Properly match PLT entry against .got.plt relocation Relocations against .got.plt section may not be in the same order as entries in PLT section. It is incorrect to assume that the Ith reloction index against .got.plt section always maps to the (I + 1)th entry in PLT section. This patch matches the .got.plt relocation offset/index in PLT entry against the index in .got.plt relocation table. It only checks R__JUMP_SLOT and R__IRELATIVE relocations. It ignores R__TLS_DESC and R__TLSDESC relocations since they have different PLT entries. bfd/ PR binutils/17154 * elf32-i386.c (elf_i386_plt_sym_val): Only match R__JUMP_SLOT and R__IRELATIVE relocation offset with PLT entry. * elf64-x86-64.c (elf_x86_64_plt_sym_val): Likewise.
