When a program is being debugged, a debugger interacts with the user and

130130 turns the stored debug information into source-language specific information.
131131 As such, a debugger must be aware of the source-language, and is thus tied to
132 a specific language of family of languages.

132 a specific language or family of languages.


The role of debug information is to provide meta information normally

  • LLVM optimizations gracefully interact with debugging information. If they

    181181 in the cases that would invalidate the debug info. This retains the LLVM
