Git commit 83ba8addf60668a971453eed207f9bfdaa379f97 by GitHub (on behalf of Andrew Haberlandt) on 20/07/2026 at 17:18..
[compiler-rt] Move sanitizer ignorelists to sanitizer-ignorelists target (#200518)
This adds a `sanitizer-ignorelists` target to compiler-rt, allowing the
ignorelists to be built independently of the sanitizer runtimes. The
ignorelists are still built by default, but this change is not quite
NFC: when any of the sanitizers are built, all of the ignorelists will
be included (rather than the individual runtime ignorelists being built
with their respective runtimes).
For _why_ we want to be able to build these independently of the
runtimes, see
https://github.com/llvm/llvm-project/pull/195690#issuecomment-4384573223
I did not move the dfsan abilist to this new target because it is not as
straightforward as a copying a static file.

[libc++][docs] Avoid talking about other implementations on DR status (#210637)
Standard library implementations consistently treat (or will
consistently treat) some LWG papers as Defect Reports that are also
applied to old modes, despite that they are not officially listed as
Defect Reports in WG21 meeting minutes. We used to say "other
implementations (namely MSVC STL and libstdc++) will do the same" for
some of them.
However, such sentences will become outdated soon when other
implementations actually do so. It is possibly better to avoid saying
so, which potentially requires synchronizing our documentation with
other implementations.

[llvm-readobj] Print all callgraph sections (#198929)
Ensure that `llvm-readobj` / `llvm-readelf` processes and dumps all
SHT_LLVM_CALL_GRAPH sections present in an object file, rather
than just the first one.
**Motivation:**
Consider this `foo.s` file
```
.pushsection .text, "axG", %progbits, foo
.globl foo
foo:
ret
.pushsection .llvm.callgraph, "?", %llvm_call_graph
.byte 0, 0
.dc.a foo
.quad 0
.popsection
.popsection
.pushsection .text, "axG", %progbits, bar
.globl foo
bar:
ret
.pushsection .llvm.callgraph, "?", %llvm_call_graph
.byte 0, 0
.dc.a bar
.quad 0
.popsection
.popsection
```
`clang -c foo.s && llvm-readelf --elf-output-style=JSON --pretty-print
--call-graph-info foo.o` on that shows that there is only one record
reported because the current implementation just looked at the first
SHT_LLVM_CALL_GRAPH section and then ignored all others. This patch will
address this gap by iterating over all the SHT_LLVM_CALL_GRAPH sections.

[LFI][libunwind] Omit unsuppported stg/za instructions for LFI target (#209392)

neither is the `stg` instruction. When included in an LFI program they
cause verification failures due to being unsupported instructions. This
patch omits them from compilation when targeting LFI.

[LoopUnroll] Add `prepare-for-lto` pass option (#192153)
Expose `UnrollCostEstimator`'s `PrepareForLTO` flag as a pass option for
`LoopUnrollPass` and `LoopFullUnrollPass`. When enabled, loops
containing calls that may be inlined during the LTO post-link phase are
left rolled in the pre-link phase, deferring the decision until LTO
post-link inlining has completed.

[ELF] Apply version script patterns to name-versioned definitions by node (#208882)
Like GNU ld, a definition whose name specifies a version (foo@@v1 or
foo@v1) should be governed solely by its own version node, with global
patterns checked before local ones and no exact-over-wildcard
precedence. Also fix #202259 (`local: foo*` does not localize defined
`foo@@v1`)
```
old new (= GNU ld)
symbol foo@@v1
v1 { local: foo; } (own node) localized localized
v2 { local: foo; } (other node) localized exported
v1 { local: foo*; } (own node) exported localized
v1 { local: *; } (own node) exported localized
v1 { global: foo*; local: foo; } localized exported
symbol foo3@v1
v1 { global: foo3*; local: foo3; } localized exported
v1 { global: *; local: foo3*; } localized exported
```
assignExactVersion now skips name-versioned symbols, and the
synthesized "pat@v1" patterns and includeNonDefault parameters are
removed. Instead, parseSymbolVersion matches the version-less name
(demangled for extern "C++" patterns) against the symbol's own node,
localizing the symbol if a local: pattern matches and no global:
pattern does. An exact pattern still performs a "pat@v1" lookup so that
a pattern matching only foo@v1 is not reported as undefined. "attempt
to reassign" diagnostics no longer apply to name-versioned symbols.

Git commit a04f87fdd9b59c6089bf731c669c6f149208363c by GitHub (on behalf of Haowei) on 20/07/2026 at 17:47..
Reapply "Skipping host target exports during cross-compilation" (#210… (#210496)
This reverts commit 42eb7db188f23625872b6f1d722979a3100d170e. This
reland 3fbb037d03e7ff1ef1cd9156363e895af7caaf98 (#209922).
Under CMake 4+, calling add_library(... SHARED IMPORTED) on a target
platform that lacks dynamic linking support triggers a fatal error. This
becomes an issue when building LLVM and runtimes for baremetal targets
like armv6m-none-eabi. This patch adds the option
"LLVM_OMIT_EXPORTS_FROM_CONFIG" in LLVM. When used in sub builds like
LLVM runtimes, it makes CMake to skip including the LLVM and Clang
exports. This mitigates the CMake 4 errors on baremetal runtimes.
42eb7db188f23625872b6f1d722979a3100d170e originally
apply this flag on all runtimes build and causing issues on runtimes
like intel-sycl-gpu, amdgpu-offload-ubuntu-22-cmake-build-only.
This PR only set this flag when the target platform lacks shared library
support.

[libunwind] Fix exposure of UNW_AARCH64_RA_SIGN_STATE through _Unwind_GetGR (#209947)
The pseudo register was previously hacked in under kRegisterIsUndefined, leaving it in a state that was only accessible from within the unwinder itself.
To fix this, allowing external access to the state (and therefore tests!), we invent a new register location kRegisterIsPseudo to record the additional state that the register has been defined by a .cfi_negate_ra_state opcode having been executed.

[AMDGPU] Calculate div/rem with frcp more efficiently (#210684)
Integer division q = a/b can be implemented by fp reciprocal with:
fq = fa * recip(fb)
fq is truncated to produce q. Due to fp rounding and reciprocal accuracy
issues fq can be too small and truncation can produce a value too small
by one.
If abs(a)<=0x400000, this underestimate can be guarded more efficiently
by calculating:
fq=fa+1ulp/b
If abs(a)<=0x400000, adding 1 ulp will increase a by at most 0.5, so the
calculated q will be the same. Adding 1ulp can be done with one integer
add.
This change is analogous to the change done in
https://github.com/llvm/llvm-project/pull/204950 but in
AMDGPUISelLowering.cpp.

[LSV] Don't vectorize load chains across ordered atomics (#208631)
When the LoadStoreVectorizer finds a chain of loads to merge into a
single vectorized load, it hoists all of the constituent loads up to the
location of the first load in the chain.
This is obviously not safe if there are any may-alias stores in the
middle of the chain. But it's *also* not safe if there are `acquire`
*loads* in the middle of the chain.
There's a similar problem with stores. A chain of stores is vectorized
by merging them all into the final store in the chain. This is not safe
if there is an intervening `release` store.

[MLIR][XeGPU] Add local forward layout propagation (#208932)
Backward layout propagation only assigns layouts to values that are
(transitively) consumed by an anchor op. A value whose only consumer is,
e.g., the next iteration of a loop is left without a layout.
Add a local forward-fill step, run after the backward materialization
walk in propagateLayouts(): it visits ops in producer-first order and,
for any un-laid-out vector result, infers the layout from the op's
already-known operand layouts via a new
inferResultLayoutFromSourceForNonAnchorOp dispatcher (covering
elementwise, transpose, and shape_cast; other ops are left as TODO),
then stamps it with setDistributeLayoutAttr.

[lldb-mcp] Host managed debug sessions in-process (#210450)
Let a client create and own debug sessions with session_create and
session_close. Rather than spawn a separate lldb per session, lldb-mcp
hosts them in its own process, communicating over a loopback socket to
keep things uniform with external lldb instances.
The benefits of this approach are:
- There is no child-process machinery, so nothing needs to be spawned
and cleaned up.
- It works without the need for an external lldb binary.
- It avoids the deadlock by reading stdin through a raw fd instead of
the FILE* stdio path that previously hung the Debugger constructor
contending on the REPL's stdin lock.
- The architecture stays uniform between in-process and external
sessions.
The trade-off is no isolation, so an LLDB crash takes down lldb-mcp
along with its proxied connections.

[LoopUnroll] Remove `Count` from `UnrollingPreferences` (NFC) (#203413)
`UnrollingPreferences` is a way for targets to specify their preferences
to the unroller. The unroller uses `UnrollingPreferences` to guide what
kinds of unrolling to consider while also co-opting it to encode the
specific kind of unrolling it's chosen to attempt.
One preference targets can set is the `Count`, or the number of times
the loop in question will be unrolled:
```
/// A forced unrolling factor (the number of concatenated bodies of the
/// original loop in the unrolled loop body). When set to 0, the unrolling
/// transformation will select an unrolling factor based on the current cost
/// threshold and other factors.
unsigned Count;
```
However, there are no in-tree uses of this functionality, and it does
not work. [Loop

all override the value of `UP.Count` that targets would've set. This
appears to have been broken since LLVM 3.9 days as a result of
ea2aef4a1d4beded20033fa4fc223936c7ffe5d8.
This PR removes `Count` from `UnrollingPreferences` and instead encodes
it as a return value of the `computeUnrollCount()` family of functions.
If [out-of-tree targets want to begin setting
`Count`](https://github.com/llvm/llvm-project/pull/185979#discussion_r3022857799),
their best bet is likely to use
[`llvm.loop.unroll.count`](https://llvm.org/docs/LangRef.html#llvm-loop-unroll-count-metadata).

[SPIRV] SPIRVTools custom targets should not have executable suffix (#210773)
This looks like it was likely a copy paste mistake. When we invoke the
binary via the cmake command yes we need the executable suffix. but the
custom target name is the same across all OSes.
This bug manifests itself on Windows when you add
-DLLVM_INCLUDE_SPIRV_TOOLS_TESTS=ON to the cmake.

relative paths for a few cases. This adds it to the other case, should

[lldb] Avoid data race when clearing an OptionValue (#208471)
The clear function guarded by the internal mutex.
This happens when we have to threads one trying to set a value and the
other reseting the value.
The derived classes are forced to implement the `ClearImpl`. and base
`OptionValue` hold the mutex and calls `ClearImpl` on clear.

[mlir][acc] Lower per-thread array reductions correctly (#210453)
Lowering an acc.reduction_accumulate_array to a per-element
gpu.all_reduce is only valid when each thread owns its own accumulator
copy. This was inferred from the memref's static size, which was wrong
for dynamically-shaped accumulators and for storage seen through
descriptor or strided views.
Per-thread accumulators that fit the local stack budget are materialized
in stack memory; anything larger, or gang-scoped, is materialized in
shared memory. Classify from that: a stack alloca (or a view over one)
within the budget is per-thread, a shared allocation is block-shared,
and a dynamically-shaped accumulator is classified from its par_dims.
Materialization and predication follow the same rule, and writes to a
privatization are recognized through views/casts so per-thread setup
runs on every owning thread.

[NewPM] Only add passes after optimized RegAlloc if a target enables it
The legacyPM allows for returning a boolean from
addRegAssignAndRewriteOptimized, and if set to false, some extra passes
at the end of addOptimizedRegAlloc are not added. Before this patch, the
NewPM would only omit adding these passes if an error was thrown, which
gets propagated all the way back up and prevents compilation.
This is necessary behavior for targets that do not perform register
allocation, like WebAssembly, that will otherwise crash in places like
MachineLICM.
