compiler 音标拼音: [kəmp'ɑɪlɚ] n. 编辑者 编辑者 compiler 编译程式; 编译器 compiler 另一种编译程式的编译程式 YACC compiler 编译器 编译程式 compiler n 1: a person who compiles information (as for reference purposes) 2: (computer science) a program that decodes instructions written in a higher order language and produces an assembly language program [synonym: {compiler}, {compiling program}] Compiler \Com*pil"er\ (k[o^]m*p[imac]l"[~e]r), n. [OE. compiluor; cf. OF. compileor, fr. L. compilator.] 1. One who compiles; esp., one who makes books by compilation. [1913 Webster] 2. (Computers) a computer program that decodes instructions written in a higher-level computer language to produce an assembly-language program or an executable program in machine language. [WordNet 1.5 PJC] from some {source language} (or {programming language}) to {machine language} (object code). Some compilers output {assembly language} which is then converted to {machine language} by a separate {assembler}. A compiler is distinguished from an assembler by the fact that each input statement does not, in general, correspond to a single machine instruction or fixed sequence of instructions. A compiler may support such features as automatic allocation of variables, arbitrary arithmetic expressions, control structures such as FOR and WHILE loops, variable {scope}, input/ouput operations, {higher-order functions} and {portability} of source code. {AUTOCODER}, written in 1952, was possibly the first primitive compiler. {Laning and Zierler}'s compiler, written in 1953-1954, was possibly the first true working algebraic compiler. See also {byte-code compiler}, {native compiler}, {optimising compiler}. (1994-11-07)
