2014-09-12Test for overflow in eh_frame_hdr entries and for overlapping FDEsAlan Modra3-10/+50
With larger binaries on 64-bit systems, or indeed just binaries that have a large gap between text and data, it is possible for the .eh_frame_hdr lookup table entry values to overflow a signed 32-bit relative offset. It is also a requirement for the glibc FDE lookup code that only one FDE claim to cover any given address. * elf-bfd.h (struct eh_frame_array_ent): Add "range". * elf-eh-frame.c (_bfd_elf_write_section_eh_frame): Stash address range of FDEs to hdr_info->array. (_bfd_elf_write_section_eh_frame_hdr): Report overflow in .eh_frame_hdr entries, and overlapping FDEs.

2014-09-11Move ELF section headers to end of object fileAlan Modra4-19/+24
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..

2014-08-22Delete redundant struct cie fieldAlan Modra2-5/+8
cie->output_sec is used to when merging CIEs to ensure that only CIEs from the same output section are merged. I noticed an assignment to this field in _bfd_elf_parse_eh_frame, and thought "That's wrong, output_section isn't set properly when _bfd_elf_parse_eh_frame is called from gc-sections code". It turns out that this assignment is premature, and in fact a dead store. find_merged_cie overwrites with the correct value before the field is ever used. On looking a little more it becomes apparent that cie->cie_inf.u.cie.u.sec->output_section holds the same value, so cie->output_sec is redundant. * elf-eh-frame.c (struct cie): Delete "output_sec" field. (cie_eq, cie_compute_hash): Use output_section from cie_inf instead.
2014-08-22Index PowerPC64 linker generated .eh_frame in .eh_frame_hdrAlan Modra5-169/+190
I noticed recently that .eh_frame FDEs generated by the linker for call stubs and .glink weren't being indexed in .eh_frame_hdr, due to bfd_elf_discard_info being run before the linker generated .eh_frame sections were available for parsing. This patch moves code around in elf64-ppc.c and ppc64elf.em to avoid that problem. Another problem fixed here is that --gc-sections parses .eh_frame early, and the existing machinery allows only one go at parsing the .eh_frame sections. That resulted in the linker generated .eh_frame CIEs not being merged and no .eh_frame_hdr index entries for those FDEs. It turns out that all the info from parsing .eh_frame is attached to the section, so order of parsing isn't important, and after parsing sec_info_type being set will prevent a section being parsed again. At least, when parsing doesn't hit an error. So there isn't really any need for "parsed_eh_frame". "merge_cies" is also redundant, which means _bfd_elf_{begin,end}_eh_frame_parsing can also disappear. bfd/ * elf-bfd.h (struct eh_frame_hdr_info): Delete merge_cies and parsed_eh_frames.

At the moment it is possible to configure binutils for these triples but the resulting linker defaults to little endian with huge numbers of testsuite failures, which on the face of it does not appear to make much sense.
