+       * ppc64-tdep.c (ppc64_plt_entry_point): Rewrite to take TOC-relative
+       PLT offset, and retrieve r2 from stack when executing in reverse.
+       (ppc64_standard_linkage1_target): Drop pc param.  Calculate offset
+       rather than PLT address.
+       (ppc64_standard_linkage2_target): Likewise.
+       (ppc64_standard_linkage3_target): Likewise.
+       (ppc64_standard_linkage4_target): Likewise.
+       (ppc64_skip_trampoline_code_1): Adjust to suit.
