[[!tag open_issue_binutils]]

Here's what's to be done for maintaining GNU Binutils.

As these tools primarily deal with low-level parts of the target architecture
and the object file format (ELF ABI), which are essentially (at least meant to
be) the same, there shouldn't be many differences comparing the binutils
between the GNU/Hurd and GNU/Linux ports, for example.  There are a few,
though, as explained below.

  * Globally

      * a.out, COFF, PE image support and 64 bit support are not interesting.

      * In the [[testsuite]]s, `.exp` and `.d` files very likely should not
        only
        care for `*-*-linux*`, but also `*-*-gnu*`.  (If the need to be
        conditionalized like this at all.)

  * `bfd/`

      * `config.bfd`

          * `i[3-7]86-*-gnu*`

            Comparing to `i[3-7]86-*-linux-*`:

              * `i386linux_vec` -- a.out.

              * `i386pei_vec` -- PE.

              * 64 bit.

      * `configure.host`

        Souldn't need anything.  x86 Linux neither.

      * `configure.in`

        Linux:

          * `COREFILE=trad-core.lo` with `TRAD_HEADER='"hosts/i386linux.h"'`

            We don't have any such core file support configured.  TODO: should
            we?  Where is this core file reading exactly used?  GDB?

          * `i386linux_vec` -- a.out.

          * `i386pei_vec` -- PE.

  * `binutils/`

      * `configure.tgt`

  * `gas/`

      * `config/te-gnu.h`

        C.f. `te-linux.h`; search tree for `TE_LINUX` vs. `TE_GNU` usage.

          * `tc-i386.h`

            Sole `TE_LINUX` usage is for a.out.

      * `configure.tgt`

  * `ld/`

     * `configure.host`

         * `*-*-gnu*`

            TODO: resolve `crt0.o` vs. `crt1.o` issue.  [[Testsuite
            failures|testsuite#static]].

      * `configure.tgt`

          * `i[3-7]86-*-gnu*`

            Compare to `i[3-7]86-*-linux-*`, but don't need a.out (`i386linux`)
            and 64 bit support.
