RISC-V instruction encoding library. The following instruction sets are implemented at the moment:

• RV32I base instruction set
• RV32M standard extension

No compressed 16-bit instructions yet. The library is in its early days, so there is more to come.

The code is based on the official RISC-V documentation:
