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

函数原型：static __attribute__((__noinline__)) __attribute__((__section__(".init.text"))) __attribute__((__cold__)) int leaf_small_hole_static_partial(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
265  struct test_small_hole var = {two = 0, }
265  Location and size tracking to validate fill and test are colocated. 等于var
265  target_size等于var的长度
265  __builtin_memset(buf, (char)(sp & 0xff), buf的长度)
265  如果fill则
265  Location and size tracking to validate fill and test are colocated. 等于var
265  fill_size等于var的长度
265  __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)
265  Static initialization: padding may be left uninitialized.
