building gcc 4.0.0 on Solaris

[Dimitri Papadopoulos-Orfanos]

Hi,
I'm attempting to build gcc 4.0.0 on Solaris. I have been unable to 
build gcc or at least some of its components since the release of gcc 3.4.

Here are a few details on my system:
 - Solaris 8 7/01
 - Sun's as/ld
   as: Sun WorkShop 6 99/08/18
   ld: Software Generation Utilities - Solaris Link Editors: 5.8-1.286
 - GNU binutils 2.15
I've tried two approaches.
1) Using Sun's as/ld. I build gcc this way:
        cd /tmp
        gtar xjf ~/gcc-4.0.0.tar.bz2
        mkdir gcc
        cd gcc
        setenv CONFIG_SHELL /bin/ksh
        /tmp/gcc-4.0.0/configure \
                --prefix=/usr/local/gcc-4.0.0
        gmake bootstrap
The build fails with the following message:
ld: fatal: relocation error: R_SPARC_DISP32:
file .libs/libstdc++.lax/libsupc++convenience.a/vterminate.o:
symbol <unknown>: offset 0xfccd33ad is non-aligned
I've searched Google for this error and came across similar error 
messages without finding a solution:
http://gcc.gnu.org/ml/gcc-prs/2003-03/msg00497.html

Any clues?

2) Using GNU binutils. I build gcc this way:
        cd /tmp
        gtar xjf ~/gcc-4.0.0.tar.bz2
        mkdir gcc
        cd gcc
        setenv CONFIG_SHELL /bin/ksh
        /tmp/gcc-4.0.0/configure \
                --prefix=/usr/local/gcc-4.0.0 \
                --with-as=/usr/local/binutils/bin/as \
                --with-ld=/usr/local/binutils/bin/ld
        gmake bootstrap
The build fails while compiling the Java libraries with gcj. No error 
message appears because the oputput of gcj is discarded by the build 
system. Running the last command line manually, I get the following 
error message:
/tmp/GCC/gcc/gcj [...] -o java/lang/StrictMath.o
/tmp/ccMGENqa.s: Assembler messages:
/tmp/ccMGENqa.s:10374: Error: Illegal operands:
There are only 32 single precision f registers; [0-31]

I've found out this is a known issue with the current GNU binutils 
package. See for example:
http://lists.freebsd.org/pipermail/freebsd-sparc64/2005-March/002879.html
As far as I can understand, it's not possible to build gcc 4.0.0 and gcc 
3.4.* using GNU binutils with current release 2.15 of GNU binutils. One 
has to use the CVS sources or at least one file.

Would it be possible to document this requirement in the platform pages?
http://gcc.gnu.org/install/specific.html#sparc-sun-solaris2

Speaking of the sparc-sun-solaris2* platform, I read:
        GCC 3.4 changed the default debugging format from STABS
        to DWARF-2 for 32-bit code on Solaris 7 and later. If you
        are using the Sun assembler, this change apparently runs
        afoul of Sun bug 4910101, for which (as of 2004-05-23)
        there is no fix. A symptom of the problem is that you
        cannot compile C++ programs like groff 1.19.1 without
        getting messages similar to the following:
        ld: warning: relocation error: R_SPARC_UA32: ...
          external symbolic relocation against non-allocatable
          section
          .debug_info cannot be processed at runtime:
          relocation ignored.
        To work around this problem, compile with -gstabs+
        instead of plain -g
I had a look at Sun Online Support and found:
        Bug ID: 4910101
        Synopsis: fbe needs a way to reference section labels
        Category: compiler
        Subcategory: assembler-x86
        Description:
        The bug was first found with the -misalign flag, but the
        real bug is because the code is being passed through the
        assembler.
        Integrated in releases: k2_dev
        Summary: fbe needs a way to reference section labels
Therefore :
1) This seems to be x86-specific, so I would suggest moving this 
paragraph from sparc-sun-solaris2* to i?86-*-solaris2*
2) It looks like there is a fix, however I don't know what k2_dev is, 
maybe this is an internal development version and the fix has not been 
relesed yet.
