If you invoke the assembler via the compiler, with that flag it still
creates separate .o and .dwo files (via objcopy invocations as usual).
Whether that is useful depends on

Hi Nick,
I love your patch! Yet something to improve:
[auto build test ERROR on kbuild/for-next]
[also build test ERROR on asm-generic/master linus/master v5.10-rc2
next-20201104]
[cannot apply to tip/x86/core]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when
Modifies CONFIG_DEBUG_INFO_DWARF4 to be a member of a choice. Adds an
explicit CONFIG_DEBUG_INFO_DWARF2, which is the default. Does so in a
way that's forward compatible with existing configs, and makes adding
future versions more straightforward.
