Based on your behavior in this comment thread -- downvoting comments that give valid criticism of the RISC-V ISA -- I have to conclude that the reason the RISC-V folks chose not to reuse a patent-unencumbered ISA such as SH2 or MIPS32 (minus the unaligned load-store instructions) is simple vanity.
- bonzini 10y agoWhat does your comment add to the discussion, and what is the proof of what you are attributing to the user?
- baobrien 10y agoFor one, MIPS32 and SH2 are both 32-bit ISAs. Extending them to 64-bit would require just as much compiler re-working as building a new RISC ISA -- and it'd no longer be MIPS32 or SH2 anyway.
