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
|
65 |
|
|
from right to left, not left to right. */

other places expect they can calculate addresses by adding it

some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8

One fix would be to make this field in bits (requiring that it

533 |

the other choice would be to make it consistently in units of

HOST_CHAR_BIT. However, this would still fail to address
