--- Comment #11 from Mark Wielaard <mark at klomp dot org> ---
With gcc (GCC) 11.0.0 20210225 on arm64 (which defaults to DWARF5) this
produces:
[ 179] variable abbrev: 23
abstract_origin (ref4) [ 1ec]
location (sec_offset) location list [ 30]
GNU_locviews (sec_offset) location list [ 2e]
[ 1ec] variable abbrev: 7
name (string) "f16"
decl_file (implicit_const) audiovisualwaveform.ii
(1)
decl_line (data1) 8
decl_column (data1) 10
type (ref4) [ 1f9]
[ 1f9] base_type abbrev: 2

[ 0] implicit_value: 2 byte block: 00 04
base_address 0x179a006343404
0x000179a006343404
end_of_list
Note that it isn't technically invalid DWARF, but the base_address is highly
unlikely to be correct.
