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

...o Dwarf 5, and the next GDB. The framework is a set of GCC like gdwarf[2,3,4,5] flags. I can see cases where compatibility is 2,3 or 2,3,4, so maybe the flag is a number to allow <=3 tests, have to sleep on that. This flag must go to the backend. Then the patch will change the conditional for DW_FORM_flag_present that caused the problem back to the old DW_FORM_flag when -gdwarf2 or 3 is set. In the future, there is a now a place to address compatibility issues that come up. ---- Monitoring this with GDB Testsuite as Jenkins or Buildbot would be a good idea. 20K+ tests are difficult to duplicate.

Hi, I'm trying to achieve the following: - I have a global variable BaseAddress that holds the base address of a contiguous dynamically allocated memory block. - I have a number of logical variables of different types that are mapped on certain address ranges inside the memory block pointed to by BaseAddress. The offset and the size of each such logical variable inside the memory block are

My GDB Testsuite runs have been failing more tests, and now an internal test has started failing on some missing dwarf 3 records. Changing compile flags to emit dwarf 2 didn't help. In the past there has been some effort to pass GDB Testsuite, including Dwarf 2 backwards compatibility. What is the plan/mechanism for maintaining Dwarf 2/3 compatibility? -- Rick Foos Qualcomm Innovation
