Manman Ren	1a5ff287fd	TBAA: remove !tbaa from testing cases if not used. This will make it easier to turn on struct-path aware TBAA since the metadata format will change. llvm-svn: 180796	2013-04-30 17:52:57 +00:00
Bill Wendling	bf4b9afbeb	Second attempt at PR12573: Allow the "SplitCriticalEdge" function to split the edge to a landing pad. If the pass is sure that it thinks it knows what it's doing, then it may go ahead and specify that the landing pad can have its critical edge split. The loop unswitch pass is one of these passes. It will split the critical edges of all edges coming from a loop to a landing pad not within the loop. Doing so will retain important loop analysis information, such as loop simplify. llvm-svn: 155817	2012-04-30 10:44:54 +00:00

Second attempt at PR12573:

Allow the "SplitCriticalEdge" function to split the edge to a landing pad. If
the pass is *sure* that it thinks it knows what it's doing, then it may go ahead
and specify that the landing pad can have its critical edge split. The loop
unswitch pass is one of these passes. It will split the critical edges of all
edges coming from a loop to a landing pad not within the loop. Doing so will
retain important loop analysis information, such as loop simplify.
