函数名称：memory_is_poisoned

函数原型：static __always_inline bool memory_is_poisoned(unsigned long addr, size_t size)

返回类型：bool

参数：

类型参数名称
unsigned longaddr
size_tsize
151  如果__builtin_constant_p(size)则
153  当:size恒等于1
154  返回:All functions below always inlined so compiler could* perform better optimizations in each of __asan_loadX/__assn_storeX* depending on memory access size X.
155  当:size恒等于2
156  当:size恒等于4
157  当:size恒等于8
158  返回:memory_is_poisoned_2_4_8(addr, size)
159  当:size恒等于16
160  返回:memory_is_poisoned_16(addr)
161  默认
162  BUILD_BUG - break compile if used.* If you have some code that you expect the compiler to eliminate at* build time, you should use BUILD_BUG to detect if it is* unexpectedly used.()
166  返回:memory_is_poisoned_n(addr, size)
