Dan Gohman 68de98eef3 Generalize ExtendUsesToFormExtLoad to be usable for ANY_EXTEND, ... in addition to ZERO_EXTEND and SIGN_EXTEND. Fix a bug in the way it checked for live-out values, and simplify the way it find users by using SDNode::use_iterator's (relatively) new features. Also, make it slightly more permissive on targets with free truncates. In SelectionDAGBuild, avoid creating ANY_EXTEND nodes that are larger than necessary. If the target's SwitchAmountTy has enough bits, use it. This exposes the truncate to optimization early, enabling more optimizations. llvm-svn: 68670		2009-04-09 03:51:29 +00:00
