Beyond recompiling, wouldn't porting 'i' to another architecture, say x86-64 or ARM64, would require the addition some sort of PowerPC AS tags active mode - instructions to set the "this is a valid pointer bits" ?
- skissane 3y agoARM already has tagged memory support - https://source.android.com/docs/security/test/memory-safety/arm-mte https://source.android.com/docs/security/test/memory-safety/... - although I don’t know if it is sufficiently equivalent to the PowerPC AS feature. And then ARM also has CHERI / Morello, which is still at the research prototype stage, but may be production ready in a few more years
