false positives with branch prediction

[Paul Aitken]

How can I avoid false positive reports when using DPDK's "likely" and "unlikely" branch prediction macros?

eg, "Memory leak" is reported for this snippet:

    ptr = calloc(...);
    if (unlikely(!ptr)) {
        RTE_LOG(...);
        return NULL;
    }

Thanks.

you could test the configuration in gnu.cfg

  <define name="likely(X)" value="(X)"/>
  <define name="unlikely(X)" value="(X)"/>

Thanks @danielmarjamaki, cppcheck --library=gnu ... solved that.
