/* 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 (GFX_VERx10 == 75) {
|
|
* // 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 (GFX_VERx10 == 75)
|
|
* // Do something
|
|
* #endif
|
|
*
|
|
* However, it is strongly recommended that the former be used whenever
|
|
* possible.
