Use of this tag will cause any caller of the function (that isn't removed by dead code elimination) to emit a warning that the user is making use of an API whos stabilty isn't guaranteed. It also places the function in the .text.experimental section, which is used to validate the tag against the corresponding library version map Signed-off-by: Neil Horman CC: Thomas Monjalon CC: "Mcnamara, John" CC: Bruce Richardson --- lib/librte_compat/rte_compat.h | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/lib/librte_compat/rte_compat.h b/lib/librte_compat/rte_compat.h index 41e8032ba..450dd542c 100644 --- a/lib/librte_compat/rte_compat.h +++ b/lib/librte_compat/rte_compat.h @@ -101,5 +101,16 @@ */ #endif +#ifndef ALLOW_EXPERIMENTAL_APIS +#define __experimental \ +__attribute__((deprecated("Symbol is not yet part of stable abi"), \ +section(".text.experimental"))) + +#else + +#define __experimental \ +__attribute__((section(".text.experimental"))) + +#endif #endif /* _RTE_COMPAT_H_ */ -- 2.14.3
