[dpdk-dev] [PATCH 0/6] fix build warnings and errors in SUSE11 SP3

[Yong Liu]

From: Marvin Liu <yong.liu@intel.com>

SUSE11 SP3 default gcc version is 4.3.4. Some options not supported in this
version. This patch set add gcc version check for those options and fix other
build warning in Suse11 SP3.

Marvin Liu (6):
  fix sse3 functions not found with gcc 4.3.4
  fix fm10k driver build error when gcc version elder than 4.4
  fix build error when initialized structure in enic driver
  fix build error in app/test with gcc4.3
  fix build error in app/test with gcc4.3
  fix build error for implicit declaration of function pread

[dpdk-dev] [PATCH] app/test-pmd: fix incorrect port number check

[Yong Liu]

testpmd parameter "nb-port" mean the number of forwarding port.
It's incorrect to use function port_id_is_invalid to check number of ports.

[dpdk-dev] [PATCH 1/6] fix sse3 functions not found with gcc 4.3.4

[Yong Liu]

From: Marvin Liu <yong.liu@intel.com>

Build dpdk2.0 in Suse11 SP3, there'll be errors for not found sse3 functions.
rte_memcpy.h: In function ‘rte_memcpy’:
rte_memcpy.h:625: error: implicit declaration of function ‘_mm_alignr_epi8’
rte_memcpy.h:625: error: nested extern declaration of ‘_mm_alignr_epi8’
rte_memcpy.h:625: error: incompatible type for argument 2 of ‘_mm_storeu_si128’

These functions defined in tmmintrin.h and should be included in.

[dpdk-dev] [PATCH 2/6] fix fm10k driver build error when gcc version elder than 4.4

[Yong Liu]

From: Marvin Liu <yong.liu@intel.com>

Build fm10k driver in Suse11 SP3 will be failed for unrecognized flag.
cc1: error: unrecognized command line option "-Wno-unused-but-set-variable"

This flag is supported from gcc 4.4, so add gcc version check in fm10k.
In the same time, make option check more clear in ixgbe driver.

[dpdk-dev] [PATCH 3/6] fix build error when initialized structure in enic driver

[Yong Liu]

From: Marvin Liu <yong.liu@intel.com>

gcc4.3 will raise warnings in blow code for initialized field overwritten.

enic_main.c: In function ‘enic_set_rsskey’:
enic_main.c:845: error: initialized field overwritten
enic_main.c:845: error: (near initialization for ‘rss_key.key’)
enic_main.c:846: error: initialized field overwritten
enic_main.c:846: error: (near initialization for ‘rss_key.key’)
enic_main.c:847: error: initialized field overwritten
enic_main.c:847: error: (near initialization for ‘rss_key.key’)

static union vnic_rss_key rss_key = {
	.key[0] = ...,
	.key[1] = ...,
	.key[2] = ...,
	.key[3] = ...,
};

Change struct initialized code reference to ISO 9899 section 6.7.8.
gcc4.3 will happy for that.

static union vnic_rss_key rss_key = {
	.key = {
		[0] = ...,
		[1] = ...,
		[2] = ...,
		[3] = ...,
