2016-09-06Fix PR ld/20545 - relaxation bugs in avr backendSenthil Kumar Selvaraj2-7/+43
Prior to the patch, addends for relocs were being adjusted even if they went beyond an alignment boundary. This is wrong - to preserve alignment constraints, the relaxation logic adds as many padding bytes at the alignment boundary as was deleted, so addends beyond the boundary should not be adjusted. avr-prop-7.s reproduces this scenario. Also, prior to this patch, the relaxation logic assumed that the addr parameter pointed to the middle of the instruction to be deleted, and that addr - count would therefore be the shrinked instruction's address. This is true when actually shrinking instructions. The alignment constraints handling logic also invokes the same logic though, with addr as the starting offset of padding bytes and with count as the number of bytes to be deleted. Calculating the shrinked insn's address as addr - count is obviously wrong in this case - that offset would point to count bytes before the last non-padded byte. avr-prop-8.s reproduces this scenario. To fix scenario 1, the patch adds an additional check to ensure reloc addends aren't adjusted if they cross a shrink boundary. The shrink boundary is either the section size or an alignment boundary. Addends pointing at an alignment boundary don't need to be adjusted, as padding would occur and keep the boundary the same. Addends pointing at section size need to be adjusted though, as no padding occurs and the section size itself would get decremented. The patch records whether padding occured (did_pad) and uses that to detect and handle this condition. To fix scenario 2, the patch adds an additional parameter (delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish instruction bytes deletion from padding bytes deletion. It then uses that to correctly set shrinked_insn_address. bfd/ChangeLog: 2016-09-02 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/20545 * elf32-avr.c (elf32_avr_relax_delete_bytes): Add parameter delete_shrinks_insn.

2016-08-31PowerPC VLE sh_flags and p_flagsAlan Modra2-37/+56
ELF section sh_flags SHF_PPC_VLE was being set based on arch/mach, which meant all code sections in an object file has the flag or all lacked it. We can do better than that. Only those code sections where VLE is enabled ought to have the flag, allowing an object file to contain both VLE and non-VLE code. Also, ELF header p_flags PF_PPC_VLE wasn't being set, and segments were being split unnecessarily. bfd/ * elf32-ppc.c (ppc_elf_section_processing): Delete.

2016-08-19PowerPC64, Don't copy weak symbol dyn_relocs to weakdef.Alan Modra2-31/+77
At the cost of an extra field in the symbol table hash entries, this simplification to the relocate_section dynamic reloc test should help maintainability. * elf64-ppc.c (struct ppc_link_hash_entry): Add weakref. (ppc64_elf_copy_indirect_symbol): Set weakref. Don't merge dyn_relocs for weakdefs. (alias_readonly_dynrelocs): New function. (ppc64_elf_adjust_dynamic_symbol): Use alias_readonly_dynrelocs. (ppc64_elf_relocate_section): Simplify condition under which dyn_relocs are emitted.
2016-08-19PR 20472, PowerPC64 ifunc confusionAlan Modra2-65/+111
This patch fixes quite a lot of confusion in allocate_dynrelocs over ifuncs. Function descriptors make ELFv1 quite different to ELFv2. PR 20472 * elf64-ppc.c (ppc64_elf_before_check_relocs): Tweak abiversion test. (readonly_dynrelocs): Comment fix. (global_entry_stub): New function. (ppc64_elf_adjust_dynamic_symbol): Tweak abiversion test. Match ELFv2 code deciding on dynamic relocs vs. global entry stubs to that in size_global_entry_stubs, handling ifunc too. Delete dead weak sym code. (allocate_dynrelocs): Ensure dyn_relocs field is cleared when no dyn_relocs are needed. Correct handling of ifunc dyn_relocs. Tidy ELIMINATE_COPY_RELOCS code, only setting dynindx for undefweak syms. Expand and correct comments. (size_global_entry_stubs): Ensure symbol is defined. (ppc64_elf_relocate_section): Match condition under which dyn_relocs are emitted to that in allocate_dynrelocs.
