This field is built as a gcov_unsigned_t but declared
as a plain "unsigned", which breaks all int16 targets:
/* n_functions */
field = build_decl (BUILTINS_LOCATION, FIELD_DECL, NULL_TREE,
get_gcov_unsigned_t ());
DECL_CHAIN (field) = fields;
fields = field;
Assuming we want to support more then 65536 functions on int16
targets, how about this semi-obvious patch?
