* Userspace ABI: Register state needed by
|
|
* -ptrace (gdbserver)
|
|
* -sigcontext (SA_SIGNINFO signal frame)
|
|
*
|
|
* This is to decouple pt_regs from user-space ABI, to be able to change it
|
|
* w/o affecting the ABI.
|
|
*
|
|
* The intermediate pad,pad2 are relics of initial layout based on pt_regs
|
|
* for optimizations when copying pt_regs to/from user_regs_struct.
|
|
* We no longer need them, but can't be changed as they are part of ABI now.
|
|
*
|
|
* Also, sigcontext only care about the scratch regs as that is what we really
|
|
* save/restore for signal handling. However gdb also uses the same struct
|
|
* hence callee regs need to be in there too.
