摘要

软件流水线是在编译过程中提高循环的指令级并行性的一项重要技术。目前，LLVM编译器基础结构不提供这种优化，尽管存在一些特定于目标的实现。我们在LLVM框架内实现了一个高级的软件流水线方法。通过在LLVM的优化层中实现这一点，我们已经朝着目标独立的软件管道方法迈出了第一步。

High-level software-pipelining in LLVM

Software-pipelining is an important technique for increasing the instruction level parallelism of loops during compilation. Currently, the LLVM compiler infrastructure does not offer this optimization although some target specific implementations do exist. We have implemented a high-level method for software-pipelining within the LLVM framework. By implementing this within LLVM's optimization layer we have taken the first steps towards a target independent software-pipelining method.
