[avr-gcc-list] Stack usage profiling for function calls.

[Mattias Svensson]

I Wonder if there is any tool available that takes a function written in 
C and traces the stack usage of subsequent calls to other functions.

Today I read the assembler listing file ".list" output from avr-gcc and
trace how many registers are pushed onto the stack for each function, it 
works but is kind of time consuming...

Maybe I have missed some nice switch for avr-gcc that generates what I want.

It is also possible to make a mem dump and see how deep the stack has 
grown since all RAM is zeroed at init. But it is not accurate enough, 
some worst case scenarios are easily missed.
