[clang-linker-wrapper] Drop SYCL dry-run stub-image special case (#201222)
Remove the `DryRun` branch in `bundleSYCL` that emitted a stub
`OffloadBinary`. SYCL goes through the same empty-buffer path as other
offload kinds, so the special case is no longer needed.
Update `linker-wrapper-image.c` to expect the resulting `[0 x i8]
zeroinitializer` constant and a size of `0` in the register/unregister
calls.

[CIR] Set ExternalWeakLinkage on weak/weak_import function declarations (#198422)
Classic CodeGen's `SetFunctionAttributes` calls `setLinkageForGV` to force `ExternalWeakLinkage` on `__attribute__((weak))` and Darwin `weak_import` declarations. CIR had no equivalent: weak function declarations were emitted with `ExternalLinkage` instead of `ExternalWeakLinkage`.
This adds `setLinkageForFunction` — the same weak/external-weak logic as `setLinkageForGV` — and calls it from `setFunctionAttributes`. The underlying crash on inline forward declarations (the original motivation) is already fixed by #195257; what remains is this linkage gap.
`inline-forward-decl.c` covers `__attribute__((weak))` on an inline forward declaration; `func-linkage-weak-import.c` covers Darwin `weak_import` (→ `extern_weak` in CIR and LLVM).
[NVPTX] Fix aggregate load/store lowering for (potentially) overlapping copies (#201177)
NVPTXLowerAggrCopies lowers load/store pairs of large values into a loop
of smaller copies.
However, it was incorrectly assuming that the load/store pairs it found
never alias.
This patch adds an alias check. If the pointers may alias, we emit a
memmov, which handles overlap correctly.
CUDA reproducer:
typedef char vec __attribute__((vector_size(256)));
__global__ void boom(char *p) {
*(vec *)(p + 8) = *(vec *)p;
}

[lldb][debugserver] Arguments to kill(2) are reversed (#201226)
This codepath is only executed as an attempt to clean up during a failed
launch, so the reversed arguments were rarely actually used.

[VPlan] Don't expand SCEVs without uses to VPInstructions (NFC). (#201221)
If a VPExpandSCEVRecipe does not have users, there's no benefit to
expand it to VPInstructions, which then have to get cleaned up.
This also prevents DCE from removing VPInstructions pointed to by
TripCount after expansion.
[lldb] Have TestRunLocker run both styles of launch (#200978)
While debugging flakey behavior with TestRunLocker, I noticed that is
intended to run its test once with a stop at the entry function (and
then Continues) and once where we launch to the main() loop. But we were
never exercising the stop-at-entry codepath.
This doesn't fix the flakey behavior, although that only happens with
the launch-directly-into-main() codepath; I don't get failures when I
stop at the entry point and then continue.
[ORC] Make SimpleExecutorDylibManager::resolve an instance method. (#201211)
Promote the lambda inside resolveWrapper to a public method on
SimpleExecutorDylibManager. This brings SimpleExecutorDylibManager into
better alignment with the NativeDylibManager implementation in the new
ORC runtime, and is a step towards allowing NativeDylibManager to be
used as a drop-in replacement for SimpleExecutorDylibManager.
lacp: Simplify lacp_compose_key()
lacp uses interface speed to separate lacp members into different
aggregation groups. It wants to use the lower 4 bits of the key
to represent the speed. This change fixes a few bugs around that:
1) Actually use the baud rate reported by the interface as the speed
(and fall back to use the baudrate associated with the media if
the interface somehow doesn't support if_baudrate)
2) Compressess the baud rates down to the 4 bits reserved for them.
Using things like FM_400G_FR8 does not fit in 4 bits (its value
is 0x1811) . In fact, interfaces faster than 1Gb/s don't fit in
4 bits using the old scheme
3) Emits a warning on the console once per boot if it encounters a
NIC with an unsupported speed to make it slightly more obvious
why LACP might not behave as expected.

[RISCV][GISel] Add GPRPair to GPRB register bank and use getXLen() for GPRSize
Map GPRPair register classes to the GPRB register bank during GlobalISel
instruction selection. This is required because the introduction of HwMode-dependent
base pointer register classes (e.g. via PtrRegClassByHwMode) causes TableGen to
emit register bank checks for GPRPair variants in RISCVGenGlobalISel.inc.
Without this mapping, instruction selection crashes on unsupported classes.
To avoid assertion failures when GPRB's maximum size increases to 128-bit on RV64
due to the register pairs, update RISCVRegisterBankInfo::getInstrMapping to query
Subtarget.getXLen() for the scalar register width instead of relying on the bank's
getMaximumSize(). This matches AArch64's design pattern of mapping register pairs
(XSeqPairsClass) to GPR and resolving scalar register sizes dynamically.
This was fine previously but was exposed by the HwMode changes in
https://github.com/llvm/llvm-project/pull/177073.

graphics/atril: switch to GitHub release asset
Minor versions of 1.28.x are no longer published to the MATE mirror
and are only available on GitHub. Use USE_GITHUB=nodefault with a
release tarball instead of the auto-generated one, as recommended
by the porter's handbook.
[mlir][bytecode] Add option to elide locations during serialization (#201183)
Adds a setElideLocations option to BytecodeWriterConfig to elide
locations during bytecode serialization. When enabled, all LocationAttrs
are mapped to UnknownLoc during numbering and writing to produce
location-invariant bytecode (e.g., for stable fingerprinting).
Another way to achieve the same thing would be to apply the
strip-debuginfo pass,
but that requires mutating the module, which in turn requires cloning
the module if one still requires the unstripped original.
