Alternatively, there is another compiler-defined macro _CET_ENDBR that can
be used. We can put the following in calling.h:
#ifdef __CET__
#include <cet.h>
#else
#define _CET_ENDBR
#endif
and then use _CET_ENDBR in other files. How is that?
In the future, in case we have kernel-mode IBT, ENDBR macros are also needed
for other assembly files.
Can we please call it IBT_ENDBR or just ENDBR. CET is a horrible name,
seeing how it is not specific.
_CET_ENDBR is from the compiler and we cannot change it. We can do:
#define ENDBR _CET_ENDBR
How is that?
