This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* * 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. */
