2012-08-13LICM uses AliasSet information to hoist and sink instructions. However, ↵Nadav Rotem
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. The testcase in PR12901 is too big to be useful and I could not reduce it to a normal size. rdar://11872059 PR12901 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161803 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-13MemoryDependenceAnalysis attempts to find the first memory dependency for ↵Nadav Rotem
function calls. Currently, if GetLocation reports that it did not find a valid pointer (this is the case for volatile load/stores), we ignore the result. This patch adds code to handle the cases where we did not obtain a valid pointer. rdar://11872864 PR12899 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161802 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-13ARM: Move Thumb2 tests to Thumb2 test file and fix CHECK lines.Jim Grosbach
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
2012-08-13Remove the TII::scheduleTwoAddrSource() hook.Jakob Stoklund Olesen
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

Detect when there is not enough available ILP, so if-conversion can't speculate instructions for free.

Trace::getResourceLength() computes the number of cycles required to execute the trace when ignoring data dependencies. The number can be compared to the critical path to estimate the trace ILP.
