compiler另一种编译程式的编译程式 YACCcompiler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] A program that converts another program
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}.
