PS3 and Xbox360 IDA Plugin Update (again)

As more special PPC instructions are stumbled across, support for them gets added to the plugin. I know I could go through an exhaustive list of all instructions and add them all, but for now I am content with adding them a few at a time ūüėõ

PPC Altivec plugin v1.6 for IDA v5.6

Support added for the instructions: attn, lwsync, ptesync, tlbiel, tlbie, tlbi, slbie.

Also added support for the SystemSim “callthru” instruction (should this even be used outside of a simulator?) and lastly an instruction that I cannot find any information about. The hex value is 0x02002000 so for now I have added this instruction as opcode_02002000 so that it will at least disassemble to code and can therefore be treated as code. If anyone knows what this instruction is please let me know :)

PS3 and Xbox360 IDA Plugin Update

Here is version 1.5 of the PPC Altivec Plugin for IDA v5.6 which adds support for special instructions that are used by some PPC based devices. This was originally written by Dean Ashton and then updated by Takires.

This is useful when disassembling Xbox360 and PS3 binaries in IDA as they utilise these special instructions that are not supported by IDAs built in PPC disassembler module.

I have done some fixes to instructions that were previously handled incorrectly, as well as adding support for some new instructions. I also fixed an issue where instruction sizes were being reported incorrectly resulting in an incorrect disassembly.
