40bf994817SAli Bahrami  * This module uses do_reloc_ld() to execute several synthesized relocations.

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