| 215 | /* Before touching these macros, you owe it to yourself to go and | |
| 216 | * see how arch/sparc64/kernel/winfixup.S works... -DaveM | |
| 217 | * | |
| 218 | * For the user cases we used to use the %asi register, but | |
| 219 | * it turns out that the "wr xxx, %asi" costs ~5 cycles, so | |
| 220 | * now we use immediate ASI loads and stores instead. Kudos | |
| 221 | * to Greg Onufer for pointing out this performance anomaly. | |
| 222 | * | |
| 223 | * Further note that we cannot use the g2, g4, g5, and g7 alternate | |
| 224 | * globals in the spill routines, check out the save instruction in | |
| 225 | * arch/sparc64/kernel/etrap.S to see what I mean about g2, and | |
| 226 | * g4/g5 are the globals which are preserved by etrap processing | |
| 227 | * for the caller of it. The g7 register is the return pc for | |
| 228 | * etrap. Finally, g6 is the current thread register so we cannot | |
| 229 | * us it in the spill handlers either. Most of these rules do not | |
| 230 | * apply to fill processing, only g6 is not usable. | |
