Check GOTOFF reloc against protected data on x86 R_386_GOTOFF/R_X86_64_GOTOFF64 relocation shouldn't be used against protected data symbol on x86 since with copy relocation, address of protected data defined in the shared library may be external. This patch will break building shared libraries with protected data symbols using GCCs older than GCC 5 without the bug fix for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248 GCC backport request should be made in the GCC bug report above. bfd/ PR ld/pr17709 * elf32-i386.c (elf_i386_relocate_section): Also check R_386_GOTOFF against protected data symbol when building shared library. * elf64-x86-64.c (elf_x86_64_relocate_section): Also check R_X86_64_GOTOFF64 against protected data symbol when building shared library. ld/testsuite/ PR ld/pr17709 * ld-i386/protected6.d: New file. * ld-i386/protected6.s: Likewise. * ld-x86-64/protected6.d: Likewise. * ld-x86-64/protected6.s: Likewise. * ld-x86-64/protected7.d: Likewise. * ld-x86-64/protected7.s: Likewise. * ld-x86-64/protected7a.d: Likewise. * ld-x86-64/protected7b.d: Likewise. 2015-04-11 05:02:23 +08:00			`#as: --64`
