Detailed Description

Captures attributes that affect generating LLVM-IR using the OpenMPIRBuilder and related classes.

Note that not all attributes are required for all classes or functions. In some use cases the configuration is not necessary at all, because because the only functions that are called are ones that are not dependent on the configuration.

Member Data Documentation

EmitLLVMUsedMetaInfo

std::optional<bool> llvm::OpenMPIRBuilderConfig::EmitLLVMUsedMetaInfo

Flag for specifying if LLVMUsed information should be emitted.

Definition at line 105 of file OMPIRBuilder.h.

Referenced by llvm::OpenMPIRBuilder::finalize(), and setEmitLLVMUsed().

FirstSeparator

std::optional<StringRef> llvm::OpenMPIRBuilderConfig::FirstSeparator

First separator used between the initial two parts of a name.

Definition at line 111 of file OMPIRBuilder.h.

Referenced by firstSeparator(), and setFirstSeparator().

GridValue

std::optional<omp::GV> llvm::OpenMPIRBuilderConfig::GridValue

Definition at line 116 of file OMPIRBuilder.h.

Referenced by getGridValue(), and setGridValue().

IsGPU

std::optional<bool> llvm::OpenMPIRBuilderConfig::IsGPU

Flag for specifying if the compilation is done for an accelerator.

It is set according to the architecture of the target triple and currently only true when targeting AMDGPU or NVPTX. Today, these targets can only perform the role of an OpenMP target device, so IsTargetDevice must also be true if IsGPU is true. This restriction might be lifted if an accelerator- like target with the ability to work as the OpenMP host is added, or if the capabilities of the currently supported GPU architectures are expanded.

Definition at line 102 of file OMPIRBuilder.h.

IsTargetDevice

std::optional<bool> llvm::OpenMPIRBuilderConfig::IsTargetDevice

Flag to define whether to generate code for the role of the OpenMP host (if set to false) or device (if set to true) in an offloading context.

It is set when the -fopenmp-is-target-device compiler frontend option is specified.

Definition at line 92 of file OMPIRBuilder.h.

Referenced by llvm::OpenMPIRBuilder::createTargetData(), isTargetDevice(), and setIsTargetDevice().

OpenMPOffloadMandatory

std::optional<bool> llvm::OpenMPIRBuilderConfig::OpenMPOffloadMandatory

Flag for specifying if offloading is mandatory.

Definition at line 108 of file OMPIRBuilder.h.

Referenced by openMPOffloadMandatory(), and setOpenMPOffloadMandatory().

Separator

std::optional<StringRef> llvm::OpenMPIRBuilderConfig::Separator

Separator used between all of the rest consecutive parts of s name.

Definition at line 113 of file OMPIRBuilder.h.

Referenced by separator(), and setSeparator().

TargetTriples

SmallVector<Triple> llvm::OpenMPIRBuilderConfig::TargetTriples

When compilation is being done for the OpenMP host (i.e.

IsTargetDevice = false), this contains the list of offloading triples associated, if any.
