--- Comment #12 from David Binderman <dcb314 at hotmail dot com> ---
After a couple of hours of reduction, I have:
typedef signed __int8_t;
typedef char __uint8_t;
typedef int __int16_t;
typedef unsigned __uint16_t;
typedef signed __int32_t;
typedef long __int64_t;
typedef long __uint64_t;
typedef __int8_t int8_t;
typedef __int16_t int16_t;
typedef __int32_t int32_t;
typedef __int64_t int64_t;
typedef __uint8_t uint8_t;
typedef __uint16_t uint16_t;
typedef __uint64_t uint64_t;
int64_t
safe_lshift_func_int64_t_s_s(int64_t left, int right )
{
return
left < 0 || right < 0 || right >= 32 || left ?
:
left < right;
}
#pragma pack(1)
struct S0 {
unsigned f3 : 14;

int main ()

Reduction continuing.
