> Subject: [PATCH v2] eal: add nonnull and access function attributes
>
> Add "nonnull" function attribute to help the compiler detect a NULL pointer being passed
> to a function not accepting NULL pointers as an argument at build time.
>
> Add "access" function attribute to tell the compiler how a function accesses its pointer
> arguments.
>
> Add these attributes to the rte_memcpy() function, as the first in hopefully many to come.
>
> v2:
> * Only define "nonnull" for GCC and CLANG.
> * Append _param/_params to prepare for possible future attributes
> attached directly to the individual parameters, like __rte_unused.
> * Use RTE_TOOLCHAIN_GCC instead of RTE_CC_GCC, to fix complaints about
> GCC_VERSION being undefined.
> * Try to fix Doxygen compliants.
