--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
ICE's in vectorizable_load, too:

markus@x4 linux % cat vsyscall_gtod.i
struct {
  int tz_minuteswest;
  int tz_dsttime;
} a, b;
void fn1() {
  b.tz_minuteswest = a.tz_minuteswest;
  b.tz_dsttime = a.tz_dsttime;
}

markus@x4 linux % gcc -mno-sse -mno-mmx -O3 -c vsyscall_gtod.i
vsyscall_gtod.i: In function âfn1â:
vsyscall_gtod.i:5:6: internal compiler error: in vectorizable_load, at

 void fn1() {
