Hi Stumbled onto this due to dire shortage of ram and monitoring stack usage. To get an idea of whether it was enough, etc.
I'll try and put together sample code which replicates it but the scenario for now is: static void initialise(void) { char buf[50]; // some data // call a bunch of functions } int main(void) { initialise(); // bunch of stuff } Now, initialise() is only ever called once and therefore is optimised and included inline into main(). What I find is that space used by buf[] is never released from the stack. There may in fact be more since initialise() calls a whole bunch of other functions, some of which may or may not have variables on the stack and/or be one-off functions and as a result 'rolled-into' code that then forms main(). Given my constrained setup, its critical that this stack space is freed. Anyone come across this? Is it a known issue? -- Cheers, Dale. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
