llvm-dwarfdump currently outputs the offset of each DIE relative to the entire debug_info section. But type/DIE references within a unit are relative to that unit. Should we emit unit-relative offsets instead? I've prototyped this and end up with output something like this: 0x00000051: DW_TAG_base_type [24] DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000051] =

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

I recently upgraded a codebase to use LLVM 3.9.0, up from 3.7.1. All seems to work well, except that I am unable to generate debug information. However, if I run objdump -g on the generated object file, it reports that the compile unit has no children: Contents of the .debug_abbrev section: Number TAG (0x0) 1 DW_TAG_compile_unit [no children] DW_AT_producer DW_FORM_strp

Are you perhaps not calling void Function::setSubprogram (DISubprogram * SP) http://llvm.org/doxygen/classllvm_1_1Function.html#a05a19abc8ee11d5909275d980efa1670 ? -- adrian > On Nov 18, 2016, at 8:46 AM, David Blaikie <dblaikie at gmail.com> wrote: > > (+Adrian who might have some more context here) > > Generally I'd suggest looking at Clang's code to see how

I have recently been modifying the DWARF parser and have more patches planned and I want to be able to add unit tests that test the internal llvm DWARF APIs to ensure they continue to work and also validate the changes that I am making. There are not many DWARF unit tests other than very simple ones that test DWARF forms currently. I would like to expand this to include many more tests. I had

I'm trying to write a llvm pass to add debug info into a non-debug-info bitcode file. I have been read http://llvm.org/docs/SourceLevelDebugging.html. And I use DIBuilder to produce the debug metadata. I know I can't get all information form ir code . So I add some manual info as test data. After executing my pass, I can find debug info metadata in my generated bitcode. Those metadata

Hi, I am trying to execute a simple hello world program compiled like so: path/to/compiled/clang -o test --target=aarch64-linux-gnu -march=armv8.5-a -fsanitize=hwaddress --sysroot=/usr/aarch64-linux-gnu/ -L/usr/lib/gcc/aarch64-linux-gnu/10.1.0/ -g test.c However, when I look at the disassembly, there is an unknown instruction listed at 0x2d51c: 000000000002d4c0 main: 2d4c0: ff c3 00 d1

The enclosed patch contains a number of wording and clarity improvements to BitCodeFormat.html, and documents in detail the record types used within MODULE blocks. I plan to continue documenting the rest of the record types, but I wanted to submit patches in reasonably-sized pieces. -Peter S.
