| // Helper function used by compiler to restore ppc floating point registers at |
| // the end of the function epilog. This function returns to the address |
| // in the LR slot. So a function epilog must branch (b) not branch and link |
| // (bl) to this function. |
| // If the compiler wants to restore f27..f31, it does a "b restFP+52" |
| // |
| // This function should never be exported by a shared library. Each linkage |
| // unit carries its own copy of this function. |
