Manman Ren	f3fedb6935	JumpThreading: when default destination is the destination of some cases in a switch, make sure we include the value for the cases when calculating edge value from switch to the default destination. rdar://12241132 llvm-svn: 163270	2012-09-05 23:45:58 +00:00
Frits van Bommel	3d1803495e	Teach jump threading to "look through" a select when the branch direction of a terminator depends on it. When it sees a promising select it now tries to figure out whether the condition of the select is known in any of the predecessors and if so it maps the operands appropriately. llvm-svn: 121859	2010-12-15 09:51:20 +00:00
