[Bug fortran/41227] COMMON block, BIND(C) and LTO interoperability issues

[burnus at gcc dot gnu dot org]

------- Comment #1 from burnus at gcc dot gnu dot org  2009-09-14 21:05 -------
In any case gcc/dwarf2out.c needs to be modified. It currently has:

fortran_common (tree decl, HOST_WIDE_INT *value)
{ [...]
  if (TREE_CODE (val_expr) != COMPONENT_REF)
    return NULL_TREE;

However, one needs to create a DW_TAG_common_block which contains a
DW_TAG_variable.
