/* Macros for handling per-gen compilation.

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.
