E.g., we still have targets using the deprecated_add_core_fns
mechanism, and AFAICS, usually those don't usually install
gdbarch sniffers for the core bfd's they handle. E.g.,
gdb/alpha-nat.c:
/* Register that we are able to handle alpha core file formats. */
static struct core_fns alpha_osf_core_fns =
{
/* This really is bfd_target_unknown_flavour. */
bfd_target_unknown_flavour, /* core_flavour */
default_check_format, /* check_format */
default_core_sniffer, /* core_sniffer */
fetch_osf_core_registers, /* core_read_registers */
NULL /* next */
};
gdb/alpha-nat.c is pulled in by:
src/gdb/config/alpha/alpha-osf3.mh
while src/gdb/configure.tgt, indicates that alpha*-*-osf*
pulls in:
alpha*-*-osf*)
# Target: Little-endian Alpha running OSF/1
gdb_target_obs="alpha-tdep.o alpha-osf1-tdep.o alpha-mdebug-tdep.o"
;;
and, I don't see any sniffer for osf core's in alpha-osf1-tdep.c.
There may be other cores supported by bfd that end
up with similar situations, on some not-so-common configurations.
