Nadav Rotem	9f567c62f2	The code pattern "imm0_255_neg" is used for checking if an immediate value is a small negative number. This patch changes the definition of negative from -0..-255 to -1..-255. I am changing this because of a bug that we had in some of the patterns that assumed that "subs" of zero does not set the carry flag. rdar://12028498 llvm-svn: 167963	2012-11-14 19:39:15 +00:00
