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