2013-01-10Stack Alignment: throw error if we can't satisfy the minimal alignmentManman Ren
requirement when creating stack objects in MachineFrameInfo. Add CreateStackObjectWithMinAlign to throw error when the minimal alignment can't be achieved and to clamp the alignment when the preferred alignment can't be achieved. Same is true for CreateVariableSizedObject. Will not emit error in CreateSpillStackObject or CreateStackObject. As long as callers of CreateStackObject do not assume the object will be aligned at the requested alignment, we should not have miscompile since later optimizations which look at the object's alignment will have the correct information. rdar://12713765 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172027 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-08Pad Short Functions for Intel AtomPreston Gurd
The current Intel Atom microarchitecture has a feature whereby when a function returns early then it is slightly faster to execute a sequence of NOP instructions to wait until the return address is ready, as opposed to simply stalling on the ret instruction until the return address is ready. When compiling for X86 Atom only, this patch will run a pass, called "X86PadShortFunction" which will add NOP instructions where less than four cycles elapse between function entry and return. It includes tests. This patch has been updated to address Nadav's review comments - Optimize only at >= O1 and don't do optimization if -Os is set - Stores MachineBasicBlock* instead of BBNum - Uses DenseMap instead of std::map - Fixes placement of braces Patch by Andy Zhang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171879 91177308-0d34-0410-b5e6-96231b3b80d8

turning a code like this: if (foo) free(foo) into that: free(foo) Move a call to free from basic block FB into FB's predecessor, P, when the path from P to FB is taken only if the argument of free is not equal to NULL. Some restrictions apply on P and FB to be sure that this code motion is profitable. Namely: 1. FB must have only one predecessor P. 2. FB must contain only the call to free plus an unconditional branch to S. 3. P's successors are FB and S. Because of 1., we will not increase the code size when moving the call to free from FB to P. Because of 2., FB will be empty after the move. Because of 2. and 3., P's branch instruction becomes useless, so as FB (simplifycfg will do the job). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171762 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Switch the SCEV expander and LoopStrengthReduce to useChandler Carruth
TargetTransformInfo rather than TargetLowering, removing one of the primary instances of the layering violation of Transforms depending directly on Target. This is a really big deal because LSR used to be a "special" pass that could only be tested fully using llc and by looking at the full output of it. It also couldn't run with any other loop passes because it had to be created by the backend. No longer is this true. LSR is now just a normal pass and we should probably lift the creation of LSR out of lib/CodeGen/Passes.cpp and into the PassManagerBuilder. =] I've not done this, or updated all of the tests to use opt and a triple, because I suspect someone more familiar with LSR would do a better job. This change should be essentially without functional impact for normal compilations, and only change behvaior of targetless compilations. The conversion required changing all of the LSR code to refer to the TTI interfaces, which fortunately are very similar to TargetLowering's interfaces. However, it also allowed us to *always* expect to have some implementation around. I've pushed that simplification through the pass, and leveraged it to simplify code somewhat. It required some test updates for one of two things: either we used to skip some checks altogether but now we get the default "no" answer for them, or we used to have no information about the target and now we do have some. I've also started the process of removing AddrMode, as the TTI interface doesn't use it any longer. In some cases this simplifies code, and in others it adds some complexity, but I think it's not a bad tradeoff even there. Subsequent patches will try to clean this up even further and use other (more appropriate) abstractions. Yet again, almost all of the formatting changes brought to you by clang-format. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171735 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Switch BBVectorize to directly depend on having a TTI analysis.Chandler Carruth
This could be simplified further, but Hal has a specific feature for ignoring TTI, and so I preserved that. Also, I needed to use it because a number of tests fail when switching from a null TTI to the NoTTI nonce implementation. That seems suspicious to me and so may be something that you need to look into Hal. I worked it by preserving the old behavior for these tests with the flag that ignores all target info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171722 91177308-0d34-0410-b5e6-96231b3b80d8
