This creates problems: 1. The InsertPoint used for CodeGenIP does not need to be the end of a block. If it is not, a naive callback will insert a branch instruction into the middle of the block. 2. The BasicBlock the CodeGenIP is pointing to may or may not have a terminator. There is an conflict where to branch to if the block already has a terminator. 3. Some API functions work only with block having a terminator. Some workarounds have been used to insert a temporary terminator that is removed again. 4. Some callbacks are sensitive to whether the BasicBlock has a terminator or not. This creates a callback ordering problem where different callback may have different behaviour depending on whether a previous callback created a terminator or not. The problem also exists for FinalizeCallbackTy where some callbacks do create branch to another "continue" block, but unlike BodyGenCallbackTy does not receive the target as argument. This is not addressed in this patch.With this patch, the callback receives an CodeGenIP into a BasicBlock where to insert instructions. If it has to insert control flow, it can split the block at that position as needed but otherwise no separate ContinuationBB is needed. In particular, a callback can be empty without breaking the emitted IR. If the caller needs the control flow to branch to a specific target, it can insert the branch instruction itself and pass an InsertPoint before the terminator to the callback.Certain frontends such as Clang may expect the current IRBuilder position to be at the end of a basic block. In this case its callbacks must split the block at CodeGenIP before setting the IRBuilder position such that the instructions after CodeGenIP are moved to another basic block and before returning create a new branch instruction to the split block.Some utility functions such as `splitBB` are supporting correct splitting of BasicBlocks, independent of whether they have a terminator or not, returning/setting the InsertPoint of an IRBuilder to the end of split predecessor block, and optionally omitting creating a branch to the split successor block to be added later.Reviewed By: kiranchandramohanDifferential Revision: https://reviews.llvm.org/D118409 List of files: /llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp Tue, 26 Apr 2022 18:35:13 +0000 Michael Kruse <llvm-project@meinersbur.de> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#2d92ee97 Reapply "[OpenMP] Refactor OMPScheduleType enum."This reverts commit af0285122f306573d9bcc4c4ad7f904cfdd4d869.The test "libomp::loop_dispatch.c" on builderopenmp-gcc-x86_64-linux-debian fails from time-to-time.See #54969.

The enum values have an internal structure, namely each scheduling algorithm (e.g.) exists in four variants: unordered, orderend, normerge unordered, and nomerge ordered.This patch (basically a followup to D114940) splits the "ordered" and "nomerge" bits into separate flags, as was already done for the "monotonic" and "nonmonotonic", so we can apply bit flags operations on them. It also now contains all possible combinations according to kmp's sched_type. Deriving of the OMPScheduleType enum from clause parameters has been moved form MLIR's OpenMPToLLVMIRTranslation.cpp to OpenMPIRBuilder to make available for clang as well. Since the primary purpose of the flag is the binary interface to libomp, it has been made more private to LLVMFrontend. The primary interface for generating worksharing-loop using OpenMPIRBuilder code becomes `applyWorkshareLoop` which derives the OMPScheduleType automatically and calls the appropriate emitter function.While this is mostly a NFC refactor, it still applies the following functional changes: * The logic from OpenMPToLLVMIRTranslation to derive the OMPScheduleType also applies to clang. Most notably, it now applies the nonmonotonic flag for non-static schedules by default. * In OpenMPToLLVMIRTranslation, the nonmonotonic default flag was previously not applied if the simd modifier was used. I assume this was a bug, since the effect was due to `loop.schedule_modifier()` returning `mlir::omp::ScheduleModifier::none` instead of `llvm::Optional::None`. * In OpenMPToLLVMIRTranslation, the nonmonotonic default flag was set even if ordered was specified, in breach to what the comment before citing the OpenMP specification says. I assume this was an oversight.The ordered flag with parameter was not considered in this patch. Changes will need to be made (e.g. adding/modifying function parameters) when support for it is added. The lengthy names of the enum values can be discussed, for the moment this is avoiding reusing previously existing enum value names such as `StaticChunked` to avoid confusion.Reviewed By: peixinDifferential Revision: https://reviews.llvm.org/D123403 List of files: /llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp Mon, 18 Apr 2022 15:58:53 +0000 Michael Kruse <llvm-project@meinersbur.de> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#c082ca16 [OpenMPIRBuilder] Detect and fix ambiguous InsertPoints for createSections.Follow-up on D117226 for createSections.Reviewed By: shraiyshDifferential Revision: https://reviews.llvm.org/D117835 List of files: /llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp Tue, 05 Apr 2022 01:13:02 +0000 Michael Kruse <llvm-project@meinersbur.de> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#3e7415a0 [OMPIRBuilder] Support ordered clause specified without parameterThis patch supports ordered clause specified without parameter inworksharing-loop directive in the OpenMPIRBuilder and lowering MLIR toLLVM IR.Reviewed By: MeinersburDifferential Revision: https://reviews.llvm.org/D114940 List of files: /llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp Fri, 01 Apr 2022 08:17:29 +0000 Peixin-Qiao <qiaopeixin@huawei.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#8722c12c [mlir][OpenMP][IRBuilder] Add support for nowait on single constructThis patch adds the nowait parameter to `createSingle` inOpenMPIRBuilder and handling for IR generation from OpenMP Dialect.Also added tests for the same.Reviewed By: ftynseDifferential Revision: https://reviews.llvm.org/D122371 List of files: /llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp Thu, 24 Mar 2022 16:46:43 +0000 Shraiysh Vaishay <Shraiysh.Vaishay@amd.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#31486a9f [mlir][OpenMP] Added translation from `omp.atomic.capture` to LLVM IRThis patch adds translation from `omp.atomic.capture` to LLVM IR.
