The Hurd-target porting work for binutils and gcc are sufficiently
different that I've decided we should address them in separate threads.

Those three files did indeed seem to be all that needed to be touched,
at least for the target concerns. (I haven't tried any native builds.
I presume that all the host-side issues just dtrt via autoconf feature tests.)
I believe I sent these same patches to Mark before, but I didn't post them
here. I was hoping for some comment from Mark, but haven't gotten any yet.
It's occurred to me that rather than adding GNU/Hurd targets for each CPU
that happen to be just the same as the GNU/Linux targets for the CPU, we
should more formally have in binutils a single GNU target for each CPU.
For each CPU, the canonical object format is ELF for both GNU/Linux and
GNU/Hurd, and I expect would be for any other GNU/some-kernel system. We
want to be compatible with whatever format quirks are used on that CPU with
GNU/Linux, because we will eventually be sharing binaries and in practice
already share GNU/Linux native tools as GNU/Hurd cross tools. (There are a
couple of CPUs for which the GNU/Linux binutils targets use slightly
different format details within ELF than what the "generic" ELF target for
that CPU uses. Whatever the reasons for the differences, the most
important tool and loader compatibility for us is with GNU/Linux). Aside
from native gdb, I think the only actual target OS dependencies in the
binutils/bfd world are a few places in the ld testsuite where it replicates
information that is actually part of the compiler target specs.
Moreover, I think this is the right way to think about targets in the tool
chain. That is, "GNU on CPU foobar" is a coherent target platform for
object files, in particular ELF and all the tools that work on it. Within
that, the "OS_ABI" PT_NOTE values and the DT_NEEDED sonames indicate
specific ABI dependencies that might be satisfied by any number of
different binary-compatible implementations.
In pragmatic terms, it is also by far the most convenient and least error
prone way I can think of to ensure that we wind up compatible with extant
GNU/Linux systems when we have new GNU/Hurd ports. The following patches
change all the `...-*-linux-gnu*' patterns into `...-*-gnu*' so that
they'll match CPU-VENDOR-linux-gnu as well as CPU-VENDOR-gnu. These
targets include support for some obsolete non-ELF formats once used on old
Linux systems, but it seems desireable to make it easy to operate from any
GNU system on all the file formats that anyone on any GNU system finds useful.
I'd like to get these changes put into binutils, and also have the binutils
maintainers made aware that any future GNU/Linux ports for new platforms
should be considered general GNU ports and use the broader target patterns.
Do you think this is a good plan? Do you think the binutils maintainers
will like it?
Thanks,
Roland
