There is an AVR tool called stacktool by John Regher that computes the
maximum stack depth by analyzing the binary code:
http://www.cs.utah.edu/~regehr/stacktool/
I haven't used it myself, but it is a very cool approach. (It isn't
ported to the MSP430.)
Static stack analysis tools used to be a fairly standard part of
embedded toolchains, but they seem to have more or less disappeared.
They always had a few limitations, in areas like recursion, but they
would know when they could not give a clean answer, and say so.
When the 8086 was shiny and new, I was programming for it in Intel's
PL/M86. That compiler and linker gave out a stack depth analysis at the
end of every list file. Other toolchains were more like the above
description of the AVR tool. Why have we gone backwards? :-\
