| 112 | * Hypercall register clobber list | ||
| 113 | * | ||
| 114 | * These macros are used to define the list of clobbered registers during a | ||
| 115 | * hypercall. Technically, registers r0 and r3-r12 are always clobbered, | ||
| 116 | * but the gcc inline assembly syntax does not allow us to specify registers | ||
| 117 | * on the clobber list that are also on the input/output list. Therefore, | ||
| 118 | * the lists of clobbered registers depends on the number of register | ||
| 119 | * parmeters ("+r" and "=r") passed to the hypercall. | ||
| 120 | * | ||
| 121 | * Each assembly block should use one of the HCALL_CLOBBERSx macros. As a | ||
| 122 | * general rule, 'x' is the number of parameters passed to the assembly | ||
| 123 | * block *except* for r11. | ||
| 124 | * | ||
| 125 | * If you're not sure, just use the smallest value of 'x' that does not | ||
| 126 | * generate a compilation error. Because these are static inline functions, | ||
| 127 | * the compiler will only check the clobber list for a function if you | ||
| 128 | * compile code that calls that function. | ||
| 129 | * | ||
| 130 | * r3 and r11 are not included in any clobbers list because they are always | ||
| 131 | * listed as output registers. | ||
| 132 | * | ||
| 133 | * XER, CTR, and LR are currently listed as clobbers because it's uncertain | ||
| 134 | * whether they will be clobbered. | ||
| 135 | * | ||
| 136 | * Note that r11 can be used as an output parameter. | ||
