Fair, but I still think they should switch. I don't think it would be too difficult anyway. It should mostly amount to rewrite of the decoder as can be inferred from the fact that it is mostly a superset of MIPS64.
The perceived benefits, are being independent of the west on technology. Which RISC-V already provides.
There are chinese companies making RISC-V chips and machines: https://milkv.io/pioneer
I get the impression that LoongArch has more priority because they fully own that ISA which means foreign entities such as the US Empire can have 0 impact on it. If something happens to RISC-V that could put China at a disadvantage they still have LoongArch. If they go all in on RISC-V they could easily get fucked or bullied into submission, that's my view anyways.
There's no danger in using RISC-V -- if the official standard is compromised somehow, China can just make their own "fork". I think it's more likely just a business decision by Loongson. Unless it's replaced, it'll likely become an open standard eventually
Good point, I didn't think of that! Either way, I'm quite happy to see more general purpose RISCs emerge. At this point I'm just really sick of dealing with Intel's CISC crap lol.
