Re: review request: implementing DW_AT_endianity

[Peeter Joot <peeter.joot@lzlabs.com>]

It looks like any talk of contribution (and perhaps review) is premature.  My initial test only had a big-endian structure, and the one I wrote describing what I wanted to address doesn't work (which I noticed only after sending my review request email).  The big-endian tagged structure does show up properly, but what I have done messes up the display of any little endian integers.  It appears that I end up setting my new big-endian flag inappropriately:


Breakpoint 1, print_scalar_formatted (valaddr=0x1e25260 "\003", type=0x1ce2670, options=0x7ffe20ac7490, size=0, stream=0x1c95a40)

    at ../../binutils-gdb/gdb/printcmd.c:355

355       struct gdbarch *gdbarch = get_type_arch (type);

(gdb) p *type->main_type

$1 = {code = TYPE_CODE_INT, flag_unsigned = 0, flag_nosign = 0, flag_stub = 0, flag_target_stub = 0, flag_static = 0,

  flag_prototyped = 0, flag_incomplete = 0, flag_varargs = 0, flag_vector = 0, flag_stub_supported = 0, flag_gnu_ifunc = 0,

  flag_fixed_instance = 0, flag_objfile_owned = 1, flag_endianity_big = 1, flag_endianity_little = 0, flag_declared_class = 0,

  flag_flag_enum = 0, type_specific_field = TYPE_SPECIFIC_NONE, nfields = 0, name = 0x1caacbc "int", tag_name = 0x0, owner = {

    objfile = 0x1c98620, gdbarch = 0x1c98620}, target_type = 0x0, flds_bnds = {fields = 0x0, bounds = 0x0}, type_specific = {

    cplus_stuff = 0x0, gnat_stuff = 0x0, floatformat = 0x0, func_stuff = 0x0, self_type = 0x0}, dyn_prop_list = 0x0}


This is when I'm printing a native endian integer, so do not want to have flag_endianity_big set.


I'm guessing that main_type is not the place for this flag, but it has to be in struct type instead.  Is that guess on the right track?
