[Bug c++/28904] New: operand out of range on Linux/PowerPC

[Bug c++/28904] New: operand out of range on Linux/PowerPC

[glibersat at linux62 dot org]

When trying to build CrystalSpace3d, which is a very big application, on
GNU/Linux, I get errors like this :

{standard input}:1236795: Error: operand out of range (0x0000000000008220 is
not between 0xffffffffffff8000 and 0x0000000000007fff)
(repeated about 300 times)

The file, cs_pyth.cpp generates a huge .S (45Mb).

Every error refers to a "lwz" instruction :
        lwz 4,.LC42716-.LCTOC1(30)
        lwz 4,.LC42718-.LCTOC1(30)
        lwz 4,.LC42720-.LCTOC1(30)
        lwz 4,.LC42722-.LCTOC1(30)
        lwz 4,.LC42724-.LCTOC1(30)
        lwz 4,.LC42726-.LCTOC1(30)

=========

Here's what I'm using :
[sakura>glibersat::crystal]$ g++ -v
Using built-in specs.
Target: powerpc-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-mpfr --disable-softfloat
--enable-targets=powerpc-linux,powerpc64-linux --with-cpu=default32
--enable-checking=release powerpc-linux-gnu
Thread model: posix
gcc version 4.1.2 20060814 (prerelease) (Debian 4.1.1-11)

=========

The complete command line is :
g++ -c -o ./out/linuxppc/debug/plugins/cscript/cspython/cs_pyth.o -I.
-I./include -I./include -pipe -Wall -Wno-unknown-pragmas -I/usr/local/include
-fno-exceptions -g3 -DCS_DEBUG -fPIC -I/usr/include/python2.3 -DSWIG_GLOBAL
-Wno-unused -Wno-uninitialized -fno-strict-aliasing 
./out/linuxppc/debug/plugins/cscript/cspython/cs_pyth.cpp

=========

I can't attach the .i file since it's really big. You can get it there :
http://glibersat.linux62.org/~glibersat/cs_pyth.ii

Thanks !

Hmm, I am going to go out on a limb and say we should 
produce about the following (hopefully I get the right macros):
la temp, ha16(.LC42716-.LCTOC1)(30)
lwz rn, lo16(.LC42716-.LCTOC1)(temp)

This is like what Darwin does for PIC.

------- Comment #2 from pinskia at gcc dot gnu dot org  2006-08-31 04:34 -------
well, the syntax would be more like:
        addis 9,(.LC42716-.LCTOC1)@ha(30)
        lwz 0,.LC42716-.LCTOC1)@l(9)

But I don't know if this syntax will work.

------- Comment #3 from amodra at bigpond dot net dot au  2006-09-05 22:50 -------
This is a limitation of the -fPIC implementation used on powerpc-linux.  You
get a maximum of 64K bytes of GOT entries per function (ie. 16K entries). 
-fpic is even more limited, with only 64K bytes of GOT for the entire
executable.  (-fpic used to be 32k for the entire executable until the linker
was enhanced.)

the same here on gentoo-ppc-2.6.21, using gcc-4.1.2
Powerbook G4(5,6)
trying to compile Crystalspace v1.2 --with-python
When ommiting -fPIC OR using --without-python, the build works.
I will see if a revert to 4.1.1 brings any advancement for 4.1.2 is marked as
testing on gentoo-ppc.

They have been improvements in 4.2.0 with respect of having a smaller GOT.  Can
you try 4.2.0?

uh, i'd like to...give me a few days to figure out how i can do a proper
upgrade or setup a sandbox for testing.
I will check back with the results.

I have checked with 4.2.0 and it produces the same error.
Maybe i'd like to rebuild python too with 4.2?

crystalspace also has a bug report for this
(http://www.crystalspace3d.org/trac/CS/ticket/210)

as mentioned there, one could try this
http://www.crystalspace3d.org/trac/CS/ticket/258 which is using a special
branch for the python modules. using this branch, i had no problem building the
python modules. maybe it's worth a look for you :)
i dont really get the point...but, eager to...

The original reporter seems to have resolved this to their satisfaction in
their CrystalSpace3d bug report.  This report was due to running up against a
limitation of the -fPIC implementation.
