Owen Anderson aefeb448a9 Add an InstCombine transform to recognize instances of manual overflow-safe addition ... (performing the addition in a wider type and explicitly checking for overflow), and fold them down to intrinsics. This currently only supports signed-addition, but could be generalized if someone works out the magic constant formulas for other operations. Fixes <rdar://problem/8558713>. llvm-svn: 121905		2010-12-15 22:32:38 +00:00
