...d some shape analysis.
This summer however, I plan to create an "optimization" that
automatically fixes memory leaks in programs - obviously only those
that can be fixed with the available information, for example:
int addAndFree(int *x, int y) {
y += *x; free(x);
return y;
}
int functionCalled10MTimesInSomeLoop(int index, int data[]) {
int *x = (int*)malloc(sizeof(int));
if(index < 3) { // do stuff with x, index and data
*x = data[index];
return addAndFree(x,index);
} else
return -1;
}
the function would not leak if that free instruction was copied in
bb2: before ret (see bellow: -O4 versio...
