From 5c5e1ea3cdccc5af0b2d3de15a9c3739c30ec88c Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Fri, 13 Jan 2012 18:56:36 +0000 Subject: [PATCH] ARM: 4-byte align start of all asm functions Due to apprent bugs in the GNU assembler and/or linker, relocations can be incorrectly processed if the alignment of a Thumb instruction is changed in the output file compared to the input object. This fixes crashes in h264 decoding with Thumb enabled. No effect in ARM mode since everything is 4-byte aligned there.
