class CGOpenMPRuntime::TargetDataInfo

Declaration

class CGOpenMPRuntime::TargetDataInfo { /* full declaration omitted */ };

Description

Struct that keeps all the relevant information that should be kept throughout a 'target data' region.

Declared at: clang/lib/CodeGen/CGOpenMPRuntime.h:1657

Member Variables

private bool RequiresDevicePointerInfo = false

Set to true if device pointer information have to be obtained.

private bool SeparateBeginEndCalls = false

Set to true if Clang emits separate runtime calls for the beginning and end of the region. These calls might have separate map type arrays.

public llvm::Value* BasePointersArray = nullptr

The array of base pointer passed to the runtime library.

public llvm::Value* PointersArray = nullptr

The array of section pointers passed to the runtime library.

public llvm::Value* SizesArray = nullptr

The array of sizes passed to the runtime library.

public llvm::Value* MapTypesArray = nullptr

The array of map types passed to the runtime library for the beginning of the region or for the entire region if there are no separate map types for the region end.

public llvm::Value* MapTypesArrayEnd = nullptr

The array of map types passed to the runtime library for the end of the region, or nullptr if there are no separate map types for the region end.

public llvm::Value* MappersArray = nullptr

The array of user-defined mappers passed to the runtime library.

public llvm::Value* MapNamesArray = nullptr

The array of original declaration names of mapped pointers sent to the runtime library for debugging

public bool HasMapper = false

Indicate whether any user-defined mapper exists.

public unsigned int NumberOfPtrs = 0U

The total number of pointers passed to the runtime library.

public llvm::DenseMap<const ValueDecl*, Address> CaptureDeviceAddrMap

Map between the a declaration of a capture and the corresponding base pointer address where the runtime returns the device pointers.
