Compiler apparatus for optimizing high-level language programs using directives

Abstract

A compiler, which is a compiler that realizes program development in a fewer man hours, translates a source programwritten in a high-level language into a machine language program. This compileris comprised of: a directive obtainment unit that obtains a directive that a machine language program to be generated should be optimized; a parser unitthat parses the source program; an intermediate code conversion unitthat converts the source programinto intermediate codes based on a result of the parsing performed by the parser unit; an optimization unitthat optimizes the intermediate codes according to the directive; and a code generation unitthat converts the intermediate codes into the machine language program. The above directive is a directive to optimize the machine language program targeted at a processor that uses a cache memory.
