Until now Mono's code generation engine was based on a tree Intermediate Representation (IR) of the code.

直到现在Mono的代码生成引擎都是基于树状的代码中间表现形式(Intermediate Representation, IR)。

Strictly speaking, the AST (abstract syntax tree) is also an IR (intermediate representation) - since it is not quite the source, and not quite the target language.

严格说来，AST(抽象语法树)也是一种IR——因为它既不是源代码，也不是目标语言。
