X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=50eea2bfa79cc6bfef9014c2e0cb89d5a458969f;p=dpdk.git

test: fix build with GCC 11

GCC 11 complains that 'a' is uninitialized.

../dpdk/app/test/test_prefetch.c: In function 'test_prefetch':
../dpdk/app/test/test_prefetch.c:25:9:
error: 'a' may be used uninitialized [-Werror=maybe-uninitialized]
   25 |         rte_prefetch0(&a);
      |         ^~~~~~~~~~~~~~~~~

Fix by initializing 'a'.
