Its frontend interface is based on the tree structure . additionally , the hook mechanism connects the language - specific front end and the gcc main body . 2 Gnu前端接口:以樹(shù)結(jié)構(gòu)作為語(yǔ)言無(wú)關(guān)的接口,通過(guò)回調(diào)機(jī)制,將gcc前端同編譯主體聯(lián)系起來(lái)。
At last , the paper has an emphasis on the developing of software of the whole control system which include the procedure of interface , control procedure of system , database developing and network function 最后,重點(diǎn)介紹了整個(gè)系統(tǒng)的軟件設(shè)計(jì)方法,包括前端接口程序、系統(tǒng)控制程序、成品料溫專家控制系統(tǒng)、數(shù)據(jù)庫(kù)設(shè)計(jì)及網(wǎng)絡(luò)功能等。
After listing some requirements of embedded system development toolschain , this paper gives the advantage of using gnu based tools , and some information about gcc architecture . through those analyses , we expected to know how we can do something to have the gcc compiler to fit our project . gcc has architecture as follow : 1 本文從嵌入式系統(tǒng)開(kāi)發(fā)工具鏈的需求出發(fā),考查gnu工具鏈的特點(diǎn),集中在對(duì)gcc的優(yōu)化流程,前端接口,后端接口等三個(gè)方面結(jié)構(gòu)特征的總結(jié)分析, gnu結(jié)構(gòu)上存在如下特征: 1
