The `rv32ui` and `rv64ui` TVMs are integer-only subsets of `rv32u` and `rv64u`
respectively. These subsets can not use any floating-point instructions (major
opcodes: LOAD-FP, STORE-FP, MADD, MSUB, NMSUB, NMADD, OP-FP), and hence cannot

TVMs are useful for initial processor bringup and to test simpler
implementations that lack a hardware FPU.
