Subject: [dpdk-dev] [PATCH] net/cxgbe: fix build with clang 3.4.2
Date: Wed, 18 Mar 2020 12:52:36 +0000 [thread overview]
Message-ID: <20200318125236.652514-1-ferruh.yigit@intel.com> (raw)
Build error:
.../drivers/net/cxgbe/cxgbe_flow.c:315:2:
error: implicit truncation from 'int' to bitfield changes value
from -1 to 7 [-Werror,-Wbitfield-constant-conversion]
CXGBE_FILL_FS(adap->pf, ~0, pf);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../drivers/net/cxgbe/cxgbe_flow.c:25:2:
note: expanded from macro 'CXGBE_FILL_FS'
__CXGBE_FILL_FS(v, m, fs, elem, e)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../drivers/net/cxgbe/cxgbe_flow.c:15:18: note:
expanded from macro '__CXGBE_FILL_FS'
(fs)->mask.elem = (__m); \
^ ~~~~~
Commit in fixes line changes 'PF_BITWIDTH' to '3', which makes 'fs->pf'
bitfield size '3', changing '~0' to '0x7' to prevent truncation in
assignment.
Fixes: dcd456abe46f ("net/cxgbe: support flow API for matching all packets on PF")
