Member Function Documentation

◆ attachDiagnosticHandler()

py::object PyMlirContext::attachDiagnosticHandler ( pybind11::object callback )

Attaches a Python callback as a diagnostic handler, returning a registration object (internally a PyDiagnosticHandler).

Definition at line 687 of file IRCore.cpp.

References get(), mlir::python::PyDiagnostic::invalidate(), mlirContextAttachDiagnosticHandler(), mlirLogicalResultFailure(), and mlirLogicalResultSuccess().

◆ clearLiveOperations()

size_t PyMlirContext::clearLiveOperations ( )

Clears the live operations map, returning the number of entries which were invalidated.

To be used as a safety mechanism so that API end-users can't corrupt by holding references they shouldn't have accessed in the first place.

Definition at line 639 of file IRCore.cpp.

◆ clearOperation()

void PyMlirContext::clearOperation ( MlirOperation op )

Removes an operation from the live operations map and sets it invalid.

This is useful for when some non-bindings code destroys the operation and the bindings need to made aware. For example, in the case when pass manager is run.

Definition at line 647 of file IRCore.cpp.

◆ clearOperationsInside()

void PyMlirContext::clearOperationsInside ( PyOperationBase & op )

Clears all operations nested inside the given op using clearOperation(MlirOperation).

Definition at line 655 of file IRCore.cpp.

◆ contextEnter()

pybind11::object PyMlirContext::contextEnter ( )

Enter and exit the context manager.

Definition at line 677 of file IRCore.cpp.

◆ contextExit()

void PyMlirContext::contextExit	(	const pybind11::object &	excType,
		const pybind11::object &	excVal,
		const pybind11::object &	excTb
	)

Definition at line 681 of file IRCore.cpp.

References mlir::python::PyThreadContextEntry::popContext().

◆ createFromCapsule()

py::object PyMlirContext::createFromCapsule ( pybind11::object capsule )

static

Creates a PyMlirContext from the MlirContext wrapped by a capsule.

Note that PyMlirContext instances are uniqued, so the returned object may be a pre-existing object. Ownership of the underlying MlirContext is taken by calling this function.

Definition at line 601 of file IRCore.cpp.

References forContext(), mlirContextIsNull(), mlirPythonCapsuleToContext(), and mlir::python::PyObjectRef< T >::releaseObject().

◆ createNewContextForInit()

PyMlirContext * PyMlirContext::createNewContextForInit ( )

static

For the case of a python init (py::init) method, pybind11 is quite strict about needing to return a pointer that is not yet associated to an py::object.

Since the forContext() method acts like a pool, possibly returning a recycled context, it does not satisfy this need. The usual way in python to accomplish such a thing is to override new, but that is also not supported by pybind11. Instead, we use this entry point which always constructs a fresh context (which cannot alias an existing one because it is fresh).

Definition at line 608 of file IRCore.cpp.

References mlirContextCreateWithThreading(), and PyMlirContext().

◆ forContext()

PyMlirContextRef PyMlirContext::forContext ( MlirContext context )

static

Returns a context reference for the singleton PyMlirContext wrapper for the given context.

py::object PyMlirContext::getCapsule ( )

Gets a capsule wrapping the void* within the MlirContext.

◆ getRef()

PyMlirContextRef mlir::python::PyMlirContext::getRef ( )

inline

Gets a strong reference to this context, which will ensure it is kept alive for the life of the reference.

Definition at line 187 of file IRModule.h.

◆ setEmitErrorDiagnostics()

void mlir::python::PyMlirContext::setEmitErrorDiagnostics ( bool value )

inline

Controls whether error diagnostics should be propagated to diagnostic handlers, instead of being captured by ErrorCapture.
