Non-transitory computer-readable recording medium, assembly instruction conversion method and information processing apparatus

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

• storing a generation instruction in a storage area, where the generation instruction instructing a generation of an instruction sequence of a first instruction set that executes a processing equivalent to a first assembly instruction, the first assembly instruction being adjacent to a second assembly instruction and preceding the second assembly instruction, the first assembly instruction and the second assembly instruction belonging to a second instruction set;
• when a destination register of the second assembly instruction is different from a source register of the first assembly instruction corresponding to the generation instruction and a source register of the second assembly instruction is different from the destination register, determining a register of the second instruction set corresponding to the destination register as a temporary register in the instruction sequence;
• and
• generating the instruction sequence that uses the temporary register.

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

• acquiring an assembly file in which an assembly instruction of a first instruction set is described;
• when the assembly file includes a code specifying a first register, determining a second register of a second instruction set corresponding to the first register as a temporary register in an instruction sequence of the second instruction set that executes a processing equivalent to the assembly instruction;
• and
• outputting the instruction sequence in which the temporary register is set.

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

• calling multiple times a function that generates a machine language of a first instruction set that executes a processing equivalent to an assembly instruction of a second instruction set;
• storing a plurality of generation instructions in a storage area each time the function is called, each generation instruction instructing the generation of the machine language for each assembly instruction;
• identifying a first register that is not used by any of a plurality of assembly instructions corresponding to the plurality of generation instructions by referring to the storage area;
• determining a second register of the second instruction set corresponding to the first register as a temporary register in the machine language;
• and
• making the function generate the machine language that uses the temporary register for each generation instruction.

An assembly instruction conversion method for causing a computer to execute a process, the process comprising:

• storing each of a plurality of generation instructions in a storage area for each of assembly instructions, the generation instructions instructing the generation of instruction sequences of a first instruction set, each instruction sequence of the first instruction set executing a processing equivalent to each assembly instruction of a second instruction set;
• identifying a first register that is not used by any of the assembly instructions corresponding to the plurality of generation instructions by referring to the storage area;
• determining a second register of the first instruction set corresponding to the first register as a temporary register in each of the instruction sequences;
• and
• generating the instruction sequence that uses the temporary register.

An information processing apparatus comprising:

• a memory including a storage area;
• a processor coupled to the memory, and the processor configured to:
• store each of a plurality of generation instructions in the storage area for each of assembly instructions, the generation instructions instructing the generation of instruction sequences of a first instruction set, each instruction sequence of the first instruction set executing a processing equivalent to each assembly instruction of a second instruction set;
• identify a first register that is not used by any of the assembly instructions corresponding to the plurality of generation instructions by referring to the storage area;
• determine a second register of the first instruction set corresponding to the first register as a temporary register in each of the instruction sequences;
• and
• generate the instruction sequence that uses the temporary register.
