有一个新的字符可以用于字节码中的标识符中(“ + ”)，一些处理类引用的指令发生了修改，还有一个不同的方法用于处理合成组件。

There's a new character usable in identifiers within the bytecode (" + "), a modification to a pair of instructions to work with class references, and a different approach to synthetic components.

因此，执行字节码指令要比访问语法树节点快得多。

Therefore, executing a bytecode instruction is much faster than visiting a syntax tree node.

此过程将生成方法的一个内部表示，该表示与字节码不同但是其级别要高于目标处理器的本地指令。

The process involves generating an internal representation of a method that's different from bytecodes but at a higher level than the target processor's native instructions.
