2013-04-30InstCombine: Fold more shuffles of shuffles.Jim Grosbach
Always fold a shuffle-of-shuffle into a single shuffle when there's only one input vector in the first place. Continue to be more conservative when there's multiple inputs. rdar://13402653 PR15866 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180802 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-30LocalStackSlotAllocation improvementsHal Finkel
First, taking advantage of the fact that the virtual base registers are allocated in order of the local frame offsets, remove the quadratic register-searching behavior. Because of the ordering, we only need to check the last virtual base register created. Second, store the frame index in the FrameRef structure, and get the frame index and the local offset from this structure at the top of the loop iteration. This allows us to de-nest the loops in insertFrameReferenceRegisters (and I think makes the code cleaner). I also moved the needsFrameBaseReg check into the first loop over instructions so that we don't bother pushing FrameRefs for instructions that don't want a virtual base register anyway. Lastly, and this is the only functionality change, avoid the creation of single-use virtual base registers. These are currently not useful because, in general, they end up replacing what would be one r+r instruction with an add and a r+i instruction. Committing this removes the XFAIL in CodeGen/PowerPC/2007-09-07-LoadStoreIdxForms.ll Jim has okayed this off-list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180799 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-30Change getSlotIndex to return unsigned.Rafael Espindola
The actual storage was already using unsigned, but the interface was using uint64_t. This is wasteful on 32 bits and looks to be the root causes of a miscompilation on Windows where a value was being sign extended to 64bits to compare with the result of getSlotIndex.

This fixes the optimization introduced in r179748 and reverted in r179750. While the optimization was sound, it did not properly respect differences in bit-width. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180777 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-30Refactoring patch.Stepan Dyatkovskiy
1. VarArgStyleRegisters: functionality that emits "store" instructions for byval regs moved out into separated method "StoreByValRegs". Before this patch VarArgStyleRegisters had confused use-cases. It was used for both variadic functions and for regular functions with byval parameters. In last case it created new stack-frame and registered it as VarArg frame, that is wrong. This patch replaces VarArgsStyleRegisters usage for byval parameters with StoreByValRegs method. 2. In ARMMachineFunctionInfo, "get/setVarArgsRegSaveSize" was renamed to "get/setArgRegsSaveSize". By the same reason. Sometimes it was used for variadic functions, and sometimes for byval parameters in regular functions. Actually, this property means the size of registers, that keeps arguments, and thats why it was renamed. 3. In ARMISelLowering.cpp, ARMTargetLowering class, in methods computeRegArea and StoreByValRegs, VARegXXXXXX was renamed to ArgRegsXXXXXX still by the same reasons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180774 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29Emit the TLS initialization function pointers into the correct section.Bill Wendling
The `llvm.tls_init_funcs' (created by the front-end) holds pointers to the TLS initialization functions. These need to be placed into the correct section so that they are run before `main()'. <rdar://problem/13733006> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180737 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-29Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola
For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29SimplifyCFG: If convert single conditional storesArnold Schwaighofer
This resurrects r179957, but adds code that makes sure we don't touch atomic/volatile stores: This transformation will transform a conditional store with a preceeding uncondtional store to the same location: a[i] = may-alias with a[i] load if (cond) a[i] = Y into an unconditional store. a[i] = X may-alias with a[i] load tmp = cond ? Y : X; a[i] = tmp We assume that on average the cost of a mispredicted branch is going to be higher than the cost of a second store to the same location, and that the secondary benefits of creating a bigger basic block for other optimizations to work on outway the potential case where the branch would be correctly predicted and the cost of the executing the second store would be noticably reflected in performance. hmmer's execution time improves by 30% on an imac12,2 on ref data sets. With this change we are on par with gcc's performance (gcc also performs this transformation). There was a 1.2 % performance improvement on a ARM swift chip. Other tests in the test-suite+external seem to be mostly uninfluenced in my experiments: This optimization was triggered on 41 tests such that the executable was different before/after the patch. Only 1 out of the 40 tests (dealII) was reproducable below 100% (by about .4%). Given that hmmer benefits so much I believe this to be a fair trade off. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180731 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29Replace ObjRelocationInfo with relocation_iterator.Rafael Espindola
For MachO we need information that is not represented in ObjRelocationInfo. Instead of copying the bits we think are needed from a relocation_iterator, just pass the relocation_iterator down to the format specific functions. No functionality change yet as we still drop the information once processRelocationRef returns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180711 91177308-0d34-0410-b5e6-96231b3b80d8
