Re: to reduce footprint

[Lin George]

Thanks Michael! I am interested why using printf will make footprint/malloc 
will make footprint larger? I think they are just some functions from other 
shared libraries, which will only have a link/address in the module which 
invokes them -- they are not inline functions. Why using printf and malloc will 
make footprint larger?


regards,
George

This would probably be better sent to the gcc-help mailing list.

Debug information generally does not take any memory space.

There are optimizations, which other people have mentioned.

But the best way to have smaller footprint is to have less code.
For example, if you are doing simple I/O operations, you might
low level I/O routines like getc or puts, rather than much larger
functions like printf.  Avoiding malloc also reduces footprint.
