If I've read correctly, RISC-V is a > modular architecture with optional features (hard float, MMU..) So, it's using the RV64IMFD subsets. When the sources don't contain float or double arithmetic the FD subsets aren't used, but I do rely on the existence of M for any multiplications and divisions (by non-power-of-2).
