A somewhat heartbreaking message seen on my Solaris 10 SPARC server
wherein I use the very strict Oracle Studio 12.4 compiler tools with
strict C99 compliance CFLAGS :

This could just be because I start the process using C99 compliance
mode and a collection of restrictive and strict CFLAGS with a debug
compile such that I can single step along later.

My CFLAGS looks like this :

***@mimas_$ echo $CFLAGS
-m64 -xtarget=ultra2 -xarch=sparcvis -xchip=ultra2 -xcache=generic
-errwarn=%none -errhdr=%user -erroff=%none -errtags=yes -errfmt=error

-D_POSIX_PTHREAD_SEMANTICS -D_LARGEFILE64_SOURCE -D_XOPEN_SOURCE=600


Note the option -Xc and -D_XOPEN_SOURCE=600 there. Those two alone are
usually enough to catch every possible variation that strays away from
C99 and SUSv3. Enitely too pedantic I know but it is a very good test
to do on just about any open source code.

Note that I have libatomic_ops-7.4.4 extracted and in a sub-directory
called libatomic_ops thus :

That seems to look fine but I get Makefile's that all have slightly
broken CFLAGS in them because an option "-O" has been pre-pended to the
CFLAGS. That options doesn't mean anything to the compiler and so it
halts the whole process. I manually edit the Makefile's to remove the
option -O and then run GNU make. Then I rapidly get that error message.

I figure I could now switch over to cc and some more relaxed CFLAGS and
give this a try again and see what happens but if it is possible to
push the sources past a very strict compiler then the results could be
of value to the project.

ps: I'm not really pedantic .. I just like to test with C99 first.

You might want to put some #error lines temporarily into here (in
gcconfig.h) to see what is failing to detect your machine. And/or just run
the preprocessor and examine the ouput.

That seems to look fine but I get Makefile's that all have slightly
broken CFLAGS in them because an option "-O" has been pre-pended to the
CFLAGS. That options doesn't mean anything to the compiler and so it
halts the whole process. I manually edit the Makefile's to remove the
option -O and then run GNU make. Then I rapidly get that error message.
I figure I could now switch over to cc and some more relaxed CFLAGS and
give this a try again and see what happens but if it is possible to
push the sources past a very strict compiler then the results could be
of value to the project.

ps: I'm not really pedantic .. I just like to test with C99 first.

To amplify some more .. the only thing that "The collector has not been
ported to this machine/OS combination." means is that no one tried it with
your particular combination of machine/compiler. If your machine is similar
to others that work -- or if it works with other compilers -- then the
chances are good that the problem is simply that your compiler isn't
defining the preprocessor macros the header files are looking for.

You can find what preprocessor macros are defined with:

gcc -dM -E - </dev/null

Well, that works for gcc, g++, clang, clang++.

I'm not familiar with your compiler, but it appears that you're using the
-Xc flag and according to this page ...

https://docs.oracle.com/cd/E19205-01/819-5265/6n7c29df6/index.html

.. when -Xc is used none of "sun", "sparc" or "unix" are defined. So you
might try adding tests for "__sun", "__sparc" and "__unix" to the tests.

e.g.

# if (defined(sun) || defined(__sun)) && (defined(sparc) ||
defined(__sparc))
# define SPARC
/* Test for SunOS 5.x */
# include <errno.h>
# define SOLARIS
# define mach_type_known
# endif

This might or might not be enough to make everything work properly, but at
least it means the build system will now try to compile the code.

Post by Bruce Hoult
You might want to put some #error lines temporarily into here (in
gcconfig.h) to see what is failing to detect your machine. And/or just run
the preprocessor and examine the ouput.
# if defined(sun) && (defined(sparc) || defined(__sparc))
# define SPARC
/* Test for SunOS 5.x */
# include <errno.h>
# define SOLARIS
# define mach_type_known
# endif
# if defined(sparc) && defined(unix) && !defined(sun) && !defined(linux) \
&& !defined(__OpenBSD__) && !defined(__NetBSD__) \
&& !defined(__FreeBSD__) && !defined(__DragonFly__)
# define SPARC
# define DRSNX
# define mach_type_known
# endif

This could just be because I start the process using C99 compliance
mode and a collection of restrictive and strict CFLAGS with a debug
compile such that I can single step along later.

Note the option -Xc and -D_XOPEN_SOURCE=600 there. Those two alone are
usually enough to catch every possible variation that strays away from
C99 and SUSv3. Enitely too pedantic I know but it is a very good test
to do on just about any open source code.

That seems to look fine but I get Makefile's that all have slightly
broken CFLAGS in them because an option "-O" has been pre-pended to the
CFLAGS. That options doesn't mean anything to the compiler and so it
halts the whole process. I manually edit the Makefile's to remove the
option -O and then run GNU make. Then I rapidly get that error message.
I figure I could now switch over to cc and some more relaxed CFLAGS and
give this a try again and see what happens but if it is possible to
push the sources past a very strict compiler then the results could be
of value to the project.

To amplify some more .. the only thing that "The collector has not been
ported to this machine/OS combination." means is that no one tried it
with your particular combination of machine/compiler. If your machine is
similar to others that work -- or if it works with other compilers --
then the chances are good that the problem is simply that your compiler
isn't defining the preprocessor macros the header files are looking for.
gcc -dM -E - </dev/null
Well, that works for gcc, g++, clang, clang++.
I'm not familiar with your compiler, but it appears that you're using
the -Xc flag and according to this page ...
https://docs.oracle.com/cd/E19205-01/819-5265/6n7c29df6/index.html
.. when -Xc is used none of "sun", "sparc" or "unix" are defined. So you
might try adding tests for "__sun", "__sparc" and "__unix" to the tests.
e.g.
# if (defined(sun) || defined(__sun)) && (defined(sparc) ||
defined(__sparc))
# define SPARC
/* Test for SunOS 5.x */
# include <errno.h>
# define SOLARIS
# define mach_type_known
# endif
This might or might not be enough to make everything work properly, but
at least it means the build system will now try to compile the code.

Thank you for the reply because I was flailing a bit here trying to
figure out what the issue was. Seems to be libatomic_ops is broken
somewhere.

I found the world is a lot easier to deal with by just letting go
of the reins a small bit :-) so I stopped trying with the c99 compiler
which is obscenely strict and switched over to just cc. That works.

Sort of.

The whole process seems to work fine past configure and into the
compile right up until we need to deal with :

libtool: error: 'libatomic_ops/src/atomic_ops_sysdeps.lo' is not a
valid libtool object

Weird error.

There appears to be a strange assembly language source file in
the libatomic_ops area called libatomic_ops/src/atomic_ops_sysdeps.S
however there isn't much in it :

mimas$ cat libatomic_ops/src/atomic_ops_sysdeps.S
/*
* Include the appropriate system-dependent assembly file, if any.
* This is used only if the platform supports neither inline assembly
* code, nor appropriate compiler intrinsics.
*/

#if !defined(__GNUC__) && (defined(sparc) || defined(__sparc))
# include
"atomic_ops/sylibatomic_ops/src/atomic_ops_sysdeps.sdeps/sunc/sparc.S"
#endif


Well that is strange because assembly can be compiled no problem.

I look and see that something was done for sure :

mimas$ ls -lap .libs/atomic_ops_sysdeps.o
-rw-r--r-- 1 dclarke devl 656 Nov 21 14:47
.libs/atomic_ops_sysdeps.o

mimas$ ls -lap atomic_ops_sysdeps.o
-rw-r--r-- 1 dclarke devl 656 Nov 21 14:47 atomic_ops_sysdeps.o


So evil libtool comes along later and seems to go looking for
libatomic_ops/src/atomic_ops_sysdeps.lo which does not exist at all and
the whole process comes to a halt.

In fact the entire build process related to that file looks like :


Step 1 :

libtool: error: 'libatomic_ops/src/atomic_ops_sysdeps.lo' is not a
valid libtool object


So this is quite strange. The absence of the weird ".lo" file which only
libtool needs.

Something went sadly wrong with libatomic_ops :

mimas$ cd libatomic_ops/src/

mimas$ ls -lo atomic_op*
-rw-r--r-- 1 dclarke 7446 May 24 2016 atomic_ops.c

drwxr-xr-x 10 dclarke 25 May 24 2016 sysdeps


No object files seen there at all and that means
libatomic_ops/src/atomic_ops_sysdeps.lo is missing and so is the object
file. However it does exist as :

mimas$ find . | grep "atomic_ops_sysdeps"
./.libs/atomic_ops_sysdeps.o
./atomic_ops_sysdeps.o
./libatomic_ops-7.4.4/src/.deps/atomic_ops_sysdeps.Plo
./libatomic_ops-7.4.4/src/atomic_ops_sysdeps.S
./atomic_ops_sysdeps.lo

The problem is somewhere down inside the libatomic sources.

I wrote a simple link hack.sh thus and ran it :

mimas$ cat hack.sh
#!/bin/ksh
/opt/solarisstudio12.4/bin/cc -\# -H \

So the problem seems to be in the libatomic_ops region.

To amplify some more .. the only thing that "The collector has not been
ported to this machine/OS combination." means is that no one tried it
with your particular combination of machine/compiler.

I believe that the OP's issue is that the collector HAS been tried with
that particular combination of machine and compiler.

Just not with that particular combination of *options*.

Post by Bruce Hoult
gcc -dM -E - </dev/null
Well, that works for gcc, g++, clang, clang++.

That's a gcc-ism; clang copied a lot gcc-isms.
I cannot find an analogue of that option in the cc manual page.

The likeliest problem is headers testing 'sparc' instead of '__sparc'.
Since sun and sparc are only defined when __sun and __sparc are, there
doesn't seem to be any point in ever testing for 'sun' or 'sparc';
they are "legacy" macros.

[Ivan Maidanski]

The following commit treats __amd64 as __amd64__ and __sun as sun: https://github.com/ivmai/bdwgc/commit/7f82ed2046cbc4bb594e7c2162d40c819daee111

Thank you for the reply and the patch. However I am past that point in
that I stopped using the C99 compiler and switched to the general cc
compiler which generally works for all code. However it is not going
to accept a lot of gnu'isms or clang special tricks. It is just a flat
C compiler and still has a lot of strict code standards expectations.

Having said all that, I was making goog progress however the atomic ops
code fails in a strange way. I detailed all that earlier. However here
it is :

---------------------- from 22nd Nov -------------------
Seems to be libatomic_ops is broken somewhere.

I found the world is a lot easier to deal with by just letting go
of the reins a small bit :-) so I stopped trying with the c99 compiler
which is obscenely strict and switched over to just cc. That works.

The whole process seems to work fine past configure and into the

libtool: error: 'libatomic_ops/src/atomic_ops_sysdeps.lo' is not a

Weird error.

There appears to be a strange assembly language source file in
the libatomic_ops area called libatomic_ops/src/atomic_ops_sysdeps.S

#if !defined(__GNUC__) && (defined(sparc) || defined(__sparc))
# include
"atomic_ops/sylibatomic_ops/src/atomic_ops_sysdeps.sdeps/sunc/sparc.S"
#endif


Well that is strange because assembly can be compiled no problem.

I look and see that something was done for sure :

mimas$ ls -lap .libs/atomic_ops_sysdeps.o

libtool: error: 'libatomic_ops/src/atomic_ops_sysdeps.lo' is not a
valid libtool object


So this is quite strange. The absence of the weird ".lo" file which only
libtool needs.

Something went sadly wrong with libatomic_ops :

mimas$ cd libatomic_ops/src/

mimas$ ls -lo atomic_op*
-rw-r--r-- 1 dclarke 7446 May 24 2016 atomic_ops.c

-rw-r--r-- 1 dclarke 27996 May 24 2016 generalize.h
drwxr-xr-x 10 dclarke 25 May 24 2016 sysdeps


No object files seen there at all and that means
libatomic_ops/src/atomic_ops_sysdeps.lo is missing and so is the object
file. However it does exist as :

mimas$ find . | grep "atomic_ops_sysdeps"
./.libs/atomic_ops_sysdeps.o
./atomic_ops_sysdeps.o
./libatomic_ops-7.4.4/src/.deps/atomic_ops_sysdeps.Plo
./libatomic_ops-7.4.4/src/atomic_ops_sysdeps.S
./atomic_ops_sysdeps.lo

The problem is somewhere down inside the libatomic sources.

I wrote a simple link hack.sh thus and ran it :

mimas$ cat hack.sh
#!/bin/ksh

Which works ( other than undefined symbols that must exist somewhere ) :

So the problem seems to be in the libatomic_ops region.

Does it work if you disable threads (and therefore don't use atomic ops)?

Thank you for the reply and the patch. However I am past that point in
that I stopped using the C99 compiler and switched to the general cc
compiler which generally works for all code. However it is not going
to accept a lot of gnu'isms or clang special tricks. It is just a flat
C compiler and still has a lot of strict code standards expectations.
Having said all that, I was making goog progress however the atomic ops
code fails in a strange way. I detailed all that earlier. However here
---------------------- from 22nd Nov -------------------
Seems to be libatomic_ops is broken somewhere.
I found the world is a lot easier to deal with by just letting go
of the reins a small bit :-) so I stopped trying with the c99 compiler
which is obscenely strict and switched over to just cc. That works.
Sort of.
The whole process seems to work fine past configure and into the
libtool: error: 'libatomic_ops/src/atomic_ops_sysdeps.lo' is not a
valid libtool object
Weird error.
There appears to be a strange assembly language source file in
the libatomic_ops area called libatomic_ops/src/atomic_ops_sysdeps.S
mimas$ cat libatomic_ops/src/atomic_ops_sysdeps.S
/*
* Include the appropriate system-dependent assembly file, if any.
* This is used only if the platform supports neither inline assembly
* code, nor appropriate compiler intrinsics.
*/
#if !defined(__GNUC__) && (defined(sparc) || defined(__sparc))
# include "atomic_ops/sylibatomic_ops/src/atomic_ops_sysdeps.sdeps/sun
c/sparc.S"
#endif
Well that is strange because assembly can be compiled no problem.
mimas$ ls -lap .libs/atomic_ops_sysdeps.o
-rw-r--r-- 1 dclarke devl 656 Nov 21 14:47
.libs/atomic_ops_sysdeps.o
mimas$ ls -lap atomic_ops_sysdeps.o
-rw-r--r-- 1 dclarke devl 656 Nov 21 14:47 atomic_ops_sysdeps.o
So evil libtool comes along later and seems to go looking for
libatomic_ops/src/atomic_ops_sysdeps.lo which does not exist at all and
the whole process comes to a halt.

Does it work if you disable threads (and therefore don't use atomic ops)?

I can give that a try but, would that be wise? I need libgc as a
downstream dependency for gcc because gcc needs autogen which needs
guile which needs libgc which needs atomic_ops.

Welcome to dependency hell. :-)

So I can give it a try and see what happens but I would think the right

Hopefully there is also a testsuite ?

Looks good except for a core dump. See my next email post please Sir.

At this point I will dig into the core dump during the testsuite and see
why bufp went well into nowhereland at line 3597 of os_dep.c.

At the moment I see that the bufp starts off at 3554 nicely :

3554: bufp = GC_proc_buf;


(dbx) print GC_proc_buf

GC_proc_buf = 0x100157000 ""


seems safe enough.

Then we jump around a bit using the sizeof(some struct) from thereon
downwards.

Would love to single step through this.

In any case .. I am looking into it.
