XCOFF relocations aren't defined only by the type field r_type.
The bitsize and whether they are signed or not, are defined by

This table contains the "default" relocation and few modified
relocations what were already there. It's enough when
xcoff_rtype2howto is called.
For relocations from an input bfd to an output bfd, the default

/* XCOFF archive support. The original version of this code was by
Damon A. Permezel. It was enhanced to permit cross support, and
writing archive files, by Ian Lance Taylor, Cygnus Support.
XCOFF uses its own archive format. Everything is hooked together
with file offset links, so it is possible to rapidly update an
archive in place. Of course, we don't do that. An XCOFF archive
has a real file header, not just an ARMAG string. The structure of
the file header and of each archive header appear below.
An XCOFF archive also has a member table, which is a list of
elements in the archive (you can get that by looking through the
linked list, but you have to read a lot more of the file). The
member table has a normal archive header with an empty name. It is
normally (and perhaps must be) the second to last entry in the
archive. The member table data is almost printable ASCII. It
starts with a 12 character decimal string which is the number of
entries in the table. For each entry it has a 12 character decimal
string which is the offset in the archive of that member. These
entries are followed by a series of null terminated strings which
are the member names for each entry.
Finally, an XCOFF archive has a global symbol table, which is what
we call the armap. The global symbol table has a normal archive
header with an empty name. It is normally (and perhaps must be)
the last entry in the archive. The contents start with a four byte
binary number which is the number of entries. This is followed by
a that many four byte binary numbers; each is the file offset of an
entry in the archive. These numbers are followed by a series of
null terminated strings, which are symbol names.
AIX 4.3 introduced a new archive format which can handle larger
files and also 32- and 64-bit objects in the same archive. The
things said above remain true except that there is now more than
one global symbol table. The one is used to index 32-bit objects,
the other for 64-bit objects.
The new archives (recognizable by the new ARMAG string) has larger
field lengths so that we cannot really share any code. Also we have
to take care that we are not generating the new form of archives
on AIX 4.2 or earlier systems. */
/* PR 21786: The PE/COFF standard does not require NUL termination for any of
the ASCII fields in the archive headers. So in order to be able to extract
numerical values we provide our own versions of strtol and strtoll which
take a maximum length as an additional parameter. Also - just to save space,
we omit the endptr return parameter, since we know that it is never used. */

/* Track file ranges occupied by elements. Add [START,END) to the
list of ranges and return TRUE if there is no overlap between the
new and any other element or the archive file header. This is
aimed at preventing infinite looping on malformed archives, for
"ar" and similar which typically use code like:
. for (last = bfd_openr_next_archived_file (archive, NULL);
. last;
. last = next)
. {
. do_something_with (last);
. next = bfd_openr_next_archived_file (archive, last);
. bfd_close (last);
. }
The check implemented here is only possible due to the fact that
for XCOFF archives bfd_openr_next_archived_file is the only code
path leading to _bfd_read_ar_hdr. _bfd_read_ar_hdr is not called
when reading the armap, nor do XCOFF archives use the extended name
scheme implemented in archive.c.
Note that the check relies on the previous element being closed,
and there is one case where add_range might fail but I think it is
sufficently unusual that it doesn't warrant fixing:
If the loop body above called bfd_openr_next_archived_file twice
with the same arguments and the element returned is bfd_close'd
between those calls then we'll return false here for the second
call. (For why this is so see _bfd_look_for_bfd_in_cache in
_bfd_get_elt_at_filepos, and know that bfd_close removes elements
from the cache.) */
