   1439  1.1  christos 	     DLT-relative relocs against any local sym or global sym
   1440  1.1  christos 	     with DEF_REGULAR set, can be discarded.  At this point we
   1441  1.1  christos 	     have not seen all the input files, so it is possible that
   1442  1.1  christos 	     DEF_REGULAR is not set now but will be set later (it is
   1443  1.1  christos 	     never cleared).  We account for that possibility below by
   1444  1.1  christos 	     storing information in the dyn_relocs field of the

   1450  1.1  christos 
   1451  1.1  christos 	     As it turns out, all the relocs we will be creating here
   1452  1.1  christos 	     are absolute, so we cannot remove them on -Bsymbolic
   1453  1.1  christos 	     links or visibility changes anyway.  A STUB_REL reloc
   1454  1.1  christos 	     is absolute too, as in that case it is the reloc in the
   1455  1.1  christos 	     stub we will be creating, rather than copying the PCREL
   1456  1.1  christos 	     reloc in the branch.
   1457  1.1  christos 
   1458  1.1  christos 	     If on the other hand, we are creating an executable, we
   1459  1.1  christos 	     may need to keep relocations for symbols satisfied by a
