49 | ||
50 | Regardless of the language, GDB represents multidimensional | |
51 | array types the way C does: as arrays of arrays. So an | |
52 | instance of a GDB array type T can always be seen as a series | |
53 | of instances of TYPE_TARGET_TYPE (T) laid out sequentially in | |
54 | memory. | |
55 | ||
56 | Row-major languages like C lay out multi-dimensional arrays so | |
57 | that incrementing the rightmost index in a subscripting | |
58 | expression results in the smallest change in the address of the | |
59 | element referred to. Column-major languages like Fortran lay | |
60 | them out so that incrementing the leftmost index results in the | |
61 | smallest change. | |
62 | ||
63 | This means that, in column-major languages, working our way | |
64 | from type to target type corresponds to working through indices | |
