Hm, I suppose disabling the static libstdc++ isn't supposed to work anymore.
Ian - should we in this case link libstdc++ dynamically with all the possible
issues that might have?

I think we should change --disable-static applied to libstdc++ so that it
simply does not install the static libstdc++.  Then we can continue to link gcc
statically against libstdc++, which I think is what we need to do.

Build maintainers, any ideas how to do this?  I guess the toplevel configure
should not pass --disable-static to libstdc++ configure then, but some other
option, but no idea how to arrange in automake build, but no install, of the
*.a library.
For 4.7 the alternative could be to
--disable-build-poststage1-with-cxx --disable-build-with-cxx if
--disable-static is seen (or error out if explicitly both options are passed).

You can just set enable_static=no early in libstdc++-v3/configure.ac.  It will
still install libstdc++-v3.a, which is a bit ugly, but that's quite hard to
achieve due to libtool.

One alternative is to build a convenience library (always static) for
libstdc++.  Then you build the shared library from it, and link gcc to the
convenience library.

--- Comment #5 from Benjamin Kosnik <bkoz at gcc dot gnu.org> 2012-01-19 08:52:04 UTC ---

As per #4, here's the convenience library approach.

With this, libstdc++.so is composed of three convenience libraries:
  1. libsupc++convenience.la
  2. libstdc++98convenience.la
  3. libstdc++11convenience.la

This seems like it will work, but haven't reproduced this issue yet so can't
tell for certain.

I'm not exactly sure how to use these convenience libraries instead of
libstdc++.a in the gcc build process. But perhaps somebody else can figure out
that part....

The convenience library can be linked with -L.../.libs -lsupc++convenience
-lstdc++convenience98.

But it really looks like you attached the wrong patch?

I still don't get this part of it: "Then you build the shared library from it,
and link gcc to the convenience library."

When there is not one convenience library, but three. Seems like my options
are:

1) combine the three convenience libraries into one, meta or super convenient
library

2) link gcc with libstdc++98convenience + libstdc++11convenience + libsupc++
instead of libstdc++

Right?

Yes, either should work.  I don't think it's too inconvenient (sorry...) to
link with the three libraries.  Does GCC use stdc++11 features?

Right now I think cc1/cc1plus/etc. would be happy even with an empty
libstdc++.a (they are compiled with -fno-exceptions -fno-rtti, so shouldn't
need even libsupc++) and go1 I think uses just the c++98 stuff and libsupc++.

Changes:

1) nest source SUBDIRS in toplevel src directory, so src/c++98, src/c++11.
2) add supra-convenient library, libstdc++convenience.la to src Makefile.am as
a target

The question is now, how do I get gcc to link with libstdc++convenience.la
instead of libstdc++ when --disable-static?

gcc just uses -static-libstdc++, so presumably the easiest would be if in some
subdirectory we linked this libstdc++convenience.la into a noinst libstdc++.a.

Well I tried to just use the generated Makefile rules to hack together a
solution for --disable-static using the convenience libraries

My plan was to generate a libstdc++convenience library always, and then if
libstdc++.a is not created as per the usual (ie, --disable-static), then to
create it from libstdc++convenience. 

Like so:


libstdc++-v3/src/Makefile.am:

# Make a non-installed convenience library, so that --disable-static
# may work.
libstdc++convenience.la: $(toolexeclib_LTLIBRARIES)
    $(CXXLINK) $(libstdc___la_LIBADD) $(LIBS); \
    if test ! -f .libs/libstdc++.a; then \
      cp .libs/libstdc++convenience.a .libs/libstdc++.a; \
    fi; \
    echo `date` > stamp-libstdc++convenience; 


results in the build completing and:

I'm going to check this with cross compiles, and then if that works check it
in.

The hacky-bits for copying libstdc++ can hopefully be cleaned up at a later
date or by a certified build genius.

Actually, please scratch that.  I was using wrong abilist command line.
With:
readelf -Ws $1 | sed -n '/\.symtab/,$d;/ UND
/d;/@GLIBC_PRIVATE/d;/\(GLOBAL\|WEAK\|UNIQUE\)/p' | awk '{ if ($4 == "OBJECT")
{ printf "%s %s %s %s %s\n", $8, $4, $5, $6, $3 } else { printf "%s %s %s
%s\n", $8, $4, $5, $6 }}' | LC_ALL=C sort -u
it shows just that these symbols are now STB_GNU_UNIQUE while they were
previously STB_GLOBAL.  Not a bug therefore.

Mine.

Still remaining are

1) update libstdc++ maintainer docs
2) --enable-debug fix

We have performance degradation of 447.dealII benchspec 2006.It was happend
bcause thre are no inlining in a library routine from libstdc++-v3/src/tree.cc

const _Rb_tree_node_base*  _Rb_tree_increment(const _Rb_tree_node_base* __x)
throw ()
{    
return Rb_tree_increment(const_cast&lt;_Rb_tree_node_base*&gt;(_x));  }

We have performance degradation of 447.dealII benchspec 2006.It was happened
because there are no inlining a library routine '_Rb_tree_node_base' from
libstdc++-v3/src/tree.cc

const _Rb_tree_node_base*  _Rb_tree_increment(const _Rb_tree_node_base* __x)
throw ()
{    
  return Rb_tree_increment(const_cast&lt;_Rb_tree_node_base*&gt;(_x));
}

I found out that the degradation is caused by absence of -fPIC flag in
compilation command line. If I add the flag to command line the inlining is
happened.
