Member Function Documentation

◆ get()

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

Most code should get the globals via this static accessor.

Definition at line 33 of file Globals.h.

Referenced by 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 40 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 40 of file IRModule.cpp.

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

◆ lookupAttributeBuilder()

std::optional< nb::callable > PyGlobals::lookupAttributeBuilder ( const std::string &  attributeKind)

Returns the custom Attribute builder for Attribute kind.

Definition at line 123 of file IRModule.cpp.

◆ lookupDialectClass()

std::optional< nb::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 157 of file IRModule.cpp.

References loadDialectModule().

◆ lookupOperationClass()

std::optional< nb::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 171 of file IRModule.cpp.

References loadDialectModule().

Referenced by mlir::python::PyOperation::createOpView().

◆ lookupTypeCaster()

std::optional< nb::callable > PyGlobals::lookupTypeCaster ( MlirTypeID  mlirTypeID,
MlirDialect  dialect 
)

Returns the custom type caster for MlirTypeID mlirTypeID.

Definition at line 132 of file IRModule.cpp.

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

◆ lookupValueCaster()

std::optional< nb::callable > PyGlobals::lookupValueCaster ( MlirTypeID  mlirTypeID,
MlirDialect  dialect 
)

Returns the custom value caster for MlirTypeID mlirTypeID.

Definition at line 144 of file IRModule.cpp.

◆ registerAttributeBuilder()

void PyGlobals::registerAttributeBuilder ( const std::string &  attributeKind,
nanobind::callable  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 69 of file IRModule.cpp.

◆ registerDialectImpl()

void PyGlobals::registerDialectImpl ( const std::string &  dialectNamespace,
nanobind::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 100 of file IRModule.cpp.

◆ registerOperationImpl()

void PyGlobals::registerOperationImpl ( const std::string &  operationName,
nanobind::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 111 of file IRModule.cpp.

◆ registerTypeCaster()

void PyGlobals::registerTypeCaster ( MlirTypeID  mlirTypeID,
nanobind::callable  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 82 of file IRModule.cpp.

◆ registerValueCaster()

void PyGlobals::registerValueCaster ( MlirTypeID  mlirTypeID,
nanobind::callable  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.

◆ setDialectSearchPrefixes()

void mlir::python::PyGlobals::setDialectSearchPrefixes ( std::vector< std::string >  newValues)
