| 29 | * The sigreturn() system call. | |
| 30 | * | |
| 31 | * The M98K sigcontext structure is more robust than older cousins. | |
| 32 | * This routine is responsible for restoring register state | |
| 33 | * based on the setting of sc_regs_saved before trapping into the | |
| 34 | * kernel. See <bsd/m98k/signal.h> | |
