Given the following variable declaration...
Www : Wide_String := "12345";
... this patch allows the following assignment to work:
(gdb) set variable www := "qwert"
Without this patch, the debugger rejects the assignment because
the size of the array elements are different:
(gdb) set www := "asdfg"
Incompatible types in assignment
(on the lhs, we have an array of 2-bytes elements, and on the rhs,
we have a standard 1-byte string).
gdb/ChangeLog:
* ada-lang.c (ada_same_array_size_p): New function.
(ada_promote_array_of_integrals): New function.
(coerce_for_assign): Add handling of arrays where the elements
are integrals of a smaller size than the size of the target
array element type.
gdb/testsuite/ChangeLog:
* gdb.ada/set_wstr: New testcase.
