[Bug libgcj/32465] New: Linking 64-bit libgcj.so fails on Solaris 10/x86: non-PIC code despite -fPIC

[gcc-bugzilla at gcc dot gnu dot org]

A mainline bootstrap as of 20070618 on Solaris 10/x86 with the bundled gas
2.15 and my patch to support boehm-gc for x86-64

     http://gcc.gnu.org/ml/java-patches/2007-q2/msg00330.html

fails when linking the 64-bit libgcj:

[ca. 6800 lines omitted]
gnu::gcj::runtime::FinalizerThread::finalizer_ready    0x602           
gnu/gcj/.libs/runtime.o
ld: fatal: relocations remain against allocatable but non-writable sections
collect2: ld returned 1 exit status

I've checked for some of the affected object files that they have been
built with -fPIC, nonetheless text relocations remain, thus breaking the
link.

Environment:
System: SunOS erebus 5.11 snv_60 i86pc i386 i86pc
Architecture: i86pc


host: i386-pc-solaris2.10
build: i386-pc-solaris2.10
target: i386-pc-solaris2.10
configured with: /vol/gcc/src/gcc/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --with-gnu-as
--with-as=/usr/sfw/bin/gas --with-gmp=/vol/gcc --with-mpfr=/vol/gcc
--enable-languages=c,c++,fortran,java,objc,ada --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as described above.

Fix:
It is possible to link with -mimpure-text as a workaround.

On Linux, I got

0000000002e1b960     1 OBJECT  LOCAL  HIDDEN   25
gnu::gcj::runtime::FinalizerThread::finalizer_ready

It looks like assembler/linker on Solaris don't have proper visibility
support.

BTW, the last symbol visibility bug in GNU binutils was fixed on
2006-12-12.

This is

221554: 0000000003024d80     1 OBJECT  GLOBAL DEFAULT  256
gnu::gcj::runtime::FinalizerThread::finalizer_ready

on Solaris 10.

The assembler (gas 2.15 bundled with Solaris) does, but since I'm using the
native linker, gcc/configure.ac disables hidden support.  It should work in
Solaris 10, though.  Due to PR libgcj/32462 (which happens with GNU ld,
too), I haven't tried gas and gld yet.

------- Comment #6 from ro at gcc dot gnu dot org  2007-07-03 18:11 -------
This is a regression from 4.2.1.

I'm uploading the assembler files corresponding to gnu/gcj/.libs/runtime.o and
built with gcj 4.2.1 20070611 and 4.3.0 20070618 for comparison.

------- Comment #7 from ro at gcc dot gnu dot org  2007-07-12 10:20 -------
Like PR libgcj/32462, this is also caused by this patch:

2007-04-03  Andrew Haley  <aph@redhat.com>

        * jvgenmain.c (main): Change main to use class$, not class$$.
        (do_mangle_classname): Likewise.
        * class.c (hide): New function.
        (add_field): Hide everything that shouldn't be visible outside a
        DSO.
        (build_static_class_ref): Likewise.
        (build_classdollar_field): Likewise.
        (make_class_data): Likewise.
        (layout_class_method): Likewise.
        * expr.c (special_method_p): New function.

        * class.c (push_class): Don't bogusly guess the source filename.
        * jcf-parse.c (give_name_to_class): Don't set input_location from
        DECL_ARTIFICIAL decls.

Again, the missing visibility support in this configuration causes the problem.
