Jon,

Running "powerpc-eabi-gcc --target-help" shows built-in support for a lot
of cpu variants:


PowerPC options:
-a32                    generate ELF32/XCOFF32
-a64                    generate ELF64/XCOFF64
-u                      ignored
-mpwrx, -mpwr2          generate code for POWER/2 (RIOS2)
-mpwr                   generate code for POWER (RIOS1)
-m601                   generate code for PowerPC 601
-mppc, -mppc32, -m603, -m604
                        generate code for PowerPC 603/604
-m403, -m405            generate code for PowerPC 403/405
-m440                   generate code for PowerPC 440
-m7400, -m7410, -m7450, -m7455
                        generate code For PowerPC 7400/7410/7450/7455
-mppc64, -m620          generate code for PowerPC 620/625/630
-mppc64bridge           generate code for PowerPC 64, including bridge insns
-mbooke64               generate code for 64-bit PowerPC BookE
-mbooke, mbooke32       generate code for 32-bit PowerPC BookE
-mpower4                generate code for Power4 architecture
-mcom                   generate code Power/PowerPC common instructions
-many                   generate code for any architecture (PWR/PWRX/PPC)
-maltivec               generate code for AltiVec
-me500, -me500x2        generate code for Motorola e500 core complex
-mspe                   generate code for Motorola SPE instructions



I don't really know about VxWorks.  I think that's a totally separate
problem.  You probably have to build with VxWorks headers and libraries
instead of using newlib.  I seem to recall seeing web pages covering
the use of older gcc versions with VxWOrks, but nothing for 3.x series.
