Subject: app/test: fix build constructor with gcc < 4.4
X-Git-Tag: spdx-start~9394
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d788ccb1309069286fc2e3ca0355a2a480b65986;p=dpdk.git

app/test: fix build constructor with gcc < 4.4

Build app/test will be failed for function only defined but not used.
test_prefetch.c:65: error: ‘testfn_prefetch_cmd’ defined but not used

Add attribute used in test function declaration can fix this.
static void __attribute__((used)) testfn_##t(void);

Fixes: 727909c59231 ("app/test: introduce dynamic commands list")
