That is by design. [eu-]readelf just shows the data of the given ELF file. That
is why .eh_frame is dumped, but .debug_frame isn't (if it isn't available as
separate .debug file).
(Note that -winfo doesn't work with eu-readelf:
I think it would be a surprising change if [eu-]readelf would now by default
start looking up auxiliary files to dump data from. But maybe it could do this
in a special mode. There is some precedent to do that with an extra mode, with
--debug-dump=info+ which does lookup split-DWARF (--debug-dump=info does not).
readelf: print split CUs when given --debug-dump=info+
To show the difference between "regular" CUs and split CUs print
offsets and references between { and } instead of [ and ].
When --debug-dump=info+ is given (implied by -w) instead of
--debug-dump=info any skeleton unit will be immediately followed
by the corresponding split compile unit (from the .dwo file).
Maybe we could extend the + notation to other sections which could be looked up
through some extension/auxiliary lookup mechanism from the main file?
