66 +--| saved sp |--> interrupted_sp
67 | | saved pc |--> interrupted_pc
70 | | saved lr |--> default_restorer (movz x8, NR_sys_rt_sigreturn; svc 0)
76 On signal delivery, the kernel will create a signal handler stack
77 frame and setup the return address in LR to point at restorer stub.
78 The signal stack frame is defined by:
91 The ucontext has the following form:
94 unsigned long uc_flags;
95 struct ucontext *uc_link;
98 struct sigcontext uc_mcontext;
101 typedef struct sigaltstack
110 unsigned long fault_address;
111 unsigned long regs[31];
112 unsigned long sp; / * 31 * /
113 unsigned long pc; / * 32 * /
114 unsigned long pstate; / * 33 * /
115 __u8 __reserved[4096]
118 The restorer stub will always have the form:
120 d28015a8 movz x8, #0xad
123 This is a system call sys_rt_sigreturn.
125 We detect signal frames by snooping the return code for the restorer
126 instruction sequence.
128 The handler then needs to recover the saved register set from
129 ucontext.uc_mcontext. */
