Here is the simplified version:
extern int target_flags;
enum machine_mode { VOIDmode,
MAX_MACHINE_MODE };

extern const unsigned char mode_size[(int) MAX_MACHINE_MODE];

extern const unsigned short mode_bitsize[(int) MAX_MACHINE_MODE];
void *
simplify_subreg (enum machine_mode outermode)
{
    int offset, part;
    unsigned long val = 0;

    if (((target_flags & (1 << 9)) != 0) || (((target_flags & (1 << 9)) != 0) && ! (target_flags & (1 << 
11))))
    {
        if (((target_flags & (1 << 9)) != 0) != (((target_flags & (1 << 9)) != 0) && ! (target_flags & (1 
<< 11)))
            && (mode_size[(int) (outermode)]) < 4)
            offset = (offset + (8 * 4) - (mode_bitsize[(int) (outermode)])
                      - 2 * (offset % (8 * 4)));
    }
    return (void *) 0;
}
