convertInstructionImpl()

static LogicalResult convertInstructionImpl ( OpBuilder &  odsBuilder, llvm::Instruction *  inst, ModuleImport &  moduleImport  )

static

Converts the LLVM instructions that have a generated MLIR builder.

Using a static implementation method called from the module import ensures the builders have to use the moduleImport argument and cannot directly call import methods. As a result, both the intrinsic and the instruction MLIR builders have to use the moduleImport argument and none of them has direct access to the private module import methods.

diagMD()

static std::string diagMD ( const llvm::Metadata *  node, const llvm::Module *  module  )

static

getGlobalComdatOpName()

static constexpr StringRef getGlobalComdatOpName ( )

staticconstexpr

Returns the symbol name for the module-level comdat operation.

It must not conflict with the user namespace.

Definition at line 82 of file ModuleImport.cpp.

getGlobalCtorsVarName()

static constexpr StringRef getGlobalCtorsVarName ( )

staticconstexpr

Returns the name of the global_ctors global variables.

Definition at line 71 of file ModuleImport.cpp.

getGlobalDtorsVarName()

static constexpr StringRef getGlobalDtorsVarName ( )

staticconstexpr

Returns the name of the global_dtors global variables.

Definition at line 76 of file ModuleImport.cpp.

getLLVMSyncScope()

static StringRef getLLVMSyncScope ( llvm::Instruction *  inst )

static

Converts the sync scope identifier of inst to the string representation necessary to build an atomic LLVM dialect operation.

Returns the empty string if the operation has either no sync scope or the default system-level sync scope attached. The atomic operations only set their sync scope attribute if they have a non-default sync scope attached.

Definition at line 91 of file ModuleImport.cpp.

getPositionFromIndices()

static SmallVector<int64_t> getPositionFromIndices ( ArrayRef< unsigned >  indices )

static

Converts an array of unsigned indices to a signed integer position array.

getScalarConstantAsAttr()

static Attribute getScalarConstantAsAttr ( OpBuilder &  builder, llvm::Constant *  constScalar  )

static

Returns an integer or float attribute for the provided scalar constant constScalar or nullptr if the conversion fails.

getSequenceConstantAsAttrs()

static SmallVector<Attribute> getSequenceConstantAsAttrs ( OpBuilder &  builder, llvm::ConstantDataSequential *  constSequence  )

static

Returns an integer or float attribute array for the provided constant sequence constSequence or nullptr if the conversion fails.

getVectorTypeForAttr()

static Type getVectorTypeForAttr ( Type  type, ArrayRef< int64_t >  arrayShape = {}  )

static

Returns type if it is a builtin integer or floating-point vector type that can be used to create an attribute or nullptr otherwise.

If provided, arrayShape is added to the shape of the vector to create an attribute that matches an array of vectors.
