21 | * -sigcontext (SA_SIGNINFO signal frame) | |
22 | * | |
23 | * This is to decouple pt_regs from user-space ABI, to be able to change it | |
24 | * w/o affecting the ABI. | |

26 | * The intermediate pad,pad2 are relics of initial layout based on pt_regs | |
27 | * for optimizations when copying pt_regs to/from user_regs_struct. | |
28 | * We no longer need them, but can't be changed as they are part of ABI now. | |

29 | * |
30 | * Also, sigcontext only care about the scratch regs as that is what we really | |
2fa91904 VG |
31 | * save/restore for signal handling. However gdb also uses the same struct |
32 | * hence callee regs need to be in there too. | |
