Documentation? This symbol does not appear in either llvm or binutils
sources. I presume this is on a development branch somewhere.
The comment is poor. Notice:
Noted. will do better.
case PT_LOPROC + 3:
if (ehdr->e_machine == EM_PPC64) {
break; /* DT_PPC64_OPT: integer bitmask */
the ppc64 comment describes the data payload.
As do the other comments beforehand.
