我们在构建一个新的编译器和中间表述，这样在我们生成JVM字节码前更容易做一些优化。

We've continued building a new compiler and intermediate representation that will be easier to optimize before we generate JVM bytecode.

这很方便，如果不支持的话，编译器会一次生成基本兼容的字节码。

It is convenient, if unsupported, and the compiler generates mostly compatible bytecode in a single pass.

字节码增强器使用classworking技术来修改由JD k 5.0编译器生成的类文件，使得这些类可以用于旧版J VM。

The bytecode enhancer USES classworking techniques to modify the class files generated by the JDK 5.0 compiler, making these classes usable with older JVMs.
