URL: https://github.com/llvm/llvm-project/commit/8f8590e691fe772b321004118ae92f5230c8a94d DIFF: https://github.com/llvm/llvm-project/commit/8f8590e691fe772b321004118ae92f5230c8a94d.diff LOG: [OpenMP][AIX] Add libpthreads for -fopenmp (#184629) The compiler uses TLS for OpenMP thread‑private data, which results in references to symbols such as `__tls_get_addr` in `libpthreads`. Therefore, this PR adds `libpthreads` to the link command when `-fopenmp` is specified.
