* elf64-ppc.c (ppc64_elf_check_relocs): Don't refcount tlsld_got here.. (ppc64_elf_gc_sweep_hook): ..or here.. (ppc64_elf_tls_optimize): ..or here. Make two passes through the relocs, ensuring that tls_get_addr calls follow gd and ld relocs. (allocate_dynrelocs): Refcount tlsld_got here. (ppc64_elf_size_dynamic_sections): Allocate local got and call allocate_dynrelocs before allocating tlsld_got. (ppc64_elf_relocate_section): Remove check that a tls_get_addr call follows gd and ld relocs. ld/testsuite/ * ld-powerpc/tlsso.d: Update for changed got alloc order. * ld-powerpc/tlsso.r: Likewise.
