Since the c51 compiler does not support the recursive call of a function is there any way to find out on which address location the function which is to be called as a recursive is located?
That is, is there any way to implement the recursive call funtion in a similar way of a software reset i.e just call like this ,
((void (code *) (void)) 0x0000) ();
***Warning L13: RECURSIVE CALL TO SEGMENT SEGMENT : ?PR?_?DEVICE_ID?MAIN CALLER : ?PR?TOTAL_DEVID?MAIN
This is the warning message. Actually the reentrant function is Device_ID().My function look like this,
void Device_ID(void) reentrant { . . func1(); . . func2(); . . }
void func1(void) //this is not reentrant { . . }
void func2(void) //this is not reentrant { . . func3(); . . }
void func3(void) { . . Device_Id(); //in this function only i call the //reentrant function . . }
I already told that the setting i did in the startup.a51.
Now what should i do?
If you call other functions from your reentrant function, they should be declared reentrant, too (unless you really know what you're doing) - otherwise, there could be multiple instances of the called functions active at the same time.
