Back in 2017, XC16 failed to perform correctly the (simple) math in this loop (as opposite to C30):
...as written above (!) unrolling the loop did the trick. I opened a Ticket @microchip, but after 1month ping-pong of useless replies (...) I let it go. That's the way it goes...
PS: C30 v.325 or 31 was being used on a PIC24FV32 while XC16 current version at the time was being used on a PIC24EP and/or PIC24FJ..GA - I've not retested with latest updates. Variables are declared float.
#ifdef __XC16 // il porcodidio di XC16 non fa la somma (con O1) ..., 5.10.17
ValueF[0]+=gradient[0];
CalcTriac(0,ValueF[0]);
ValueF[1]+=gradient[1];
CalcTriac(1,ValueF[1]);
ValueF[2]+=gradient[2];
CalcTriac(2,ValueF[2]);
#else
for(i=0; i<3; i++) {
ValueF[i]+=gradient[i];
CalcTriac(i,ValueF[i]);
}
#endif...as written above (!) unrolling the loop did the trick. I opened a Ticket @microchip, but after 1month ping-pong of useless replies (...) I let it go. That's the way it goes...
