Subject: [dpdk-dev] [PATCH] event/cnxk: fix clang warning on Arm
Date: Thu, 10 Jun 2021 07:25:10 +0000 [thread overview]
Message-ID: <20210610072511.232027-1-ruifeng.wang@arm.com> (raw)
Build with Clang-10 has warning:
drivers/event/cnxk/cnxk_tim_worker.h:372:23: warning: value size does not match register size specified by the constraint and modifier [-Wasm-operand-widths]
: [rem] "=&r"(rem)
^
drivers/event/cnxk/cnxk_tim_worker.h:365:17: note: use constraint modifier "w"
" ldxr %[rem], [%[crem]] \n"
^~~~~~
%w[rem]
Changed variable type to match register size, which placates clang.
Fixes: 300b796262a1 ("event/cnxk: add timer arm routine")
