* Fix inserting instructions before last in bundle.Matt Arsenault2013-08-262-17/+21
| | | | | | | | | | | The builder inserts from before the insert point, not after, so this would insert before the last instruction in the bundle instead of after it. I'm not sure if this can actually be a problem with any of the current insertions. llvm-svn: 189285
* Debug Info: add an identifier field to DICompositeType.Manman Ren2013-08-26182-482/+511
| | | | | | | | | | | | | | | | | | DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString. Update testing cases to include an extra field for DICompositeType. The identifier field will be used by type uniquing so a front end can genearte a DICompositeType with a unique identifer. llvm-svn: 189282
* LoopVectorize: Implement partial loop unrolling when vectorization is not ↵Nadav Rotem2013-08-262-167/+534
| | | | | | | | | | | | | | | | profitable. This patch enables unrolling of loops when vectorization is legal but not profitable. We add a new class InnerLoopUnroller, that extends InnerLoopVectorizer and replaces some of the vector-specific logic with scalars. This patch does not introduce any runtime regressions and improves the following workloads: SingleSource/Benchmarks/Shootout/matrix -22.64% SingleSource/Benchmarks/Shootout-C++/matrix -13.06% External/SPEC/CINT2006/464_h264ref/464_h264ref -3.99% SingleSource/Benchmarks/Adobe-C++/simple_types_constant_folding -1.95% llvm-svn: 189281

* ARM: Enable machine verifier for a few more tests.Jim Grosbach2013-08-262-3/+3
| | | | | | | | | Now that fast-isel is in better shape, we can enable the machine verifier for these tests, too. rdar://12594152 llvm-svn: 189275
* ARM: Constrain regclass for TSTri instruction.Jim Grosbach2013-08-262-1/+3
| | | | | | | | | Get the register class right for the TST instruction. This keeps the machine verifier happy, enabling us to turn it on for another test. rdar://12594152 llvm-svn: 189274

* ARM: FastISel verifier error cleanup.Jim Grosbach2013-08-262-1/+8
| | | | | | | | | Constant pool and global value reference instructions need more restricted register classes than plain GPR. rdar://12594152 llvm-svn: 189270
* ARM: Fix ELF global base reg intialization.Jim Grosbach2013-08-261-3/+8
| | | | | | | | | | | | | | | | | | The create machine code wasn't properly in SSA, which the machine verifier properly complains about. Now that fast-isel is closer to verifier clean, errors like this show up more clearly. Additionally, the Thumb pseudo tPICADD was used for both ARM and Thumb mode functions, which is obviously wrong. Fix that along the way. Test case is part of the following commit which will finish making an additional fast-isel test verifier clean an enable it for the regression test suite. This commit is separate since its not just a verifier cleanup, but an actual correctness issue. rdar://12594152 (for the fast-isel verifier aspects) llvm-svn: 189269
* [PowerPC] More fast-isel chunks (returns and integer extends)Bill Schmidt2013-08-265-3/+472
| | | | | | | | | | | | | | | | | Incremental improvement to fast-isel for PPC64. This allows us to select on ret, sext, and zext. Filling in sext/zext improves some of the existing logic in handling compare-immediates that needed extends. A simplified return convention for fast-isel is also added to the PPC64 calling conventions. All call/return processing for DAG selection is handled with custom code, so there isn't an existing CC to rely on here. The include of PPCGenCallingConv.inc causes compiler warnings due to the 32-bit calling conventions that are not used, so the dummy function "usePPC32CCs()" is added here to silence those. Test cases for the return and extend logic are added. llvm-svn: 189266

* SelectionDAG: Remove unnecessary uses of TargetLowering::getPointerTy()Tom Stellard2013-08-268-43/+190
| | | | | | | | | | | | If we have a binary operation like ISD:ADD, we can set the result type equal to the result type of one of its operands rather than using TargetLowering::getPointerTy(). Also, any use of DAG.getIntPtrConstant(C) as an operand for a binary operation can be replaced with: DAG.getConstant(C, OtherOperand.getValueType()); llvm-svn: 189227

* SelectionDAG: Use correct pointer size when lowering function arguments v2Tom Stellard2013-08-268-14/+79
| | | | | | | | | | | | | | | | This adds minimal support to the SelectionDAG for handling address spaces with different pointer sizes. The SelectionDAG should now correctly lower pointer function arguments to the correct size as well as generate the correct code when lowering getelementptr. This patch also updates the R600 DataLayout to use 32-bit pointers for the local address space. v2: - Add more helper functions to TargetLoweringBase - Use CHECK-LABEL for tests llvm-svn: 189221
* CMake Xcode builds: symlink tblgen targets out to bin/.Douglas Gregor2013-08-261-0/+10
| | | | | | | | | | | Xcode always puts executable targets in the directory bin/<Config>. When building separate LLVM and Clang projects for Xcode, this prevents the CMake-configured project for Clang from finding llvm-tblgen. Add a symlink so that tblgen executables are always available in bin/ (regardless of the configuration LLVM is built with). llvm-svn: 189220

PPCFastISel::PPCEmitIntExt() is just roughed in and will be expanded in a future patch. This also corrects a problem with selection for constant pool entries in JIT mode or with small code model. llvm-svn: 189202

So 'mov word ptr [5], al' is no longer accepted. -x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size. -Intel syntax printing prints the ptr size and places brackets around the address immediate. Known remaining issues with these instructions: -Segment override prefix is not supported. PR16962 and PR16961. -Immediate size should be changed by address size prefix. llvm-svn: 189201

| | | | | | | | | We currently emit labels with the prefix Lllvm$workaround$fake$stub$ if the target's MCAsmInfo has getLinkOnceDirective() mapped to something interesting. This was apparently a work around introduced in r31033 for binutils that we don't need anymore. llvm-svn: 189187
* Start to add the LLVM builtins to the mips16 exclusion lists for fp.Reed Kotler2013-08-252-1/+29
| | | | | | | | | | | | | I need to add the rest of these to the list or else to delay putting out the actual stub until later in code generation when I know if the external function ever got emitted Resubmit this patch. The target triple needs to be added to the test so that clang does not tell the backend the wrong target when the host is BSD. There is a clang bug in here somewhere that I need to track down. At Mips this has been filed internally as a bug. llvm-svn: 189186
