Title:
DEVICE, METHOD FOR COMPILE AND RECORDING MEDIUM RECORDING COMPILER
Document Type and Number:
Japanese Patent JP3237591
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To generate a target program with high execution efficiency by generating an intermediate text, for which a register moving instruction is not used as little as possible, concerning a computer with which the kind of registers to be allocated to data to be respectively used by plural input operands in the intermediate text is limited corresponding to the position of respective input operands in the intermediate text.
SOLUTION: An intermediate text generating processing part 10 generates plural intermediate texts 50 by converting a source program 40, an operand position exchange part 22 exchanges the positions of respective input operands in the respective intermediate texts 50, a register selecting part 23 allocates registers to the data to be used by the respective input operands in the respective intermediate texts 50, adds the information of registers to the intermediate texts 50 and stores the information of correspondent relation between these data and registers in a register managing table 21 and a target program generating processing part 30 generates the target program based on the plural intermediate texts to which the information of registers is added.
