一种基于GDAG和寄存器状态的代码生成技术

Target code generation technique based on GDAG and register states

在通常的DAG基础上增加了代码活跃信息(记为GDAG),给出了基于GDAG和寄存器状态的代码生成技术,并且在产生GDAG的目标代码时利用了代码活跃信息和寄存器状态信息,从而更加有效地利用了寄存器,达到了进一步提高目标代码运行速度的目的。

A target code generation technique based on GDAG and register states was presented. Active information was added to the general DAG, which was denoted as GDAG. Active information together with register states were used during the target code generation. Since information about registers is utilized effectively target codes of high running speed can be generated.
