about

nx_riscv_codegen.nx -- SOVEREIGN RISC-V backend, RUNG 4: IR -> RISC-V CODEGEN. Now on the GENERAL nx_riscv_lib (shared encoders, lower w/ regalloc+instr-sel, build_header, emulator) -- only the qmul IR + tests are local. Lowers qmul(2.0,3.0)=(a*b)>>16 then >>16 (integer part), runs it; retargets when the IR input changes. T1 lowers to 8 words ending in ecall. T2 run -> exit 6 (2.0*3.0 int part). T3 (teeth) input 2.0->4.0 -> exit 12. expect_exit: 0 Sovereign: nx_riscv_lib (+ nx_syscalls).
