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. Signed-off-by: Albert ARIBAUD [trini: Switch to usign call cc-option for -mno-unaligned-access as Albert had done previously as that's really correct] Signed-off-by: Tom Rini --- fs/fat/Makefile | 2 ++ 1 file changed, 2 insertions(+) (limited to 'fs/fat/Makefile') diff --git a/fs/fat/Makefile b/fs/fat/Makefile index 9635d36fcf..02e6881670 100644 --- a/fs/fat/Makefile +++ b/fs/fat/Makefile @@ -39,6 +39,8 @@ all: $(LIB) $(AOBJS) $(LIB): $(obj).depend $(OBJS) $(call cmd_link_o_target, $(OBJS)) +# SEE README.arm-unaligned-accesses +$(obj)file.o: CFLAGS += $(PLATFORM_NO_UNALIGNED) ######################################################################### -- cgit v1.2.1
