2. Fortran Type Support 2.1 CHARACTER Intrinsic Type
There is no analog in C for the Fortran CHARACTER type. The Fortran
CHARACTER type maps to the DWARF tag, DW_TAG_string_type. We have added a
new named DI to LLVM to generate this DWARF information.
!21 = !DIStringType(name: “character(5)”, size: 40)
This produces the following DWARF information.
DW_TAG_string_type:
DW_AT_name: “character(5)”
DW_AT_byte_size: 5

...ne class.
I agree that the array stuff needs to be designed with an eye to handling how other languages do arrays, and leverage the common aspects. Several languages have runtime-sized arrays and it would be nice to handle them all the same way.
However the CHARACTER type probably does want to be DW_TAG_string_type rather than an array. COBOL also has strings as a fundamental type.
I guess we'll have to learn what all the Fortran array stuff actually means now…
