From 684f970e2fd2dc0eb8292500903f54f1ebda0e75 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 17 Apr 2005 15:51:02 +0100 Subject: [PATCH] ARM: bitops Convert ARM bitop assembly to a macro. All bitops follow the same format, so it's silly duplicating the code when only one or two instructions are different.
