返回类型：int

参数：

类型参数名称
unsigned longsp
boolfill
struct test_trailing_hole *arg
269  struct test_trailing_hole var = {one = one, two = two, three = three, four = four, }
269  Location and size tracking to validate fill and test are colocated. 等于var
269  target_size等于var的长度
269  __builtin_memset(buf, (char)(sp & 0xff), buf的长度)
269  如果fill则
