Why it can't have same name? See, how _AC() macro is defined and being used. > +#define ENCLS_TRAPNR(r) ((r) & ~ENCLS_FAULT_FLAG) If result of macro is assigned to some variable and (r) by some reason is 32-bit type and you compile as 64-bit object, compiler will warn here. Please, check this is not the case in any of use of this macro. Otherwise you need a type casting, like foo = bar & (u32)~BAR; (or using typeof() might work) -- With Best Regards, Andy Shevchenko
