Under Linux/Glibc, GDB read DT_DEBUG from gdbserver too early?

[don dot lee at sunplusct dot com]

Hi all,

I'm now working on shared library support on a target GDB porting
(based on GDB 6.6), and we using Linux/Glibc as OS.

When I run 'target remote the-target:1234', GDB try to read
'.dynamic' section in the inferior address space, but looks like
at this moment the inferior is stopped at dynamic loader, and 
the DT_DEBUG didn't get a meaningful value.

Did I do something wrong?

Here is my osabi init function:

static void
score_linux_init_abi (struct gdbarch_info info, struct gdbarch *gdbarch)
{
  int target_mach = info.bfd_arch_info->mach;

  set_solib_svr4_fetch_link_map_offsets
    (gdbarch, svr4_ilp32_fetch_link_map_offsets);

  /* Shared library handling.  */
  set_gdbarch_skip_trampoline_code (gdbarch, 
find_solib_trampoline_target);
  set_gdbarch_skip_solib_resolver (gdbarch, score_linux_skip_resolver);

  /* Enable TLS support.  */
  set_gdbarch_fetch_tls_load_module_address (gdbarch,
                                             svr4_fetch_objfile_link_map);

  switch (target_mach)
    {
    case bfd_mach_score7:
      tramp_frame_prepend_unwinder (gdbarch,
 &score7_linux_rt_sigreturn_tramp_frame);

      /* Core file support. */
      set_gdbarch_regset_from_core_section (gdbarch, 
score7_linux_regset_from_core_section);
      break;
    }
}
