------- Additional Comments From pinskia at gcc dot gnu dot org 2004-11-10 02:21 ------- Yes but it is not done right, note that if I do this: #include <stdio.h> #include <malloc.h>
static int size;
int main() {
int *x;
x = (int *)malloc(sizeof(int) * size);
for (int i = 0; i < size; i++)
x[i] = 7;
return 0;
}
We do vectorize the loop as we know that malloc does not modify size or even
return something which
can alias size.
