Member Typedef Documentation

◆ CallBackT

using CGRAOmp::DFGPassBuilder::CallBackT = std::function<bool(StringRef, DFGPassManager &)>

Constructor & Destructor Documentation

◆ DFGPassBuilder()

DFGPassBuilder::DFGPassBuilder ( )

Member Function Documentation

◆ parsePassPipeline()

Error DFGPassBuilder::parsePassPipeline	(	DFGPassManager &	DPM,
		ArrayRef< std::string >	PipelineText
	)

Parsing the pipeline setting for DFG optimization.

Parameters

DPM	DFGPassManager
PipelineText	a list of name of passes to be applied

Returns: Error is retured if a name of pass does not match any registered passes

◆ registerPipelineParsingCallback()

void DFGPassBuilder::registerPipelineParsingCallback ( const CallBackT & C )

Register a call back function to parse the pass pipeline.

Parameters

C	Call back function

◆ search_callback()

Error DFGPassBuilder::search_callback ( )

private

Looking up call back function in the dynamic libraries.

Returns: Error in either case, a failure in loading the dynmic lib or no call back function named getDFGPassPluginInfo

An exmaple of the call back function:

extern "C" ::CGRAOmp::DFGPassPluginLibraryInfo getDFGPassPluginInfo() {
    return { "Plugin name", 
        [](DFGPassBuilder &PB) {
            PB.registerPipelineParsingCallback(
                [](StringRef Name, DFGPassManager &PM) {
                    if (Name == "my-dfg-pass") {
                        PM.addPass(MyDFGPass());
                        return true;
                    }
                    return false;
                }
            );
        }
    };
