/* Macros for handling per-gen compilation.
*
* The prefixing macros GENX() and genX() automatically prefix whatever you
* give them by GENX_ or genX_ where X is the gen number.
*
* You can do pseudo-runtime checks in your function such as
*
* if (GEN_GEN > 8 || GEN_IS_HASWELL) {
* // Do something
* }
*
* The contents of the if statement must be valid regardless of gen, but
* the if will get compiled away on everything except haswell.
*
* For places where you really do have a compile-time conflict, you can
* use preprocessor logic:
*
* #if (GEN_GEN > 8 || GEN_IS_HASWELL)
* // Do something
* #endif
*
* However, it is strongly recommended that the former be used whenever
* possible.
