I am new to FreeRTOS, I am studying it by curiosity and eventually to port it to another platform. I was reading the code and found that there is a lot of “functions” that are defined, not declared. I suppose that it was made to reduce the function calls and the memory usage and generated instructios that are involved with. But this can also produce a bigger memory footprint… I didn’t make an exhaustive analysis function per function (if it is called one time in OS life cycle, it is perfect), I wonder if some of you did it ?
GCC compiler (and others) can optimize source code inlining some functions, and you can even suggest GCC to do it (inline keyword); the advantage is that GCC analyse all the application, FreeRTOS developers cannot predict that , but obviously there would compatibility issues in common files (like tasks.c). Maybe one could use a defined keyword ? like
#define INLINE inline
in GCC ?
