Nadav Rotem 3e883734fa During the CodeGenPrepare we often lower intrinsics (such as objsize) ... and allow some optimizations to turn conditional branches into unconditional. This commit adds a simple control-flow optimization which merges two consecutive basic blocks which are connected by a single edge. This allows the codegen to operate on larger basic blocks. rdar://11973998 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161852 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-14 05:19:07 +00:00
