Dear LLVM devs, I've noticed that LLVM's assembler (and hence clang) doesn't generate debug data when assembling, even when run with "-g". Users can add their own CFI/line number data with assembler directives. But GDB ignores the line number data if you don't have a DIE in the .debug_info section which identifies the compilation unit. (I'm not an expert on GDB, but

Hello, Recently I found binaries produced with LLVM impossible to debug under Windows. This was probably related to the following bug: http://llvm.org/bugs/show_bug.cgi?id=13636 Asm generated from .ll files revealed that some offsets to debug information were incorrect: they were absolute instead of relative to their sections. Following patch seemed to have repaired the problem, so I'm

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

That happens because we create the subprogram below as a context to the “DW_TAG_typedef” that was created as a type to “DW_TAG_pointer_type” that was added to the retained type list because of the explicit cast to (T*). This is the code that creates DW_TAG_subprogram: DIE *DwarfUnit::getOrCreateSubprogramDIE(const DISubprogram *SP, bool Minimal) { ... // DW_TAG_inlined_subroutine may refer
