Hi,
I got a some error with multi-arch gdb and a mips core file:
(gdb) core-file ~/tmp/vmcore
warning: "/home/teawater/tmp/vmcore": ambiguous core format, 2 handlers match
warning: wrong size gregset struct in core file
warning: wrong size gregset struct in core file
#0 0x0000000000000000 in ?? ()
(gdb)
This error because sniff_core_bfd return cris_elf_core_fns. So GDB
use cris_elf_core_fns.fetch_core_registers to analyze this mips core.
It return cris_elf_core_fns because core_sniffer of cris_elf_core_fns
and mips-linux-tdep.c:regset_core_fns is default_core_sniffer.
So I think this is not fit with the multi-arch.
Do you think we can begin move deprecated_add_core_fns to
set_gdbarch_regset_from_core_section?
BTW, core_vec->core_read_registers have a argument "which" that
gdbarch_regset_from_core_section doesn't have. Do you think we can
add one to it?
Thanks,
Hui
