------- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18412
