================
Comment at: ELF/Arch/PPC64.cpp:122-125
+// Loading a symbol address from .toc (e.g. "addis r,2,foo at toc@ha;
+// ld r,foo at toc@l(r)") can be relaxed to compute the address using an offset
+// relative to the toc pointer (e.g. "addis r,2,offset; addi r,r,offset" or
+// "nop; addi r,2,offset").
