But I wanted to make sure I really get that version of debug info, so I tried "info source" in GDB. But that command doesn't tell the version of DWARF2. Is there a GDB command which does? I also tried "objdump --dwarf=info" (Binutils 2.29), but that says the DWARF2 version is 4. So now I'm confused. Can someone please tell me how to verify the version of DWARF2 I get with that GCC switch? Thanks.
