a signal-trampoline, assume that it's a PLT stub.
If non-DWARF stepping fails to change IP and CFA, declare
it a bad frame.

(unw_step): Also print IP as part of the function-trace.

(unw_step): When dwarf_step() fails on a signal-frame, fill in all
the known locations because dwarf_step() fails on older
kernels which don't export the kernel vDSO even though every-
thing else may be providing proper DWARF unwind-info.

Add Debug statement for return-value.

(my_rt_sigreturn): New function.
(x86_64_local_resume): Use my_rt_sigreturn(). The normal sigreturn()
does nothing (returns with an error).
2004/11/23 18:01:09-08:00 mostang.com!davidm
(x86_64_local_resume): Provide a minimal implementation (a la x86).
(establish_machine_state): Fix off-by-one error.

eh_valid_mask instead. When reading and the corresponding
eh_valid_mask bit is set, read from eh_args[] instead.

(tdep_access_reg): Treat UNW_X86_64_RSP exactly like UNW_X86_64_CFA.

In theory, this may not be needed. In practice, I find that
Red Hat Enterprise Linux AS release 3, the _start() routine has
no unwind-info, but we need to be able to unwind into this
routine to find the end-of-frame-chain marker (RBP == 0).
