I will do that.

That is done on purpose so that i386-tdep.c can have

/* Get the x86 target description from INFO. We support both
32bit and 64bit if BFD64 is defined. */
tdesc = info.target_desc;
if (! tdesc_has_registers (tdesc))
{
if (info.bfd_arch_info->bits_per_word == 32)
tdesc = tdesc_i386;
else
#ifdef BFD64
tdesc = tdesc_x86_64;
#else
return NULL;
#endif
}
gdb_assert (tdesc_has_registers (tdesc));
/* Get core registers. */
feature_core = tdesc_find_feature (tdesc, "org.gnu.gdb.i386.core");
if (feature_core == NULL)

to support both 32bit and 64bit, avoiding unnecessary complication and
code duplication. That is how it is done for PPC/RS6000.
