about

nx_rv64_jit_w_gate.nx -- GATE: the JIT now compiles *W (32-bit word) ops, so REAL `int` loops accelerate. Before this, jit_compile lacked ADDIW/ADDW/SUBW/MULW/SLLIW/SRLIW/SRAIW -> real compiled int loops (i++ = addiw) NEVER JIT'd (the realc gate showed 0 loops JIT'd). A *W-heavy loop (sum of i*i for i in 1..K using mulw/addw/addiw + a 32-bit branch) now JITs: T1 result == the golden interpreter (correctness, incl. 32-bit sign-extension), T2 it actually compiled + ran native, T3 measurably faster. Uses the sovereign assembler (which emits *W). expect_exit: 0
