[PATCH, Modula-2 (C/C++/D/F/Go/Jit)] (Register spec fn) (v2)

[Gaius Mulley]

[-- Attachment #1: Type: text/plain, Size: 19776 bytes --]


Hello,

here is version two of the patches which introduce Modula-2 into the
GCC trunk.  The patches include:

  (*)  a patch to allow all front ends to register a lang spec function.
       (included are patches for all front ends to provide an empty
        callback function).
  (*)  patch diffs to allow the Modula-2 front end driver to be
       built using GCC Makefile and friends.

The compressed tarball includes:

  (*)  gcc/m2  (compiler driver and lang-spec stuff for Modula-2).
       Including the need for registering lang spec functions.
  (*)  gcc/testsuite/gm2  (a Modula-2 dejagnu test to ensure that
       the gm2 driver is built and can understands --version).

These patches have been re-written after taking on board the comments
found in this thread:

   https://gcc.gnu.org/ml/gcc-patches/2013-11/msg02620.html

it is a revised patch set from:

   https://gcc.gnu.org/ml/gcc-patches/2019-06/msg00220.html

I've run make bootstrap and run the regression tests on trunk and no
extra failures occur for all languages touched in the ChangeLog.

I'm currently tracking gcc trunk and gcc-9 with gm2 (which works well
with amd64/arm64/i386) - these patches are currently simply for the
driver to minimise the patch size.  There are also > 1800 tests in a
dejagnu testsuite for gm2 which can be included at some future time.

Here are the proposed patches and ChangeLogs and new files (gm2-v2.tar.gz)
(after the patches):

Echoing a point Joseph made there: does this approach to linking work
with LTO, especially given the auto-generated main module?

I don't think that should hold up the patch, just curious.

It looks like the current GCC driver code is a bit of a half-transition
towards a more C++ way of doing things.  If we were going to embrace
that fully, I guess each frontend driver would get the opportunity
to subclass "driver" and override functions where appropriate.  It then
wouldn't be necessary to add each new hook to every frontend driver
(and force other out-of-tree frontends to do the same).

But that isn't how things work now, and going down that particular
rabbit hole shouldn't be a requirement for this patch.  So IMO the
approach you're taking is fine.

The same goes for the new functions that you're exporting.  Ideally
they'd be (protected?) member functions of "driver", but the internal
callers are at points where the driver object is no longer to hand.
Again, exposing functions follows existing practice so IMO is fine.

Sorry for the changelog nits, but:

Should be: 2019-06-14
Should only be two spaces between your name and email address.
(Not that I care, I just work here :-))

Lines should be indented to under the "*" rather than two spaces beyond.

Missing newline before "GM2".  Looks like some of the Makefile.def
entries belong in Makefile.tpl instead.  E.g. GM2_FOR_BUILD is only
mentioned in Makefile.tpl.

Reordering things slightly...

This would be simpler if you make lang_spec_functions a vec<spec_function>.

It'd be simpler to expose save_switch and handle_OPT_B directly rather
than use wrappers.  The "fe_" prefix isn't used for other public functions.

Formatting, should be:

static void
handle_OPT_B (const char *arg)

(although I guess no longer static after the above).

AFAICT this is only used here:

------------------------------------------------------------------------
/* no_objects return an empty string, but also remove all objects
   from the command line.  */

extern void fe_remove_infile (const char *);

static const char *
no_objects (int argc ATTRIBUTE_UNUSED, const char *argv[] ATTRIBUTE_UNUSED)
{
  object_list *o;

  for (o = head_objects; o != NULL; o = o->next)
    fe_remove_infile (o->name);

  return NULL;
}
------------------------------------------------------------------------

which looks unnecessarily quadratic.  Is there a simpler way to do this?

Either way, the name fe_remove_infile seems inconsistent with the
comment and with what the code actually does.

Heh, the (existing) F77 comments look a bit of out of date :-)

Some comments about the tar file (wasn't sure whether this was part
of the submission yet, or whether you were just including it because
of Joseph's request in the earlier thread):

All in-tree configure files are now called configure.ac, so it would be
good if gm2 did the same.

------------------------------------------------------------------------
AC_INIT(gm2config.h.in, 1.9.1, gm2@nongnu.org)
------------------------------------------------------------------------

Would this stay the same after the merge, or would the Savannah version
of gm2 no longer be maintained?

------------------------------------------------------------------------
#ifndef MATH_LIBRARY_PROFILE
#define MATH_LIBRARY_PROFILE MATH_LIBRARY
#endif

#ifndef LIBSTDCXX
#define LIBSTDCXX "stdc++"
#endif

#ifndef LIBSTDCXX_PROFILE
#define LIBSTDCXX_PROFILE LIBSTDCXX
#endif

#ifndef LIBSTDCXX_STATIC
#define LIBSTDCXX_STATIC NULL
#endif
------------------------------------------------------------------------

These macros in gm2spec.c don't seem to be used.  "stdc++" in particular
is hard-coded further down.

------------------------------------------------------------------------
/* assert, a simple assertion function.  */

static void
assert (int b)
{
  if (!b)
    {
      printf ("assert failed in gm2spec.c");
      exit (1);
    }
}
------------------------------------------------------------------------

Better to use gcc_assert.

------------------------------------------------------------------------
#if defined(DEBUGGING)
static void
printOption (const char *desc, struct cl_decoded_option **in_decoded_options,
             int i)

Realise it's only a debugging function, but should be print_option.

------------------------------------------------------------------------
/* The last entry in libraryName must be the longest string in the
list.  This is the -flibs=name.  */
static const char *libraryName[maxlib]
    = { "iso", "pim", "ulm", "min", "log", "cor" };
------------------------------------------------------------------------

Some comments like this aren't properly indented (but most are).
Mind having a quick scan and fix?  Realise it'll be a bit tedious, sorry.

Why does the last entry need to be the longest?  It only seems to be
used in a strcmp loop, and the list is separated by commas.

The corresponding option documentation says:

------------------------------------------------------------------------
flibs=
Modula-2 Joined
specify the library order, currently legal entries include: logitech, min, pim-coroutine, ulm, iso
------------------------------------------------------------------------

but it sounds like the actual values are: log, min, pim, ulm and iso,
is that right?  Would be worth clarifying the documentation line if so.

------------------------------------------------------------------------
/* get_archive_name, return the corresponding archive name given the library

    if (strcmp (libraryName[i], library) == 0)
      return archiveName[i];
  return NULL;
}

/* build_archive, returns a string containing the a path to the
   archive defined by, libpath, s, and, dialectLib.  */

static char *
build_archive (const char *library)

    {
      const char *a = get_archive_name (library);
      if (a != NULL)
        {
          char *s = (char *)xmalloc (strlen (a) + 1);
          strcpy (s, a);
          return s;
        }
    }
  return NULL;
}
------------------------------------------------------------------------

The comment above build_archive seems to be a bit mangled.

It looks like this code silently ignores unrecognised -flibs= options.
Is that the intended behaviour?  I couldn't see where the valid values
were enforced.

------------------------------------------------------------------------
  else if (gm2_prefix != NULL && !seen_fmakeall0)

    /* no need to issue a warning if seen_fmakeall0 as the parent will
    have set COMPILER_PATH and LIBRARY_PATH because of GM2_ROOT and users
    should not be using -fmakeall0 as it is an internal option.  */
    fprintf (stderr,
             "warning it is not advisible to set " GM2_PREFIX_ENV
             " as well as either " LIBRARY_PATH_ENV " or COMPILER_PATH\n");
------------------------------------------------------------------------

This should be a proper warning, using the diagnostic machinery.

Posting the tar file definitely helped to show how these things are used.
But one thing I'm still not sure about is why gm2 needs it's own -B-related
code, and why for example it needs:

------------------------------------------------------------------------
/* find_executable_path, if argv0 references an executable filename
   then use this path.  */

static const char *
find_executable_path (const char *argv0)
{
  if (access (argv0, X_OK) == 0)
    {
      const char *n = strrchr (argv0, DIR_SEPARATOR);

      /* strip off the program name from argv0, but leave the DIR_SEPARATOR. */
      if (n != NULL)
        {
          char *copy = xstrdup (argv0);
          char *n = strrchr (copy, DIR_SEPARATOR);
          n[1] = (char)0;
          return copy;
        }
    }
  return NULL;
}
------------------------------------------------------------------------

GCC supports a lot of (maybe too many?) different installation layouts,
so it would be good to reuse the existing search code and self-relocation
code if at all possible.  That might mean exposing more functions to the
frontend driver, but IMO that'd still be preferable.

Thanks,
Richard

I know we have multiple driver binaries but at the same time we support -x language. How will this continue to work with lang spec files when not integrating all FE drivers into one?

I built on pwoerpc64-linux, with the patch and the tarball.

I first need this patch, because srcdir is an absolute path for me:

(This patch might not be correct, but it works for me to get things to
build, at least).

But then I still get build failures: it tries to run xgcc when it hasn't
been built yet.  ("it" == "something", I didn't keep logs, sorry).

I let it run overnight with -j1, and it finished.  The testsuite is
running now :-)

Hi Richard,

many thanks for taking the time to review the patches and tarball.

I'm in the process of altering the ar and ranlib to gcc-ar/gcc-ranlib
and I'll test the -flto within gm2.  I think it should work - as gm2
utilises gcc to perform the final link and passes .o and .a files as
appropriate.  [Just finished testing and indeed it works - I need to
substitute ar and ranlib with their gcc-ar and gcc-ranlib counterparts].

sounds interesting - I guess this could result in a single driver binary
which could also make for a unified gcc?

yes all possible I imagine.

no problem - I'll adjust to the house convention.

will correct the documentation.  The libraries are log, min, pim, ulm,
iso and cor.  The last entry being the longest is no longer true - will
cull that comment.

yes true - I'll rewrite it.

yes it doesn't enforce them - I thought it would allow for 3rd party
libraries to be added alongside the gcc install.  But I guess it could
still check the directory names inside the install area if required.

this was to allow users to have multiple versions installed (a while
back).  I suspect it is time to cull this code (at least) and re-examine
the current installation support routines and use them instead - as you
mention.

Hi Segher,

many thanks for the patch and highlighting the relative vs absolute
srcdir build.  I've fixed the makeversion with a change to the script
(directory option added).  I'll work on the configure line and explore a
solution.  Yes -j1 is definitely an overnight task!

I meant to give a build with gm2 included a try on Solaris, but ended up
pretty much confused:

* I've started with the gm2 repo on savannah.  Running the combine-trees
  script on master tried to combine gm2 with gcc 4.7.4.  Trying again
  with configure --with-gcc=none (no branch, for trunk?) didn't work
  either (don't remember the details off-hand).

* Next, I discovered and tried the gcc_trunk branch there.  While it
  matches the patch set you sent here, it lacks most of the compiler
  proper, which only lives on master!?  In addition, the patches in
  there lack support for building libgm2.  Those are present on the
  master branch (which has both trunk and trunc in
  gcc-versionno/gcc/gm2/patches/gcc).  I tried to merge the trees and
  apply the patches manually, but failed again later.

At this point, I gave up.  Am I missing something fundamental here?

Thanks.

Hi Rainer,

it rather depends upon what you want, if you want the latest complete
gm2 grafting onto the svn gcc trunk then these two scripts will create a
patched tree and also rebuild gm2.


[-- Attachment #2: build scripts for gcc trunk --]
[-- Type: application/gzip, Size: 1110 bytes --]

[-- Attachment #3: Type: text/plain, Size: 748 bytes --]


[however please be careful with the scripts - they do assume that
everything will be built in $HOME/GM2 - read and adapt as necessary].

These will build a complete gm2 (from the master) - whereas the gcc_trunk
branch is used to track the patches which are posted to gcc-patches
(which are currently minimal and just build the gm2 driver).

There are snapshots available for 9.1.0, 8.2.0, 6.4.0 as well as back to
the older 4.7.4 series.

http://floppsie.comp.glam.ac.uk/download/c/gcc-9.1.0+gm2-git-latest.tar.gz
http://floppsie.comp.glam.ac.uk/download/c/gcc-8.2.0+gm2-git-latest.tar.gz
http://floppsie.comp.glam.ac.uk/download/c/gcc-6.4.0+gm2-git-latest.tar.gz

these tarballs are created using combine-trees, hope this helps,

Gaius

that's my goal: I'd like to see if gm2 and libgm2 build on Solaris and
pass at least a reasonable number of tests.

> [however please be careful with the scripts - they do assume that

Ok, I will give it a try.

That explains the difference.  While the driver are certainly important
for review, they don't help much by themselves when building the code...

> these tarballs are created using combine-trees, hope this helps,

Certainly.  Thanks a lot.

for clarification - eventually the gcc_trunk branch will contain the
complete compiler as more patches and more tarballs are included.  So
during the integration of gm2 into gcc it should equal the gcc svn trunk
and the current gm2 patch on the gcc-patches mailing list.

I had a look at the GCC 9 version of the patches, with a build including a make
install. Some comments:

 - A parallel build (at least with -j4) isn't working. A sequental
   build works fine.  I think forcing a sequential build will not
   work well, increasing the build time too much.

 - libgm2 multilib builds are not working.  <builddir>/<target>/32/libgm2
   is configured, but not built.

 - The internal tools in the gcclibdir are installed twice, with
   both vanilla names and prefixed/suffixed names.

 - libgm2/configure.a has a libtool version 14:0:0, however all
   shared libraries are installed with soversion 0.

 - no manual page for gm2m.

 - libpth.{a,so} is installed in the system libdir, which
   conflicts with the installation of the libpth packages
   on most distros.

 - There are three letter libraries with pretty generic
   names installed into the system libdir: log, iso, cor,
   min, ulm. At least for log, you have a file conflict
   with another library.  Shouldn't these libraries named
   mpre specific, like libgm2log?

here are some initial issues.  I'll reply to Matthias' mail to expand on
other problems he's raised.

* First, the build broke like this:

/vol/gcc/src/hg/trunk/solaris/gcc/gm2/mc-boot/GRTint.c:57:30: error: 'time' redeclared as different kind of symbol
   57 | typedef enum {input, output, time} VectorType;
      |                              ^~~~
In file included from /usr/include/time.h:12,
                 from /usr/include/sys/time.h:448,
                 from /usr/include/sys/select.h:27,
                 from /usr/include/sys/types.h:665,
                 from /usr/include/stdlib.h:22,
                 from /vol/gcc/src/hg/trunk/solaris/gcc/gm2/mc-boot/Glibc.h:15,
                 from /vol/gcc/src/hg/trunk/solaris/gcc/gm2/mc-boot/GRTint.c:42:
/usr/include/iso/time_iso.h:96:15: note: previous declaration of 'time' was here
   96 | extern time_t time(time_t *);
      |               ^~~~

  I've worked around this by renaming the enum value to vtime.  This
  problem is likely to occur on other targets as well.

* Building gm2.info failed with the makeinfo I happened to have
  installed:

makeinfo --split-size=5000000 --split-size=5000000 -I/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc/gm2 -o /var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc/gm2/gm2.info /vol/gcc/src/hg/trunk/solaris/gcc/gm2/gm2.texi
/vol/gcc/src/hg/trunk/solaris/gcc/gm2/gm2.texi:3070: `Prerequisites' has no Up field (perhaps incorrect sectioning?).
makeinfo: Removing output file `/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc/gm2/gm2.info' due to errors; use --force to preserve.
make[2]: *** [/vol/gcc/src/hg/trunk/solaris/gcc/gm2/Make-lang.in:234: /var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc/gm2/gm2.info] Error 1

  This is from texinfo 4.13, newer than the required minimum of 4.7.
  Even with makeinfo 6.1, there are a couple of warnings:

/vol/gcc/src/hg/trunk/solaris/gcc/gm2/gm2.texi:82: warning: multiple @menu
/vol/gcc/src/hg/trunk/solaris/gcc/gm2/gm2.texi:581: warning: multiple @menu

/vol/gcc/src/hg/trunk/solaris/gcc/gm2/gm2.texi:3070: warning: unreferenced node `Prerequisites'

Other than that, a sequential (only!) multilibbed build succeeded, and I
even managed to get some testsuite results which aren't too bad, again
for both multilibs:

                === gm2 Summary for unix ===

# of expected passes            7800
# of unexpected failures        1729
# of unresolved testcases       1705

                === gm2 Summary for unix/-m64 ===

# of expected passes            7800
# of unexpected failures        1729
# of unresolved testcases       1705

                === gm2 Summary ===

# of expected passes            15600

Hi Rainer,

thanks for the bug report.  Now fixed in the git repro -
the mc bootstrap tool now avoids 'time'.  Also fixed Make-lang.in
to allow parallel builds.

Hi Matthias,

the libraries ./usr/lib/x86_64-linux-gnu/lib{ulm,pim,gm2,cor,iso,min}.a
are not needed the correct locations of the static libraries are:

./usr/lib/gcc/x86_64-linux-gnu/9/m2/ulm/libulm.a
./usr/lib/gcc/x86_64-linux-gnu/9/m2/min/libmin.a

absolutely: I'd go as far as claiming that this is the number one
priority.  Otherwise build and test times are just too long for all but
the most dedicated testers, and forcing a sequential build would be a
showstopper for trunk integration.

The same holds for the current requirement of a non-bootstrap build.  At
least that's what I saw initially: it may be that it works sequentially,
but haven't tried since the build time was way too long already.

True, but the fix is a simple one-liner:

This allowed me to build both 32 and 64-bit gm2 libs on
i386-pc-solaris2.11 and get the testresults I reported earlier, which
are identical for -m32 and -m64.

Here are a couple of other issues I saw:

* There are many many warnings during the build in the gcc/gm2 code.

* The mc output is far too verbose right now: this isn't of interest to
  anyone but gm2 developers ;-)

* Running make check-gm2 in gcc produces gm2 testsuite output directly
  in gcc/testsuite.  This needs to go into a testsuite/gm2 subdir (or
  gm2<N> once the testsuite is parallelized: it is far too large to only
  run sequentially).

* Many tests FAIL like this:

ESC[01mESC[Kxgm2:ESC[mESC[K ESC[01;31mESC[Kfatal error: ESC[mESC[Kcannot execute �<80><98>ESC[01mESC[Kgm2lESC[mESC[K�<80><99>: execvp: No such file or directory
compilation terminated.
compiler exited with status 1
FAIL: gm2/calling-c/datatypes/unbounded/run/pass/m.mod compilation,  -g 

  For one, I didn't have gm2l anywhere in my tree.  Besides, the tests
  absolutely need to be run with -fno-diagnostics-show-caret
  -fno-diagnostics-show-line-numbers -fdiagnostics-color=never

  This problem seems to account for the vast majority of failing tests
  right now:

   6820 xgm2: fatal error: cannot execute ‘gm2l’: execvp: No such file or directory
      6 xgm2: fatal error: no input files

  gm2l and a couple of other tools are built by gm2/Make-lang.in's
  gm2.all.build rule, that the seems not to be referenced anywhere.
  Even after manually building them, the stay in stage1/gm2 and need a
  make gm2l to be copied into gcc/gm2.  This all needs to work without
  such manual steps or without installing gm2 first.

* There are a couple of broken testcase names in gm2.sum, e.g.

PASS: /vol/gcc/src/hg/trunk/solaris/gcc/testsuite/gm2/pim/options/optimize/run/pass/addition.mod compilation, -g {compiler=/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc/xgm2 -B/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/gcc -I/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/i386-pc-solaris2.11/./libgm2/libpim:/vol/gcc/src/hg/trunk/solaris/gcc/testsuite/../gm2/gm2-libs -I/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/i386-pc-solaris2.11/./libgm2/libiso:/vol/gcc/src/hg/trunk/solaris/gcc/testsuite/../gm2/gm2-libs-iso -I/vol/gcc/src/hg/trunk/solaris/gcc/testsuite/gm2/pim/options/optimize/run/pass -fpim -L/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/i386-pc-solaris2.11/./libgm2/libpim/.libs -L/var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/i386-pc-solaris2.11/./libgm2/libiso/.libs}

  Names are required to be unique, and must not contain absolute
  pathnames to allow for comparing different test results.  All this
  stuff in braces above should go.

With the missing gm2l worked around as above, my i386-pc-solaris2.11
testresults are way better now:

                === gm2 Summary for unix ===

# of expected passes            11186
# of unexpected failures        24
# of unresolved testcases       12

                === gm2 Summary for unix/-m64 ===

# of expected passes            10976
# of unexpected failures        156
# of unresolved testcases       90

                === gm2 Summary ===

# of expected passes            22162
# of unexpected failures        180
# of unresolved testcases       102

However, you may want to reconsider if really the whole gm2 testsuite
needs to be torture-tested, i.e. run at -g/-O/-O -g/-Os/-O3
-fomit-frame-pointer/-O3 -fomit-frame-pointer -finline-functions.  This
seems pretty excessive to me.

ok, then I assume that could be the place for the .so files as well (not the
.so.* files/links), if I don't want to install those in the system libdir.

Hi,

Many thanks for all the feedback/bugs/patches.
I've been working through some of these.  The parallel build is now done.

these results are great for solaris.  On the amd64/GNU/Linux I get 12

but then you'll end up with separate m2 subdirs for each multilib build?  That's
maybe not what you want.

And an unrelated one: You are introducing python2 as a build-dependency.
Afaics, it's only one invocation

python ../../src/gcc/gm2/tools-src/def2texi.py -uLibraries -s../../src/gcc/gm2
-b/home/packages/gcc/9/u/gcc-9-9.1.1/build/gcc/gm2 >
/home/packages/gcc/9/u/gcc-9-9.1.1/build/gcc/gm2/gm2-libs.texi

but there might be more implicit python calls via a shebang line.

Also it's python2, not ready to run with python3.  I think you should not rely
on python2 only code anymore.

Hi Matthias,

ah yes, true - I'll convert the scripts to Python 3

It seems to work, however I see

make[11]: Entering directory
'/home/packages/gcc/9/u/gcc-9-9.1.1/build/x86_64-linux-gnu/32/libgm2/libpth/pth'
make[11]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.

not sure what's going wrong.

In both gcc/gm2 and libgm2, there are explicit calls to make, which probably
should bre replaced by $(MAKE).

Hi Matthias,

as far as I know Redhat doesn't support libpth-dev - therefore it was
decided to include libpth in the gm2 tree and autodetect build/install
it as necessary.

That's ok, but then please don't install it as a system library.  that's what
convenience libraries are for (a libpth.a built with -fPIC, which you can link
against).

With a fresh build, configured with

         --program-suffix=-9
         --program-prefix=x86_64-linux-gnu-

the latter set of internal binaries is installed, while I would expect just the
un-pre/post-fixed tool names.

Indeed: I'm pretty pleased by those results myself.

The remaining failures mostly fall in two categories:

Undefined			first referenced
 symbol  			    in file
KeyBoardLEDs_SwitchScroll           /var/gcc/gcc-10.0.0-20190708/11.5-gcc-gas-gm2-no-bootstrap-j1/i386-pc-solaris2.11/./libgm2/libcor/.libs/libcor.so
ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: gm2/coroutines/pim/run/pass/testiotransfer.mod compilation,  -g 
UNRESOLVED: gm2/coroutines/pim/run/pass/testiotransfer.mod execution,  -g  (link failed)

The definition lives in libgm2/libcor/KeyBoardLEDs.c and is Linux-only,
requiring the KGETLED/KSETLED ioctls.  An empty fallback implementation
is missing from the !linux section.

Then there's

/var/tmp//ccrqpjSdcpp:1:failed to find module name
compiler exited with status 1
FAIL: gm2/cpp/pass/cpph.mod,  -g  

FAIL: gm2/pim/fail/TestLong4.mod,  -g  

with no further indication in gm2.log what might be wrong.  Will have a
look.

Most 64-bit testcases FAIL for the same reason:

Undefined			first referenced
 symbol  			    in file
funcString                          /var/tmp//ccGNv4Zd.a(m.o)

FAIL: gm2/calling-c/datatypes/unbounded/run/pass/m.mod compilation,  -g 
UNRESOLVED: gm2/calling-c/datatypes/unbounded/run/pass/m.mod execution,  -g  (link failed)

funcString *is* defined in c.c, but that file is compiled in the .exp
file `under the hood' with exec ${XGCC} (not even visible in gm2.log)
and without the correct multilib flag.

[01m[K/vol/gcc/src/hg/trunk/solaris/gcc/testsuite/gm2/cpp/pass/subaddr.mod:32:3:[m[K [01;31m[Kerror: [m[Kcan only CAST objects of the same size

      |   [01;31m[K^[m[K

FAIL: gm2/cpp/pass/subaddr.mod,  -g  

Haven't looked yet, but might be a generic multilib testing problem.

I also noticed that quite a number of temp files are left behind in
gcc/testsuite:

* many *_m2.s files.

* several .o files:

-rw-r--r-- 1 ro gcc 8928 Jul  9 13:45 cpp.o

* a few *.x[0-5] files:

* 3 others:

-rw-r--r--   1 ro       gcc         4199 Jul  9 14:00 integer_m2.cpp

-rw-r--r--   1 ro       gcc           26 Jul  9 13:56 test.txt

Besides, gm2.log is very full with debug output, making it hard to see
what's going on:

Stuff like

 }

They are currently written with send_log, but should use verbose instead
so they are off by default, but can be enabled if need be by running
runtest with an appropriate number of -v options.

And finally the testsuite should live in gm2.dg.

I still think installing libpth is wrong, however currently all multilib
variants install into $libdir, and not into the system multilib dir, e.g. lib64,
lib32, ...  So the last multilib wins, and you end up with the wrong arch in
your $libdir.

Hi Matthias,

ah thanks for the explanation.  The multilib build system is still new
to me.  So regarding the libpth issue, what happens if the native os
does not provide libpth?  From your experience with building multilib
and shared library packages on multiple platforms - what is the best
solution :-)

I don't know about a best solution, but I contributed changes to
DRUNTIME_LIBRARIES_ZLIB in libphobos/m4/druntime/libraries.m4 and
gcc/doc/install.texi (--with-target-system-zlib).

Or you look at libffi/libgo, with libgo always linking the convenience libffi
library.

Hi Matthias,

thank you - I think we were both working on the same code at the same
time!  I've checked in some fixes to both the master gm2/Make-lang.in
(and 9.1.0 branch).  I've culled gm2m from /usr/bin and relegated it to
libexecsubdir,

Hi Matthias,

many thanks for the build results.  There is a newer version of
gm2/Make-lang.in on the 9.1.0 branch which (quietens the output for mc)
and fixes the gm2l execvp (on other platforms).

The ICE is very interesting!

We don't yet support Modula2 in the traceback tables.  I'll add it.
What is the exact spelling in lang_hooks.name?  "GNU Modula 2"?  Or
"GNU Modula2"?  Or what else :-)

Should I add this to the GCC 9 branch as well?  Does that help testing,
I mean?

Hi Segher,

very close !

A look at the licenses:

libgm2/libiso/*: LGPL 2.1+
libgm2/libmin/libc.c: GPL 3+
libgm2/liblog/*: LGPL 2.1+

gcc/gm2/gm2-libs/Break.def LGPL 2.1+
gcc/gm2/gm2-libs/*.mod LGPL 2.1+
gcc/gm2/gm2-libs/Builtins.mod GPL 3+

I didn't look at everything in gcc/gm2, however it's not clear for me when a
file is LGPL or GPL.  And at least in gm2-libs, it seems to be mixed randomly.
First I thought all definition modules were GPL, and implementation modules were
LGPL, but that's not the case.

So currently all code linked with the runtime libs becomes GPL 3+?

For the ulm lib, the files mention the Ulm university as the copyright holder,
but it's not clear which license these files had before they were imported.

libgm2 seems to be mostly LGPL except for two files. Intended?

fyi, the hook patches for brig, D, Fortran and Go are not yet part of your gm2
repository for the trunk (while they are for gcc-9).  The patches are also
duplicated as trunc and trunk.

I checked that gm2 cross compilers can be built. One minor nit: The man page is
installed without suffix and prefix.

gcc/gm2/Make-lang.in has

GM2_CROSS_NAME = `echo gm2|sed '$(program_transform_cross_name)'`

The program_transform_cross_name macro was removed in 2003, and doesn't do
anything.  The installation of the man page shouldn't be special-cased for a
cross build.

Hi Matthias,

many thanks for the analysis.  I've now:

  *  removed all gnu pth code and rewritten the coroutine libraries to
     use libgcc/gthr.h.
  *  removed all Univ Ulm libraries
  *  changed all remaining library code to use GPL3+ gcc runtime
     extensions
  *  checked all compiler code is GPL3

(on the master branch of gm2)

[I've still working on the testsuite]


regards,
Gaius
