2014-12-04Add _bfd_elf_ifunc_get_synthetic_symtabH.J. Lu1-30/+71
In i386 and x86-64 binaries with ifunc, relocations against .got.plt section may not be in the same order as entries in PLT section. This patch adds _bfd_elf_ifunc_get_synthetic_symtab. It takes a function pointer which returns an array of PLT entry symbol values. It calls the function pointer to get the PLT entry symbol value array indexed by relocation index, instead of calling plt_sym_val on each relocation index.

2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu1-5/+33
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.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra1-1/+1
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.

We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value.
