* elf32-ppc.c (ppc_elf_plt_type): New enumeration. (ppc_elf_link_hash_table): Replace old_got and new_got with plt_type and can_use_new_plt. (ppc_elf_create_dynamic_sections): Add SEC_HAS_CONTENTS, SEC_LOAD and SEC_READONLY to the VxWorks .plt flags. (ppc_elf_check_relocs): Set can_use_new_plt instead of new_plt. Move from plt_type == PLT_UNSET to PLT_OLD instead of setting old_plt. (ppc_elf_select_plt_layout): Move from plt_type == PLT_UNSET to either plt_type == PLT_OLD or plt_type == PLT_NEW. Assert that this function should not be called for VxWorks targets. (ppc_elf_tls_setup): Use plt_type instead of old_got. (allocate_got): Likewise. Rearrange so that max_before_header is only used for PLT_OLD and PLT_NEW. (allocate_dynrelocs): Use plt_type instead of old_got and is_vxworks. (ppc_elf_size_dynamic_sections): Likewise. (ppc_elf_relax_section): Likewise. (ppc_elf_relocate_section): Likewise. (ppc_elf_finish_dynamic_symbol): Likewise. (ppc_elf_vxworks_link_hash_table_create): Initialize plt_type. ld/ * emulparams/elf32ppccommon.sh: New file, extracted from... * emulparams/elf32ppc.sh: ...here. * emulparams/elf32ppcvxworks.sh: Include elf32ppccommon.sh instead of elf32ppc.sh. (BSS_PLT): Remove override. * Makefile.am (eelf32lppc.c): Depend on elf32ppccommons.h. (eelf32lppcnto.c, eelf32lppcsim.c, eelf32ppcnto.c): Likewise. (eelf32ppc.c, eelf32ppc_fbsd.c, eelf32ppcsimm): Likewise. (eelf32ppclinux.c): Likewise. (eelf32ppcvxworks.c): Likewise. Add missing vxworks.sh dependency. * Makefile.in: Regenerate. ld/testsuite/ * ld-powerpc/vxworks1-lib.s, ld-powerpc/vxworks1-lib.dd, * ld-powerpc/vxworks1-lib.rd, ld-powerpc/vxworks1.s, * ld-powerpc/vxworks1.dd, ld-powerpc/vxworks1.rd, * ld-powerpc/vxworks1.ld, ld-powerpc/vxworks1.sd: New test. * ld-powerpc/powerpc.exp: Run it.
