- Implement opStack protection: Use register %ebx for scaled indexed addressing mode to access opStack, make opStack push/pop operate on %bl portion only
- Add a third pass to VM compilation for computation of jump address offsets, removing the need to dereference into vm->instructionPointers[] for every call/jump - Make use of 0F opcode prefix relative jumps - Call Com_Memcpy for OP_BLOCK_COPY - Fix several missing range checks for vm->dataBase memory access
