> The '-Wno-shift-negative-value' option only got introduced after 3.6.0 clang release.  Pls. let us know if we need to support a minimum version of clang. We had asked this question earlier in the dpdk community, however we didn't hear back from anyone so far.

I use clang-3.6.2.
You are right there is no official requirement in
doc/guides/linux_gsg/sys_reqs.rst.
Opinions about minimal version to support?
