I noticed your attempt to optimize NutEnterCritical().
If there are more pairs NutEnterCritical() / NutExitCritical(), and
these macros are using a memory variable, this generates more local
However these are only on stack and there are not so many of them, our
compiler does not optimize their usage.
What about to use something like NutUseCritical() and to use it at the
beginning of each function where NutEnterCritical() is used ?
#define NutUseCritical() int temp_
We solved this by using a register variable.
But anyhow, once there is an opportunity to modify this long time
untouched source codes ...
