◆ convertInstructionImpl()

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

Definition at line 63 of file ModuleImport.cpp.

◆ 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 83 of file ModuleImport.cpp.

◆ getGlobalCtorsVarName()

static constexpr StringRef getGlobalCtorsVarName ( )
staticconstexpr

Returns the name of the global_ctors global variables.

Definition at line 72 of file ModuleImport.cpp.

◆ getGlobalDtorsVarName()

static constexpr StringRef getGlobalDtorsVarName ( )
staticconstexpr

Returns the name of the global_dtors global variables.

Definition at line 77 of file ModuleImport.cpp.

Referenced by mlir::LLVM::ModuleImport::convertGlobals().

◆ 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 92 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.

Definition at line 112 of file ModuleImport.cpp.

◆ getScalarConstantAsAttr()

static TypedAttr 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

◆ getTopologicallySortedBlocks()

static SetVector<llvm::BasicBlock *> getTopologicallySortedBlocks ( ArrayRef< llvm::BasicBlock * >  basicBlocks)
static

Get a topologically sorted list of blocks for the given basic blocks.

Definition at line 144 of file ModuleImport.cpp.

◆ 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.

Definition at line 676 of file ModuleImport.cpp.

◆ isMetadataKillLocation()

static bool isMetadataKillLocation ( llvm::DbgVariableIntrinsic *  dbgIntr)
static

Checks if dbgIntr is a kill location that holds metadata instead of an SSA value.

Definition at line 1979 of file ModuleImport.cpp.

◆ isScalarType()

static bool isScalarType ( Type  type)
static

Returns if type is a scalar integer or floating-point type.
