True, Swat cannot tell you your maximum stack usage. But you can check
your stack usage by using the Swat "backtrace" command. The -r flag to
bt tells Swat to print out the contents of a particular register for each
entry in the backtrace. Hence, you can use the following command at
those places in your code where you think you may be using a lot of stack
space (e.g., deeply nested routine/message calls, or passing large
parameters to routines):
[myApp:0] 37 => bt -rsp
to print out the stack pointer along with your backtrace. This will
show how your stack is used.
