PowerPC GNU Compiler question

	Are you asking about the C++ ABI and mangling conventions?  That
*is* compiler-dependent, but the system calling convention ABI is not
compiler-dependent.

	GCC 3 now uses the IA-64 C++ ABI across all architectures.  That
specifies how vtables are layed out and how C++ symbols are mangled, but
the details of how the parameters are passed to methods still follow the
system-specific ABI.

	The C++ ABI for Itanium (used by GCC for all architectures) is
detailed at:
