Some of you may be aware that gplink can create stack sections at link
time. This is accomplished using the stack directive in a linker
script.
STACK size=<value>
A section ".stack" of size <value> is created. A symbol _stack is also
created. It points to the first address (lowest value) of the stack.
mplink behaves in the same way.
gplink has two extensions. The first is that the stack can be specified
on the command line, -t <value> or --stack <value>. This feature allows
stacks to be used with modifying the provided linker scripts.
The second extension is new. A _stack_end symbol is added. This symbol
points to the end of the stack. This will help with downward growing
stacks and could be used for detecting stack overflow. Keep in mind
that using this extension will make your project incompatible with
mplink.
