* [LPM] Switch LICM to actively use LCSSA in addition to preserving it.Chandler Carruth2014-02-11
| | | | | | | | | | | | | | | | | | | | | | | Fixes PR18753 and PR18782. This is necessary for LICM to preserve LCSSA correctly and efficiently. There is still some active discussion about whether we should be using LCSSA, but we can't just immediately stop using it and we *need* LICM to preserve it while we are using it. We can restore the old SSAUpdater driven code if and when there is a serious effort to remove the reliance on LCSSA from all of the loop passes. However, this also serves as a great example of why LCSSA is very nice to have. This change significantly simplifies the process of sinking instructions for LICM, and makes it quite a bit less expensive. It wouldn't even be as complex as it is except that I had to start the process of removing the big recursive LCSSA formation hammer in order to switch even this much of the re-forming code to asserting that LCSSA was preserved. I'll fully remove that next just to tidy things up until the LCSSA debate settles one way or the other. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201148 91177308-0d34-0410-b5e6-96231b3b80d8

* [CodeGenPrepare] Undo changes that happened for the profitability check.Quentin Colombet2014-02-11
| | | | | | | | | | | | | | | | | | The addressing mode matcher checks at some point the profitability of folding an instruction into the addressing mode. When the instruction to be folded has several uses, it checks that the instruction can be folded in each use. To do so, it creates a new matcher for each use and check if the instruction is in the list of the matched instructions of this new matcher. The new matchers may promote some instructions and this has to be undone to keep the state of the original matcher consistent. A test case will follow. <rdar://problem/16020230> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201121 91177308-0d34-0410-b5e6-96231b3b80d8

* [LPM] A terribly simple fix to a terribly complex bug: PR18773.Chandler Carruth2014-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The crux of the issue is that LCSSA doesn't preserve stateful alias analyses. Before r200067, LICM didn't cause LCSSA to run in the LTO pass manager, where LICM runs essentially without any of the other loop passes. As a consequence the globalmodref-aa pass run before that loop pass manager was able to survive the loop pass manager and be used by DSE to eliminate stores in the function called from the loop body in Adobe-C++/loop_unroll (and similar patterns in other benchmarks). When LICM was taught to preserve LCSSA it had to require it as well. This caused it to be run in the loop pass manager and because it did not preserve AA, the stateful AA was lost. Most of LLVM's AA isn't stateful and so this didn't manifest in most cases. Also, in most cases LCSSA was already running, and so there was no interesting change. The real kicker is that LCSSA by its definition (injecting PHI nodes only) trivially preserves AA! All we need to do is mark it, and then everything goes back to working as intended. It probably was blocking some other weird cases of stateful AA but the only one I have is a 1000-line IR test case from loop_unroll, so I don't really have a good test case here. Hopefully this fixes the regressions on performance that have been seen since that revision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201104 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Initialize M0 and emit S_WQM_B64 whenever DS instructions are usedTom Stellard2014-02-10
| | | | | | | | | | | DS instructions that access local memory can only uses addresses that are less than or equal to the value of M0. When M0 is uninitialized, then we experience undefined behavior. This patch also changes the behavior to emit S_WQM_B64 on pixel shaders no matter what kind of DS instruction is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201097 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: use LLVM IR to represent the vshrn operationTim Northover2014-02-10
| | | | | | | | | | vshrn is just the combination of a right shift and a truncate (and the limits on the immediate value actually mean the signedness of the shift doesn't matter).
