2014-09-11Move ELF section headers to end of object fileAlan Modra31-42/+76
Currently, section ordering differs a little for non-loaded reloc sections output by ld -emit-relocs or ld -r and that after passing such objects through objcopy. Not that it really matters, but it would be better for a simple objcopy to produce an unchanged output object file. Also, section headers are put somewhere in the middle of the non-loaded sections, again slightly differently for ld and objcopy. This patch fixes these discrepancies and puts section headers last, which is where gold puts them, and is where bfd_from_remote_memory wrongly assumed they will be found. bfd/ * elf.c (assign_file_positions_except_relocs): Move section header placement to..

2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu9-5/+218
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.

Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have no normal symbols, except things like __gnu_lto_slim.

2014-04-15[AArch64] Fix off by one error in instruction relaxation mask.Marcus Shawcroft2-1/+6
The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to ensure that destination register in a relaxed ldr instruction is always X0. The mask has an off by one error resulting in the most significant bit of the destination register being retained in the relaxed instruction. The issue generally appears when the compiler emits TLS accesses code under high register pressure resulting in a broken code sequence.
