Clang Static Analyzer is a source code analysis tool to find bugs. This patch adds make target to trigger static analysis using below commands.
./boot.sh For Clang: ./configure CC=clang --with-dpdk For GCC: ./configure CC=gcc --with-dpdk CFLAGS="-std=gnu99" make clang-analyze scan-view --host=<ip address> --port <PORT> $OVS_DIR>/clang-analyzer-results/yyyy-mm-dd-114251-1027-1> --allow-all-hosts Results can be viewed on browser: http://<ip address>:<PORT>/ v2->v3: * Refactor the code as suggested. * Add --use-cc to scan-build. v1->v2: * Change the output directory to tests/clang-analyzer-results * Remove '-j' make option, This might potentially hang some system while spawning infinite jobs.
