    • A program development system in which the debugging apparatus is informed of all of the optimization processes which have been performed. A primitive storage unit stores record information for the optimization processes. The input unit receives an input of a variable and a value, or an input of a line where execution is to be halted. The primitive combining unit obtains record information showing the optimization processes. The code execution unit executes the execution code. The variable operation unit obtains the value of a variable based on relations between variables and resources. The output unit displays the obtained value of the variable. The line display unit displays the program or the generated execution code. The line information display unit displays, in line units, information relating to the optimization performed for each line, The operation-possible variable display unit displays, for each line, variables which can be set and referred to in the line. The optimization process display unit shows how the optimization affects each variable.
    • 一种程序开发系统,其中向调试装置通知已经执行的所有优化处理。 原始存储单元存储优化过程的记录信息。 输入单元接收一个变量和一个值的输入,或一个执行被停止的行的输入。 原始组合单元获得显示优化过程的记录信息。 代码执行单元执行执行代码。 可变操作单元根据变量和资源之间的关系获取变量的值。 输出单元显示获得的变量值。 行显示单元显示程序或生成的执行代码。 行信息显示单元以行单位显示与针对每行的优化相关的信息。可操作可变显示单元针对每行显示可以在该行中设置和参考的变量。 优化过程显示单元显示优化如何影响每个变量。
