            Bug ID: 1644
           Summary: DPDK may not build on some Intel CPUs using clang <
                    3.7.0
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: meson
          Assignee: dev@dpdk.org
          Reporter: nandinipersad361@gmail.com
  Target Milestone: ---

When compiling DPDK with an earlier version than 3.7.0 of clang, CPU flags are
not detected on some Intel platforms such as Intel Broadwell/Skylake (and
possibly future CPUs), and therefore compilation fails due to missing
intrinsics.

Implication:
DPDK will not build when using a clang version < 3.7.0.

Resolution/Workaround:
Use clang 3.7.0 or higher, or gcc.

Affected Environment/Platform:
Platforms with Intel Broadwell/Skylake using an old clang version.

Driver/Module:
Environment Abstraction Layer (EAL).

--- Comment #1 from Stephen Hemminger (stephen@networkplumber.org) ---
You are living in the past. Clang 3.7.0 was released over 10 years ago.
DPDK doesn't need to worry about this.
