Name:memory_is_poisoned

Proto:static __always_inline bool memory_is_poisoned(unsigned long addr, size_t size)

Type:bool

Parameter:

TypeParameterName
unsigned longaddr
size_tsize
151  If __builtin_constant_p(size) Then
153  Case size == 1
154  Return 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  Case size == 2
156  Case size == 4
157  Case size == 8
158  Return memory_is_poisoned_2_4_8(addr, size)
159  Case size == 16
160  Return memory_is_poisoned_16(addr)
161  Default
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  Return memory_is_poisoned_n(addr, size)
