enforce experimental tag at beginning of declarations
Putting a '__attribute__((deprecated))' in the middle of a function prototype does not result in the expected result with gcc (while clang is fine with this syntax). $ cat deprecated.c void * __attribute__((deprecated)) incorrect() { return 0; } __attribute__((deprecated)) void *correct(void) { return 0; } int main(int argc, char *argv[]) { incorrect(); correct(); return 0; } $ gcc -o deprecated.o -c deprecated.c deprecated.c: In function ‘main’: deprecated.c:3:1: warning: ‘correct’ is deprecated (declared at deprecated.c:2) [-Wdeprecated-declarations] int main(int argc, char *argv[]) { incorrect(); correct(); return 0; } ^ Move the tag on a separate line and make it the first thing of function prototypes. This is not perfect but we will trust reviewers to catch the other not so easy to detect patterns. sed -i \ -e '/^\([^#].*\)\?__rte_experimental */{' \ -e 's//\1/; s/ *$//; i\' \ -e __rte_experimental \ -e '/^$/d}' \ $(git grep -l __rte_experimental -- '*.h') Special mention for rte_mbuf_data_addr_default(): There is either a bug or a (not yet understood) issue with gcc. gcc won't drop this inline when unused and rte_mbuf_data_addr_default() calls rte_mbuf_buf_addr() which itself is experimental. This results in a build warning when not accepting experimental apis from sources just including rte_mbuf.h. For this specific case, we hide the call to rte_mbuf_buf_addr() under the ALLOW_EXPERIMENTAL_API flag. Signed-off-by: Adrien Mazarguil <> Signed-off-by: David Marchand <>
