## Scope
Support for the RV32I base ISA and RV32M extension are planned and well underway. Support for other ISAs in the original riscv-formal such as RV32C and their 64-bit counterparts may also be added in the future as time permits.
The RV32I, RV32M, RV64I and RV64M ISAs are currently implemented but yet to be fully tested. Support for compressed instructions may be added in the future as time permits.
