Yep all these ISA have a 16bit extension.
- cesarb 9y agoExcept, for some reason, ARM's new 64-bit ISA, which has 32-bit instructions only. I wonder how long before they release a "Thumb-64" extension...
- pcwalton 9y agoI doubt it'll be as easy as it was for 32-bit ARM because AArch64 has no (well, only a few) predicated instructions. Instead, the 64-bit ISA effectively uses those bits to name additional registers. AArch64 already has similar code density to x86-64 anyway.
