The changes to reorder sections for better relro protection on powerpc64,3e2b0f31,23283c1b, and5ad18f16, run into a problem with xlc. xlc -qdatalocal puts global variables into .toc, which means that .toc must be writable. The simplest way to accomplish this is to edit the linker script to remove .toc sections from .got on detecting xlc object files. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Add "object_in_toc". * elf64-ppc.c (ppc64_elf_add_symbol_hook): Assume that global symbols in .toc indicate xlc compiled code that might require a rw .toc. ld/ * emulparams/elf64ppc.sh (INITIAL_READWRITE_SECTIONS): Define. * emultempl/ppc64elf.em (params): Init new field. (ppc_after_open): New function. (LDEMUL_AFTER_OPEN): Define. * ldlang.c (lang_final): Whitespace fix. ld/testsuite/ * ld-powerpc/tocvar.d, * ld-powerpc/tocvar.s: New test. * ld-powerpc/tocnovar.d, * ld-powerpc/tocnovar.s: New test. * ld-powerpc/powerpc.exp: Run tocvar and tocnovar.
