/* The purpose of this program is to use gdb or lldb to watch a
|
|
region of memory get overwritten first with a byte, then a short,
|
|
then an int and finally with a long.
|
|
|
|
As can be seen, the program produces no output of its own. Rather,
|
|
use of a debugger is needed.
|
|
|
|
The gdb command to examine the memory located at "ram" is:
|
|
x/xg $x1
