[Qemu-ppc] VSX Instruction Set Implementation

[Jacques Mony]

Hello,

 

After going through the archives, I read an interesting thread regarding unimplemented instruction set from PowerISA 2.06. The specific instruction that seems to be called by AIX is stxvd2x, from VSX Instruction Set (new in 2.06 as I can understand).

 

How do one start to implement a instruction sub-set? Where to start? I see there are helpers, TCG, etc… is there a tutorial that explains where to start? I already know it will have to support new encoding forms (XX1-form , XX2-form…) which is not being used yet (afaik), but for the rest, I’m a bit lost.

 

Thanks!
