28 /* Macros for handling per-gen compilation.
29  *
30  * The macro GENX() automatically suffixes whatever you give it with _vX
31  *
32  * You can do pseudo-runtime checks in your function such as
33  *
34  * if (PAN_ARCH == 4) {
35  *    // Do something
36  * }
37  *
38  * The contents of the if statement must be valid regardless of gen, but
39  * the if will get compiled away on everything except first-generation Midgard.
40  *
41  * For places where you really do have a compile-time conflict, you can
42  * use preprocessor logic:
43  *
44  * #if (PAN_ARCH == 75)
45  *    // Do something
46  * #endif
47  *
48  * However, it is strongly recommended that the former be used whenever
49  * possible.
