I don't need an instruction that loads low 32-bit. It already exists. It's called 'mov'. I'm going to try encoding: insn[0].code = LD | IMM | DW insn[1].code = 0 zero is invalid opcode, so it's your 'continuation'. and it is still single 16-byte instructions without any interpreter overhead.
Works for me. --Andy
