/* * Array type with lower & upper bounds.
|
|
|
|
Regardless of the language, GDB represents multidimensional
|
|
array types the way C does: as arrays of arrays. So an
|
|
instance of a GDB array type T can always be seen as a series
|
|
of instances of T->target_type () laid out sequentially in
|
|
memory.
|
|
|
|
Row-major languages like C lay out multi-dimensional arrays so
|
|
that incrementing the rightmost index in a subscripting
|
|
expression results in the smallest change in the address of the
|
|
element referred to. Column-major languages like Fortran lay
|
|
them out so that incrementing the leftmost index results in the
|
|
smallest change.
|
|
|
|
This means that, in column-major languages, working our way
|
|
from type to target type corresponds to working through indices
|
|
from right to left, not left to right. */
