RS6000 to G4 assembly changes

[Robert Neugebauer]

I am not trying to build a cross compiler, I am not trying to build GCC.
My course at university uses its own compiler called uC++ (Micro C++).

The compiler thus far only has the following targets that work:
        dmake sun-sparc-sunos
        dmake sun-sparc-svr4
        dmake sun-m68k-sunos
        dmake dec-ultrix-mips
        dmake dec-alpha
        dmake sgi-mips-r4000
        dmake sgi-mips-r3000
        dmake ibm-rs6000
        dmake hp-hppa
        dmake pc-i386-linux
        dmake gizmo

By my knowledge rs6000 is a RISC based architecture, thus I tried to build
uC++ using the target ibm-rs6000. This resulted in an unrecognized opcode
movl during compilation.

If someone knows what the similar instruction on my G4 is, and any other
problems I might/will encounter, I would appreciate it.

Thank You
