x86-64: Restore PIC check for PCREL reloc against protected symbol commit bd7ab16b4537788ad53521c45469a1bdae84ad4a Author: H.J. Lu <hjl.tools@gmail.com> Date: Tue Feb 13 07:34:22 2018 -0800 x86-64: Generate branch with PLT32 relocation removed check R_X86_64_PC32 relocation against protected symbols in shared objects. Since elf_x86_64_check_relocs is called after we have seen all input files, we can check for PC-relative relocations in elf_x86_64_check_relocs. We should not allow PC-relative relocations against protected symbols since address of protected function and location of protected data may not be in the shared object. bfd/ PR ld/24151 * elf64-x86-64.c (elf_x86_64_need_pic): Check SYMBOL_DEFINED_NON_SHARED_P instead of def_regular. (elf_x86_64_relocate_section): Move PIC check for PC-relative relocations to ... (elf_x86_64_check_relocs): Here. (elf_x86_64_finish_dynamic_symbol): Use SYMBOL_DEFINED_NON_SHARED_P to check if a symbol is defined in a non-shared object. * elfxx-x86.h (SYMBOL_DEFINED_NON_SHARED_P): New. ld/ PR ld/24151 * testsuite/ld-x86-64/pr24151a-x32.d: New file. * testsuite/ld-x86-64/pr24151a.d: Likewise. * testsuite/ld-x86-64/pr24151a.s: Likewise. * testsuite/ld-x86-64/x86-64.exp: Run pr24151a and pr24151a-x32. 2019-02-06 10:45:23 +08:00			`#source: pr24151a.s`
