From 67560734daab81c050a13d3b435d7eca4442c199 Mon Sep 17 00:00:00 2001 From: Xavier Simonart Date: Tue, 8 Oct 2019 17:54:22 -0400 Subject: Fix compatibility with GCC 6 and earlier fb0c44a fixed compilation on GCC 8 by using: 1) #pragma GCC diagnostic ignored "-Wstringop-truncation" 2) __attribute__ ((fallthrough)); However, -Wstringop-truncation has only been introduced in GCC 8 and __attribute__ ((fallthrough)) has only been introduced in GCC 7. Hence they caused Warnings/Errors on earlier versions. Comments about fallthough (see https://developers.redhat.com/blog/2017/03/10/wimplicit-fallthrough-in-gcc-7/) can be used on GCC 8 to prevent fall through warnings Signed-off-by: Xavier Simonart Change-Id: I6f22e023191bbf22d8b01f1812061795a6494134 --- VNFs/DPPD-PROX/handle_acl.c | 2 +- VNFs/DPPD-PROX/parse_utils.c | 4 ++-- VNFs/DPPD-PROX/prox_compat.h | 1 + 3 files changed, 4 insertions(+), 3 deletions(-) diff --git a/VNFs/DPPD-PROX/handle_acl.c b/VNFs/DPPD-PROX/handle_acl.c index c0a1b86b..5138eef9 100644 --- a/VNFs/DPPD-PROX/handle_acl.c +++ b/VNFs/DPPD-PROX/handle_acl.c @@ -108,7 +108,7 @@ static int handle_acl_bulk(struct task_base *tbase, struct rte_mbuf **mbufs, uin break; case ACL_ALLOW: out[i] = 0; - __attribute__ ((fallthrough)); + // __attribute__ ((fallthrough)); case ACL_RATE_LIMIT: set_tc(mbufs[i], 3); break; diff --git a/VNFs/DPPD-PROX/parse_utils.c b/VNFs/DPPD-PROX/parse_utils.c index 84ff8cc9..af98ec2b 100644 --- a/VNFs/DPPD-PROX/parse_utils.c +++ b/VNFs/DPPD-PROX/parse_utils.c @@ -923,12 +923,12 @@ int parse_kmg(uint32_t* val, const char *str2) if (*val >> 22) return -2; *val <<= 10; - __attribute__ ((fallthrough)); + // __attribute__ ((fallthrough)); case 'M': if (*val >> 22) return -2; *val <<= 10; - __attribute__ ((fallthrough)); + // __attribute__ ((fallthrough)); case 'K': if (*val >> 22) return -2; diff --git a/VNFs/DPPD-PROX/prox_compat.h b/VNFs/DPPD-PROX/prox_compat.h index 7564f294..e1ead1d3 100644 --- a/VNFs/DPPD-PROX/prox_compat.h +++ b/VNFs/DPPD-PROX/prox_compat.h @@ -133,6 +133,7 @@ static void *prox_rte_table_create(struct prox_rte_table_params *params, int soc static inline char *prox_strncpy(char * dest, const char * src, size_t count) { #pragma GCC diagnostic push +#pragma GCC diagnostic ignored "-Wpragmas" #pragma GCC diagnostic ignored "-Wstringop-truncation" strncpy(dest, src, count); #pragma GCC diagnostic pop -- cgit 1.2.3-korg
