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

| | | | | | | | | | | | | | other passes, such as LoopRotate may invalidate its AliasSet because SSAUpdater does not update the AliasSet properly. This patch teaches SSAUpdater to notify AliasSet that it made changes.

* ARM: Move Thumb2 tests to Thumb2 test file and fix CHECK lines.Jim Grosbach2012-08-13
| | | | | | These tests weren't actually being run before (missing ':' after CHECK). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161800 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the TII::scheduleTwoAddrSource() hook.Jakob Stoklund Olesen2012-08-13
| | | | | | | | | | | | | | | It never does anything when running 'make check', and it get's in the way of updating live intervals in 2-addr. The hook was originally added to help form IT blocks in Thumb2 code before register allocation, but the pass ordering has changed since then, and we run if-conversion after register allocation now. When the MI scheduler is enabled, there will be no less than two schedulers between 2-addr and Thumb2ITBlockPass, so this hook is unlikely to help anything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161794 91177308-0d34-0410-b5e6-96231b3b80d8
