Subject: [PATCH] use _Alignof to avoid UB in ALIGNOF
|
||||
|
||||
WG14 N2350 clearly says that it is an UB having type definitions
|
||||
within "offsetof" [1]. Clang 16+ has started diagnosing it [2].
|
||||
This patch changes the implementation of macro
|
||||
"ALIGNOF" to builtin "_Alignof" to avoid undefined behavior.
|
||||
|
||||
_Alignof() return the ABI required minimum alignment.
