      BFD_INIT_MAGIC · bf2dd8d7
      Alan Modra authored
      This patch performs a run-time test that a shared libbfd.so has been
      compiled with the same size bfd_vma as that of apps using the library.
      On a 32-bit host it is easily possible to have one libbfd.so compiled
      to support 64-bit targets (or configured with --enable-64-bit-bfd)
      while another only supports 32-bit targets.  The two libraries will
      have differently sized bfd_vma types, and if the wrong one is loaded
      all sorts of weird behaviour might be seen.

      Prevent the --keep-global-symbol and --globalize-symbol options from being used together. · de564eb5
      Nick Clifton authored
      This is the result of an email thread starting here:
      The main point of the thread is this observation:
        * Supposing we had an object file with two globals, SomeGlobal and
        SomeOtherGlobal, if one were to do "--globalize-symbol SomeGlobal
        --keep-global-symbol SomeOtherGlobal", you might expect that both
        SomeGlobal and SomeOtherGlobal are global in the output file... but it
        isn't. Because --keep-global-symbol is set and doesn't include
        SomeGlobal, SomeGlobal will be demoted to a local symbol. And because
        the check to see if we should apply the --globalize-symbol flag checks
        "flags" (the original flag set), and not "sym->flags", it decides not
        to do anything, so SomeGlobal remains a local symbol. Although this is
        a weird edge case, should this be changed so that --keep-global-symbol
        implicitly keeps anything also specified via --globalize-symbol? (The
        code seems technically correct with respect to the documentation, but
        IMO the behavior is counter-intuitive).
      binutils* objcopy.c (copy_main): Issue a fata error if the
      	--keep-global-symbol(s) and the --globalize-symbol(s) options are
      	used together.

      PR23611, objcopy is not removing executable relocatable sections · f9853190
      Alan Modra authored
      BFD handles ELF relocation sections in an executable differently to
      relocation sections in a relocatable object.  For a relocatable
      object, BFD carries the relocations as data associated with the
      section to which they apply; The relocation section doesn't appear as
      a separate section.  For an executable, dynamic relocation sections do
      appear as separate sections.  This means that objcopy needs to use
      different strategies when dealing with relocations.
      When --remove-relocations was added to objcopy with commit
      d3e5f6c8, objcopy lost the ability to remove dynamic relocation
      sections such as .rela.plt from executables using the option
      "--remove-section=.rela.plt".  This patch reinstates that
      I thought it best to keep --remove-relocations as is, rather than
      extending to handle dynamic relocations as per the patch in the PR,
      because executables linked with --emit-relocs may have both dynamic
      and non-dynamic relocations.  In that case --remove-relocataions=* is
      useful to remove all the non-dynamic relocations.
      	PR binutils/23611
      	* objcopy.c (handle_remove_section_option): Consider .rela and
      	.rel sections for stripping directly as well as attached to the
      	associated section they relocate.
      	* doc/binutils.texi (remove-relocations): Specify that this
      	option removes non-dynamic relocation sections.
      	* testsuite/binutils-all/objcopy.exp
      	(objcopy_remove_relocations_from_executable): New test.

      Add support for v3 binary annotation notes. · 6f156d7a
      Nick Clifton authored
        I am checking in the attached patch which updates the binutils
        support for version 3 binary annotation notes.  (Version 3 adds
        an end address to the ranges covered by the notes, so that it
        is possible to detect gaps in the coverage).
        This patch also stops the note merging feature of objcopy from
        executing if the notes have relocations against them.  This makes the
        code simpler, and prevents the problems with architectures which have
        unusual relocation management issues.

      Fix stripping relocs in a file with mergeable notes. · 2d054e6b
      Nick Clifton authored
        A recent Fedora bug (1520805) exposed a problem with objcopy's reloc
        copying code, when a binary also contains mergeable notes.  The note
        merging code would delete some relocs, but then the reloc copying code
        would try to put them back again, which did not work.
        So I am checking in the patch below to fix the problem.  The patch
        also tweaks one of the binutils note merging tests so that it is
        skipped for the Sparc64 target, since this has funky relocs.
      binutils	* objcopy.c (copy_relocations_in_section): Use the orelocations
      	field of the input section, if it has been initialised.
      	* testsuite/binutils-all/note-2-64.d: Skip test on Sparc64.
      bfd	* elfcode.h (elf_write_relocs): Check for an empty howto field.

      binutils: remove sparc64/mips64 workaround in objcopy build notes merge code · b4f5b984
      Jose E. Marchesi authored
      This patch removes a workaround recently installed in objcopy that
      avoided removing duplicated notes in targets for which the number of
      internal relocations may be bigger than the number of external
      relocations.  With the recent fixes in sparc64 and mips64, this
      workaround is no longer necessary.

      bfd: Rename Chunk and S3Forced · 4bc26c69
      Pedro Alves authored
      The direct references in objcopy kind of look like a hack to me, so
      I'm calling these symbols internal too.  Certainly they aren't named
      and documented as a public BFD symbol today anyway.
      So ... give these bfd-internal symbols with external linkage a _bfd_
      prefix to avoid collisions in the global symbol namespace.
      While at it, give them names that more closely match the corresponding
      option name that toggles them.
      Also while at it, fix a few related comment typos.
