These are changed to the ordinarily order such as `op src1 src2 dest`. +- **Bytecodes**: Bytecodes of virtual machines are expressed by three address codes ordered as `op dest src1 src2`. The order is changed to the ordinary one `op src1 src2 dest`. -- **Bytecode optimisation**: +- **Bytecode optimisation**: The following is introduced: - A sequence `OP_EQI_RO reg` `OP_JMPEQ0_R0 pc` is optimised into a code `JMPNEQ0 reg pc`. - By introducing a bytecode `OP_INC src dest`, a code `OP_ADDI src $1 dest` and a code`OP_ADDI $1 src dest` are optimised into `OP_INC src dest`. - By introducing a bytecode `OP_DEC src dest`, a code `OP_SUBI src $1 dest` is optimised into `OP_DEC src dest`. -- **Intermediate code for blocks**: To show areas of blocks, an intermediate code `OP_BEGIN_BLOCK` is introduced. Copy Propagation for `OP_LOAD` and `OP_LOADI` is performed until the next `OP_BEGIN_BLOCK` occurrence. +- **Intermediate code for blocks**: To show areas of blocks, an intermediate code `OP_BEGIN_BLOCK` is introduced.
