From 9f8491ecbfb80696b62a5a878fe40f81a8a0d35c Mon Sep 17 00:00:00 2001 From: Chun-Chen Hsu Date: Tue, 13 Mar 2018 18:24:21 +0800 Subject: arm: Fix maybe-uninitialized GCC warnings GCC 7 generates maybe-uninitialized warnings at the code that updates the "dest" variables in the writeVecElem function of neon64_mem.hh file. It is because the generated code does not appropriately initialize the output variable before passing it to the writeVecElem function. This patch initializes the output variable to fix this.
