I can also do that. The asymmetry between print_frames/print_inline_frames is a bit weird.

One more needed simplification I noticed:

i > 1 ? "inline" : ...
can just be replaced with "inline"

The prior lines have a guard that skips the scope if dwarf_tag(scope) != DW_TAG_inlined_subroutine, hence anything printed through that invocation is already known to be an inlined invocation.
