RISC-V support

RISC-V (pronounced "risk-five") is an open-source instruction set architecture (ISA) based on established reduced instruction set computing (RISC) principles.

In contrast to most ISAs, the RISC-V ISA is free and open-source and can be used royalty-free for any purpose, permitting anyone to design, manufacture and sell RISC-V chips and software.

The instruction set is designed for a wide range of uses. It supports three word-widths, 32, 64, and 128 bits, and a variety of subsets. The subsets support small embedded systems, personal computers, supercomputers with vector processors, and warehouse-scale rack-mounted parallel computers.
