When the vdsp processes the Untitled union in the struct, there is a bug, as shown in the following struct:

Struct restart_block {

Long (* fN) (struct restart_block *);

Union {

Struct {

Unsigned long arg0, arg1, arg2, arg3;

};

/* For futex_wait */

Struct {

U32 * uaddr;

U32 val;

U32 flags;

U32 bitset;

U64 time;

} Futex;

/* For nanosleep */

Struct {

Clockid_t index;

Struct timespec _ User * rmtp;

U64 expires;

} Nanosleep;

/* For poll */

Struct {

Struct pollfd _ User * ufds;

Int NFDs;

Int has_timeout;

Unsigned long TV _sec;

Unsigned long TV _nsec;

} Poll;

};

};
