Though it is probably worth backporting if it is a problem with gcc 9.x.
WDYT?
I can add a Cc: sta...@dpdk.org when applying.
Agree, should be backported.

The rte_altivec.h is related to another open patch required to build on
POWER systems (http://patches.dpdk.org/patch/69605/) that's waiting to
be accepted. You may not have encountered it if you're not building the
MLX5 PMD which has additional library requirements.
Is there a point in havin

Building DPDK on Ubuntu 20.04 with GCC 9.3.0 results in a "subscript is
outside array bounds" message in rte_memcpy function. The build error
is caused by an interaction between __builtin_constant_p and
"-Werror=array-bounds" as described in this bugzilla:
