[lldb] Make sure that the "TypeSystemClang::GetBuiltinTypeByName" method returns the correct value also for "_BitInt(...)" types. (#165857)
When trying to get the `SBType` object corresponding to the
`_BitInt(...)` type name, we have noticed that the
`SBTarget::FindFirstType` metod returns `nil`. This branch proposes:
- some test that demonstrate that the problem exists
- a possible fix

[TwoAddressInstruction] Track MadeChange when eliminating REG_SEQUENCE (#173535)
When `eliminateRegSequence()` is called, the pass modifies the
`MachineFunction` but `MadeChange` was not being set to true.
This causes the pass to incorrectly return `PreservedAnalyses::all()`
even though changes were made.
[clang][bytecode] Diagnose regular CK_LValueBitCast cast nodes (#175721)
We already do this similarly for CXXReinterpretCastExprs, except in that
case we try harder to make things work.
[LifetimeSafety] Merge lifetimebound attribute on implicit 'this' across method redeclarations (#172146)
Followup on https://github.com/llvm/llvm-project/pull/107627
Fixes https://github.com/llvm/llvm-project/issues/62072
Fixes https://github.com/llvm/llvm-project/issues/172013
Fixes https://github.com/llvm/llvm-project/issues/175391
This PR adds support for merging the `lifetimebound` attribute on the implicit `this` parameter when merging method declarations. Previously, if a method was declared with `lifetimebound` on its function type (which represents the implicit `this` parameter), this attribute would not be propagated to the method definition, causing lifetime safety warnings to be missed.
The implementation adds helper functions to extract the `lifetimebound` attribute from a function type and to merge this attribute from an old method declaration to a new one when appropriate.
[lldb][RISCV] Implement trap handler unwind plan (#166531)
This patch introduces special unwind plan for trap handling for RISC-V
and fixes `TestHandleAbort`
[RISCV] Sync Inst{30-27} assignment into RVPWideningBase. NFC (#175705)
2 of the 3 subclases can pass 'f' straight through from their
instantiations. The third case just needs to concatenate 1b1 to widen f
to 4 bits.
[LifetimeSafety] Add support for derived-to-base conversions (#175631)
Add support for derived-to-base conversions in lifetime analysis.
Added handling for `CK_UncheckedDerivedToBase` and `CK_DerivedToBase` cast kinds in the `FactsGenerator::VisitImplicitCastExpr` method. These cast kinds are now treated similarly to other conversions by flowing origins from source to destination.
Added a unit test `DerivedToBaseThisArg` that verifies lifetime information is correctly propagated through derived-to-base conversions when using member functions inherited from a base class.
net/frr: Changelog for v1.50 (#5133)
* net/frr: Changelog for v1.50
* Fix a helptext to be more generic and one string.
* Remove private AS should be advanced
[VPlan] Allow VPInstruction::PtrAdd as a user of EVL (#175506)
Fixes #175058
Similar to #175028, on RV64 we insert a zext in between most uses of EVL
so most of the VPlanVerifier EVL checks don't fire unless we're
compiling for RV32.
In this case, we're experiencing a crash because we can have a PtrAdd
that uses EVL. This fixes it by adding PtrAdd to the list of allowed
instructions
[clang][bytecode] Fix crash on arrays with excessive size (#175402)
The bytecode interpreter was crashing when seeing arrays with sizes that
exceed Descriptor::MaxArrayElemBytes. The bounds check in
Program::createDescriptor was using std::numeric_limits<unsigned>::max()
instead of the correct limit Descriptor::MaxArrayElemBytes.
This caused the check to pass for sizes that would later fail the
assertion in the Descriptor constructor.
Fixes #175293
[RISCV] Support RISCV BitInt larger than 128 (#175515)
fa57074d146925a303263905af415cc78f58f353 constraint the RISCV BitInt
with 128 bits.
It is due to fp <-> int convension will crash in backend.
(https://godbolt.org/z/9o1qr4rje)
This patch enable larger than 128 bits BitInt type by
`setMaxLargeFPConvertBitWidthSupported`.
net/frr: Add capability support for BGP neighbors (#5128)
* net/frr: Add capability support for BGP neighbors
I've recently tried to use OPNsense in an environment where the use of link-local addresses is required.
Since the link-local capability is not available, I was not able to use OPNsense then.
Obviously, there are some other with the same problem:
* [os-frr] wrong interface for IPv6 link-local used to connect to neighbor #4962
* https://forum.opnsense.org/index.php?topic=36088.0
So, I'd like to offer support for BGP capabilities.
* net/frr: Improve help string for BGP Capabilities as suggested by @Monviech
* net/frr: Fix typo as found by @Monviech
* net/frr: Remove not needed attribute as suggested by @Monviech
