle via a forward-reachability BFS on its
successors and, when so, scan from just after CmpInstr to the block's
end: bail on any non-NF-convertible EFLAGS clobber, stage NF-convertible
ones. The rest of the helper is unchanged.
Tests exercise the bail paths (selfloop_shadow_below,
twoblock_cycle_shadow_below, threeblock_cycle_shadow_below,
selfloop_nfconvertible_below_cap), the positive stage-and-succeed path
(selfloop_nfconvertible_below), and the CmpMBB-not-on-cycle skip path
(multipred_above_cmpmbb).

This was an oversight in #223396 due to incorrect documentation for

[libc++] Add a compact, bounded iterator (#208271)
- By taking advantage of unused alignment bits for a pointer of type `T`
and the static capacity known at compile time, we can make a compact
bounded iterator who's size == `sizeof(T*)` by stuffing a counter inside
those bits.
- This new iterator type is `static_packed_bounded_iterator<class _Ptr, size_t _RangeCapacity>` and is only valid if:
- `_Ptr` is a pointer
- `_RangeCapacity` is <= `(1 << (bit_width(alignof(T)) - 1)) - 1`. The
extra -1 is required, because we need to represent the end position past
the last element.

This also implicitly implements `str(SBStringList)`.

32-bit unsigned arithmetic and can wrap, e.g., with
-loop-interchange-max-mem-instr-ratio=2147483648 and 20 instructions the
left product wraps to 0 and the pass rejects an otherwise eligible nest.
Compute both products in uint64_t instead, which cannot overflow as all
three operands are 32 bits wide.

[NFC][AMDGPU] Add tests for fpround of fadd and fsub feeding the mix instructions (#224909)
The f32 mix patterns already fold fadd and fsub into v_mad_mix_f32 and
v_fma_mix_f32, but the f16 and bf16 forms only fold fmul, so a half or
bfloat result still pays for a separate convert.
Also cover the denormal modes an f16 result depends on and an f16
source feeding an f16 or bf16 mix. The existing mad-mix-lo and
mad-mix-hi functions now flush denormals for every type rather than
for f32 alone.

[AMDGPU] Add partial unroll threshold function attribute (#223291)
This change adds an `amdgpu-partial-unroll-threshold` function attribute
for controlling
`TargetTransformInfo::UnrollingPreferences::PartialThreshold` on a
per-function basis.
The existing `amdgpu-unroll-threshold` function attribute initializes
`UP.Threshold`, which is used for decisions about full
unrolling. However, there is currently no corresponding AMDGPU function
attribute for configuring `UP.PartialThreshold`
independently. As a result, clients of the AMDGPU backend cannot provide
an independent per-function cost threshold for partial and runtime
unrolling.
When present, the new attribute sets the base value of
`UP.PartialThreshold` for loops in that function. This allows the cost
threshold for partial and runtime unrolling to be configured
independently of the threshold used for full unrolling. Functions that
do not use the new attribute retain their existing behavior.
The AMDGPU function attribute documentation is updated accordingly. A
regression test sets `amdgpu-unroll-threshold` to zero and
`amdgpu-partial-unroll-threshold` to 30, then verifies that the loop is
partially unrolled by a factor of two without being fully unrolled.

Clang did not handle loongarch32-\*-none-elf and loongarch64-\*-none-elf
in the
bare-metal toolchain, so these targets fell back to the generic ELF
toolchain,
which links by running gcc. Any -fuse-ld or --ld-path option is
forwarded to
gcc, and linking fails when there is no gcc. On a host whose gcc does
not target
LoongArch, which is the usual case when cross compiling, gcc drives the
linker
for the host, and the link fails with errors such as "a.o is
incompatible with
elf_x86_64". The generic ELF toolchain also searches /usr/local/include
and
/usr/include of the host.
The other bare-metal targets, Arm, AArch64, RISC-V, PowerPC, and x86
since
25f0d08bafa4, use the bare-metal toolchain, which runs the selected
linker
directly and does not search host include directories.
Handle LoongArch there as well. As the GNU toolchain does for LoongArch,
and the
bare-metal toolchain already does for RISC-V, pass -X to the linker, and
--no-relax with -mno-relax.

[C++20] [Modules] Profiling non dependent noexcept expression by pointer (#224528)
Another approach to solve
https://github.com/llvm/llvm-project/issues/191361 and
https://github.com/llvm/llvm-project/issues/224180 than
https://github.com/llvm/llvm-project/pull/222148
I want to avoid competing PR but I do feel the original one's approach
seems too workaround. And I want to emphasize that, in my experience,
finding the root cause is much more harder than find the solution to me.
Many thanks to @ispeters
For the approach itself, I described them in the comments of the PR.
Note that the real problem is we were profiling something is not
completely deserialized, so that even if it is not crash, the logic is
not correct.

[compiler-rt] Use integers for __gnu_h2f_ieee and __gnu_f2h_ieee (#220167)
In libgcc, these conversion routines use integers in the signature. In
practice compiler-rt's definition has worked because the AAPCS calling
convention passes and returns floats the same as the same-sized integer,
but this may not be the case on all platforms. Thus, update the
signatures to match GCC.
This new version calls the inlined functions directly., changing the
generated code from:
00000000 <__extendhfsf2>:
0: ee100a10 vmov r0, s0
4: e1a01000 mov r1, r0
<snip>

74: ebfffffe bl 0 <__extendhfsf2>
78: ee100a10 vmov r0, s0

00000000 <__extendhfsf2>:

<snip>
60: e1800001 orr r0, r0, r1
64: ee000a10 vmov s0, r0

0000006c <__gnu_h2f_ieee>:
6c: e1a01000 mov r1, r0
70: e7e42550 ubfx r2, r0, #10, #5
<snip>
c8: e1800001 orr r0, r0, r1
cc: e12fff1e bx lr
This avoids an unnecessary indirection and register shuffle when calling
`__gnu_h2f_ieee`. It does mean the code is effectively duplicated
however, since any given target will only ever use `__gnu_h2f_ieee` or
`__extendhfsf2` but never mix them, this is an improvement in the final
binary. (The same logic applies to `__gnu_f2h_ieee` and `__truncsfhf2`.)

[LoongArch] Introduce PseudoAddUpperImm to deduplicate stack-frame base address materialization (#217250)
This is largely inspired by
https://github.com/llvm/llvm-project/pull/211748, except some LoongArch
specific changes, which includes merge 12-bit signed immediate into
`ld/st` instructions while materializing the frame index first to
generate a `lu12i.w + add` combo if we could, instead of a `lu12i.w +
ori + add`. So that we could use a `PseudoAddUpperImm` to replace them
for `MachineLateInstrsCleanup` to deduplicate them later on.
This patch improves SPEC CPU2026 `709.cactus_r` performance by 27% (from
1.64 to 2.09).
**edit:** After replacing some `ld/st` with `ldptr/stptr` as long as
their address offset could not fit in 12-bit imm but could fit in 14-bit
one, the `709.cactus_r` slightly improved from **2.09** to **2.16**,
however this is done by `-O3 -mlasx`, with `-O3 -mlsx`, the score
remains at **2.31**, which shows its bottleneck is no longer on address
materialization.

in the case of promotion of large const variables) are not required to
respect this ABI alignment. To avoid having to go through GOT to load an
unaligned addressed, we should try to raise the alignment of such
globals in the backend. This is done through a new SystemZ-specific
module pass.

[clangd] Extend FeatureModule hooks (#221054)
Feature modules may need to participate at points in AST construction
that `beforeExecute()` and `sawDiagnostic()` cannot represent.
This PR adds:
- `beforePPCallbacks()` for installing preprocessing observers before
clangd starts collecting include and macro events.
- `afterExecute()` for work that needs a completed AST after token
collection and traversal-scope restriction.
- `finalizeDiagnostic()` for transformations that need the complete
diagnostic, including its notes and fixes.
For example, clang-tidy needs to register preprocessing callbacks before
preamble events are replayed, run AST matchers after clangd restricts
the traversal scope, and process diagnostics after their notes and fixes
are attached.
These changes prepare moving the clang-tidy implementation into a
FeatureModule.

[mlir][LLVMIR] Fix loop follow-up metadata import and export (#223376)
## Problem
MLIR currently exports loop follow-up metadata by wrapping its
properties in an additional self-referencing loop ID:
```llvm
!1 = !{!"llvm.loop.unroll.followup_unrolled", !2}
!2 = distinct !{!2, !3}
!3 = !{!"llvm.loop.mustprogress"}
```
LLVM expects the properties directly after the follow-up name:
```llvm
!1 = !{!"llvm.loop.unroll.followup_unrolled", !3}
!3 = !{!"llvm.loop.mustprogress"}
```
`makeFollowupLoopID` copies the follow-up operands without unwrapping a
nested loop ID. Consequently, properties such as
`llvm.loop.mustprogress` inside the extra wrapper are not recognized as
properties of the resulting loop.
## Changes
- Export follow-up properties directly, excluding the temporary loop
ID's self-reference.
- Update import to read direct property lists.
- Preserve explicitly empty follow-ups, multiple properties, nested
follow-ups, and debug locations.
- Diagnose malformed follow-up metadata and detect cycles to prevent
infinite recursion.
An explicitly empty follow-up is different from an absent follow-up: it
specifies an empty configuration instead of leaving the transformation
to use its default follow-up attributes. Import therefore preserves it
as a non-null, empty `LoopAnnotationAttr`.
This patch corrects MLIR's representation of existing LLVM follow-up
metadata. It does not change LLVM's transformation policies or introduce
automatic attribute inheritance.
## Testing
Built `mlir-translate`, `FileCheck`, `count`, and `not` on Linux using a
Release build with assertions enabled.
All three targeted regression tests passed:
- `mlir/test/Target/LLVMIR/loop-metadata.mlir`
- `mlir/test/Target/LLVMIR/Import/metadata-loop.ll`
- `mlir/test/Target/LLVMIR/Import/import-failure.ll`
`git diff --check` also passed. The full MLIR test suite was not run.

[DAG] Optimize masked store of constant lane mask to standard store (#224255)
A masked store with a constant mask enabling the first n lanes can be
lowered to a standard store of size n.
For example a masked store with masks `<1, 1, 0, 0>` or a scalable store
with mask `llvm.get.active.lane.mask.v4i1.i32(i32 0, i32 2)`
This is a recommit of #223665 with a legal type check to protect against
v1f64 stores on X86 with +avx512.

[Support] Accept only true, false, 1 and 0 for cl::opt<bool> (#224975)
For these internal developer options, accepting `-flag=` (empty
value)/`-flag=True`/`-flag=FALSE` is a weird quirk. To the best of my
knowledge, they are nearly never used. Drop the spellings. In the
future, we will migrate to `-flag`/`-no-flag` (or their double-dash
form).

LoongArch: Simplify handling of call pseudo operands when expanding. (#224824)
copyImplicitOperands isn't really intended for the call instruction case
where there are also variadic operands. This avoids duplicating the R1
implicit-def operand when expanding calls. This avoids having mixed dead
and not dead flags on the same register, which will fail a future
verifier check.

by instruction selection. Declare tracksRegLiveness: true and noVRegs:
false, and add -verify-machineinstrs to the RUN lines.

[lldb] [NFC] Fix unused variable warning in MemoryCache::InsertPartialLine (#224973)
A Release build (assertions disabled) warns:
```
lldb/source/Target/Memory.cpp:144:18: warning: unused variable 'line_size' [-Wunused-variable]
144 | const uint32_t line_size = m_L2_cache.GetLineByteSize();
| ^~~~~~~~~
```
`line_size` was read only inside the `assert` that checks a partial-line
insert does not cross a cache line boundary. `assert` expands to nothing
when `NDEBUG` is defined, so the variable becomes unused in that
configuration.
`llvm/docs/CodingStandards.md` covers this shape directly:
```
In the first case, the call to `V.size()` is only useful for the assert,
and we don't want it executed when assertions are disabled. Code like
this should move the call into the assert itself.
```
so call `GetLineByteSize()` in the assert and drop the local.
Verified by building `lldb/source/Target/Memory.cpp` with
`-DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=OFF`: the warning
above reproduces before this change and is gone after it, with a clean
rebuild of the same object file.

[VPlan] Fix VPInstruction::AnyOf combine undoing freeze (#223640)
There is an any-of combine for unrolled VPlans which does:
any-of (fcmp uno A, A), (fcmp uno B, B), ...-> any-of (fcmp uno A, B)
However any-of implicitly freezes each individual operand and this means
we go from `freeze (fcmp uno A, A)` to `freeze (fcmp uno A, B)` which
isn't sound: https://alive2.llvm.org/ce/z/UdQM7C
This causes miscompiles today with early exit loops that are unrolled,
see the attached test case in single-early-exit-anyof-fold.ll.
This fixes it by explicitly modelling the freeze in VPlan. There are
three places where we use AnyOf:
1) early exit loops: the freeze needs to be applied per-lane, so apply
it as `(any-of (freeze (combined-conds-to-exit)))`
2) handleMaxMinNumReductions: we need to freeze the operands to the
min/max reductions earlier since they have multiple uses introduced and
we don't check the values aren't undef
3) handleFindLastReductions: we need to freeze Cond itself since it's
got multiple uses, but I plan on fixing this in a separate PR
Fable 5.1 was used to help generate the tests

[RISCV] Fold vmnot.m of an integer compare into the compare (#222553)
Fold a mask NOT of an integer vector compare into the compare by
inverting
the condition code, so `vmsne.vi` + `vmnot.m` becomes `vmseq.vi`:
(vmxor_vl (setcc_vl a, b, cc), vmset_vl) -> (setcc_vl a, b, !cc)
Only `SETCC_VL` with integer operands, one use and an undef passthru is
handled. The NOT also flips the masked-off lanes, which the inverted compare
would copy unchanged from the passthru, so the passthru must be undef.
The mask can be anything. FP compares are excluded since the inverse of an
ordered compare is unordered.

[mlir] Fix ArmSME ABI stub exports (#224629)
Previously, the `MLIR_ARMSMEABISTUBS_EXPORTED` macro would expand to
`__declspec(dllimport)` when building LLVM as a dylib on Windows. This
would cause a build failure since it is an incorrect annotation on a
function definition.
The intent here is to always export the symbol, so these changes use the
`LLVM_ALWAYS_EXPORT` macro, which properly expands to the right
attribute depending on the compiler / platform.
The effort to build LLVM as a dylib is tracked in #109483.

[MLIR][OpenMP] Support for dispatch construct with clauses nocontext & novariants (#215877)
Support for dispatch construct with clauses nocontext & novariants clauses in MLIR
This patch adds the omp.dispatch operation to the OpenMP dialect, along
with the nocontext and novariants clauses, the verifier, and LLVM IR
translation. It is limited to the MLIR layer. Flang lowering follows in
later patches.
Part 1 of 3 of the !$omp dispatch support.
This is derived from
[203320](https://github.com/llvm/llvm-project/pull/203320) (split into 3
parts).
This also Fixes[
#203317](https://github.com/llvm/llvm-project/issues/203317)

[llvm-dwarfdump][LineCov] Add --variable-coverage-maybe-undefined option (#220855)
This patch adds a `--variable-coverage-maybe-undefined` flag to
llvm-dwarfdump as part of the recently implemented feature that measures
DWARF coverage of local variables in terms of source lines. This causes
the IR-level analysis to consider variables live if they are defined on
any path, and therefore include lines where the variable may be
undefined. By default, variables must be defined on all paths to be
counted.
Additionally, it includes fixes for a few issues found by @SLTozer and
myself after merging the previous patches:
- Variables not present in the DWARF information that appear in the
baseline are now included in the output.
- The assertion that there are no `undef`/`poison` variable locations in
the IR has been removed, as in some circumstances it is possible to have
a `#dbg_declare(poison)` at `-O0`.
- A small error where entries were inserted into the file name map while
iterating through it has been fixed.

[MLIR][NFC] Drop sentinel leftovers from DenseMapInfo<Remark> (#224612)
`DenseMap` no longer uses sentinel keys, and the `getEmptyKey` and
`getTombstoneKey` members of `DenseMapInfo<Remark>` were removed in
#200633 and #201991. Two leftovers stayed behind, the `"<EMPTY_KEY>"`
comparison at the top of `isEqual` and the static dummy `MLIRContext`
that used to back the sentinel remarks.
The comparison is also wrong. A remark literally named `<EMPTY_KEY>`
compares unequal to any other remark, including one with a matching
hash, which breaks the hash and equality contract. This change removes
both leftovers and adds a comment saying what the specialization
compares, which is location, remark name, combined category name and
kind.
No behaviour change for any remark with a normal name. Existing Remark
unit tests and `mlir/test/Pass/remark-final.mlir` cover the
specialization through `RemarkEmittingPolicyFinal`.

[Mips] Introduce ABI-specific register names and accessors (#224284)
To accommodate the P32/P64 ABIs, we need to separate machine registers
from ABI register names and calling-convention roles. The existing
register IDs use OABI names, even when another ABI assigns a different
role to the same physical register.
As a first step, describe OABI, NABI and PABI names with
RegAltNameIndices. Extend TableGen's AsmMatcherEmitter with the opt-in
ShouldEmitMatchRegisterAltNameWithIndex flag, which generates
MatchRegisterAltName(StringRef, unsigned AltIdx). It matches only names
associated with the selected index, allowing the same spelling to
identify different registers across ABIs.
Use the indexed matcher in shared MIPS register lookup for the assembler
and named-register lowering, retaining compatibility aliases and
diagnostics for deprecated spellings.
Add ABI accessors for argument, temporary, saved and return registers,
backed by shared register lists, and use them in lowering code. Keep the
existing register IDs and assembly/MIR spellings for now, with a TODO
for ABI-independent IDs.

Reapply "[SelectionDAG] Recurse through mask expression trees in WidenVSELECTMask" (#217307)
WidenVSELECTMask currently handles only two mask shapes: a bare SETCC
or a single AND/OR/XOR of exactly two SETCCs. Anything deeper bails out
to the generic condition widening path, which often introduces
unnecessary narrow/widen roundtrips (xtn+sshll on AArch64,
packssdw+vpmovsxwd on X86).
Replace the hand-coded cases with a recursive widenMaskTree that walks
through SETCC, AND/OR/XOR, FREEZE, VECTOR_SHUFFLE, SELECT/VSELECT, and
all-ones/all-zeros BUILD_VECTORs.
I had to revert #188085 earlier this year. This PR resolves the flagged
issue and cleans up suggested approach to avoid that class of potential
errors.

[ValueTracking] Make `getUnderlyingObjectsForCodegen()` preserve unidentified objects (#224584)
In some situations, it is useful to inspect the underlying objects of a
memory operation, even if they may alias with one another. A concrete
example comes from the approach to schedule DAG construction I've been
developing (see #205689) where these objects are used to infer that a
class of control dependencies between memory operations is redundant,
whereby eliminating the compile time cost of recording them. Update
`getUnderlyingObjectsForCodegen()` to return these objects.

[APFloat] Fix sign bit corrupting exponent in unsigned FP8 formats (#223286)
`convertIEEEFloatToAPInt` unconditionally ORs the sign bit into the top
bit of the encoded value. `Float8E8M0FNU` and `Float8E5M3FNU` have no
sign bit (`hasSignedRepr = false`), so that top bit actually belongs to
the exponent field. Encoding a value with sign set therefore corrupts
the exponent, in one case colliding with the reserved NaN bit pattern.
Guard the OR with `hasSignedRepr`, matching the existing check in the
decode path (`initFromIEEEAPInt`).
Extend `ConvertLosesUnrepresentableSignAndZero` to also check
`bitcastToAPInt()` after dropping an unrepresentable sign, using `-1.0`
instead of `-2.0` so the corruption is actually visible in the bits.

(bitcast to the scalar int type plus a compare for and/or, plus ctpop
for add). Choose the cheaper form by cost, estimating the bitcast-based
form from its emitted components; the ctpop form is estimated as the
cheaper of the scalar bitcast+ctpop and the vector ctpop on the mask

A later LiveVariables run recomputes those flags from scratch anyway, so
just clear possbly stale kill/dead flags on changed registers.
PPCMIPeephole was the only user of LiveVariables at this point in the
pipeline, so also drop the explicit LiveVariables run before
PPCTLSDynamicCallPass, whose comment references a > 10 year old build

[SLP]Emit loop-carried horizontal reductions as loop vector accumulator
A reduction whose root is the backedge value of a loop accumulator phi
is emitted as a lane-wise vector accumulator in the loop plus a single
reduction in the exit blocks, instead of a horizontal reduction on every
iteration. The loop-carried dependency chain becomes lane-wise and the
reduction is paid once per loop execution.
Note: It is partial vectorization within the loop, LV cannot handle it.
SLP already does something similar with multi-register reductions,
this adds another level - phi-based loop accumulator reductions.
