函数名称：Dynamic initialization: padding may be left uninitialized.

函数原型：static __attribute__((__noinline__)) __attribute__((__section__(".init.text"))) __attribute__((__cold__)) int leaf_small_hole_dynamic_all(unsigned long sp, bool fill, struct test_small_hole *arg)

返回类型：int

参数：

类型参数名称
unsigned longsp
boolfill
struct test_small_hole *arg
269  struct test_small_hole var = {one = one, two = two, 3 byte padding hole here. = 3 byte padding hole here. , 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
269  Location and size tracking to validate fill and test are colocated. 等于var
269  fill_size等于var的长度
269  __builtin_memset(Location and size tracking to validate fill and test are colocated. , (char)((sp & 0xff) | Volatile mask to convince compiler to copy memory with 0xff. ), fill_size)
