2014-08-30ppc476 patch area size miscalculationAlan Modra2-1/+5
ppc476 sections that end exactly on a page boundary need the workaround applied when a function ends in "bctr", or when pasting together code from multiple sections. The space allocated for the patch area didn't allow for this case, while the code in relocate_section performing the patches did, leading to an assertion failure. * elf32-ppc.c (ppc_elf_relax_section): Fix off by one error.

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.

2014-08-14configury changes to make ld plugin support controlled by --enable-pluginsAlan Modra3-32/+43
This also makes --enable-plugins default to on for hosts that can support plugins, so we have consistent lto toolchain support. The ACX_LARGEFILE moves aren't strictly necessary, but are harmless and will be necessary if plugin support is extended to more hosts via libtool's dlopen support.
