Dan Gohman a4b28ca3c9 Don't split critical edges during the AddUsersIfInteresting phase ... of LSR. This makes the AddUsersIfInteresting phase of LSR a pure analysis instead of a phase that potentially does CFG modifications. The conditions where this code would actually perform a split are rare, and in the cases where it actually would do a split the split is usually undone by CodeGenPrepare, and in cases where splits actually survive into codegen, they appear to hurt more often than they help. llvm-svn: 70625		2009-05-02 05:36:01 +00:00
