gdb/
* remote.c (remote_check_symbols): Use
gdbarch_convert_from_func_ptr_addr.
* infcall.c (find_function_addr): Handle function descriptors
without debugging information.
* ppc-linux-tdep.c (ppc_linux_convert_from_func_ptr_addr): Renamed
from ppc64_linux_convert_from_func_ptr_addr. Handle -msecure-plt.
(ppc_linux_init_abi): Always set convert_from_func_ptr_addr.
* solib-svr4.c (solib_break_names): Remove "._dl_debug_state".
(bfd_lookup_symbol): Do not take a SECT_FLAGS argument. Always
allow SEC_CODE and SEC_DATA.
(enable_break): Update calls. Pass current_target to solib_add.
Use gdbarch_convert_from_func_ptr_addr.
gdb/gdbserver/
* remote-utils.c (look_up_one_symbol): Handle 'm' packets.
