/* Macros for handling per-gen compilation.
*
* The macro GENX() automatically suffixes whatever you give it with _vX
*
* You can do pseudo-runtime checks in your function such as
*
* if (PAN_ARCH == 4) {
* // Do something
* }
*
* The contents of the if statement must be valid regardless of gen, but
* the if will get compiled away on everything except first-generation Midgard.
*
* For places where you really do have a compile-time conflict, you can
* use preprocessor logic:
*
* #if (PAN_ARCH == 75)
* // Do something
* #endif
*
* However, it is strongly recommended that the former be used whenever
* possible.
