The DWARF3 standard (http://dwarfstd.org/Dwarf3.pdf) has the following. While
nice in principle, there are some potential problems (see PR 37738).

"3.3.4 Declarations Owned by Subroutines and Entry Points"
"The entry for a subroutine that includes a Fortran common block has a child
entry with the tag DW_TAG_common_inclusion. The common inclusion entry has a
DW_AT_common_reference attribute whose value is a reference to the debugging
entry for the common block being included (see Section 4.2)."
