Here's what's to be done for maintaining GCC.

Apart from the target-specific configuration machinery, there shouldn't be any
major differences within GCC between the GNU/Hurd and GNU/Linux ports, for
example.  Especially all the compiler magic is all the same.

17f0f5acdcfb9181203ca9b6d8f8cbc64e5ce843 (2016-11-30).

<http://gcc.gnu.org/install/configure.html> has documentation for the
`configure` switches.

  * Configure fragments that have `*linux*` cases might/should often contain
    those for us (and GNU/k*BSD) as well.

      * `configure.ac`

      * `libstdc++-v3`

          * `configure.host`

            `abi_baseline_pair` etc. setting.  `config/abi/post/*-linux-gnu`.
            TODO.

          * `config/os/gnu-linux`

            Is used for all GNU systems, as per `configure.host`.  Should
            rename to `gnu-user` to reflect this?  TODO.

      * `gcc/acinclude.m4`:`gcc_GAS_FLAGS`: always pass `--32` to assembler for
        x86 Linux.  Probably we should just do the same, see `*-*-linux*`
        comment in [[!message-id "87zjrjcasc.fsf@schwinge.name"]].

      * `lib-prefix.m4` (present twice in GCC sources) contains one remaining
        `linux`-only case.

      * `libgcc`

          * `config/t-linux`
          * `config/i386/t-linux`

        TODO, rename to `t-gnu-user`.

          * `config/i386/linux-unwind.h`

        TODO, probably needs porting, if we need this.
        [[!GCC_PR 57851 desc="[patch] unwinding via signal trampoline for
        kfreebsd*-gnu"]].

    IRC, freenode, #hurd, 2014-01-10:

        <gnu_srs1> Hi, I assume gcc -fsplit-stack is not yet supported?
        <braunr> gnu_srs1:
          https://lists.gnu.org/archive/html/bug-hurd/2013-06/msg00100.html
        <gnu_srs1> braunr: That's exactly where the problem is:
          src/libgcc/generic-morestack.c:814:__morestack_load_mmap
        <gnu_srs1> no return value recorded
        <gnu_srs1> creating a call: page = mmap ((void*)0x0, 0, 4, 2, -1, 0);,
          returning EINVAL
        <braunr> lenght of 0 ?
        <gnu_srs1> yes, __morestack_current_segment, is zero
        <braunr> mmap is expected to return einval if the requested mapping has
          a size of 0 ..
        <braunr> i don't know what split stack is, but i remember it's a
          problem for the hurd
        <gnu_srs1> sorry, the address is zero from the above, and the length in
          the call is zero too
        <braunr> yes that's what i understood
        <braunr> and i'm telling you it's normal
        <braunr> the size is invalid
        <gnu_srs1> libgcc/generic-morestack.c:  mmap
          (__morestack_current_segment, 0, PROT_READ, MAP_ANONYMOUS, -1, 0);
        <braunr> well this is wrong
        <gnu_srs1> and the error code stays, not being reset in subsequent
          calls
        <gnu_srs1> causing an error later on
        <braunr> as roland says in
          https://lists.gnu.org/archive/html/bug-hurd/2013-06/msg00102.html, it
          should be possible to support split-stack now that we have tls
        <gnu_srs1> as thomas reported
        <braunr> i don't see the relation between split-stack and the mmap
          invocation
        <gnu_srs1> tls s in 2.17-97, right? that's the one I tried
        <braunr> tls is there, but not split stack support
        <braunr> and libpthread still has bugs related to changing the stack
          apparently
        <braunr> fixed upstream but not yet in debian packages
        <braunr> unless you want to try with the thread destruction packages
        <braunr> not sure it will change much though

      * Also see `libgcc/config/i386/morestack.S`: comments w.r.t
        `TARGET_THREAD_SPLIT_STACK_OFFSET`/`%gs:0x30` usage; likely needs
        porting.

      * As per `libgcc/config/i386/t-stack-i386`, the former file is only used
        for `-fsplit-stack` support -- which is currently enabled for us in
        `libgcc/config.host`.

      * `gcc/config/gnu-user.h` defines `*SPLIT_STACK*` macros -- which aren't
        valid for us (yet), I think.

      * Also see [[!sourceware_PR 10686]], glibc commit
        ecbf434213c0333d81706074e4d107ac45011635 `Reserve new TLS field for x86
        and x86_64` (`__private_ss`).

      * Might `-fsplit-stack` be useful for us with respect to our
        [[multithreaded|multithreading]] libraries?

        <gnu_srs> Hi, looks like __GLIBC__ is not defined by default for GNU?
        <gnu_srs> touch foo.h; cpp -dM foo.h|grep LIBC: empty
        <braunr> gnu_srs: well, this only tells your the compiler defaults
        <tschwinge> gnu_srs: See the email I just sent.

    [[!message-id "87396od3ej.fsf@schwinge.name"]]

        <braunr> __GLIBC__ would probably be introduced by a glibc header
        <gnu_srs> tschwinge: I saw your email. I wonder if features.h is
          included in the kFreeBSD build of webkit.
        <gnu_srs> It is defined in their build, but not in the Hurd build.
        <pinotree> gcc on kfreebsd unconditionally defines __GLIBC__
        <pinotree> (a bit stupid choice imho, but hardly something that could
          be changed now...)
        <braunr> :/
        <braunr> personally i don't consider this only "a bit" stupid, as
          kfreebsd is one of the various efforts pushing towards portability
        <braunr> and using such hacks actually hinders portability ...
        <pinotree> yeah don't tell me, i can remember at least half dozen of
          occasions when a code wouldn't have been compiling at all on other
          glibc platforms otherwise
        <pinotree> sure, i have nothing against kfreebsd's efforts, but making
          gcc define something which is proper of the libc used is stupid
        <braunr> it is
        <pinotree> i spotted changes like:
        <pinotree> -#ifdef __linux
        <pinotree> +#if defined(__linux__) || defined(__GLIBC__)
        <pinotree> and wondered why they wouldn't work at all for us... and
          then realized there were no #include in that file before that
          preprocessor check
        <tschwinge> This is even in upstream GCC gcc/config/kfreebsd-gnu.h:

        <tschwinge>   while (0)
        <tschwinge> I might raise this upstream at some point.
        <pinotree> tschwinge: i could guess the change was proposed by the
          kfreebsd people, so asking them before at d-bsd@d.o would be a start
        <tschwinge> pinotree: Ack.
        <pinotree> especially that they would need to fix stuff afterwards
        <pinotree> imho we could propose them the change, and if they agree put
          that as local patch to debian's gcc4.6/.7 after wheezy, so there is
          plenty of time for them to fix stuff

          for kFreeBSD.

    Before being temporarily reverted in commit
    294528f77a8097ace2986019770cad097a3bbc55, it had originally been added in
    commit a55668c45867980a07a06690a45edd43b4c82efa `Add -mgeneral-regs-only
    option`:

        X86 Linux kernel is compiled only with integer instructions.  Currently,
        
        -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -mno-80387
        -mno-fp-ret-in-387  -mskip-rax-setup
        
        is used to compile kernel.  If we add another non-integer feature, it
        has to be turned off.  We can add a -mgeneral-regs-only option, similar
        to AArch64, to disable all non-integer features so that kernel doesn't
        need a long list and the same option will work for future compilers.
        It can also be used to compile interrupt handler.

    Will this be useful for GNU Mach, too?

Here's a log of a GCC build run; this is from Git commit

plus *GNU Hurd Ada fixes*,
plus *libstdc++ RLIMIT changes* ([[!message-id

and laplace.SCHWINGE.

Different hosts may default to different shells and compiler versions; thus
harmonized.
`--disable-libcilkrts`,
`--disable-libmpx`,
`--disable-libsanitizer`,
`--disable-libvtv`,
until these is auto-detected/fixed/ported for GNU Hurd.
`--with-native-system-header-dir=/usr/include` because GCC still defaults to
`/include` for GNU Hurd.  Explicit `--enable-multiarch` because *auto check [is
disabled if] configured with --native-system-header-dir*.

This takes up around 4.6 GiB, and runs for [[5 h 16 min|performance#measure]]
on kepler.SCHWINGE and [[5 h 14 min|performance#measure]] on laplace.SCHWINGE.

# Install

    [...]

This takes up around 1.3 GiB, and runs for [[1 min|performance#measure]] on
kepler.SCHWINGE and [[5 min|performance#measure]] on laplace.SCHWINGE.


## Analysis

    $ toolchain/logs/process gcc install

  * `libtool: finish`: `ldconfig` is not run for the Hurd.

    [[libtool]].


# Testsuite

<http://gcc.gnu.org/install/test.html>

    $ make -k check 2>&1 | tee log_test
    [...]

This runs for [[6 h 12 min|performance#measure]] on kepler.SCHWINGE and [[13 h
34 min|performance#measure]] on laplace.SCHWINGE.


## Analysis

  A lot of the failures are due to gcc's unwind support not knowing about signal trampoline on GNU/Hurd, this is a TODO.

    that the failing Ada test disturbs the PTY, and that affect later
    runtest/expect runs, as also seen in GDB testing.

            dpkg: dependency problems prevent configuration of libc0.3:hurd-i386:
             hurd (1:0.6.git20151012-1) breaks libc0.3 (<< 2.19-15~) and is installed.
              Version of libc0.3:hurd-i386 to be configured is 2.19-11~.

    With these packages installed, and rebooted, the two tests fail with a
    segmentation fault, which -- given that we presumable have not implemented
    the *support code for unwinding through signal frames* -- probably is the
    result to be expected.

    Generally, it's always either none or both tests that hang.  If they hang,
    and you try to C-c them, that doesn't work.  If you kill -KILL them from
    another terminal, they do get killed.  In this case, then there's strange
    things going on if the (pseudo) terminals are re-used later on: hangs,
    dropped characters.  (This sounds familiar from GDB testsuite runs.)

        [hangs]

    System shutdown/reboot hangs when trying to terminate all running
    processes; luckily, I still had a shell open, and after `kill -KILL`ing the
    `stack_check1.exe` process, the shutdown/reboot proceeds.

    Restore previous 1:0.6.git20150704-2 packages.

### Distributed Testing


#### IRC, OFTC, #gcc, 2012-05-31

    <dnovillo> jsm28: in your mentor testing, you have the source and build
      tree available for make check?  or it's a pure installed-tree test?
    <jsm28> dnovillo: Source tree, install tree, no build tree.
    <dnovillo> jsm28: so, you run make check on top of the source tree or copy
      the */testsuite trees to a testing area?
    <jsm28> Create a site.exp and do runtest in a temporary directory.  runtest
      is pointed to the source tree to find sources.
    <jsm28> For cross testing for GNU/Linux targets, the temporary directory is
      mounted at the same path on host and target.
    <dnovillo> jsm28: thanks.  i guess i'll have to find the slice of the
      source tree i need to copy.
    <dnovillo> jsm28: for libstdc++ do you write a different site.exp? 
    <dnovillo> i noticed that it generates a different site,exp there.
    <jsm28> The site.exp is mostly the same for all testsuites (so includes
      settings that only some testsuites use).
    <dnovillo> ok, thanks.
    <dnovillo> and when you say "pointed to the source tree" you mean "set
      srcdir /path/to/top/of/gcc" ?
    <dnovillo> (in site.exp)
    <jsm28> The GDB testsuite requires that you run the GDB testsuite's
      configure script in the temporary directory where you will run runtest.
      I don't think any GCC testsuites we use have requirements like that.
    <jsm28> dnovillo: --srcdir option to runtest.
    <dnovillo> ah, yes.
    <jsm28> (and --tool, --target_board etc.)
    <dnovillo> right
    <dnovillo> since i'm distributing the tests. i want each node to only do a
      bunch of files.  this means that i either use 'tool.exp=file-pattern' or
      simply copy the subset of files i want tool.exp to find.
    <dnovillo> i chose the second approach, but that breaks in a handful of
      cases that need files from other sub-directories.
    <dnovillo> like g++.dg gcc.dg using stuff from c-c++-common.
    <dnovillo> for libstdc++, the possibilities for splitting are enormous as
      it has many directories.
    <dnovillo> but i'm not setting it right.  runtest runs without even trying
      to test anything.
    <dnovillo> i'm not having it pick up the right driver.
    <jsm28> Probably all .exp files should be copied to anywhere running
      testsuites, since some read .exp files from other directories.
    <dnovillo> jsm28: that could be it too.  it's irritating that libstdc++
      does not even error out.  runtest just does nothing and returns 0.

##### IRC, OFTC, #gcc, 2012-06-06

    <dnovillo> any libstdc++ maintainer around?
    <dnovillo> or, does anyone know when the testsuite/data files are copied
      into the running testsuite/ dir?
    <dnovillo> seems to be done in advance by make.
