Member Function Documentation

get()

static PyGlobals& mlir::python::PyGlobals::get ( )

inlinestatic

Most code should get the globals via this static accessor.

Referenced by mlir::python::PyConcreteType< DerivedTy, BaseTy >::bind(), mlir::python::PyConcreteAttribute< DerivedTy, BaseTy >::bind(), mlir::python::PyOperation::createOpView(), and mlir::python::PyValue::maybeDownCast().

getDialectSearchPrefixes()

std::vector<std::string>& mlir::python::PyGlobals::getDialectSearchPrefixes ( )

inline

Get and set the list of parent modules to search for dialect implementation classes.

Definition at line 41 of file Globals.h.

loadDialectModule()

bool PyGlobals::loadDialectModule

(

llvm::StringRef

dialectNamespace

)

Loads a python module corresponding to the given dialect namespace.

No-ops if the module has already been loaded or is not found. Raises an error on any evaluation issues. Note that this returns void because it is expected that the module contains calls to decorators and helpers that register the salient entities. Returns true if dialect is successfully loaded.

Definition at line 39 of file IRModule.cpp.

Referenced by lookupDialectClass(), lookupOperationClass(), lookupTypeCaster(), and lookupValueCaster().

lookupAttributeBuilder()

std::optional< py::function > PyGlobals::lookupAttributeBuilder

(

const std::string &

attributeKind

)

Returns the custom Attribute builder for Attribute kind.

Definition at line 124 of file IRModule.cpp.

lookupDialectClass()

std::optional< py::object > PyGlobals::lookupDialectClass

(

const std::string &

dialectNamespace

)

Looks up a registered dialect class by namespace.

Note that this may trigger loading of the defining module and can arbitrarily re-enter.

Definition at line 158 of file IRModule.cpp.

References loadDialectModule().

lookupOperationClass()

std::optional< pybind11::object > PyGlobals::lookupOperationClass

(

llvm::StringRef

operationName

)

Looks up a registered operation class (deriving from OpView) by operation name.

Note that this may trigger a load of the dialect, which can arbitrarily re-enter.

Definition at line 172 of file IRModule.cpp.

References loadDialectModule().

lookupTypeCaster()

std::optional< py::function > PyGlobals::lookupTypeCaster	(	MlirTypeID	mlirTypeID,
		MlirDialect	dialect
	)

Returns the custom type caster for MlirTypeID mlirTypeID.

Definition at line 133 of file IRModule.cpp.

References loadDialectModule(), mlirDialectGetNamespace(), and unwrap().

lookupValueCaster()

std::optional< py::function > PyGlobals::lookupValueCaster	(	MlirTypeID	mlirTypeID,
		MlirDialect	dialect
	)

Returns the custom value caster for MlirTypeID mlirTypeID.

Definition at line 145 of file IRModule.cpp.

registerAttributeBuilder()

void PyGlobals::registerAttributeBuilder	(	const std::string &	attributeKind,
		pybind11::function	pyFunc,
		bool	replace = false
	)

Adds a user-friendly Attribute builder.

Raises an exception if the mapping already exists and replace == false. This is intended to be called by implementation code.

Definition at line 68 of file IRModule.cpp.

registerDialectImpl()

void PyGlobals::registerDialectImpl	(	const std::string &	dialectNamespace,
		pybind11::object	pyClass
	)

Adds a concrete implementation dialect class.

Raises an exception if the mapping already exists. This is intended to be called by implementation code.

Definition at line 101 of file IRModule.cpp.

registerOperationImpl()

void PyGlobals::registerOperationImpl	(	const std::string &	operationName,
		pybind11::object	pyClass,
		bool	replace = false
	)

Adds a concrete implementation operation class.

Raises an exception if the mapping already exists and replace == false. This is intended to be called by implementation code.

Definition at line 112 of file IRModule.cpp.

registerTypeCaster()

void PyGlobals::registerTypeCaster	(	MlirTypeID	mlirTypeID,
		pybind11::function	typeCaster,
		bool	replace = false
	)

Adds a user-friendly type caster.

Raises an exception if the mapping already exists and replace == false. This is intended to be called by implementation code.

Definition at line 81 of file IRModule.cpp.

registerValueCaster()

void PyGlobals::registerValueCaster	(	MlirTypeID	mlirTypeID,
		pybind11::function	valueCaster,
		bool	replace = false
	)

Adds a user-friendly value caster.

Raises an exception if the mapping already exists and replace == false. This is intended to be called by implementation code.
