Take the following Ada code:
package Test1 is
type TSS_Name_Type is new String (1 .. 2);
function Get_TSS_Name return TSS_Name_Type;
end test1;
package body Test1 is
function Get_TSS_Name return TSS_Name_Type is
begin
return " ";
end Get_TSS_Name;
end Test1;
--(reduced from exp_tss.ad?).
We get types which are not considered compatible by lang_hooks.types_compatible_p.
The types we get are
for the right hand side (the STRING_CST):
