27/* Macros for handling per-gen compilation.
28 *
29 * The prefixing macros GENX() and genX() automatically prefix whatever you
30 * give them by GENX_ or genX_  where X is the gen number.
31 *
32 * You can do pseudo-runtime checks in your function such as
33 *
34 * if (GFX_VERx10 == 75) {
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 haswell.
40 *
41 * For places where you really do have a compile-time conflict, you can
42 * use preprocessor logic:
43 *
44 * #if (GFX_VERx10 == 75)
45 *    // Do something
46 * #endif
47 *
48 * However, it is strongly recommended that the former be used whenever
49 * possible.
