| // Clang headers like to use NDEBUG inside of them to enable/disable debug |
| // releated features using "#ifndef NDEBUG" preprocessor blocks to do one thing |
| // or another. This is bad because it means that if clang was built in release |
| // mode, it assumes that you are building in release mode which is not always |
| // the case. You can end up with functions that are defined as empty in header |
| // files when NDEBUG is not defined, and this can cause link errors with the |
| // clang .a files that you have since you might be missing functions in the .a |
| // file. So we have to define NDEBUG when including clang headers to avoid any |
| // mismatches. This is covered by rdar://problem/8691220 |
