2013-11-11Correct elf64-ppc.c handling of protected symbolsAlan Modra2-14/+21
Some places in elf64-ppc.c carelessly used SYMBOL_CALLS_LOCAL when the proper test is SYMBOL_REFERENCES_LOCAL for cases where we take the address of a protected symbol. This works OK for function descriptors but not for ELFv2. Setting symbols to their global entry stub a little earlier is to ensure _bfd_elf_hash_symbol allows such symbols in .gnu.hash. * elf64-ppc.c (ppc64_elf_edit_toc): Use SYMBOL_REFERENCES_LOCAL here, not SYMBOL_CALLS_LOCAL.

2013-11-02Simplify ppc64 code setting toc_off.Alan Modra2-35/+23
Every function has a nominal toc pointer value, even if it isn't used, so set toc_off for every code section to the value used in that object file. The thinking here was that if a code section didn't use the toc it could use the previous object file's toc pointer value. It can, but doing so is only a gain if functions in that section are called mostly from previous objects sharing the same toc. We lose if the functions in question are called mostly from the current object or following objects, and it's a good bet they will probably mostly be called from the current object. * elf64-ppc.c (ppc64_elf_next_input_section): Always set toc_off to value for object file.

2013-10-30Report overflow on PowerPC64 @h and @ha relocations.Alan Modra5-32/+191
This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.

2013-10-29ld/ELF: refine fake STT_FILE symbol emissionJan Beulich2-16/+25
There's no real need to emit these always: They're needed only if we indeed want to emit a localized symbol. Hence defer emission until we at least did the basic early checks that would lead to no such symbol getting emitted. This in particular avoids emitting such a symbol in the majority of (if not all) "ld -r" cases. I hope my set of cross build tests caught all the test cases needing adjustment - please forgive if I missed a few. bfd/ 2013-10-29 Jan Beulich <jbeulich@suse.com> * elflink.c (struct elf_outext_info): Add field file_sym_done.
