// 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
