* [NVPTX] Add more precise PTX/SM target attributesJustin Holewinski2012-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each SM and PTX version is modeled as a subtarget feature/CPU. Additionally, PTX 3.1 is added as the default PTX version to be out-of-the-box compatible with CUDA 5.0. Available CPUs for this target: sm_10 - Select the sm_10 processor. sm_11 - Select the sm_11 processor. sm_12 - Select the sm_12 processor. sm_13 - Select the sm_13 processor. sm_20 - Select the sm_20 processor. sm_21 - Select the sm_21 processor. sm_30 - Select the sm_30 processor. sm_35 - Select the sm_35 processor. Available features for this target: ptx30 - Use PTX version 3.0. ptx31 - Use PTX version 3.1. sm_10 - Target SM 1.0. sm_11 - Target SM 1.1. sm_12 - Target SM 1.2. sm_13 - Target SM 1.3. sm_20 - Target SM 2.0. sm_21 - Target SM 2.1. sm_30 - Target SM 3.0. sm_35 - Target SM 3.5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167699 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert the majority of the next patch in the address space series:Chandler Carruth2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert the series of commits starting with r166578 which introduced theChandler Carruth2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why. Summary of reverted revisions: r166634: Fix a compiler warning with an unused variable. r166607: Add some cleanup to the DataLayout changes requested by Chandler. r166596: Revert "Back out r166591, not sure why this made it through since I cancelled the command.

* Extend TargetPassConfig to allow running only a subset of the normal passes.Bob Wilson2012-07-02
| | | | | | | | | | | | | | | | | This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8
* Add all codegen passes to the PassManager via TargetPassConfig.Bob Wilson2012-07-02

* Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth2012-06-29
| | | | | | | | | | | | | | | | | This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg.

* There are a number of generic inline asm operand modifiers thatJack Carter2012-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | up to r158925 were handled as processor specific. Making them generic and putting tests for these modifiers in the CodeGen/Generic directory caused a number of targets to fail. This commit addresses that problem by having the targets call the generic routine for generic modifiers that they don't currently have explicit code for. For now only generic print operands 'c' and 'n' are supported.vi Affected files: test/CodeGen/Generic/asm-large-immediate.ll lib/Target/PowerPC/PPCAsmPrinter.cpp lib/Target/NVPTX/NVPTXAsmPrinter.cpp lib/Target/ARM/ARMAsmPrinter.cpp lib/Target/XCore/XCoreAsmPrinter.cpp lib/Target/X86/X86AsmPrinter.cpp lib/Target/Hexagon/HexagonAsmPrinter.cpp lib/Target/CellSPU/SPUAsmPrinter.cpp lib/Target/Sparc/SparcAsmPrinter.cpp lib/Target/MBlaze/MBlazeAsmPrinter.cpp lib/Target/Mips/MipsAsmPrinter.cpp MSP430 isn't represented because it did not even run with the long existing 'c' modifier and it was not apparent what needs to be done to get it inline asm ready.
