Cross Compiler and Name Mangling Differences

[Jonathan Pryor <jpryor at image dot kodak dot com>]

I built a cross compiler to generate sparc-sun-solaris2.5.1 code
from i686-pc-linux-gnu (Red Hat 7.0).

The Solaris "native" compiler is GCC-2.95.2 with binutils-2.9.5.0.31,
so the cross compiler is using the same versions of binutils and gcc.

I have the cross-compiler built, but I'm facing a problem when
moving object files between platforms.  It appears that the name
mangling is different between the solaris native gcc compiler and
the linux->Solaris cross compiler.

For example, the output of ``nm'' of the linux object file is:

   00000000 a *ABS*
            U _Q_qtod
   00000000 ? __FRAME_BEGIN__
            U __ls__7ostreamPCc
            U __ls__7ostreamPFR7ostream_R7ostream
            U __throw
            U cout
            U endl__FR7ostream
   00000000 t gcc2_compiled.
   00000000 T main

The output of ``nm'' for the solaris-gcc compiler object file is:

   00000000 a *ABS*
            U _Q_qtod
   00000000 ? __FRAME_BEGIN__
            U __ls__7ostreamPCc
            U __ls__7ostreamPFRB0_RB0
            U __throw
            U cout
            U endl__FR7ostream
   00000000 t gcc2_compiled.
   00000000 T main

The only difference is the 5th line.  The Linux cross-compiler
mangling and the Solaris native mangling are different for the
function type ``ostream::operator<<(ostream &(*)(ostream &)).''

Is there any reason for this to be happening, and is there any
way to fix it?

Thanks.
