--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Here is a better testcase:
#include <stdio.h>

int a;
long b;
static inline long c(unsigned d) { 
    return d; 
}
static inline void e(int d) { 
    a = d; 
}
int main() {
  b = 0;
  for (; b < 1; b = c(b - 90) + 90 + 1)
    ;
  e(b >> 2);
  printf("%d\n", a);
  if (a != 1073741824)
    __builtin_abort();
}
