From b823fd9ba56d56e3cbb5b05e7a4815fb0914204a Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Tue, 9 Oct 2012 09:28:15 +0000 Subject: ARM: prevent misaligned array inits Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.
