[PUSHED,07/11] gdb/fortran: Expand the set of types that support (kind=N)
Commit Message
Expand the number of types that can be adjusted with a (kind=N) type
extension.
gdb/ChangeLog:
* f-exp.y (convert_to_kind_type): Handle more type kinds.
gdb/testsuite/ChangeLog:
* gdb.fortran/type-kinds.exp (test_cast_1_to_type_kind): New
function.
(test_basic_parsing_of_type_kinds): Expand types tested.
(test_parsing_invalid_type_kinds): New function.
