Upstreaming ClangIR (CIR), Clang's MLIR-based IR, through public code review since March 2025.

C++20 coroutines

27 of 27

End-to-end coroutine support in ClangIR: emitting the coroutine body and promise, cir.await with ready/suspend/resume branches, co_yield and co_return, structured control flow for suspend points, FlattenCFG for coroutine ops, and dedicated cir.coro.* intrinsic ops with LLVM lowering.
