/* Recognizing signal handler frames. */
/* GNU/Linux has two flavors of signals. Normal signal handlers, and
"realtime" (RT) signals. The RT signals can provide additional
information to the signal handler if the SA_SIGINFO flag is set
when establishing a signal handler using `sigaction'. It is not
unlikely that future versions of GNU/Linux will support SA_SIGINFO
for normal signals too. */
/* When the sparc Linux kernel calls a signal handler and the
SA_RESTORER flag isn't set, the return address points to a bit of
code on the stack. This function returns whether the PC appears to
be within this bit of code.
The instruction sequence for normal signals is
mov __NR_sigreturn, %g1 ! hex: 0x821020d8
ta 0x10 ! hex: 0x91d02010
Checking for the code sequence should be somewhat reliable, because
the effect is to call the system call sigreturn. This is unlikely
to occur anywhere other than a signal trampoline.
It kind of sucks that we have to read memory from the process in
order to identify a signal trampoline, but there doesn't seem to be
any other way. However, sparc32_linux_pc_in_sigtramp arranges to
only call us if no function name could be identified, which should
be the case since the code is on the stack. */

ta {0x10,0x6d} ! hex: 0x91d02010 or 0x91d0206d

First, we need a data structure for use with ptrace(2). SunOS has
`struct regs' and `struct fp_status' in <machine/reg.h>. BSD's
have `struct reg' and `struct fpreg' in <machine/reg.h>. GNU/Linux
has the same structures as SunOS 4, but they're in <asm/reg.h>,
which is a kernel header. As a general rule we avoid including
GNU/Linux kernel headers. Fortunately GNU/Linux has a `gregset_t'
and a `fpregset_t' that are equivalent to `struct regs' and `struct
fp_status' in <sys/ucontext.h>, which is automatically included by
<signal.h>. Settling on using the `gregset_t' and `fpregset_t'
typedefs, providing them for the other systems, therefore solves
the puzzle. */

models, the traditional 32-bit data model (ILP32) and the 64-bit

of the observer (the controlling process, GDB in our case). The
Solaris header files conveniently define PR_MODEL_NATIVE to the

PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit

GNU/Linux uses the same formats as Solaris for its core files (but
not for ptrace(2)). The GNU/Linux headers don't define
PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define
provided by GCC to determine the appropriate data model.

convention, where the third argument is a pointer to an instance of
