RISC-V ISA (RV64GC + vector)
7 done - 1 partial - 5 to build
Why it matters
RISC-V RV64GC + vector: base ISA, M/A/F/D/C, privileged/CSR model, Sv39 MMU and a vector unit, plus the breadth still to build (RV32, B, H-mode, RVV 1.0, Sv48).
What
Build out the 'RISC-V ISA' capability area: 13 stories spanning 5 not-yet-built, 0 stubbed, 1 partial and 7 already-implemented (hardening) features.
