Question

LLDB 有 convenience variables ？如果是这样，我该如何使用它们？如果没有，我可以使用类似的东西吗？

Answer 1

我终于自己弄清楚了。在 LLDB 中运行 help expr 你会看到:

User defined variables: You can define your own variables for convenience or to be used in subsequent expressions. You define them the same way you would define variables in C. If the first character of your user defined variable is a $, then the variable's value will be available in future expressions, otherwise it will just be available in the current expression.

所以 expr int $foo = 5 就是我想要的。
