URL: https://github.com/llvm/llvm-project/commit/4bad635155fae1a5dfefc2ab97e52cba7a8cb2a0 DIFF: https://github.com/llvm/llvm-project/commit/4bad635155fae1a5dfefc2ab97e52cba7a8cb2a0.diff LOG: [CIR] Fix -fopenacc crash on functions without a declaration (#230338) Functions that CIRGen create such as the atomic functions coming from `createRuntimeFunction` have no declaration. These cannot have an OpenACC routine decl. Check for the existence of a declaration first.
