[Bug middle-end/35304] New: Missing store sinking (code size optimization) at tree level

[xinliangli at gmail dot com]

int* g;

void foo(int m)
{
     if (m)
       *g  = 1;
     else
       *g = 2;
}

should be (at least with -Os)

void foo(int m)
{
    if (m)
     t = 1;
    else
     t = 2;
    *g = t;
}
