PowerPC64 treatment of absolute symbols
Supporting -static-pie on PowerPC64 requires the linker to properly treat SHN_ABS symbols for cases like glibc's _nl_current_LC_CTYPE_used absolute symbol. I've been slow to fix the linker on powerpc because there is some chance that this will break some shared libraries or PIEs. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Consolidate local sym handling code. Don't count dyn relocs against non-dynamic absolute symbols. (dec_dynrel_count): Adjust to suit. (ppc64_elf_edit_toc): Don't remove entries for absolute symbols when pic. (allocate_got): Don't allocate space for got relocs against non-dynamic absolute syms. (ppc64_elf_layout_multitoc): Likewise. (got_and_plt_relr): Likewise. (ppc64_elf_size_dynamic_sections): Likewise for local got. (got_and_plt_relr_for_local_syms): Likewise. (ppc64_elf_size_stubs): Don't allocate space for relr either. (ppc64_elf_relocate_section): Don't write relocs against non-dynamic absolute symbols. Don't optimise got and toc code sequences loading absolute symbol entries. ld/ * testsuite/ld-powerpc/abs-reloc.s, * testsuite/ld-powerpc/abs-static.d, * testsuite/ld-powerpc/abs-static.r, * testsuite/ld-powerpc/abs-pie.d, * testsuite/ld-powerpc/abs-pie.r, * testsuite/ld-powerpc/abs-shared.d, * testsuite/ld-powerpc/abs-shared.r, * testsuite/ld-powerpc/abs-pie-relr.d, * testsuite/ld-powerpc/abs-pie-relr.r, * testsuite/ld-powerpc/abs-shared-relr.d, * testsuite/ld-powerpc/abs-shared-relr.r: New tests. * testsuite/ld-powerpc/powerpc.exp: Run them.
