DEVICE FOR OPTIMIZING MACHINE LANGUAGE INSTRUCTION SEQUENCE OR ASSEMBLY LANGUAGE INSTRUCTION SEQUENCE; AND COMPILER FOR CONVERTING SOURCE PROGRAM DESCRIBED IN HIGH-LEVEL LANGUAGE TO INSTRUCTION SEQUENCE OF MACHINE LANGUAGE OR ASSEMBLY LANGUAGE

摘要

PROBLEM TO BE SOLVED: To reduce a number of restrictions due to definition instructions of an indirect address designating type in the conventional assembler and machine language level optimizing system. ;SOLUTION: When a resource allocating part 11 allocates internal variables generated by a compiler to the machine resources of a register, a memory, etc., and an assembler code generation part 18 outputs an instruction sequence, an another-name accessability analyzing part 19 registers the presence/absence of the possibility of another-name access in an memory access instruction included within the instruction sequence to allocation resource information 14. An assembler optimizing part 20 refers to the information 14 and optimizes in the assembler level to reduce the size or the executing time of the instruction sequence.;COPYRIGHT: (C)1999,JPO
