They just do not show the function names.

You can check how it looks like for Linux ELF binaries by: rm -f /tmp/bash-debugdata{,.xz};objcopy --dump-section .gnu_debugdata=/tmp/bash-debugdata.xz /bin/bash /dev/null;xz -dv /tmp/bash-debugdata.xz;readelf -Wa /tmp/bash-debugdata|less GDB should be able to extract .gnu_debugdata even from PE32 binaries but I guess nobody has ever tested that. You are right that after the MiniDebugInfo feature has been approved for Fedora (*) it should be ported from find-debuginfo.sh even into mingw-find-debuginfo.sh. Therefore also in the compressed way, not just as plain symbols you suggest. Jan (*) Personally I do not agree with that but that does not matter here. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
