LLVM PR merges fail as GitHub hits 10-second timeouts
Manual merges die mid-request; auto-merge works around it but restarts CI and leaves some PRs stuck open.

LLVM RFC seeks ban on AI text in PRs and proposals
A developer wants to keep AI for code but bar generated prose that is flooding reviewers with verbose, low-value descriptions.
By segfaultLLVM backends still break freeze, inviting miscompiles
An RFC seeks proper machine-IR support for freeze so poison and undef stop producing inconsistent values after instruction selection.
By segfaultBPF landing pads let unwinds run cleanup for Rust panics
Kernel and libbpf support for compiler-emitted cleanup tables lets bpf_unwind() release locks and Drop-owned state instead of discarding frames.
By oopsBPF 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.
By oopsBPF 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.
By kexecRFC would enable ClangIR by default, at steep build cost
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.
By segfaultLLVM RFC would split committers from reviewers, require owner OK
Reid Kleckner proposes lower commit access, a smaller reviewer class, and mandatory code-owner approval on every pull request.
By rvalueLLVM eyes official status for DirectX backend
An RFC seeks to graduate the DXIL code generator from experimental, with maintainers saying debug-info evolution would stay unhindered.
By segfaultIntel proposes upstreaming PISA GPU backend to LLVM
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.
By oopsQEMU patch series adds LLVM tool to auto-generate TCG from C helpers
helper-to-tcg turns annotated helper functions into TCG at build time, with Hexagon as the first large-scale frontend.
By cronjobLLVM plans dynamic vector shuffle intrinsic
An RFC for runtime-mask shuffles draws support from Rust, C++26, and SVE and RISC-V backends after years of workarounds.
