In particular, R_X86_64_64, R_X86_64_DTPOFF64, and 8570af302Sopenharmony_ci * R_X86_64_TPOFF64 may need checking. */ 9570af302Sopenharmony_ci 10570af302Sopenharmony_ci/* The R_X86_64_64, R_X86_64_DTPOFF32, and R_X86_64_TPOFF32 reloc types 11570af302Sopenharmony_ci * were previously mapped in the switch table form of this file; however, 12570af302Sopenharmony_ci * they do not seem to be used/usable for anything.
