range anyway; I'm not sure about dbx.
It is well established, and widely used, that the type of the index,
unlike most types found in the stabs, is merely a type definition
(@pxref{Type Definitions}), not type information (@pxref{Stabs Format})
(that is, it need not start with @var{type-number}@code{=} if it is
defining a new type). According to a comment in GDB, this is also true
of the type of the array elements; it gives @samp{ar1;1;10;ar1;1;10;4}
as a legitimate way to express a two dimensional array. According to
AIX documentation, the element type must be type information. GDB
accepts either.
The type of the index is often a range type, expressed as the letter r
and some parameters. It defines the size of the array. In the example
below, the range @code{r1;0;2;} defines an index type which is a
