[Solved] Debug symbols with -gsplit-dwarf better then with -gn ?

Oolite (opensource remake of Elite) devs & users are discussing how to improve debugging options in https://github.com/OoliteProject/oolite/issues/586

One of the options mentioned is using -gsplit-dwarf to create .dwo files which will then be combined into .dwp files.
gcc, llvm/clang,  gdb, lldb and debuginfo.d  appear to support both dbg & dwp formats.

What do you see as pro & cons of these methods ?

Could archlinux packages be build with -gsplit-dwarf or would that require changes in pacman/makepkg ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

It's not clear why format of debug symbols is chosen by upstream. I think build system should be able to generate any format that compiler support, so user or downstream can configure it with compiler options while compiling or building a package.

Upstream provides binary flatpaks & appimages for download and felt the need to add debug symbols to them.
Since the compiling for those binaries is done by upstream they needed to set something .

The option chosen was -ggdb3 as both -gn & -gsplit-dwarf didn't work for all usecases.

Marking as solved.
