           Summary: arm-linux-android-eabi: error in backend: Can't handle
                    live physical register dependency!

test case by csmith/creduce. 
The test case is a bit overly synthetic, so I am not sure if this reports is
very useful. Still filing just in case. 

#pragma pack(1)
struct S1 {
  int:24;
  int f2:23;
  int:20;
  volatile int f4:21;
  int :29;
  int :31;
  int f8:27;
};
static const struct S1 a;
void bar(int);
void foo () {
  bar (a.f2);
  bar (a.f4);
  bar (a.f8);
}
