Replace macro __rte_packed with __rte_packed_begin to push existing pack value and set packing to 1-byte and macro __rte_packed_end to restore the pack value prior to the push. Macro __rte_packed_end is deliberately utilized to trigger a MSVC compiler warning if no existing packing has been pushed allowing easy identification of locations where the __rte_packed_begin is missing. Added parenthesis around *pnum in line __ rte_packed_end (*pnum) = (void *)pn; to avoid patch check error below: ERROR:SPACING: need consistent spacing around '*' (ctx:WxV) 34: FILE: examples/common/neon/port_group.h:27: + } __ rte_packed_end *pnum = (void *)pn; With the parenthesis it becomes a warning, still not ideal, but better Running checkpatch.pl: WARNING:SPACING: space prohibited between function name and open parenthesis '(' 34: FILE: examples/common/neon/port_group.h:27: + } __ rte_packed_end (*pnum) = (void *)pn; Signed-off-by: Andre Muezerie --- examples/common/neon/port_group.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/examples/common/neon/port_group.h b/examples/common/neon/port_group.h index 421e2e8613..b8f8be66e8 100644 --- a/examples/common/neon/port_group.h +++ b/examples/common/neon/port_group.h @@ -21,10 +21,10 @@ static inline uint16_t * port_groupx4(uint16_t pn[FWDSTEP + 1], uint16_t *lp, uint16x8_t dp1, uint16x8_t dp2) { - union { + union __rte_packed_begin { uint16_t u16[FWDSTEP + 1]; uint64_t u64; - } __rte_packed *pnum = (void *)pn; + } __rte_packed_end (*pnum) = (void *)pn; uint16x8_t mask = {1, 2, 4, 8, 0, 0, 0, 0}; int32_t v; -- 2.47.0.vfs.0.3
