URL: https://github.com/llvm/llvm-project/commit/465a3ce9fac1fcf49d5772f70564973a73748d57 DIFF: https://github.com/llvm/llvm-project/commit/465a3ce9fac1fcf49d5772f70564973a73748d57.diff LOG: [CUDA][HIP] improve error message for missing cmath (#122155) One common error seen in CUDA/HIP compilation is: fatal error: 'cmath' file not found which is due to inproper installation of standard C++ libraries. Since it happens with #include_next, users may feel confusing which cmath is not found and how to fix it. Add an error directive to help users resolve this issue.
