From 79fa5c2a9992f5fdef2cd7cb4e76704940699fbc Mon Sep 17 00:00:00 2001 From: Jan Viktorin Date: Tue, 3 Nov 2015 00:47:26 +0100 Subject: [PATCH] mk: ignore alignment errors for ARMv7 There several issues with alignment when compiling for ARMv7. They are not considered to be fatal (ARMv7 supports unaligned access of 32b words), so we just leave them as warnings. They should be solved later, however.
