◆ mlirExternalPassSignalFailure()

void mlirExternalPassSignalFailure ( MlirExternalPass pass)

Print a textual MLIR pass pipeline by sending chunks of the string representation and forwarding userData to callback`.

Note that the / callback may be called several times with consecutive chunks of the string. MLIR_CAPI_EXPORTED void mlirPrintPassPipeline(MlirOpPassManager passManager, MlirStringCallback callback, void *userData);

/ Parse a textual MLIR pass pipeline and assign it to the provided / OpPassManager. If parsing fails an error message is reported using the / provided callback. MLIR_CAPI_EXPORTED MlirLogicalResult mlirParsePassPipeline(MlirOpPassManager passManager, MlirStringRef pipeline, MlirStringCallback callback, void *userData);

===-------------------------------------------------------------------—===// External Pass API.

This API allows to define passes outside of MLIR, not necessarily in C++, and register them with the MLIR pass management infrastructure.

===-------------------------------------------------------------------—===//

/ Structure of external MlirPass callbacks. / All callbacks are required to be set unless otherwise specified. struct MlirExternalPassCallbacks { / This callback is called from the pass is created. / This is analogous to a C++ pass constructor. void (*construct)(void *userData);

/ This callback is called when the pass is destroyed / This is analogous to a C++ pass destructor. void (*destruct)(void *userData);

/ This callback is optional. / The callback is called before the pass is run, allowing a chance to / initialize any complex state necessary for running the pass. / See Pass::initialize(MLIRContext *). MlirLogicalResult (*initialize)(MlirContext ctx, void *userData);

/ This callback is called when the pass is cloned. / See Pass::clonePass(). void *(*clone)(void *userData);

/ This callback is called when the pass is run. / See Pass::runOnOperation(). void (*run)(MlirOperation op, MlirExternalPass pass, void *userData); }; typedef struct MlirExternalPassCallbacks MlirExternalPassCallbacks;

/ Creates an external MlirPass that calls the supplied callbacks using the / supplied userData. If opName is empty, the pass is a generic operation / pass. Otherwise it is an operation pass specific to the specified pass name. MLIR_CAPI_EXPORTED MlirPass mlirCreateExternalPass( MlirTypeID passID, MlirStringRef name, MlirStringRef argument, MlirStringRef description, MlirStringRef opName, intptr_t nDependentDialects, MlirDialectHandle *dependentDialects, MlirExternalPassCallbacks callbacks, void *userData);

/ This signals that the pass has failed. This is only valid to call during / the run callback of MlirExternalPassCallbacks. See Pass::signalPassFailure().

◆ mlirOpPassManagerAddOwnedPass()

void mlirOpPassManagerAddOwnedPass ( MlirOpPassManager passManager,
MlirPass pass )

Add a pass and transfer ownership to the provided mlirOpPassManager.

If the pass is not a generic operation pass or matching the type of the provided PassManager, a new OpPassManager is implicitly nested under the provided PassManager.

MlirStringCallback callback,
void * userData )

Parse a sequence of textual MLIR pass pipeline elements and add them to the provided OpPassManager.

If parsing fails an error message is reported using the provided callback.
