Hi, I had earlier written a stack analysis tool for mspgcc compiled
programs for my own use.
I put it up on google code for anyone to download and use.
The link is http://code.google.com/p/stkchk/
What can it do?
Analyze the call tree of a program and report the stack usage of a function
(by default "main") and its children.
Distinguish between direct function calls and indirect function calls (via
function pointers).
Indirect calls can be resolved if the user provides addition information on
the command line.
Detect recursion both direct (f() -> f()) and indirect (f()-> g()->f()),
and report it.
Thanks
RJ
