if I have this code : u8MyArray[10]; u8 * pu8FirstPointer; u8 * pu8Data; u8 u8Index; pu8FirstPointer = u8MyArray; while( u8Index <10) { *pu8FirstPointer = *pu8Data; pu8FirstPointer ++ ; pu8Data++; }
this code is supposed to copy the data to the array but polyspace doesn't get it ,why?

With the following code, and with default options, Polyspace Code Prover (release R2013b) "got" it:
typedef unsigned char u8;
u8 u8Dest[10];
u8 u8Source[10];
void foo(void)
{
u8 * pu8FirstPointer;
u8 * pu8Data;
u8 u8Index = 0;
pu8FirstPointer = u8Dest;
pu8Data = u8Source;
while( u8Index <10) {
*pu8FirstPointer = *pu8Data;
pu8FirstPointer ++ ;
pu8Data++;
u8Index++;
}
}
So, would you please, contact www.mathworks.com/support with options used, realease and some explanation about what do you mean by "Polyspace doesn't get it".
