51 | Regardless of the language, GDB represents multidimensional | |
52 | array types the way C does: as arrays of arrays. So an | |
53 | instance of a GDB array type T can always be seen as a series | |
54 | of instances of TYPE_TARGET_TYPE (T) laid out sequentially in | |
55 | memory. | |
56 | ||
57 | Row-major languages like C lay out multi-dimensional arrays so | |
58 | that incrementing the rightmost index in a subscripting | |
59 | expression results in the smallest change in the address of the | |
60 | element referred to. Column-major languages like Fortran lay | |
61 | them out so that incrementing the leftmost index results in the | |
62 | smallest change. | |
63 | ||
64 | This means that, in column-major languages, working our way | |
65 | from type to target type corresponds to working through indices | |
66 | from right to left, not left to right. */ | |
