  26 /* Macros for handling per-gen compilation.
  27  *
  28  * The prefixing macros GENX() and genX() automatically prefix whatever you
  29  * give them by GENX_ or genX_  where X is the gen number.
  30  *
  31  * You can do pseudo-runtime checks in your function such as
  32  *
  33  * if (GEN_GEN > 8 || GEN_IS_HASWELL) {
  34  *    // Do something
  35  * }
  36  *
  37  * The contents of the if statement must be valid regardless of gen, but
  38  * the if will get compiled away on everything except haswell.
  39  *
  40  * For places where you really do have a compile-time conflict, you can
  41  * use preprocessor logic:
  42  *
  43  * #if (GEN_GEN > 8 || GEN_IS_HASWELL)
  44  *    // Do something
  45  * #endif
  46  *
  47  * However, it is strongly recommended that the former be used whenever
  48  * possible.
