It's not strictly required to have it explicitly named. Our implementation allocates a COMMON block as an "untyped" block of memory and each subprogram can, of course, remap the storage units to its own list of variable names. The DW_TAG_common_block does require a DW_AT_location, and the !DIGlobalVariable fulfills that requirement.
