摘要

支配路径调度对支配树中的路径执行全局指令调度。与其他全局调度方法不同,支配路径调度不需要操作副本来保留程序语义。在典型超标量架构的有限测试套件中,支配路径调度产生的调度比单独的本地调度所需的周期少8.3%。

Dominator-path scheduling: a global scheduling method
Dominator-path scheduling performs global instruction scheduling of paths in the dominator tree. Unlike other global scheduling methods, dominator-path scheduling does not require copies of operations to preserve program semantics. In a limited test suite for a typical superscalar architecture, dominator-path scheduling produces schedules requiring 8.3% fewer cycles than local scheduling alone.
