3 * const.h: Macros for dealing with constants.
9 /* Some constant macros are used in both assembler and
10 * C code. Therefore we cannot annotate them always with
11 * 'UL' and other type specifiers unilaterally. We
12 * use the following macros to deal with this.
14 * Similarly, _AT() will cast an expression with a type in C, but
15 * leave it unchanged in asm.
21 #define _AT(T,X) ((T)(X))
24 #define _BITUL(x) (_AC(1,UL) << (x))
25 #define _BITULL(x) (_AC(1,ULL) << (x))
