Chris Lattner 421fa9e32e Teach jump threading some more simple tricks: ... 1) have it fold "br undef", which does occur with surprising frequency as jump threading iterates. 2) teach j-t to delete dead blocks. This removes the successor edges, reducing the in-edges of other blocks, allowing recursive simplification. 3) Fold things like: br COND, BBX, BBY BBX: br COND, BBZ, BBW which also happens because jump threading iterates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60470 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-03 07:48:08 +00:00
