> Not to defend CPP-copy-paste, but MIPS has always been an open architecture (it is even open source now, you can get CPU verilog code from them).
I don't know that it has always been completely open. They have had licensees in the past, and it has been opened then closed at least once in the past, by the looks.
At any rate I don't really know what the status of the MIPS architecture is or its owners' relationship with the LoongArch people. I'm not suggesting they are in breach of copyright or any private agreements with them.
But it really is just MIPS. They tidied up a few minor things like delay slots, and adding some basic vector stuff, and tweaked instruction encodings. Then rebranded the whole thing and did copy-paste jobs on large swaths of code when submitting their architecture "ports".
