| 18 | * Userspace ABI: Register state needed by | |
| 19 | * -ptrace (gdbserver) | |
| 20 | * -sigcontext (SA_SIGNINFO signal frame) | |
| 21 | * | |
| 22 | * This is to decouple pt_regs from user-space ABI, to be able to change it | |
| 23 | * w/o affecting the ABI. | |

24 | * |
| 25 | * The intermediate pad,pad2 are relics of initial layout based on pt_regs | |
| 26 | * for optimizations when copying pt_regs to/from user_regs_struct. | |
| 27 | * We no longer need them, but can't be changed as they are part of ABI now. | |
| 8c2f4a8d VG |
28 | * |
| 29 | * Also, sigcontext only care about the scratch regs as that is what we really | |
| 2fa91904 VG |
30 | * save/restore for signal handling. However gdb also uses the same struct |
| 31 | * hence callee regs need to be in there too. | |
