Replace DT_PPC_TLSOPT with DT_PPC_OPT.
This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality and more. This isn't backwards compatible, but the TLSOPT tag hasn't been used since the tls optimisation support was never submitted to glibc. /include/elf/ * ppc.h (DT_PPC_TLSOPT): Delete. (DT_PPC_OPT, PPC_OPT_TLS): Define. * ppc64.h (DT_PPC64_TLSOPT): Delete. (DT_PPC64_OPT, PPC64_OPT_TLS, PPC64_OPT_MULTI_TOC): Define. bfd/ * elf32-ppc.c (ppc_elf_size_dynamic_sections): Use new DT_PPC_OPT tag to specify tls optimisation. * elf64-ppc.c (ppc64_elf_size_dynamic_sections): Likewise. (ppc64_elf_finish_dynamic_sections): Specify whether multiple toc pointers are used via DT_PPC64_OPT. binutils/ * readelf.c (get_ppc_dynamic_type): Replace PPC_TLSOPT with PPC_OPT. (get_ppc64_dynamic_type): Replace PPC64_TLSOPT with PPC64_OPT.
