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

Yes, I think it works. There are two ways to edit the .debug_abbrev section. i) Edit the "Attr:" and

...out, the support for generating DW_FORM_implicit_const is there, but I could not make out the DWARF attributes for which this form is being generated currently. Are there any attributes for which this form is generated currently ? Gcc typically generates this form for a bunch of attributes like: DW_AT_decl_file, DW_AT_decl_column, DW_AT_accessibility, DW_AT_defaulted, DW_AT_byte_size, etc Any pointers are deeply appreciated.

Hi I'm using llvm-5. Browsing the source of llvm-dwarfdump and trying it on some shared libraries, I see I can print the debug info (assuming it exists). For some function, I'm wondering if there's a short cut to prettyprinting the signature of a function in the library? I think, looking at the output, that enough information exists but it seems to involve looking at the subprogram

...llvm-dwarfdump more developer friendly. There are quite a few features in Darwin’s dwarfdump that we find quite useful and that we would like to contribute to llvm-dwarfdump. I have started by augmenting the -debug-dump=info output: - Symbolic names for attribute values - Line table lookups for DW_AT_decl_file - Annotate DW_AT_specification with the target DIE’s name - DWARF expression pretty-printing With these enhancements, the debug_info dump is nearly always sufficient and the user rarely needs to go and decode himself the referenced content of other debug sections. There will be more work by me...
