Determines whether type is integer like, i.e.

it's a supported integer, an index or opaque type.

populateExpressionPatterns()

void mlir::emitc::populateExpressionPatterns

(

RewritePatternSet &

patterns

Populates patterns with expression-related patterns.

populateFuncPatterns()

void mlir::emitc::populateFuncPatterns	(	RewritePatternSet &	patterns,
		StringRef	namedAttribute
	)

Populates 'patterns' with func-related patterns.

translateToCpp()

LogicalResult mlir::emitc::translateToCpp	(	Operation *	op,
		raw_ostream &	os,
		bool	declareVariablesAtTop = false,
		StringRef	fileId = {}
	)

Translates the given operation to C++ code.

The operation or operations in the region of 'op' need almost all be in EmitC dialect. The parameter 'declareVariablesAtTop' enforces that all variables for op results and block arguments are declared at the beginning of the function. If parameter 'fileId' is non-empty, then body of emitc.file ops with matching id are emitted.
