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

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

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

Were those errors from trying to dump the linked executable, and not errors that were produced by the linker itself? Yes, as mentioned earlier I was able to generate final executable but it
