Description

Regarding the evaluation of expressions, we analyzed the implementation in Swift. We found that lldb has implemented a Swift front-end compiler. When a user inputs an expression evaluation request in the command line while debugging a program, the Swift front-end compiler can correctly parse the Swift statements and accurately perform semantic restoration. I suspect this might be something that lldb cannot accomplish on its own by combining DWARF information and runtime. Therefore, does lldb need to have a built-in Swift expression parser? Is the Kotlin language also similar in this regard?

Research direction

The issue names LLDB's Swift front-end compiler, DWARF information, and runtime support but no source files or tests. Start by reviewing how LLDB handles Swift expression evaluation, then compare the needs of Kotlin/Native debugging and determine the scope of Kotlin expression support.
