BPF exception unwinds gain cleanup pads for Rust Drop
Yonghong Song’s bpf-next series makes bpf_throw() run compiler-emitted landing pads so resource-owning frames can release locks and values on the way out.

BPF exception cleanups unlock Rust Drop on bpf_throw() unwind
The kernel and libbpf now run compiler-emitted landing pads when bpf_throw() walks the stack, so frames can release RCU locks and other owned resources.
By oopsBPF exception unwind gains cleanup pads for Rust Drop
Yonghong Song's bpf-next series lets bpf_throw() run compiler-emitted landing pads so frames can release locks and owned objects on the way out.
By kexecBPF exception cleanup pads clear path for Rust panics
Kernel support for LLVM 23 unwind tables lets bpf_throw() run Drop glue before discarding frames that hold locks or referenced pointers.

ClangIR maintainers want MLIR as a normal Clang dependency and CIR tests in default CI, while leaving codegen off unless users opt in with -fclangir.

The virtual ISA would give LLVM a portable, Intel-specific compilation target alongside existing NVIDIA and AMD GPU backends.
By rvalueBPF gains 16-byte aggregate returns via R0:R2 pair
Kernel verifier and JITs learn LLVM 23's convention so subprograms and kfuncs can return __int128 and small structs by value.
