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.

EmitLLVMUsedMetaInfo

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

Flag for specifying if LLVMUsed information should be emitted.

FirstSeparator

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

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

GridValue

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

Definition at line 135 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.

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.

OpenMPOffloadMandatory

Separator

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

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

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.
