All of this information is contained in the DWARF debug info that you must generate. Are you generating DWARF? If not, you will need to. If so, please attach an example program that contains DWARF and specify which function you are having trouble getting variable information for.

Hi, all I ported llvm backend and lldb recently. Both tools can basically work. lldb is able to debug programs in asm style and frame unwinding is OK. But "frame variable XX" does not work because lldb is not able to determine the address of XX from debug info. Can someone give any clue? Thanks in advance. -- 杨勇勇 (Yang Yong-Yong) -------------- next part -------------- An HTML
