42*bf994817SAli Bahrami  * here:
43*bf994817SAli Bahrami  *
44*bf994817SAli Bahrami  * 1)	A Rel_desc descriptor for each relocation type, from which the
45*bf994817SAli Bahrami  *	rel_rtype field, and nothing else, is obtained. This is easily
46*bf994817SAli Bahrami  *	handled by constructing the necessary descriptors.
47*bf994817SAli Bahrami  *
48*bf994817SAli Bahrami  * 2)	A function, which called with the Rel_desc descriptor, returns
49*bf994817SAli Bahrami  *	a string representing the name of the symbol associated with
50*bf994817SAli Bahrami  *	the descriptor. The usual function for this is ld_reloc_sym_name().
51*bf994817SAli Bahrami  *	However, that function will not work in this case, as these synthetic
52*bf994817SAli Bahrami  *	relocations do not have an associated symbol. We supply the
53*bf994817SAli Bahrami  *	syn_rdesc_sym_name() function to simply return the fixed name.
