* Implement DTrace for PowerPC. This includes both 32-bit and 64-bit.jhibbits2012-11-071-1/+2
| | | | | | | | | | | There is one known issue: Some probes will display an error message along the lines of: "Invalid address (0)" I tested this with both a simple dtrace probe and dtruss on a few different binaries on 32-bit. I only compiled 64-bit, did not run it, but I don't expect problems without the modules loaded. Volunteers are welcome. MFC after: 1 month
