it is StdLib specific and other functions like abort are using it already. from StdLib/Include/sys/EfiCdefs.h: #if __GNUC_PREREQ__(2, 7) #define __unused __attribute__((__unused__)) #define __noreturn __attribute__((__noreturn__)) #else #define __unused /* delete */ #define __noreturn /* delete */ #endif
do other compilers(VC?) really don't need this or should we treat it as not being implemented? This page shows that there's sth. called '__declspec(noreturn)': https://msdn.microsoft.com/en-us/library/k6ktzx3s.aspx but obviously there are even more compilers than just gcc and vc.
