- snvzz 4y agoUpstream toolchains won't readily accept extensions that aren't part of the standard, and maintaining forks is costly. There is no incentive not to get extensions standardized. In the first place, what's even missing in RISC-V? As of December's 15 extensions, it is pretty much there already, in terms of functionality.
- brucehoult 4y agoExactly. Extend it with what? Intel and AMD each have instructions in their x86 chips that the other doesn't have. No one cares, pretty much. If you're building your own performance-critical software to run on a specific chip then you might enable some of them (or just do "gcc -march=native") but software distributed in binary form generally gets on fine without them.
