RISC-V was OK before the 1.1 spec. Version 1.1 is self-sabotaged by the RISC-V team, in such a way that you can't create a cycle-accurate software emulator running at reasonable speed. The dirty deed is in changes in the instruction encodings, multiple bit shuffling instructions in the emulator are now required to decode some 1.1 insns.
To me, this indicates that the RISC-V team has bad intentions, and I dropped RISC-V for this reason.
