Both targets define DISPLACED_MODIFIED_INSNS, each with different values. Add ARM_ and AARCH64_ to the start of the name to prevent confusion. No functionality changes. gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_linux_init_abi): Use AARCH64_DISPLACED_MODIFIED_INSNS. * aarch64-tdep.c (struct aarch64_displaced_step_data) (aarch64_displaced_step_copy_insn): Likewise. * aarch64-tdep.h (DISPLACED_MODIFIED_INSNS): Rename from.. (AARCH64_DISPLACED_MODIFIED_INSNS): ...to this. * arm-linux-tdep.c (arm_linux_cleanup_svc): Use ARM_DISPLACED_MODIFIED_INSNS. * arm-tdep.c (arm_gdbarch_init): Likewise. * arm-tdep.h (DISPLACED_MODIFIED_INSNS): Rename from.. (ARM_DISPLACED_MODIFIED_INSNS): ...to this. (struct arm_displaced_step_closure): Use ARM_DISPLACED_MODIFIED_INSNS.

|
|
|
|
On signal delivery, the kernel will create a signal handler stack
|
|
frame and setup the return address in LR to point at restorer stub.
|
|
The signal stack frame is defined by:
|
|
|
|
struct rt_sigframe
|
|
{
|
|
siginfo_t info;
|
|
struct ucontext uc;
|
|
};
|
|
|
|
The ucontext has the following form:
|
|
struct ucontext
|
|
{
|
|
unsigned long uc_flags;
|
|
struct ucontext *uc_link;
|
|
stack_t uc_stack;
|
|
sigset_t uc_sigmask;
|
|
struct sigcontext uc_mcontext;
|
|
};
|
|
|
|
struct sigcontext
|
|
{
|
|
unsigned long fault_address;
|
|
unsigned long regs[31];
|
|
unsigned long sp; / * 31 * /
|
|
unsigned long pc; / * 32 * /
|
|
unsigned long pstate; / * 33 * /
|
|
__u8 __reserved[4096]
|
|
};
|
|
|
|
The reserved space in sigcontext contains additional structures, each starting
|
|
with a aarch64_ctx, which specifies a unique identifier and the total size of
|
|
the structure. The final structure in reserved will start will a null
|
|
aarch64_ctx. The penultimate entry in reserved may be a extra_context which
|
|
then points to a further block of reserved space.
|
|
|
|
struct aarch64_ctx {
|
|
u32 magic;
|
|
u32 size;
|
|
};
|
|
|
|
The restorer stub will always have the form:
|
|
|
|
d28015a8 movz x8, #0xad
|
|
d4000001 svc #0x0
|
|
|
|
This is a system call sys_rt_sigreturn.
|
|
|
|
We detect signal frames by snooping the return code for the restorer
|
|
instruction sequence.
|
|
|
|
The handler then needs to recover the saved register set from
|
|
ucontext.uc_mcontext. */
